�How to Use this Guide

CPW Area Office Phone Directory

This guide has been developed for Colorado's livestock owners and is
intended to be used as a general reference guide to assist with identifying
livestock depredations. It contains typical attack and feeding characteristics
of various predators, CPW Office contact information, and general livestock
compensation information.

CPW offices are open Monday–Friday, 8am-5pm. For after-hours emergencies,
contact the Colorado State Patrol at (303) 239-4501 or your local Sheriff’s
Department.

It does not describe every situation that might occur or other causes of
livestock mortality. Local CPW staff are skilled in investigating livestock
depredations and are your best resource to determine if your livestock was
depredated.

Common Attack Zones on Adult
Livestock: Tail, Hindquarter/Groin, Flank,
Behind and Under Front Leg.

ATTACK CHARACTERISTICS

FEEDING CHARACTERISTICS

ATTACK CHARACTERISTICS

Ϝ Wolves often attack from behind.
Ϝ Canine rake marks are often found on
the animal's hocks and hindquarters.
Ϝ The tail may be missing or be stripped
of hide.
Ϝ Wolves may also attack on the head,
throat, front legs, and flank areas.
Ϝ Multiple kills of sheep in a single event
can occur.

⬓ Wolves may consume entire carcass.
⬓ Wolves consume large amounts during
each feeding and preferential feeding
patterns may not always be evident.
⬓ Wolves can crush and consume large
bones of adult livestock.
⬓ Crushed skulls, severed spines and
disembowelment common in smaller
livestock depredations.

Ϝ Will hunt as individuals or in packs,
attacking prey from the rear, flank or throat
areas.
Ϝ Sheep, goats and young calves are more
susceptible to coyote predation, since
coyotes prefer smaller prey.
Ϝ Will often attack the throat to suffocate
the animal. Multiple puncture wounds to
throat indicate the coyote re-adjusted its grip
during the attack.

FEEDING CHARACTERISTICS
⬓ Feeding leaves jagged lacerations
and splintered/chewed ribs,
especially on smaller animals.
⬓ The feeding site is often very messy
and littered with tufts of hair, blood
and tissue.
⬓ Often mark kill sites by urinating
and defecating soon after feeding.

COLORADO PARKS &amp; WILDLIFE • A PRODUCER'S GUIDE TO LIVESTOCK DEPREDATIONS

ATTACK CHARACTERISTICS

FEEDING CHARACTERISTICS

Ϝ Dogs attack indiscriminately and are
inefficient, sloppy killers.
Ϝ Trauma is widespread due to multiple
bites to any part of the animal’s body.
Ϝ Motivated by the enjoyment of the
chase rather than the need to feed.

⬓ Dogs Seldom feed on the carcass: If
feeding occurred, carcass may be at or
very near kill site.
⬓ Messy feeding characteristics; Ragged or
frayed wounds and lacerations.
⬓ Tracks and teeth spacing highly variable
due to many breeds and sizes.

ATTACK CHARACTERISTICS

FEEDING CHARACTERISTICS

Ϝ Smaller animals: Bite the head or neck
and twist or pull to break the spine.
Ϝ Large animals: Bite the throat and
windpipe to suffocate the animal.
Ϝ Lions are normally strong enough to
maintain a hold on their prey with
minimal re-adjustment.
Ϝ Lacerations may not show marks from
all five of the lion’s claws.
Ϝ Claw marks are knife-like, with very
clean edges.

⬓ Lions prefer viscera to meat and will
generally feed on the heart, lungs and
liver first but can also feed on the neck,
shoulders or hindquarters first.
⬓ Before feeding, lions commonly pluck
out the wool or hair from the hide.
⬓ Unlike bears, lions do not normally
eat the stomach, intestines or their
contents.
⬓ Lions commonly cache carcasses with
available debris and re-visit the carcass
multiple times to feed.

Ϝ Bears will not usually pursue their prey
over long distances, but once the animal is
killed, they may drag it some distance to
feed elsewhere.
Ϝ Bears are known to prey on all age classes
of adult livestock but prefer calves, sheep
and pigs.
Ϝ Bears will attack the head, neck and back:
Lacerations may be left by the bear’s teeth
when it bites and by its claws when it
attempts to grip its prey during the attack.
Ϝ Dull, non-retractable claws do not cleanly
cut hide and tissue like the claws of a lion.

⬓ Bears will take advantage of any food
source given the opportunity.

⬓ Multiple kills of sheep in a single event
are relatively common.
⬓ Usually feed on meat before viscera but
not always.
⬓ Unlike wolves and mountain lions,
bears often eat the stomach contents
(rumen) of livestock.
⬓ Bears rarely scatter remains or attempt
to cover carcasses.

�Canine Track Comparison
Depending on substrate, wolf tracks are about 5 inches long by
4 inches wide, with four symmetrical toes and identifiable claws;
coyote tracks are similar, but are only about half the size. Large
dogs can have tracks with similar dimensions to wolves.

�Feline Track Comparison
Felines have retractable claws, which rarely show in most
substrates, and the overall shape of the track tends to be wider
than they are long. Mountain lion tracks are very large, and
other carnivores like bobcats, foxes, or coyotes will leave
significantly smaller tracks.

BOBCAT

Black Bear Track
Black bears have 5 rounded toes with large, blunt claws. The track is
asymmetrical. Palm pad is wide, and curved and gets larger to the outside.
The mid-portion of the front tracks often does not register, and there is a small
round heel pad that sometimes registers behind the palm pad.

Colorado Wolf Restoration and Management Plan

�Executive Summary
Through the passage of Ballot Initiative 114 in the November 2020 state election, codified at Colo. Rev.
Stat. § 33-2-105.8, as amended (attached as Appendix A), the voters of Colorado mandated that the Colorado Parks and Wildlife Commission (hereafter, Commission) restore the gray wolf (Canis lupus) to
the state. This Colorado Wolf Restoration and Management Plan (hereafter Plan) describes how this will
be achieved and fulfills the planning components of the statutory requirements of CRS 33-2-105.8.
Chapter 1 describes the background for how and why this
plan was developed.
Beginning in the summer of 2019, the Rocky Mountain Wolf Action Fund circulated petitions asking Colorado voters to place the
following question on the ballot: “Shall there be a change to the Colorado Revised Statutes concerning the restoration of gray wolves
through their reintroduction on designated lands in Colorado located west of the Continental Divide, and, in connection therewith,
requiring the Colorado Parks and Wildlife Commission, after holding statewide hearings and using scientific data, to implement a plan
to restore and manage gray wolves; prohibiting the commission
from imposing any land, water, or resource use restrictions on private landowners to further the plan; and requiring the commission
to fairly compensate owners for losses of livestock caused by gray
wolves?” (Colorado Secretary of State 2020).
A total of 215,370 signatures were submitted to the Colorado Secretary of State office on 10 December 2019, and subsequently certified on 06 January 2020, indicating that this issue would appear on
the ballot in November 2020. This became Proposition 114. The
Proposition passed with 50.91 percent of votes cast (1,590,299) voting in favor, and 49.09 percent of the voters (1,533,313) opposing
(Colorado Secretary of State 2020). Support for the ballot measure
was inconsistent across the state. The resulting state statute (CRS 332-105.8) requires the Colorado Parks and Wildlife Commission to
develop a plan to restore and manage gray wolves in Colorado and
take steps necessary to begin reintroductions by December 31, 2023.
The primary goal of this Plan is:
To recover and maintain a viable, self-sustaining wolf population in
Colorado, while concurrently working to minimize wolf-related conflicts with domestic animals, other wildlife, and people.
The Commission was responsible for developing the Plan per
state statute. The Commission served as the decision-making body
responsible for approving the Plan. The Commission and the Colorado Division of Parks and Wildlife (Division), collectively CPW,
convened a Technical Working Group (TWG; Appendix B) and a
Stakeholder Advisory Group (SAG; Appendix C) to assist in making
recommendations as the Plan was developed. A professional facilitator (Keystone Policy Center, hereafter Keystone) was hired to manage these processes, as well as the public comment process.
Chapter 2 describes key issues for conservation and management of wolves in Colorado.
This Plan is predicated on managing wolves in Colorado using “impact-based” management within an adaptive management framework
that will allow CPW maximum flexibility to manage wolves. An adaptive management framework incorporates monitoring and evaluation
components in an ongoing effort that helps participants accumulate
knowledge regarding the system of concern (Walters 1986).
i

Fundamentally, impact-based management can be summarized
by one of the core tenets presented by the SAG:
• If wolves are creating conflict, manage to resolve the problem.
When conflicts occur, they should be addressed on a case-bycase basis using a combination of appropriate management
tools, including education, non-lethal conflict minimization
techniques, lethal take of wolves, and damage payments. Proactive and reactive non-lethal conflict minimization techniques should be encouraged and explored as a first line of
defense, with consideration of individual and community-level approaches. Lethal management should not generally
be the initial response to conflicts, however there may be certain conditions under which lethal removal of wolves may be
used first to support effective conflict management.
Another key assumption is that wolves will have both positive and
negative impacts.
• Positive impacts, where they occur, should be recognized and
fostered, and may include, but are not limited to: providing
complementary offtake of ungulates in management units
where they are overpopulated; dispersal of wild ungulates
that may result in habitat improvement due to less herbivory
on vegetative communities; selective removal of individual
diseased animals from herds; and social, economic or
non-monetary values, such as intrinsic value, existence value,
and other possible values for present and future generations.
• Negative impacts could include, but are not limited to: depredation and harassment of livestock, herd dogs and guard animals; loss of pets and hobby animals; concentration of wild
ungulates on private lands possibly resulting in property
damage; reduced ungulate hunting or viewing opportunities
and related economic considerations; reduced hunting license sales resulting in a reduction in recreational opportunity and decreased revenue for wildlife management; and
declines in ungulate populations or in ungulate recruitment
rates. Some negative impacts may be low on a statewide scale
but can be acute on a local or individual scale, with social and
economic impacts for those that are affected.
A successful restoration program for wolves in Colorado requires
focus on several key issues for conservation and management. CPW
identified seven key issues that are considered most significant for the
future of wolf conservation and management: 1) social tolerance for
wolves and economic impacts, 2) wolf recovery, 3) wolf management
with respect to wolf-livestock interactions, 4) wolf management with
respect to wolf-ungulate interactions, 5) wolf interactions with other
wildlife species, 6) wolves and human safety concerns, and 7) monitoring and research. Each of these are detailed in this chapter.
Colorado Parks and Wildlife

�Chapter 3 describes the restoration implementation.
It is anticipated that wolf reintroduction efforts will require the
transfer of about 30 to 50 wolves, total, over a 3 to 5 year time frame.
It is desirable to source wolves from the northern Rockies states
(Idaho, Montana, and Wyoming) or other suitable donor sites (Oregon, Washington, as recommended by the TWG) with assistance
from other state wildlife management agencies. Based on the TWG
recommendations, CPW will aim to capture 10 to 15 wild wolves
annually from several different packs over the course of 3 to 5 years
by trapping, darting, or net gunning in the fall and winter. By reference, the TWG recommendations for Restoration Logistics (Appendix B) are incorporated into this plan, and will guide actions taken
by CPW as work to restore gray wolf populations to the state is implemented.
Within Colorado, preliminary release locations are constrained by
several geographic criteria. State statute requires that wolves be released only west of the Continental Divide. Scientists found that
wolves released in Yellowstone and central Idaho in the mid-1990s
moved substantial distances in the months immediately after release
(average distance was approximately 50 miles, ranging from approximately 22 to 140 miles from the release sites). Because of this, releases in Colorado will occur a minimum of 60 miles from
Colorado’s borders with Wyoming, Utah, New Mexico, as well as a
similar buffer, as requested by the Southern Utes, of sovereign tribal
lands in southwestern Colorado.
There is an immediate need for post-release monitoring to assess
and modify reintroduction protocols, if necessary, to ensure the
highest probability of survival and site fidelity for released animals.
All released wolves will be monitored using satellite GPS collars,
which will inform managers on survival and dispersal, as well as future release protocols.
Chapter 4 describes the State recovery metrics and thresholds
for wolves in Colorado.
As of February 10, 2022, wolves in Colorado are listed as endangered under the federal Endangered Species Act (ESA). This Plan
does not replace a federal recovery plan, nor does it outline federal
recovery goals. As this Plan is implemented, CPW will work in cooperation with the United States Fish and Wildlife Service (USFWS).
Wolves will be managed within Colorado using a phased approach, based on the minimum number of animals known to be
present in the state. These phases correspond with status of the species on the Colorado Threatened and Endangered Species list.
A minimum wintertime count is the metric that will be monitored
in the early phases of reintroduction. This count will include all
wolves in the state, whether they are wolves that have naturally migrated into the state and their progeny, as well as those that were reintroduced. Any wolf anywhere in the state will count towards the
minimum count.
This Plan authorizes downlisting of wolves from State Endangered
(Phase 1) to State Threatened (Phase 2) when CPW biologists document a minimum wintertime count of 50 wolves anywhere in the
state for four successive years. It authorizes delisting from the State
Threatened and Endangered Species list and reclassification as nongame wildlife (Phase 3) when a minimum count of at least 150
wolves anywhere in Colorado is observed for 2 successive years, or a
minimum count of at least 200 wolves anywhere in Colorado is observed, with no temporal requirement. At the time that the Parks
and Wildlife Commission is considering delisting the species, CPW
will conduct a Population Viability Analysis, or similar population
modeling effort. This would be done to assess the extinction probability of the wolf population in Colorado, using Colorado-specific
demographic parameters gained from research and monitoring the
population in the state in the years between reintroduction and reColorado Wolf Restoration and Management Plan

covery. The long term management of wolves can only be framed in
general terms at this time because forecasting the details of this future is impossible using currently available information.
Minimum counts for delisting are not intended and should not be
interpreted as population objectives or maximum target populations.
Chapter 5 describes wolf management in Colorado.
All management of wolves in Colorado will be done in compliance with all state and federal laws and regulations. The Commission may pass regulations related to this Plan. In the event of any
conflicts between the Plan and such regulations, such regulations
will control.
Concurrent with this planning process, the United States Fish and
Wildlife Service (USFWS) has embarked on a rulemaking process
designed to provide management flexibility by designating Colorado’s wolves as an experimental population under section 10(j) of the
federal ESA. CPW and USFWS anticipate that the resulting 10(j)
rule will take effect prior to the reintroduction of wolves into the
state, as was done when wolves were reintroduced into the northern
Rocky Mountains in the mid-1990s. The 10(j) rule provides management flexibility that is a critical component to the success of this
Plan and on which other components of the Plan depend.
Following reintroduction, some forms of aversive conditioning
and lethal take will be necessary in order to protect human safety, reduce livestock depredation, or to mitigate substantial risks to or effects on ungulates will be necessary management tools. These
management options are limited, however, while the gray wolf is
listed as state or federal endangered or threatened. If the Colorado
state listing status, Commission regulation, and ESA legal status of
wolves were to change, including the anticipated adoption by
USFWS of a 10(j) rule to direct management of wolves in the state,
CPW expects to have increased management flexibility, including
authority to lethally remove wolves for management purposes consistent with this Plan.
Not all impacts can be predicted, and that future management
flexibility is crucial for adaptively managing impacts as they arise.
With such uncertainty, the full gamut of potential management actions cannot be comprehensively identified this Plan.
Three primary categories of conflict and specific management
considerations are described in this Plan. The three categories of impacts are: 1) Livestock Interactions, 2) Wildlife Species Interactions,
and 3) Other Situations. For each of these categories, impact and
management tools are described. The deployment of these tools may
be affected by the Phase that the wolf population is in.
Non-lethal, non-injurious hazing of wolves includes scaring off an
animal(s) by making loud noises (e.g., confronting the animal(s)
without doing bodily harm). These tools are acceptable in all Phases
of wolf management. Non-lethal potentially injurious hazing means
scaring off a wolf (or wolves) without killing but with potential for
minor injury to the wolf (i.e., rubber bullets, etc.).
Assuming lethal take is legally authorized, this Plan describes conditions under which it may be used sooner or first to support effective conflict management, in tandem with successful recovery (e.g.,
specific scenarios, situations where non-lethal methods are unlikely
to be effective, described in Chapter 5). CPW program managers,
and if appropriate, USFWS personnel, will consider context on the
ground (biological and social considerations for population growth,
pack dynamics and distribution of wolves, recent and proximal depredations, etc.) when determining if lethal control should be applied.
A preponderance of evidence, including dead or injured livestock or
working dogs, or other physical evidence should be present, which
would lead a reasonable person to believe that a depredating wolf or
wolves were involved, or that a wolf attack on livestock or dogs was
occurring or imminent.
ii

�Chapter 6 describes wolf-livestock interactions, including
compensation and conflict minimization programs.
Providing fair compensation to livestock owners for economic
losses when livestock are injured or killed by wolves is a legally required and critically important part of the Plan. Pursuant to CRS 332-105.8 (4.5), CPW’s funding program for wolf-livestock damage
shall be appropriated from sources other than the sale of hunting
and fishing licenses or from associated federal grants. Instead, CPW
will pursue a variety of funding sources to develop sustainable and
robust wolf-livestock compensation and conflict minimization programs.
Temporary conflict minimization materials, such as turbo fladry
and scare devices, will be provided to livestock owners on a case-bycase basis and CPW may evaluate the risks to livestock when providing these materials. Risks include but are not limited to the
proximity of wolves to livestock based on monitoring data, previous
depredating/non-depredating behavior of wolf pack, whether there
has been a confirmed wolf-livestock depredation). Temporary conflict minimization materials will be loaned to livestock owners and
such materials will be delivered by CPW with instructions on their
use and installation.
CPW will also provide education/outreach to livestock owners on
other conflict minimization techniques (e.g., carcass management,
herders/range riders, herd composition, etc.) that are identified and
recommended in CPW’s Wolf Resource Guide (https://cpw.state.
co.us/Documents/Wolves/Wolf_Hands-on_Resource_Guide_Depredation_Prevention.pdf).
CPW’s wolf-livestock compensation program provides 100 percent fair market value (FMV) compensation, up to a maximum of
$15,000 per animal, for the confirmed death or injury of livestock
(cattle, horses, mules, burros, sheep, lambs, swine, llama, alpaca, and
goats, pursuant to CRS 33-2-105.8(5)) and guard/herding animals.
Conflict minimization techniques are not required to be eligible for
compensation; however, CPW will work with livestock producers to
implement conflict minimization to reduce the risk of further depredations.
Once a confirmed livestock depredation event occurs (injury or
death) to cattle or sheep, which is compensated at 100% FMV up to
$15,000, livestock owners may either apply for missing calf, yearling,
or sheep losses through a basic compensation ratio (i.e., number of
calves, yearlings, or sheep that may be claimed for each confirmed
depredation) or apply for itemized production losses (i.e., missing
calves, yearlings, or sheep, decreased weaning weights, reduced conception rates and additional losses on a case-by-case basis) by providing specific baseline documentation. This allows livestock owners
to choose whether to pursue a more simplified process versus one
that will require additional documentation to support their claim. It
would also allow livestock owners who sustain damage amounts
greater than is covered by the compensation ratio to seek production
loss compensation based on documentation they provide as part of
the claim. For each claim submitted, the livestock owner has the option to choose between the simple compensation ratio or itemization
but may not do both.

Chapter 7 describes the monitoring, ungulate management,
research and reporting components of wolf restoration and
management.
A comprehensive population monitoring program is an essential
part of the wolf conservation and management program and will be
conducted throughout the implementation of this Plan. CPW will
have primary responsibility for monitoring wolves, but collaboration
with tribes, other state and federal agencies, colleges and universities,
landowners, local governments, non-governmental organizations,
and the public will be necessary for a successful monitoring program. This coordination will be especially important when monitoring animals located on or near federal, tribal, and private lands, and
along state borders. CPW will work with the USFWS to coordinate
monitoring activities while the species remains federally listed as
threatened or endangered under the ESA.
Whereas monitoring is an effort of systematic observation/measurement to assess population status and trends, research is an effort
to test theory and use data to examine the efficacy of wildlife management techniques (or tools). Both are important for wolf management. Wolf research in Colorado will provide data that can be
interpreted and used to inform management decisions. Research
pertinent to wolf management in Colorado takes both socio-political and ecological environments into consideration.
Following reintroduction, wolf populations will be monitored to
estimate annual population size and trends. All wolves released as
part of the reintroduction will be equipped with GPS satellite collars.
As packs establish, efforts will be made to collar at least one member
of each pack with emphasis on breeding adults. The desired standard
will be to have two collars in each pack; whether this is achievable
for every pack in the state will be determined following reintroduction. There should be no expectation that every wolf in every pack
will be collared — in fact as the wolf population grows, it may become challenging to maintain one collar in every pack. While not all
packs will be expected to have collared wolves, managers will consider the proximity to livestock and history of wolf-livestock conflict
when prioritizing collaring efforts.

All wolves released as part
of the reintroduction will
be equipped with GPS
satellite collars.

There will be no Commission-imposed land, water, or resource
use restrictions placed on landowners due to the presence of wolves
or under this Plan. Federal land management agencies have sole
management discretion over their lands. CPW has no legal authority
to implement restrictions or land management prescriptions on
lands it does not own or lease. Therefore, it will be important for federal agencies and CPW to collaborate on public land use issues as
they relate to wolf management, which may include recreation, grazing management, public access, or habitat manipulation.

In addition to collars, a variety of other monitoring tools are at the
disposal of CPW biologists. Each is suited for different purposes and
the deployment of these techniques will be done in a manner that efficiently and effectively addresses the monitoring questions being
posed. Non-invasive techniques, such as winter track counts, aerial
surveys, hair sampling, scat collection, howling surveys, trail cameras, and observations by field personnel and the general public may
be used for basic population and distribution data collection.
Colorado Parks and Wildlife

�Causes of wolf mortality will also be monitored. In unexploited
populations, infectious disease, starvation, and intraspecific strife are
the primary causes of wolf mortality. Monitoring and research activities will be the primary means of identifying both human-related
and natural mortality factors for wolves. An important component
of Colorado’s wolf management program will be to adequately monitor and manage any potential sources of human-caused mortality.
Wolf health will be monitored following established CPW wildlife
health monitoring practices including both active and passive disease surveillance. During live capture operations, animals will undergo a brief physical exam to assess body condition, estimate age,
and survey for external parasites. Blood, feces, and other biological
samples will be collected from live-captured animals, when feasible,
and submitted to the CPW Wildlife Health Laboratory. Disease diagnostics will be tailored to the individual based on known health
concerns in the population, research objectives, and disease surveillance priorities. The CPW Wildlife Health Laboratory will maintain
banked serum, tissue, and other biological samples.
Monitoring prey in Colorado will also be important to the success
of this program. The effects of predators on prey populations were
one of the greatest concerns expressed by the public about wolf recovery in the northern Rockies. Recent community engagement in
Colorado suggests that those same concerns occur across much of
the state, particularly on the Western Slope. CPW extensively monitors all ungulate populations throughout the state. The reintroduction of wolves to the state will not cause any of these efforts to
diminish. In fact, CPW has already invested in expanded, pre-wolf
reintroduction ungulate monitoring, which is only likely to expand
into additional areas as wolf populations grow and disperse across
the state.

Monitoring prey in Colorado (such as these mule deer) will
be important to the success of this program.

Future research priorities for CPW will examine both the social
and ecological effects of having wolves in the state. All studies will be
designed to provide meaningful data and information that will inform on-going and future management. Research emphasis may include social tolerance for wolves, wolf ecology in Colorado,
wolf-livestock interactions, wolf-ungulate interactions, and wolf interactions with other wildlife and effects on vegetation.
Because of the intense interest in wolves and the implementation
of this Plan and because of statutory requirements, CPW will produce an annual report that summarizes required components of the
wolf restoration program activities that occurred in Colorado during
the previous year. Following the conclusion of the initial release,
CPW staff will provide updates on the plan at least annually to the
Commission on the plan’s progress, but staff can be asked to provide
an update at any time interval as there are new developments. A forColorado Wolf Restoration and Management Plan

mal review of the progress of the plan will be scheduled five years
after the completion of the reintroduction efforts.
Chapter 8 describes education, outreach, and agency coordination.
A well-informed public is essential to gray wolf conservation.
Some authorities even consider outreach efforts to be the highest
priority in restoring the species. It is crucial that wolves and wolf
management issues be portrayed in an objective and unbiased manner, and that the public receives accurate information on the species.
In this way, the solutions and compromises needed to resolve conflicts with wolves can be discussed honestly.
Colorado’s residents and visitors need access to factual information about wolves and wolf management from wildlife managers.
Likewise, to effectively manage wolves in the state, wildlife managers
need to receive information from the public on sightings, depredation events, and wolf behavior, and to factor in public opinion. With
this two-way communication, implementation of the Plan will have
a higher probability of success and both managers and the public
will have the necessary information to make conservation and management decisions to achieve Plan objectives.
CPW will continue to coordinate with other agencies and organizations to achieve wolf conservation and management objectives.
This will be accomplished by continuing to use the expertise of the
USFWS, the U.S. Department of Agriculture’s Wildlife Services Program Animal Plant Health Inspection Service (APHIS), U.S. Forest
Service (USFS), Bureau of Land Management (BLM), Colorado Department of Agriculture (CDA), tribal governments, private sector
professionals, and other state agencies. Coordination with other state
land management agencies such as the State Land Board, Colorado
State Forest Service, and others will occur as needed. Further, CPW
will engage non-governmental stakeholder organizations for input
regarding wolf management in Colorado.
Chapter 9 describes funding needs.
Implementing this Plan will create logistical and financial challenges. The Division’s capacity, through additional personnel, will
have to be increased to ensure that the Plan is properly implemented.
A variety of funding sources will be needed to conserve and manage
this native species. Management costs for wolves will likely exceed
costs currently in place for other carnivore species, such as black
bears and mountain lions. Therefore, additional funding will be required to implement wolf population monitoring and management
(and associated activities), including research, education and outreach, and compensation for livestock depredation. Livestock depredation investigations alone are likely to require a significant
investment of staff time, detracting from an already high volume of
existing responsibilities. Adequate resources for public information
and public engagement will also need to be made available to meet
the increased demands on the agency.
The Plan proposes programs that do not currently exist, both to
monitor wolf and prey populations, and to mitigate impacts of wolf
depredation on livestock. Successful implementation of the Plan will
require additional staff, financial resources, and possibly legislative
and regulatory updates to support those programs. To fully implement the elements and strategies of the Plan, a formal wolf conservation program will need to be developed within CPW, as funding and
additional staffing are made available.
As with any wildlife management program, CPW anticipates that
the wolf program will evolve through time. CPW will undertake a
thorough adaptive review of the wolf management program post-reintroduction. Cooperating state and federal agencies and tribes will
also participate. Findings of the review will inform ongoing management of wolves in Colorado.

The primary goal of this plan is to establish a self-sustaining
population of wolves. Achieving this goal will be measured
and compared against recovery objectives.

�Chapter 1:

Introduction and Background
Through the passage of Ballot Initiative 114 in the November 2020 state election, the voters of Colorado mandated that the Colorado Parks and Wildlife Commission (Commission) restore the gray wolf
(Canis lupus) to the state. This Plan describes how this will be done. The Plan must not only outline the
important management considerations for the long-term persistence of wolves but must also address the
challenges of having wolves in Colorado after such a long absence.
The Commission and the Division (jointly referred to as CPW)
will adopt and implement management programs to complete gray
wolf restoration and the establishment of a self-sustaining wolf population in Colorado. As the state wildlife agency, CPW is already engaged in activities that will facilitate wolf restoration and future
management through ungulate population monitoring, research,
and management; through the acquisition and designation of State
Wildlife Areas, and establishment of conservation easements and
other efforts to conserve and restore wildlife habitats; and by providing compensation for losses due to predation by wildlife.
As of February 10, 2022, wolves in Colorado are listed under the
federal Endangered Species Act as endangered. This Plan does not
replace a federal recovery plan, nor does it outline federal recovery
goals. CPW will work in cooperation with the USFWS as this Plan is
implemented.
Wolves are habitat generalists. Wolf distribution in Colorado will
ultimately be defined by the interaction between ecological needs
and social tolerance, as is the case for many other wildlife species
such as deer (Odocoileus spp.), elk (Cervus elaphus), black bears
(Ursus americanus), and mountain lions (Puma concolor) (Decker
and Purdy 1988, Fritts and Carbyn 1995, Bangs et al., 1998, Riley
and Decker 2000). In addition to the biological considerations, there
are important human dimensions to consider for wolf management.
Social acceptance of wolves eclipses the confines of geography, land
ownership, or land use designations just as a wolf pack’s territory
boundary transcends those same delineations. People have different
tolerance levels, values, and attitudes about wildlife, particularly large
carnivores. Furthermore, this tolerance will change in space and
time and at different spatial and temporal scales. Because of these
dynamic circumstances, an adaptive approach will help CPW implement its wolf program over the range of social acceptance values
now and in the future as values change.
Implementing this Plan will create logistical and financial challenges. Agency capacity, through additional personnel, will have to
be increased to ensure that this plan is properly implemented. A variety of funding sources will be needed to conserve and manage this
native species on equal standing with other carnivore species, such
as black bears and mountain lions. Additional funding will be required to implement wolf population monitoring and management
including compensation for livestock depredation.
While the best available science is used in formulating this Plan,
the Plan itself is not a compendium and review of the literature on
wolf biology, ecology, management, and research. There are many
sources that have thoroughly and recently compiled and reviewed
this literature. The reader is referred to these sources for this information: Mech and Boitani 2003, Smith et al., 2020, USFWS 2020.
Further, the efforts that other western states have undertaken to
draft wolf management plans for their respective states have been
immensely valuable in the drafting of this Plan for Colorado (Idaho
Legislative Wolf Oversight Committee 2002, Montana Fish Wildlife
Colorado Wolf Restoration and Management Plan

and Parks 2002, Washington Department of Fish and Wildlife 2011,
Wyoming Fish and Game Commission 2011, California Department of Fish and Wildlife 2016, Oregon Department of Fish and
Wildlife 2019).
This plan does not create regulatory changes. Those much be accomplished through rulemakings by the Commission, in accordance
with state rulemaking procedures in Title 24, C.R.S. To the extent of
a conflict between this Plan and any implementing regulations, such
regulations shall control.

Ballot Process and Description
Beginning in the summer of 2019, the Rocky Mountain Wolf Action Fund, circulated petitions asking Colorado voters to place the
following question on the ballot: “Shall there be a change to the Colorado Revised Statutes concerning the restoration of gray wolves
through their reintroduction on designated lands in Colorado located west of the continental divide, and, in connection therewith,
requiring the Colorado parks and wildlife commission, after holding
statewide hearings and using scientific data, to implement a plan to
restore and manage gray wolves; prohibiting the commission from
imposing any land, water, or resource use restrictions on private
landowners to further the plan; and requiring the commission to
fairly compensate owners for losses of livestock caused by gray
wolves?” (Colorado Secretary of State 2020).
A total of 215,370 signatures were submitted to the Colorado Secretary of State office on 10 December 2019, and subsequently certified on 06 January 2020, indicating that this issue would appear on
the ballot in November 2020. This became Proposition 114. Early
polling conducted by Colorado State University estimated that 84.0
percent of Coloradoans would vote for the proposition (Niemiec et
al., 2020). The Proposition passed with 50.91% of votes cast
(1,590,299) voting in favor, and 49.09 percent of the voters
(1,533,313) opposing (Colorado Secretary of State 2020). Support for
the ballot measure was inconsistent across the state and heavily influenced by the populous front range (Figures 1 and 2). The resulting state statute (CRS 33-2-105.8, Appendix A) requires the
Commission to develop a plan to restore and manage gray wolves in
Colorado and take steps necessary to begin reintroductions by December 31, 2023.

�Wolf Restoration and
Management Plan Development
The Commission was responsible for developing the plan per state
statute. The Commission served as the decision-making body responsible for approving the Plan. CPW convened a Technical Working Group (TWG) (Appendix B) and a Stakeholder Advisory Group
(SAG) (Appendix C) to assist in the development of this Plan. A professional facilitator (Keystone Policy Center, hereafter Keystone) was
hired to manage these processes, as well as the public comment process.
The members of the TWG were convened to review objective, science-based information as well as provide their own knowledge and
experience at the state/federal/tribal level to inform the development
of the Plan. The TWG was composed of members who brought experience in wolf reintroduction, wolf management, conflict minimization, depredation compensation, and other relevant topics. The
TWG served in an advisory capacity to CPW, offering non-binding
input into the development of Plan content. The TWG was not a decision-making body and had no authority on wolf management policy, research, or operations. The TWG operated by consensus. For
purposes of the TWG, consensus referred specifically to general
agreement, or lack of objection, that an option or alternative had sufficient technical merit to be recommended for consideration by
CPW. In the absence of consensus, dissenting views were documented (see Appendix B).
The SAG offered a broad range of perspectives and experience
and provided recommendations about the social implications associated with wolf restoration and management strategies for the Plan.
CPW leadership selected stakeholders to serve on the SAG. To enhance transparency and inclusiveness, SAG participants were recruited via an open application process that was available to anyone
who was interested. CPW Leadership used three criteria to select
stakeholders: 1) geographic representation, (2) representation of diversity of interests/perspectives/opinions, and (3) willingness to
work together to accomplish the goals outlined in the ballot initiative. Using an open application process has the potential to address
issues of inequity and power and increase legitimacy and transparency, all of which are described in the social science literature as best
practices of stakeholder engagement (Niemiec et al., 2021). The SAG
was composed of 17 voting members and 3 non-voting members.
The SAG served in an advisory capacity to CPW, offering non-binding input into the development of plan content. As with the TWG,
the SAG was not a decision-making body and had no authority on
wolf management policy, research, or operations.
Where possible, the SAG strived to make decisions based on the
consensus of all voting members. Where the SAG was able to
achieve consensus, its input received priority consideration by CPW.
Per the SAG charter, consensus was defined as a general agreement
shared by all people in a group; it reflected a recommendation, option, or idea that all participants could support or abide by, or, at a
minimum, to which they did not object. Where consensus did not
exist, a vote was taken, and the votes of individual members were recorded along with a summary of the rationale for supportive and
dissenting views (see Appendix C).
The TWG and the SAG met monthly between June 2021 through
August 2022. In that period, the TWG met 14 times and the SAG
met a total of 15 times.
CPW and Keystone engaged approximately 3,400 participants
through 47 meetings and an online comment form in the summer of
2021. Meetings included 16 in-person public open houses throughout the state; 17 in-person Western Colorado geographic focus
groups; 10 virtual interest-based focus groups; 2 in-person Tribal
Colorado Wolf Restoration and Management Plan

consultations; and 2 virtual town halls. All meetings and the online
comment form provided the same informational materials (in the
form of video presentations or posters) as well as the same questions
posed to the public. The report of these meetings is summarized in
Keystone Policy Center (2021).
Using input from the TWG, the SAG, and the public meetings
and hearings, CPW staff developed a draft Plan. The draft Plan was
presented to the Commission and shared with the public in December 2022. The draft Plan was finalized and approved by the Commission on May 3, 2023.
Plan Goals
This plan fulfills the statutory requirements of CRS 33-2-105.8.
The primary goal of this Plan is:
To identify the steps needed to recover and maintain a viable,
self-sustaining wolf population in Colorado, while concurrently
working to minimize wolf-related conflicts with domestic animals,
other wildlife, and people.
Specifically, this Plan will:
• Outline and implement a methodology to restore, establish,
and manage a self-sustaining population of gray wolves using
the best scientific data available.
• Outline a methodology for determining when the gray wolf is
sustaining itself successfully and when to remove the gray
wolf from the state list of endangered or threatened species.
• Outline a program to assist owners of livestock in how to prevent and resolve conflicts between wolves and livestock, including compensation and conflict minimization programs.
Previous Planning Efforts for Wolves in Colorado
This current effort is not the first time that the State has developed
recommendations for wolf management. In 2004, the Colorado Division of Wildlife (CDOW, now CPW) director convened a 14-person working group to develop recommendations on how wolves that
naturally migrate into Colorado should be managed once the species
was federally delisted and management authority was returned to
the State (Colorado Wolf Management Working Group 2004).
When that group was convened, wolves were listed as federally endangered and therefore under the management authority of the
USFWS. A programmatic direction and a spectrum of management
activities was needed for the CDOW to address potential wolf-livestock conflicts, to maintain viable prey species populations, to address other management issues, and to gain the support of a public
with diverse interests. The final product of this effort was the 2004
Findings and Recommendations for Managing Wolves that Migrate
into Colorado (Colorado Wolf Management Working Group 2004).
The 2004 Findings and Recommendations did not consider any
aspect of reintroduction or recovery metrics. Rather, it simply stated
that wolves that migrate into the state will be managed with a “live
and let live approach.” If conflict with ungulate populations or livestock occurred, those problems would be managed using either lethal or non-lethal approaches. Importantly, the Findings and
Recommendations did not preempt Colorado Wildlife Commission
authority to formulate annual rules, set hunting regulations, or implement emergency actions in response to unexpected events or circumstances. It was, in essence, a suite of recommendations, nothing
more.
The Colorado Wolf Management Working Group’s recommenda3

�tions were adopted in their entirety by the Colorado Wildlife Commission at its May 2005 meeting and reaffirmed by the Colorado
Parks and Wildlife Commission in January 2016. Where appropriate, components of this original wolf planning effort are incorporated into this Plan. To the extent there is a conflict between this
Plan and the Working Group’s prior recommendations, this Plan
controls.
Summary of Historical Distribution of Wolves in Colorado
The gray wolf occupied most of the North American continent at
the time of European settlement. Its range was reduced dramatically
and by the 1880s wolves were extirpated from the east coast to the
central part of the United States. Gray wolves were still fairly common throughout most of the northwestern United States until the
early 1900s (Young and Goldman 1944).

Pressure from the livestock industry and a generalized public fear
led to the widespread persecution, and eventual near total extirpation of gray wolves from all western states. The gray wolf historically
inhabited all counties in Colorado and was extirpated from the state
in the mid-1940s (Armstrong et al., 2011). While CPW had received
reports of gray wolves in the state, it was not until 2004 when a dead
wolf was found on the side of Interstate 70, that there was hard evidence that this was the first wolf to have moved into Colorado from
the Northern Rockies in recent history. Several reports of wolf sightings in the State have been received and confirmed since 2004 (Table
1). In June 2021, CPW biologists confirmed the first documented
whelping in Colorado in approximately 80 years; wolves naturally
migrated into north central Colorado, paired, and gave birth to at
least six pups.

�Legal Status
Federal
The gray wolf has had a long and complex history with respect to
the federal status under the Endangered Species Act. A brief history
is provided below (USFWS 2020).
In 1973, the USFWS listed the subspecies, the Northern Rocky
Mountain (NRM) gray wolf (C. lupus irremotus) (38 FR 14678, June
4, 1973), pursuant to the Endangered Species Conservation Act of
1969. In 1974, the NRM gray wolf was listed under the Endangered
Species Act (ESA) (39 FR 1171, January 4, 1974). Due to questions
about the validity of wolf subspecies classification at the time and issues associated with the narrow geographic scope of each subspecies,
the USFWS published a rule reclassifying the gray wolf as endangered at the species level (C. lupus) throughout the contiguous 48

States (43 FR 9607, March 9, 1978).
This rule also provided assurance that this reclassification would
not alter the USFWS’s intention to focus recovery on each population as separate entities, including the Northern Rocky Mountains
(NRM) region, which includes Idaho, Montana, Wyoming, eastern
Oregon, and eastern Washington. Accordingly, a recovery plan was
developed for the NRM gray wolf population in 1980 (revised in
1987) (USFWS 1980, USFWS 1987).
The 1980 NRM wolf recovery plan’s objective was to re-establish
and maintain viable populations of the NRM wolf in its former
range where feasible (USFWS 1980), however it did not include recovery goals (i.e., delisting criteria).
The 1987 plan specified a recovery criterion of a minimum of 10
breeding pairs of wolves (defined as 2 wolves of adequate age capable
of producing offspring) for a minimum of 3 successive years in each

At the time of the drafting of this Plan, wolves are classified as "State Endangered" in Colorado. They may be downlisted to
threatened and eventually delisted as the population increases and expands in the state.

�of 3 distinct recovery areas including northwestern Montana, central
Idaho, and the Greater Yellowstone Ecosystem (GYE) (USFWS
1987). The 1987 recovery plan recommended that connectivity between these areas be encouraged. Critical reviews of the criteria in
the 1994 EIS and in a 2001/2002 peer review each resulted in minor
changes to the recovery criteria (USFWS 1994).
Wolves were reintroduced into Yellowstone National Park and
central Idaho in 1995 and 1996 as non-essential, experimental populations under Section 10(j) of the ESA (Fritts et al., 1997). Wolves in
the northwest Montana portion of the NRM were present when
wolves were reintroduced into Yellowstone National Park and central Idaho due to natural emigration from the Canadian population
to the north, thus were designated as endangered and were not part
of the non-essential, experimental population.
Wolves in most of the NRM were delisted by an Act of Congress
in 2011. Wolves in Wyoming were not included in 2011 law, but
were later delisted by USFWS in 2017. Thus, as of the date of this
Plan, wolves are not federally listed in Wyoming, or the rest of the
northern Rockies, but are listed as endangered elsewhere in the
western states including Colorado, most of Utah, California, and
western Oregon and western Washington.
The 2009 delisting rule for NRM wolves (which was subsequently
vacated and then reinstated — see USFWS 2020 at 69781) summarized the recovery criteria at that time as “thirty or more breeding
pairs (an adult male and an adult female that raise at least 2 pups
until December 31) comprising 300+ wolves in a metapopulation (a
population that exists as partially isolated sets of subpopulations)
with genetic exchange between subpopulations” (USFWS 1994).
Step-down recovery targets require Montana, Idaho, and Wyoming
to each maintain at least 10 breeding pairs and 100 wolves by managing for a safety margin of at least 15 breeding pairs and at least 150
wolves in mid-winter. Genetic exchange can be natural or, if necessary, agency managed. Federal recovery goals for this species have
never been identified for Colorado.
Until 2021, gray wolves in Colorado were listed as endangered
under the ESA and were under the management authority of the
USFWS. However, the USFWS published a Final Rule to delist the
species in all of the contiguous United States (USFWS 2020), effective January 4, 2021. Litigation challenging this decision was filed
and the delisting was vacated by a federal district court in California
(February 10, 2022), returning the species to its previous status (endangered in most of the lower 48, including Colorado, but not including the NRM). The district court decision has been appealed,
and is currently under review by the Ninth Circuit Court of Appeals.
Because of the uncertainty about the federal status of wolves, close
coordination with USFWS has occurred throughout the Plan development process and will necessarily continue through the implementation stages. The development and implementation of permits
and tools to provide regulatory assurances and management flexibility will be of high importance. To that end, at CPW’s request,
USFWS is undertaking the process to develop a 10(j) rule to address
management of wolves throughout Colorado, concurrent with the
development of this Plan. That is a separate, but related process. The
10(j) rule provides management flexibility that is a critical component to the success of this Plan and on which other components of
the Plan depend.

�Chapter 2:

Background and Key Elements for Conservation and Management
Wolf Management
Overall Management Philosophy

CPW will conserve and manage wolves in concert with the rest of our State’s native wildlife. Active
management will be required to address conflicts between wolves, people, livestock, and other wildlife
species. Conservation and management are not mutually exclusive concepts. Using a variety of management tools, our intention is to integrate and sustain wolves in suitable habitats within the complex biological, social, and economic landscapes of Colorado.
The term “management” refers to deliberate action or specific
conservation activities implemented by agencies or other entities to
assure the long-term presence of a wolf population and minimization of potential conflict or the resolution of conflict where and
when it develops. Agency actions are selected from a spectrum of
possibilities and are aimed at matching the appropriate management
tools to the situation. It is important to emphasize that management
is not synonymous with lethal control. Wolf population management will include the full range of tools from non-lethal to lethal
(when allowed under state and federal laws) and will incorporate
other agency functions such as public outreach, conservation education, law enforcement, landowner relations, and wolf conservation
actions. Non-lethal techniques can include education about changing livestock husbandry practices as well as attempts to modify wolf
or pack behavior through hazing.
This Plan is predicated on managing wolves in Colorado using
“impact-based” management within an adaptive management
framework that will allow CPW maximum flexibility to manage
wolves. An adaptive management framework incorporates monitoring and evaluation components in an ongoing effort that helps participants accumulate knowledge regarding the system of concern
(Walters 1986). The Colorado Wolf Management Working Group
Recommendations (2004) developed a list of fundamental assumptions related to what impact-based management meant at that time.
The SAG revisited those points and reaffirmed and supplemented
them. These were presented to CPW. CPW further expanded some
concepts to arrive at the following key tenets to define “impact-based” management which are foundational to this Plan.
Goals and Range of Impacts
• Goals of impact-based management include restoration of
wolves, minimization of conflicts, minimization of lethal take,
and building of trust across communities. Impact-based management should consider biological, ecological, social, agricultural, and economic dimensions of wolf management and
should recognize and consider diverse perspectives on these
topics.
• The presence of wolves in Colorado will have both positive
and negative impacts on humans, wildlife, other animals, and
local ecosystems.
• Impacts will vary in intensity and location based on a variety
of factors including wolf distribution, density, and behavior;
distribution, species, and density of livestock and wild ungulates; and land ownership patterns. Some impacts, such as the
possibility of increased tourism, may be viewed as negative or
Colorado Wolf Restoration and Management Plan

positive by different stakeholders and communities.
• Negative impacts could include, but are not limited to, the
following: depredation and harassment of livestock, herd
dogs, and guard animals; loss of pets and hobby animals;
concentration of wild ungulates on private lands possibly resulting in property damage; reduced ungulate hunting or
viewing opportunities; reduced hunting license sales resulting
in decreased revenue for wildlife management; and declines
in ungulate populations or in ungulate recruitment rates.
Some negative impacts may be low on a statewide scale but
can be acute on a local or individual scale, with social and
economic impacts for those affected.
• Positive impacts, where they occur, should be recognized and
fostered, and may include, but are not limited to: providing
complementary offtake of ungulates in management units
where they are overpopulated; dispersal of wild ungulates
that may result in habitat improvement due to less herbivory
on vegetative communities; selective removal of individual
diseased animals from herds; and social, economic or
non-monetary values, such as intrinsic value, existence value,
and other possible values for present and future generations.
Managing Impacts
• Wolves will be left wherever they are if they are not causing
problems.
• Monitoring of wolf populations, livestock conflict, wild ungulates, other wildlife species, hunter opportunity and success,
and human attitudes is an essential aspect of impact-based
management. Monitoring of economic and social dimensions
may also be conducted by sectors beyond CPW.
• If wolves establish in places where conflict is likely (e.g., in
proximity to livestock) proactive measures should be taken to
avoid problems using non-lethal methods. CPW — in partnership with Tribes in the case of conflicts arising on the sovereign lands of Tribal nations — will work with livestock
owners to investigate, assess the situation, and take appropriate action. Public and private organizations may also provide
support for conflict minimization in consultation with CPW.
• If wolves are creating conflict, manage to resolve the problem.
When negative impacts occur, they should be addressed on a
case-by-case basis using a combination of appropriate management tools, including education, non-lethal conflict mini7

�mization techniques, lethal take of wolves, and damage
payments. CPW will encourage use of proactive and reactive
non-lethal conflict minimization techniques as a first line of
defense, along with consideration of individual and community-level approaches. Lethal management should not generally be the initial response to conflicts, but there may be
certain conditions, discussed in Chapter 5, under which lethal removal of wolves may be used first to support effective
conflict management.
• Flexibility in the array of management tools is essential to accommodate changing circumstances over time and to allow
discretion for managers to consider biological and social context on the ground.
• Management must comply with federal and state regulations.
Use of management tools may be phased based on state listing status, balancing consistency across phases with specific
legal considerations. While wolves are federally listed, management tools must be used in accordance with the provisions of the ESA, including any 10(j) or other rules issued
pursuant to the ESA.
• Successful wildlife management includes both public and private lands, providing, where possible, consistency of management across land jurisdictions.
• As with any wildlife management program, the wolf management program will evolve through time; pragmatic, creative,
and adaptive management should be applied.
Engagement, Outreach and Capacity to Support Impact-Based Management
• CPW may, at its discretion, reconvene the SAG or TWG or
another advisory group(s). These groups may assist in finding resolution to unexpected or non-routine developments
that may occur.

Key Elements
A successful restoration program for wolves in Colorado requires
focus on several key elements for conservation and management.
CPW identified seven key elements that are considered most significant for the future of wolf conservation and management: 1) social
tolerance for wolves and economic impacts of their presence in the
state; 2) wolf recovery; 3) wolf management with respect to
wolf-livestock interactions; 4) wolf management with respect to
wolf-ungulate interactions; 5) wolf interactions with other wildlife
species; 6) wolves and human safety concerns; and 7) monitoring
and research.
Detail and background are provided for each of these key elements in the remainder of this chapter. Subsequent chapters take
each of these key issues and describe specific actions necessary to
implement a successful conservation program for this species.

Key Element 1: Social Tolerance
for Wolves and Economic Impacts
The gray wolf symbolizes the diversity of American thoughts, values, and opinions. From persecuted beast, to resourceful survivor, to
the top of the food chain, the gray wolf encapsulates the full spectrum of human emotion and interests (Bangs et al., 1998). As a result, wolf management is likely to remain as complex as it is
controversial (Bangs et al., 1998). Those involved in the Yellowstone
National Park and Idaho wolf reintroduction processes described
wolves as being the most contentious and scrutinized natural resource issue of their careers (Fritts et al., 1997).
Minimization of impacts to livestock owners, a required
component of the Plan, will rely on a strong partnership
between CPW and stakeholders.

• Education and outreach to foster shared learning and understanding of issues, management actions, and consequences
are key components of successful wolf management in Colorado. Effectiveness of education and outreach is impacted by
coordination and agreement on messaging. It is important to
provide livestock owners and their agents clarity on allowable
actions, legal parameters, and required permits or verifications.
• Sufficient funding and additional CPW staff should be made
available to implement all aspects of this Plan.

• A high degree of cooperation and coordination among management agencies within the state, among states, among state
and federal partners, and between the state and Tribes, is necessary to ensure that management actions and damage payments are efficient and timely. Cooperation and coordination
between management agencies and the private sector can be
beneficial to support conflict minimization.

Today, the social, cultural, and aesthetic values that Coloradans assign to gray wolves remain diverse but national and Colorado-based
survey results highlight generally positive attitudes toward wolves
(Pate et al., 1996; Meadow et al., 2005). However, these studies also
indicated that attitudes, concerns, and perceptions are often different
across stakeholder groups. As a result, social scientists and wolf experts emphasize the need for balanced and comprehensive public
outreach, stakeholder engagement, and education efforts. Specifically, the most valuable managers are those that consider the breadth
of stakeholder perspectives throughout the entire engagement process (Niemiec et al., 2021).
Colorado Parks and Wildlife

�Ultimately, successful stakeholder engagement processes are inclusive, equitable, efficient, collaborative, participatory in nature, and, in
the context of natural resource management, include biological/ecological as well as social goals (Blahna and Yonts-Shepard 1989; Lauber and Knuth 1999; Lord and Cheng 2006; Renn et al., 1995; Smith
and McDonough 2001; Susskind and Cruikshank 1987). Additional
best practices include engaging the public early and often in meaningful ways (so as to empower participants); incorporating public involvement opportunities throughout the entire planning process;
obtaining data from representative stakeholders using a variety of
methods; and using these data in decision making processes (Blahna
and Yonts-Shepard, 1989; Chase et al., 2004, Reed 2008). When
these aspects are meaningfully integrated into stakeholder engagement processes they help minimize conflict; reduce the likelihood
that stakeholders or groups are marginalized; legitimize planning
processes and outcomes; empower stakeholders; improve trust (especially when processes are transparent); promote social learning;
lead to higher quality decisions; and increase knowledge, awareness,
and overall support for decision making (Plummer et al., et al., 2017;
Okali et al., et al., 1994; Richards et al., et al., 2004; Serenari et al., et
al., 2018; Smith and McDonough 2001).
CPW, in collaboration with Keystone Policy Center, engaged
members of the public in a variety of ways as this Plan was developed. As the Plan is implemented, CPW and partner agencies,
NGOs, and other stakeholder groups will continue to use tools to
improve social tolerance. Ongoing social science research and potential future studies may explore the efficacy of CPW’s reintroduction efforts as well as other aspects associated with the human
dimension of wolf reintroduction.
The opportunity to view wolves potentially adds to the host
of viewable wildlife in Colorado.

dant wildlife, scenic mountains, national parks and wildlife refuges.
Wildlife viewing is among the top outdoor recreation activities for
visitors and residents alike. The opportunity to view wolves potentially adds to the host of viewable wildlife in the state. For example,
Hoag et al., (2022) examined the economic impact of wolves in the
Western United States and found that the financial benefits associated with having wolves on the landscape was many times greater
than what it cost to manage them. The authors used a “willingness to
pay” structure to examine these differences and, importantly, also
recognized that the costs and benefits are often unevenly distributed.
Additionally, they described the willingness to transfer some of the
economic benefits to the minority, particularly agricultural livestock
owners (who bear many of the costs) as a critical aspect to consider
when developing effective and equitable policies.
Negative impacts include economic losses from livestock depredation, and possibly decreased hunter opportunity due to shifts in ungulate distribution or a reduction in ungulate license numbers to
account for predation caused by wolves. If hunter opportunity decreases, CPW may see reduced license sales and associated income,
and local economies may be impacted from the loss of hunters. The
outfitting industry also may be negatively impacted if license sales
decrease. However, outfitters may also benefit from some clientele
wanting to view wolves. There may be an increased potential for
game damage from ungulates if wolves shift ungulate (primarily elk)
distribution from public to private lands. Agency capacity is likely to
be affected as well, with many currently assigned resources being reallocated to manage wolf issues. Without additional staff and funding, existing wildlife conservation priorities may receive less
attention over time.
Evaluating and calculating the economic benefit that a wolf restoration program has to the residents and visitors of Colorado, including who benefits and who pays, will be an important aspect to
developing support for this program.

Key Element 2: Wolf Recovery

A recovered wolf population in Colorado will bring both positive
and negative economic impacts. The economic impacts associated
with wolves are often difficult to predict but will be better understood through time as a sustainable wolf population is established
and wolf management in Colorado evolves (Hoag 2022).
Positive economic impacts may be realized from increased tourism in gateway communities. Colorado is well known for its abunColorado Wolf Restoration and Management Plan

The primary goal of this plan is to establish a self-sustaining population of wolves. Achieving this goal will be measured and compared against recovery objectives (Chapter 4). Recovery objectives
for downlisting and delisting a species need to be based on adequate
numbers of individuals which ensures that a self-sustaining population is reestablished. For the purposes of this Plan, a self-sustaining
population is one that maintains viability over time without continuous human intervention and conservation actions. For wolves, longterm persistence of a population in Colorado will depend on several
factors, including survival and recruitment rates, disease, prey availability, predation, proximity and connectivity (e.g., vonHoldt et al.,
2008) to other populations (outside and potentially within the state),
competing carnivore populations, the extent of conflicts with livestock production, and, perhaps most importantly, overall social tolerance by people.
The number of individual wolves needed to maintain the longterm viability of wolf populations is widely debated. In 1994, the U.S.
Fish and Wildlife Service (2008) concluded that 30 or more breeding
pairs comprising 300 or more wolves in a metapopulation (a population made up of partially isolated sets of subpopulations that exchange individuals and recolonize sites in which the species has
recently become extirpated) should have a high probability of longterm persistence. The geography for this analysis was the NRM
states of Montana, Idaho, and Wyoming. These states each manage a
minimum of 15 breeding pairs and 150 animals to meet minimum
federal delisting thresholds.

Key Element 3: Wolf Management
with Respect to Wolf-Livestock
Interactions
Another key element in a successful wolf reintroduction, conservation, and management effort focuses on wolf-livestock interactions. Wolves typically feed on wild ungulates. However, where
wolves and domestic livestock co-occur, conflicts can arise, particularly where both livestock and wolf densities are high. Minimization
of impacts to livestock owners, a required component of the Plan,
will rely on a strong partnership between CPW and stakeholders
working collectively to identify and implement best practices and
working solutions.

Modifying livestock management practices, particularly during calving or lambing seasons when animals are most
susceptible, may help reduce conflicts.

Some, but not all, livestock owners experience significant direct or
indirect economic impacts due to wolf presence or depredation
(Bangs et al., 1998). Wolf impacts to livestock, including direct mortality from wolf predation, and decreased weight gain, beget costs to
livestock owners. These costs are unevenly distributed and localized,
with some livestock owners suffering greater losses than others. Although wolf depredation is a small economic cost to the livestock industry as a whole, the impacts to individual livestock owners can be
substantial.
Domestic dogs used for livestock protection have also been
killed by wolves, particularly those guarding sheep from
predators in remote locations.

A synthesis of literature (Fritts and Carbyn 1995) gave insight into
minimum population size and area requirements for wolf conservation. The authors reviewed the scientific literature on minimum viable population size, examined case histories of wolf populations, and
queried biologists familiar with wolves. These authors were skeptical
of results from traditional population viability analyses because
those mathematical models were based on insufficient theoretical
models to account for the high resilience of small wolf populations.
In their survey of biologists about whether recovery goals in the
Northern Rocky Mountain Wolf Recovery Plan would equate to a
viable wolf population, 61 percent of respondents believed that 10
breeding pairs (about 100 wolves) met the minimum standard of a
viable population, whereas 70 percent agreed that three groups of 10
breeding pairs and 100 wolves in a metapopulation (about 300
wolves) for three consecutive years met the definition of viability
(Fritts and Carbyn 1995). Based on this assessment, Fritts and Carbyn (1995) concluded that 100 or more wolves might be needed to
maintain viability in isolation.
Low-density wolf populations can increase rapidly if they are protected and prey is abundant. Wolf populations in the greater Yellowstone area and Idaho areas exceeded all expectations for survival and
reproductions after the initial reintroductions took place (Bangs et
al., 1998). Within two years, populations became reestablished in
both areas, rather than the predicted three to five years, and pup
production and survival were high. However, as populations grew
and wolf densities increased, social interactions among packs intensified, causing intraspecific conflict and increased competition for
food. There is evidence that the leveling off of the wolf population in
Yellowstone was driven by a combination of disease and declining
prey resources. Sarcoptic mange and canine distemper both affected
the population from 2007 through 2009; distemper killed a high percentage of pups and mange killed off many breeding aged adults.
The population could not rebound to its size prior to the disease
outbreaks. While intraspecific mortality is important on a small
scale, prey availability and disease are likely much more important
on a relatively larger scale (Brandell et al., 2020, DeCandia et al.,
2021). These and other factors including disease eventually caused
populations to level off or decline (Keith 1983, Fuller 1989).
An underlying tenet of endangered species recovery is that populations need to be functionally connected so that genetic material
can be exchanged. Generally, the impact from the loss of genetic
variation may pose a conservation threat to any species by causing
reduced disease resistance, decreased reproductive rates, and other
problems. This can result in challenges to the long-term recovery of
populations regardless of other factors such as habitat and prey availability. Inbreeding depression has been suggested as the cause of reproductive problems (e.g., reduced sperm quality, decreased litter
size, reduced pup survival) and other problems (e.g., congenital
backbone deformities) noted in several small wolf populations
(Wayne and Vilà 2003, Liberg et al., 2005, Asa et al., 2007, Fredrickson et al., 2007, Räikkönen et al., 2009). Nevertheless, many existing
wolf populations have persisted for decades or centuries with low genetic diversity (Fritts and Carbyn 1995, Boitani 2003). Wolf populations are broadly considered to be more threatened by issues relating
to excessive human-caused mortality than by genetic concerns (Boitani 2003). Current wolf populations in the northern Rocky Mountain states are characterized by high levels of genetic variability and
substantial gene flow (Forbes and Boyd 1996, 1997, vonHoldt et al.,
2008, 2010, Hebblewhite et al., 2010), meaning that wolves arriving
in Colorado from these sources should be genetically healthy. The
continued migration of wolves from the established populations in
the NRM states (Table 1) will serve to supplement the genetic diversity of the population that is to be established in Colorado.

Colorado Parks and Wildlife

�Livestock Loss to Wolves
Addressing gray wolf-livestock conflicts is an essential part of this
Plan. The agricultural industry is a vital component of the Colorado
economy and provides important open space and habitats that support a wide variety of wildlife.
Depredations on cattle, sheep, other livestock, and guarding/herding dogs has occurred during the recovery of wolves in other states.
Despite significant increases in wolf populations, confirmed losses to
wolves have remained small to date relative to livestock numbers
(Bangs et al., 2005, USFWS 2008). Many factors influence depredation rates on livestock, including the proximity of livestock to wolf
territories, dens, and rendezvous sites; pack size; abundance of natural prey and livestock; amount and type of vegetative cover; time of
year; livestock husbandry methods in both the area of concern and
adjacent areas; the use of conflict minimization techniques, deterrents, and lethal take; pasture size; and proximity to roads, dwellings,
and other human presence (Mech et al., 1988, Fritts et al., 2003,
Treves et al., 2004, Bradley and Pletscher 2005). These factors also
make it difficult to predict where and when depredations by wolves
will occur.
Wolves don’t necessarily attack every time they encounter livestock, but at some point most wolf packs that regularly encounter
Colorado Wolf Restoration and Management Plan

livestock are more likely to depredate (Bangs and Shivik 2001,
Wydeven et al., et al., 2004). Some packs show increasingly frequent
depredation behavior, while others may do so once or twice a year,
every other year, or even less frequently (USFWS 2011).
Wolves tend to avoid humans, so people accompanying
livestock such as herders, range riders, or scouts, can reduce
encounters and help manage herds proactively.

Proactive conflict minimization techniques can help prevent conflict. Such tools often focus on modifying wolf, livestock, or human
behavior to minimize encounters. For example, physical or psychological barriers or scare tactics can be established to try to ward off
wolves and other predators. These include fladry (electrified-flagging), lights, and sound devices that rely on neophobia and can be
temporarily effective. These in and of themselves are not long-term
fixes but are meant to reduce conflict during periods of high vulnerability.
Modifying livestock management practices, particularly during
calving or lambing seasons when animals are most susceptible, may
help reduce conflicts. Removal of carcasses of livestock that have
died can also be useful, as carcasses can attract wolves and other
predators. When possible, adaptively managing grazing allotments,
when allowed by federal land managers, helps mitigate the risk of
depredation — for example, grazing near known wolf dens or rendezvous sites increases the vulnerability of livestock to depredation.
Thus, adjusting pasture rotations to avoid close proximity to dens
during denning or rendezvous sites can reduce conflict. Such livestock management practices entail costs in terms of time, labor, and
money that need to be considered if they are to be implemented by
livestock owners.
Although livestock (defined in CRS 33-2-105.8) losses from
wolves in Colorado are expected to occur on large ranches and public land grazing allotments, wolf-related losses may also occur on
smaller parcels in rural-residential areas. Many Coloradoans reside
in such areas, often located on elk and deer winter ranges or adjacent
to public land or private forest and rangelands. In addition to cattle
and sheep, other livestock including horses, goats, llamas, and donkeys, may be subject to depredation events.
Domestic dogs used for livestock protection have also been killed
by wolves, particularly those guarding sheep from predators in remote locations. When an adequate number of working dogs and
trained herders are present with livestock, animals appear to be less
at risk from wolves. Wolves also tend to avoid humans, so people accompanying livestock such as herders, range riders, or scouts, can
reduce encounters and help manage herds proactively. Increased
presence of range riders can also be effective in identifying timely
cattle and sheep depredations for confirmation and moving livestock
to areas where they are less vulnerable. However, this higher vigilance results in increased costs to livestock owners.

Sime et al., (2007) reported that among the 162 livestock owners
suffering confirmed wolf depredation in Montana between 1987 and
2006, 62 percent experienced a single incident, 20 percent experienced two incidents, and 17 percent experienced three or more incidents. A similar percentage (59 percent) of livestock owners with
wolf depredation in Wisconsin experienced a single incident between 1976 and 2000 (Treves et al., 2002). These affected livestock
owners represented 0.4 percent of the 7,424 full-time livestock owners in the state’s 19 counties. In Minnesota, the number of livestock
farms with verified wolf depredations on livestock was 0.3% annually during the period when there were 1,200-1,416 wolves (Ruid et
al., et al., 2009).
In the northern United States, wolf depredation on livestock occurs more frequently from March to October when livestock spend
more time under open-grazing conditions, calving is taking place,
and wolf litters are being raised (Fritts et al., 2003, Musiani et al.,
2005, Sime et al., 2007, Edge et al., 2011). Untended livestock, particularly young calves, appear to be more vulnerable, and the presence
of livestock carcasses left on a property may increase risk as well
(Fritts et al., 2003, Edge et al., 2011). Adult sheep appear to be taken
more frequently than lambs (Fritts et al., 2003). Depredations commonly involve multiple sheep per incident, whereas only 1-2 cattle
are usually killed per incident (Muhly and Musiani 2009). Depredations occur on both open grazing sites and inside fenced pastures.
Among northern Rocky Mountain and Great Lakes states, signifi11

�cant variation exists in the number of cattle and sheep killed by
wolves, and sometimes variation exists between years. Livestock
management differs among regions as well. Great Lakes states typically manage livestock in a more localized and accessible pasture
versus open range grazing in the western US, which is relatively inaccessible and poses greater challenges for livestock owners. Probable losses, in which officials are unable to verify the cause of death,
represent an additional loss that cannot be definitively attributed to
wolves. Additionally, it is challenging to locate all carcasses and notify authorities soon enough to obtain cause of death confirmation.
Rugged and vast terrain and vegetation where livestock graze, the
extent of carcass consumption by predators and scavengers, or carcass decomposition compound this difficulty.
Determination of a compensation ratio (a compensation mechanism that involves providing reimbursement for missing animals
based on confirmed depredations) continues to be debated. Identifying livestock mortality attributed to wolves varies considerably according to the characteristics of each grazing site, extent of rancher
supervision, and type, age, and number of livestock. Missing animal
ratios of 8:1 (without range riders) and 6.3:1 (with range riders) have
been reported for cattle in two studies conducted on large allotments
with forested and mountainous terrain (Oakleaf et al., 2003, Sommers et al., 2010). Oakleaf et al., (2003) suggested that a ratio of
about 2:1 was more realistic under less timbered or less rugged conditions. Detection ratios closer to 1:1 probably occur for many
smaller operations using private lands, where livestock are more
closely supervised. There has been critical review of these findings as
well (Hebblewhite 2011). In general, empirical support for determining compensation ratios is scarce, and studies often suffer from small
sample sizes, unmeasured/undetermined sources of livestock mortality, and unverified assumptions.
A detailed depredation compensation and conflict minimization
program is described in Chapter 6.
Livestock Losses to Other Causes
While the number of livestock killed by wolves in Idaho, Montana,
and Wyoming has generally increased over time as wolf numbers
have grown, these are small compared to losses caused by coyotes
(Canis latrans), mountain lions, bobcats (Lynx rufus), domestic dogs
(Canis familiaris), bears, foxes (Vulpes spp.), eagles, and other predators. Coyotes and other predators were responsible for almost all of
the losses in which the predator was identified (98.8 percent of the
cattle losses and 99.4 percent of the sheep losses) during 2004 and
2005; wolves were responsible for 1.8 percent and 0.6 percent of the
losses (NASS 2005). Most of these predators, such as coyotes, mountain lions, bobcats, black bears, and foxes, can be legally hunted or
are subject to lethal control if depredating. Wolf depredations are
also far less than combined non-predator losses (e.g., disease,
weather, and birthing problems) in Idaho, Montana, and Wyoming,
being less than 0.1 percent of these losses for cattle and 0.6 percent
for sheep (NASS 2005, 2006). Minor losses of other livestock species
by wolves in these states is also low. Nevertheless, managing to minimize and compensate for livestock losses due to wolves is a fundamental aspect of the Plan.
Management Tools
A variety of management tools will be implemented to meet restoration and management objectives for wolves in Colorado. Generally, the positive impacts from having wolves in Colorado will be
recognized without a prescriptive management practice. Negative
impacts, where they occur, will be addressed case-by-case.
This section describes many of the management tools that can be
implemented to assist livestock owners in reducing wolf-livestock
conflicts, including proactive deterrents, compensation programs for
12

wolf-related livestock losses and proactive methods, and various
hazing options and forms of limited lethal control.
Non-Lethal Methods
Non-lethal management tools are intended to avert or resolve a
wolf conflict without killing the wolf or wolves in question. In many
instances, non-lethal management tools effectively address the public or agency concern and are the most cost effective, least intrusive
method. If successful, non-lethal methods may also alleviate the
need for more intensive management actions in the future. Examples
of non-lethal techniques include changes in livestock husbandry
practices, range riders and herders, hazing of wolves, scare tactics,
and other attempts to modify wolf behavior. Techniques specifically
intended to modify wolf behaviors can be aversive or disruptive
(Bangs and Shivik 2001). Aversive stimuli cause discomfort or pain
to the wolf after it demonstrates certain behaviors. The repeated negative experience associated with certain behaviors may condition the
wolf not to repeat that behavior. Disruptive stimuli attempt to prevent or alter behaviors by disrupting the animal when it behaves in
undesirable ways. When disrupted by the stimuli, the animal is supposed to retreat. Examples are noise makers or siren devices triggered when a wolf gets too close to livestock. The National Wildlife
Research Center, the research arm of APHIS, has taken a lead in investigating the utility and effectiveness of these techniques to avert
wolf conflicts with livestock (Bangs and Shivik 2001, Breck et al.,
2002).
The role of certain husbandry practices, such as increasing supervision, pasture choice based on habitat features, and stocking rates of
different ages, have been shown to reduce livestock depredation risk
(Muhly et al., 2010). Though non-lethal measures and husbandry
practices may not have universal effectiveness and may not be feasible in some situations, they can be effective in reducing conflict in
some situations (Sime et al., 2007). It is important that managers and
livestock owners identify which measures are appropriate.
CPW has co-branded a “Hands on Resource Guide to Reduce
Depredations” (https://cpw.state.co.us/Documents/Wolves/Wolf_
Hands-on_Resource_Guide_Depredation_Prevention.pdf) that outlines many practices that livestock owners can implement and
deploy to minimize wolf depredations. Topics described include
Management Intensive Grazing, Livestock Guardian Dogs and Donkeys, Carcass Management, Range Riders and Herders, Fladry/Electrified Fladry, Scare Devices, High-risk Landscape Management, and
Herd Composition.
Lethal Removal to resolve livestock conflicts
When legally employed in Colorado, lethal removal of wolves in
response to depredation is considered a corrective action—its purpose is to stop presently-occurring damage by wolves in a localized
area, and not necessarily to address the potential of future depredations at a regional or statewide scale.
Lethal removal of wolves to resolve wolf-livestock conflict is controversial and heavily scrutinized by the public (Musiani et al., 2005,
Bangs et al., 2006, Bradley et al., 2015). It is also viewed by a majority
of the TWG and the SAG as being critically important to a successful wolf management program (Appendix B and C). In evaluating
the use of lethal control on a context-specific basis, CPW will consider the trade-offs among many competing factors including: the
ability to target depredating wolves, being efficient and effective with
conflict minimization, financial cost, wolf reproductive and recruitment success, wolf population size and listing status, impacts to livestock owners, and social/stakeholder interests when considering
lethal take options. As with all wolf management practices, lethal
control will only be implemented when in compliance with all state
and federal laws and regulations.
Colorado Parks and Wildlife

�Colorado Wolf Restoration and Management Plan

(Fritts and Carbyn 1995, Fritts et al., 2003, Bangs et al., 2006). The
concept of removing depredating wolves is believed to improve tolerance and reduce illegal take of wolves by the public (Bangs et al.,
1995). However, it’s unclear whether lethal removal in situations of
livestock depredations improves human tolerance for wolves. Research in Wisconsin suggested that lethal control measures in the
short-term were ineffective for increasing tolerance (Browne-Nuñez
et al., 2012) and may even increase illegal take (Chapron and Treves
2016). Additional research in Wisconsin, however, showed that illegal behavior toward wolves can be moderated with effective state
management programs which included lethal control of depredating
wolves (Olson et al., 2014). Hill et al., (2022) suggested that areas
with legal harvest of wolves by hunters and trappers (a topic different
than management removals) may benefit from reduced human-wolf
conflicts or alternatively that areas with legal harvest have less potential for management removals (e.g., less livestock depredation). Bearing all this in mind, continued outreach, education, and effective
management will be critical to increasing tolerance of wolves and
ensuring long-term conservation of wolves in Colorado. Wolf management in Colorado is addressed in Chapter 5.

Key Element 4: Wolf Management
with Respect to Wolf-Ungulate
Interactions
Colorado has populations of elk, mule deer (Odocoileus hemionus), white-tailed deer (Odocoileus virginianus), pronghorn (Antilocapra americana), bighorn sheep (Ovis canadensis), mountain goats
(Oreamnos americanus), and moose (Alces alces). These ungulates
have high social, biological, economic, and recreational value in Colorado, and are also an important food source for native carnivores.
Revenue generated from hunting is important to rural communities,
and license sales provide funding for wildlife and conservation activities implemented by CPW. Consequently, managers are presented
with the challenge of maintaining ungulate populations that will sustain both carnivore populations and recreational hunting opportunities, while also minimizing agricultural damage and other
wildlife-human conflicts. (See: https://cpw.state.co.us/thingstodo/
Pages/HerdManagementPlans.aspx)
If wolves persist in high enough numbers for enough time,
they might be expected to contribute to local reductions of
some ungulate herds or changes in distribution of those herds.

Protection of livestock by allowing the lethal removal of wolves
caught in the act of attacking livestock is a tool to resolve wolf-livestock conflict (Bangs et al., 2006). This type of take is thought to empower livestock owners to protect livestock (Sime et al., 2007) and
immediately targets the offending animal(s) while eliminating the
need for further control by agencies (Bangs et al., 2006).
A central requirement of this Plan is that it utilize the best scientific data available. Unfortunately, the best data on the effectiveness
of lethal removal are inconclusive or even contradictory. Thus, the
results can be difficult to interpret. Rather than being a controlled
design using random assignment of treatment and controls, they are
instead observational in nature. In these circumstances, extrapolation of results from localized packs to a range wide population is
problematic and should be avoided or done with caution.
That said, the general understanding is that the effectiveness of lethal removal is short-term, often lasting only for the current grazing
season (Bradley 2004, Musiani et al., 2005). Lethal control has been
implemented while still accommodating a growing and self-sustaining wolf population. In Montana, despite the lethal removal of 254
wolves from 1987 to 2006, the population continued to grow and expand its distribution (Sime et al., 2007). The combination of non-lethal and lethal methods (which included the ability to lethally
remove wolves caught in the act of attacking livestock) was thought
to have kept depredations at a lower level than was originally predicted in Montana (Sime et al., 2007).
Wielgus and Peebles (2014) found a positive relationship between
lethal control at a statewide scale and subsequent-year depredations,
suggesting that lethal control actually had the opposite of its intended effect. Others have refuted these findings (Poudyal et al.,
2016, Kompaniyets and Evans 2017). Similarly, Harper et al., (2008)
conducted a long-term, statewide analysis of lethal management of
wolves in Minnesota. Their results suggested that killing a high
number of wolves did not result in fewer depredations the following
year (Harper et al., 2008). A study of the NRM found that lethal removal was effective at reducing further depredations, though the effectiveness was strongly related to the number of wolves removed.
Entire pack removal was more effective than partial pack removal
(Bradley et al., 2015). Partial pack removal reduced subsequent depredations by 29 percent, while full pack removal reduced subsequent
depredations by 79 percent over a span of five years (Bradley et al.,
2015).
While lethal removal has been observed in some cases to reduce
subsequent depredation at the pack level over a short period, there is
less evidence to support long-term reduction. Musiani et al., (2005)
observed development of a cycle in which new wolves re-colonized
and caused new depredations, leading to additional removals of
wolves. The size of the pack of remaining wolves following lethal removal was the best predictor of recurring depredations with larger
remaining packs having a higher probability of recurring depredation than smaller packs.
In situations of lethal removal of breeder wolves, the probability of
pack dissolution is increased (Brainerd et al., 2008, Borg et al., 2015),
though the dissolution does not appear to have significant effects on
overall population dynamics due to strong compensatory mechanisms (Borg et al., 2015). Lethal removal of solitary individuals or
territorial pairs in situations of chronic wolf-livestock conflict would
be expected to have fewer effects on overall wolf conservation
(Brainerd et al., 2008). This study also suggested that impacts to
overall wolf populations are reduced when lethal removal is conducted on reproductive packs when pups are ≥6 months old and
packs contain ≥6 members (including ≥3 adult-sized wolves) (Brainerd et al., 2008).
Human tolerance toward wolves has long been recognized as an
important factor in recovery and persistence of wolf populations

The effect of wolves on ungulate abundance and management decisions affecting ungulate hunting opportunities at a large scale is
13

�complex and sweeping generalizations are difficult. There is the potential for wolves, in concert with other predators and factors, to locally reduce ungulate abundance. There are a variety of factors that
contribute to regional herd sizes such as Herd Management Plan
(HMP) population objectives, forage quality and quantity, drought,
winter severity, habitat loss or degradation, competition with other
grazers, disease, vehicle collisions, other predators, and hunter harvest. Therefore, it is challenging to unequivocally determine a single
factor driving herd performance.
Herd reductions could have both positive and negative impacts on
local habitats and social tolerances of wolves and ungulates. Ultimately, if wolves persist in high enough numbers for enough time,
they might be expected to contribute to local reductions of some ungulate herds or changes in distribution of those herds, both of which
could have positive and negative impacts.
Predator-Prey Interactions
Colorado currently sustains populations of several medium and
large carnivores that are known to prey upon ungulates, including
black bear, mountain lion, coyote, and bobcat. The restoration of
wolves to the state will undoubtedly add complexity to ungulate
population dynamics. However, the effects of wolves on native ungulate populations are difficult to predict because of the complex multiple-prey/multiple-predator system observed in Colorado. A large
body of literature suggests a complex suite of abiotic, bottom-up, and
top-down forces including hunter harvest, predation, primary productivity, and climatic conditions that may be limiting or regulating
factors of ungulate population dynamics (Crête 1999, Vucetich et al.,
2005, White and Garrott 2005a, Wright et al., 2006, Melis et al., 2009,
Griffin et al., 2011, Middleton 2012, Johnson et al., 2013, Middleton
et al., 2013a). Consequently, the relative effects of wolf predation in
Colorado are likely to be situation-dependent and influenced by additional localized or regional factors.
Ungulates are primary prey for wolves. The best available scientific information suggests that, generally, wolves preferentially prey
on elk when present, but will also prey on deer and moose (Smith et
al., 2010, Orning et al., 2021). Significant effort, funding, and time
has been spent to enhance elk, deer, and moose populations in Colorado; therefore, understanding the interactions between wolves and
these ungulates will be important for future management of both
predator and prey. Predation on mountain goats, and bighorn sheep
is not anticipated to be significant. Non-native feral animals, such as
wild horses (Equus ferus), could also be preyed upon by wolves in
western Colorado.
Predators like the gray wolf may select prey compromised by diseases, which could prove useful in reducing disease prevalence in
ungulate populations, primarily when pathogens are directly transmitted among hosts. The strength of a potential disease reduction
depends on numerous factors, including specific disease etiology, the
strength of selection for infectious individuals, and overall predation
rates (Brandell et al., 2022). It is difficult to predict whether wolves
will have a measurable effect on chronic wasting disease (CWD) in
Colorado, where CWD is already well-established in the environment and in mule deer, white-tailed deer, elk, and moose.
The impacts of wolves on prey abundance have been, and continue to be, widely debated (see Boutin 1992). Some common conclusions on this topic have been drawn. A number of studies indicate
that wolf predation can limit ungulate abundance (Bergerud and
Snider 1988, Larsen et al., 1989, Ballard et al., 1990, Skogland 1991,
Gasaway et al., 1992, Dale et al., 1994, Messier 1994, Van Ballenberghe and Ballard 1994, Adams et al., 1996, Boertje et al., 1996, National Research Council 1997, Hayes and Harestad 2000,
Hebblewhite et al., 2002, 2006, Hayes et al., 2003, Mech and Peterson
2003, White and Garrott 2005b, Hebblewhite and Merrill 2007).
14

Population-level effects result primarily through predation on
young-of-the-year and are frequently compounded when occurring
in combination with other predators (e.g., bears) (Larsen et al., 1989,
Barber-Meyer et al., 2008, Boertje et al., 2009).
Several studies have detected little or no effect from wolves on ungulate abundance (Thompson and Peterson 1988, Bangs et al., 1989,
Peterson et al., 1998; see Mech and Peterson 2003; DelGiudice et al.,
2006, 2009). Mech and Peterson (2003) suggested three reasons why
researchers have failed to reach agreement regarding the significance
of wolf predation on the dynamics of prey populations. These are (1)
each predator-prey system has unique ecological conditions, (2)
wolf-prey systems are inherently complex, and (3) population data
for wolves and their prey are imprecise and predation rates are variable.
Some research has shown that predation may influence prey populations through changes in in situ recruitment (Nichols and Pollock
1990), adult mortality, or a combination of both (Gasaway et al.,
1992, Ballard et al., 1997, Kunkel and Pletscher 1999, National Research Council 1997, Ballard et al., 2001). Increased adult female
mortality from other sources, such as hunter harvest or elevated
overwinter mortality, may create conditions in which predation can
limit ungulate abundance or slow population growth (Kunkel and
Pletscher 1999). Some biologists reported that habitat and climate
influenced deer abundance more strongly than wolf predation (Wisconsin Department of Natural Resources 1999).
Prey selection and kill rate by wolves varies greatly depending on
many factors including pack size; snow conditions; the diversity,
density, and vulnerability of prey; and degree of consumption of the
carcasses (Kunkel 1997). The rates at which wolves kill and consume
prey are highly variable with respect to time of year and species
taken. Snow depth and wolf density best explained the annual variation in kill rate in northwestern Montana (Kunkel 1997). Based on
studies with the most similar species and diversity of prey (Carbyn
1983, Keith 1983, Boyce 1990, Vales and Peek 1990, Mack and Singer
1992), wolves were projected to kill about 16.5 ungulates per wolf
per year in Idaho (USFWS 1994). Kill rates vary on pack size and
weather conditions, but usually range from 3-16 days between kills.
On an annual basis in Yellowstone National Park an individual wolf
eats approximately 18-22 elk (Smith et al., 2020).
Regardless of the effects wolves have on ungulate population dynamics and abundance, some stakeholders may expect CPW to reduce antlerless licenses due to these real or perceived effects. CPW
HMP (herd management plan) population objectives and license
quotas are approved through a Commission process. CPW ungulate
population monitoring will be critical to inform management decisions. CPW has a unique opportunity to gain understanding of the
predator-prey interactions and the subsequent effects on ecological
processes in Colorado following reintroduction of wolves. Monitoring of prey distributions and population dynamics pre-wolf restoration (at least 2-3 years) and post-wolf restoration will provide a
valuable comparison to address measurable responses. Current investigations addressing ungulate distribution and population dynamics are ongoing and will be informative as wolves become
established in the future.
Vegetation effects
The removal or restoration of apex predators can influence behavior, abundance, and population dynamics of prey species. This can
result in changes to vegetative communities (Schmitz et al., 2006),
which then influence other wildlife or ecosystem processes (Ripple
et al., 2010). This is often referred to as a trophic cascade (Hairston
et al., 1960, Beschta and Ripple 2009). To reduce predation risk,
some prey will alter their behavior, movements, diet, and habitat use
(Schmitz et al., 1997, Laundré et al., 2001, Hernández and Laundré
Colorado Parks and Wildlife

�Colorado Wolf Restoration and Management Plan

where ungulate populations are carefully managed through hunting.
Ungulate Management
In Colorado, Ungulate management is regulated by several processes, all of which are approved by the Commission. Herd Management Plans (HMP) establish 10-year objectives for each ungulate
species and herd. This is accomplished through a public process,
using the best available scientific information on populations, habitat
conditions, and public input. Big Game Season Structure (BGSS)
policies define a 5-year framework for achieving HMP objectives
through a variety of hunting opportunities and seasons. Finally, annual harvest objectives and the resulting license recommendations
for all hunts are designed to achieve the management objectives approved in the HMP. Hunting license recommendations are based on
a regular evaluation of ungulate harvest, age and sex classification
data, population estimates, hunter distribution, and social considerations for each ungulate
herd in Colorado. Antlerless harvest is the primary
population management
tool for ungulate populations. When herds are
below population objective ranges, the number
of antlerless licenses is reduced or eliminated to
allow herds to increase.
When herds are above
population objective
ranges, antlerless licenses
are increased. Colorado

for an economically significant and diverse
amount of big game-related wildlife recreation.
Big game hunting in Colorado is highly regulated; carefully set limited license quotas manage
all female harvests, which is the primary tool for population management.
Ungulate management in Colorado attempts to balance many factors, including desired population size, habitat availability and condition, landowner tolerance, hunter opportunity, and environmental
factors influence populations. Ungulate populations are managed
considering both socio-economic and ecological factors. The scale
with which CPW manages ungulate populations is not intended to
mitigate the impacts of a single limiting factor such as wolf predation, mountain lion predation, or other mortality sources in and of
themselves. Instead, ungulate populations are managed by taking
into consideration a variety of factors to manage ungulate herds to
their HMP objectives.
Maintaining robust ungulate populations will remain a priority for
CPW, to provide Coloradans and visitors with opportunities for
hunting and wildlife watching, as well as provide adequate prey for
wolves. Ungulate harvest objectives in Colorado may need to be adjusted over time as a result of wolves on the landscape, which will
impact hunting opportunities for resident and non-resident hunters,
as well as businesses that rely on hunting, such as Outfitters. Additional regulatory restrictions, such as shortened hunting seasons to
reduce hunter success rates, may need to be considered in some
areas where wolves become established. Management prescriptions
should be based on the most up-to-date science and data available to

2005, Laundré et al., 2010). This could lead to changes in vegetative
communities and subsequent trophic cascades (Ripple and Beschta
2004, Fortin et al., 2005).
While the role of wolves shaping trophic cascades has been widely
reported and popularized, many of the conclusions that have been
reached on the topic are equivocal (Garrott et al., 2005, Brice et al.,
2022). For example, Hebblewhite and Smith (2010) indicated that
willow in Yellowstone National Park appeared to have benefited
from reduced browsing pressure from elk, but other woody browse
species were not showing signs of recovery following wolf reintroduction. Kauffman et al., (2010) found that recovery of aspen in Yellowstone National Park was not occurring even in sites where elk
were more vulnerable to predation, suggesting behavioral changes in
elk alone were not sufficient to benefit aspen recovery. Middleton et
al., (2013b) found further support that elk behavior is not heavily influenced by wolf predation. When wolves were in close proximity to
elk (&lt; 1 km), elk increased movement rates, shifted distributions,
and increased vigilance; however, elk were only this close to wolves
once every 9 days. This led to minimal changes in elk behavior overall, which likely limited the strength of any trophic cascades observed. Additionally, physical factors (e.g., snow depth, soil
moisture) were equally important in determining willow and aspen
growth in relation to browsing by elk (Tercek et al., 2010, Kauffman
et al., 2010). In a decade-long study in Yellowstone National Park,
Marshall et al., (2013) found that the reduction in herbivore browsing attributable to reduced elk populations did not correlate with the
recovery of riparian vegetation. Rather, to restore riparian vegetation
and structure, ungulate browsing would have to be completely
stopped along with restoration of hydrological conditions (e.g., reconnecting historic floodplain and stream channels) (Marshall et al.,
2013). The authors concluded that the effects of predation from a
top carnivore alone on ungulate behavior and population size is unlikely to reverse the decades-long changes that have occurred in riparian systems due to over browsing by ungulates.
It is also important to consider that while there is evidence that
trophic cascades and other ecosystem-level responses have occurred
following the recolonization of wolves, they have largely been observed in national parks or other protected areas where elk densities
were high and not managed with hunting. Outside of protected
areas, other factors may play a relatively larger role in shaping vegetative communities. Ungulate density, behavior and habitat use, and
ultimately ecosystem structure and composition are important factors to consider. Land management activities, such as fire suppression and timber harvest, influence vegetation structure and
composition (Parsons and DeBenedetti 1979, Lindenmayer and
Franklin 2002). Cattle grazing also influences vegetation structure
and composition and may alter elk behavior and movements (Averett et al., 2017; Stewart et al., 2002). Hunting (Conner et al., 2001,
Vieira et al., 2003, Proffitt et al., 2010, Cleveland et al., 2012) and disturbance from motorized vehicles (Johnson et al., 2000, Rowland et
al., 2000, Naylor et al., 2009, Coe et al., 2011) can also have a large effect on behavior, movements, habitat use, densities, and distribution
of elk. Further, while elk have shown changes in movements and behavior in response to both human hunting and wolves in the Greater
Yellowstone Area, the observed responses to human hunting were
greater than to wolves (Proffitt et al., 2009), suggesting that elk may
already have altered their behavior and habitat use outside of protected areas. Finally, additional factors, including climate and habitat
productivity may directly affect ecosystems (Oksanen et al., 1981,
Crête 1999) and the degree to which wolves influence ecosystem
structure and function (Rooney and Anderson 2009). Consequently,
it is unlikely that the magnitude of ecosystem changes observed in
some protected areas will occur in the more managed and multiple-use landscapes of Colorado, where livestock grazing occurs, and

15

�Scientists have noted (Creel and Winnie 2005, Mao et al., 2005,
Proffitt et al., 2009), that wolves may cause some redistribution of
ungulates, which could make these species less vulnerable to hunter
harvest. Managers in Colorado are increasingly concerned with elk
refuging on private lands or otherwise inaccessible areas, where ungulate harvest management is no longer a viable option. Furthermore, as has been reported in other western states where wolves are
present, there is concern that these refuging issues may be exacerbated following wolf reintroduction, as elk seek lower predation risk
environments closer to human development. However, these potential impacts would likely be restricted to the relatively few areas occupied by packs during the early to middle stages of reintroduction.
Larger wolf populations could be expected to have a greater effect on
ungulate distribution, abundance, and hunting opportunity. However, such impacts may become increasingly difficult to predict or
measure.

Status of Elk, Deer, and Moose
Populations in Colorado
Elk Summary
Colorado’s statewide elk population peaked in 2001 and as of 2021
was estimated at 309,000 after hunting season. In 2004, antlerless license numbers were at their highest which helped reduce elk populations to Herd Management Plan population objectives. Since 2004,
the statewide total elk population estimate has increased as a result
of CPW reducing antlerless and either-sex elk licenses every subsequent year.
The sum of Colorado’s post-hunt HMP population objective
ranges for elk statewide is 252,000-306,000 for all 42 elk herds combined. These data indicate that Colorado’s elk population is over objective. However, it is important to point out that the sum of
statewide objective ranges is partially based on historic and outdated
HMPs. HMPs written before 2006 were based on previous populaMaintaining robust ungulate populations will remain a priority for CPW, to provide Coloradans and visitors with opportunities for hunting and wildlife watching, as well as
providing adequate prey for wolves.

tion models that underestimated elk numbers. As CPW updates
plans, we expect population objectives to change, which will align
better with current population estimates. Because the hunting season and license numbers are designed to use antlerless harvests to
bring elk populations to herd objectives, future reductions in antlerless licenses are anticipated as more elk populations reach objectives
or population objectives increase. CPW has reduced antlerless and
either-sex elk licenses significantly as herds reach or approach population objectives or when calf ratios and juvenile recruitment into
the population decline.
As CPW has intentionally reduced elk populations to achieve
population objectives, hunters, outfitters, and even some private
landowners have increasingly expressed concern that in some areas
elk populations are below desired levels. Nonetheless, public opinion
on the desired number of elk in Colorado varies. CPW gives serious
consideration to changing population objectives in herds as HMPs
are updated. It tries to balance the public interests of landowners,
local communities, public land management agencies, and hunters.
Long-term experience with balancing these interests has informed
CPW on the upper and lower social thresholds for elk population
size in many herds, which greatly benefits managers in herd management planning efforts.
In 2021, during post-hunt winter herd inventories, CPW staff
used helicopter surveys to classify 108,000 elk (35 percent of the estimated total population). During these surveys over the past 20 years,
CPW has documented declining calf/cow ratios in the southern half
of the state. Ratios of calves to 100 cows are an index of annual calf
production and survival to mid-winter, which is an indicator of the
“fitness” or productivity of the herd. Elk research and continued
management changes are necessary since calf production remains
low in many herds. Low calf ratios reduce the number of elk licenses
CPW can issue and still maintain stable populations. Northern Colorado historically has had higher calf ratios by about 10 calves per
100 cows and have remained more stable than southern Colorado.
All rifle licenses for cow elk are limited (i.e., have a set quota). The
statewide total allocation for antlerless elk licenses was 64,500 in
2022, which is less than half of what it was at its peak in 2004 of
132,500 when CPW was actively trying to reduce populations. Antlerless elk license reductions are the result of a combination of herds
achieving HMP population objectives through antlerless harvest,
low calf/cow ratios reducing population productivity, and increases
in HMP population objective ranges. This trend of reducing elk licenses, and therefore hunting opportunity, is expected to continue,
which has long-term implications socially, culturally, and economically both for Colorado communities and CPW. The sale of elk licenses currently accounts for approximately 46 percent of CPW’s
hunting and fishing license revenue.
Demand for Colorado limited elk licenses far exceeds quotas; in
2022 approximately 238,000 hunters applied for 123,100 limited elk
licenses. Elk hunters from all over the country are interested in hunting here.
CPW has several important elk research projects underway to determine causes of calf ratio declines. For publications and more information, please visit: https://cpw.state.co.us/learn/Pages/

Deer Summary
Mule deer populations in western Colorado have declined precipitously since the 1970s. CPW and the public have concerns over mule
deer declines in the largest herds of western Colorado. Mule deer
populations face increasing threats, including loss of habitat from
development, highways bisecting migration routes, human recreational disturbance, fire suppression, drought, competition from elk,
disease, invasive weeds replacing preferred forage plants, and preda16

tion. Anything that lowers adult female survival will likely result in
further declines in any mule deer populations.
Colorado’s statewide deer population declined from roughly
600,000 deer in 2006 to an estimated 416,000 post-hunt 2021. The
statewide deer population has been more stable recently, averaging
420,000 over the last 11 years. The sum of all herd population estimates is still far below the sum of individual HMP population objective ranges of 438,000-520,000 for all 54 deer herds combined.
Declines in deer populations are primarily in the largest, westernmost mule deer herds in the state. In 2021, 26 of 54 (48 percent) deer
data analysis units were within their population objective ranges and
18 of 54 herds (33 percent) were below their population objective
ranges. There is on-going interest from various constituents to increase mule deer populations; however, for many deer herds, population management is largely dictated by herd productivity and
performance, winter severity, and Chronic Wasting Disease (CWD)
prevalence.

Many deer herds in the central and
northern mountains as well as the
eastern plains are performing well.

Diverse habitat types and annual precipitation around the state
create considerable geographic variability in population performance. Many deer herds in the central and northern mountains as
well as the eastern plains are performing well, and population sizes
and license numbers in those areas are increasing.
In 2014, CPW completed the West Slope Mule Deer Strategy,
which guides management decisions to help rebuild our mule deer
populations. The Strategy states: Together with the public and stakeholders, CPW will work to stabilize, sustain, and increase mule deer
populations in Western Colorado and, in turn, increase hunting and
wildlife-related recreational opportunities. The West Slope Mule
Deer Strategy outlined 7 strategic priorities to address the many
threats facing mule deer populations. To learn more, see Colorado’s
Mule Deer Story and Colorado’s West Slope Mule Deer Strategy at:
https://cpw.state.co.us/learn/Pages/CO-WestSlopeMuleDeerStrategySummit.aspx
Colorado Wolf Restoration and Management Plan

Deer hunting is managed using a license quota system (totally
limited licenses). Demand for deer hunting in Colorado is high. In
2022, approximately 218,000 hunters applied for 102,000 Colorado
deer licenses. CPW has substantially reduced doe harvest in western
Colorado because many herds are below population objective
ranges. This reduction in doe harvest is intended to allow herds to
increase to management objectives. CPW has recently been increasing buck deer licenses in West-slope herds to manage towards sex
ratio objectives; however, total license numbers are still below mid2000 levels as a result of the severe winter of 2007/2008, and subsequent population performance constraints. The sale of deer licenses
currently accounts for approximately 9 percent of CPW’s hunting
and fishing license revenue.
CPW intensively monitors over 1,000 radio-collared mule deer
annually to estimate annual adult doe survival and winter fawn survival in five Intensive Mule Deer Monitoring Areas. These herds include D-7 White River, D-9 Middle Park, D-16 Cripple Creek/Upper
Arkansas River, D-19 Uncompahgre Plateau, and the Gunnison
Basin (includes D-21, D-22, and D-25). We also monitor buck survival in D-7 and D-9. Survival rates from these herds are used in
deer population models for the rest of the herds west of I-25. These
monitoring areas also provide information on seasonal use, migration and movement, and cause-specific mortality.
CPW conducts winter herd classification surveys, primarily with
helicopters, to estimate the sex ratios of males to 100 females and the
age ratios of young to 100 females. During winter herd surveys in
2021, CPW staff classified 78,000 deer (19 percent of the estimated
population). Ratios of fawns to 100 does are an index of annual fawn
production and survival to December, which is an indicator of the
productivity or “fitness” of an individual herd. Since the early 1970s
in Colorado, the ratio of mule deer fawns to 100 does has declined
(Bishop et al., 2005, Bergman et al., 2011).
Chronic Wasting Disease in deer is a concern for CPW. From the
early 2000s to the present, CWD prevalence has increased significantly in some herds. In January 2019, the Commission approved
the Chronic Wasting Disease Response Plan. The plan will guide future management decisions that strive to reduce or keep CWD at
low levels. In 2017, CPW initiated a fifteen-year mandatory sampling program to estimate CWD prevalence in deer statewide. For
more information and for prevalence estimates, visit: https://cpw.

Moose Summary
CPW transplanted moose into Colorado to create hunting and
wildlife viewing opportunities. The first transplant occurred in
1978–1979 into North Park. Other major transplants included the
Laramie River drainage (1987), Upper Rio Grande River (1990),
Grand Mesa (2000), and White River drainage (2010). As a result of
these efforts, moose have become an important big game hunting
and popular watchable wildlife species in Colorado. Moose populations are increasing, and they continue to pioneer into new habitats
on their own. The statewide 2021 winter moose population estimate
is 3,500.
Demand for moose hunting far exceeds allocation; 54,000 individuals applied for a moose license in 2022 for a total of 592 limited
moose licenses. CPW manages moose hunting in 74 Game Management Units (GMUs), up from 39 GMUs in 2013. CPW has been increasing cow moose hunting licenses to manage moose populations
toward objectives, to keep moose populations within the ecological
carrying capacity, and to address moose conflicts in some areas. Colorado is fortunate that moose populations continue to do well be17

Key Element 5: Wolf Interactions
with Other Wildlife Species
The fifth key element in successful reintroduction and management of wolves involves wolf interactions with other wildlife species.
As with ungulates, gray wolves in North America and elsewhere
have co-existed for millennia with a variety of other carnivore species in many different habitats. In Colorado, wolves will share habitats occupied by a number of other carnivores, including mountain
lions, coyotes, black bears, bobcats, Canada lynx (L. canadensis), red
foxes (Vulpes vulpes), river otters (Lontra canadensis), mink (Neovison vison), martens (Martes americana), weasels (Mustela spp.),
striped skunks (Mephitis mephitis), American badgers (Taxidea
taxus), and raccoons (Procyon lotor). Direct and indirect interactions
will occur as wolves begin to reoccupy portions of their historical
range in Colorado and reestablish packs.
How diverse carnivores interact with wolves varies depending on
the extent of dietary overlap, habitat, environmental conditions, and
other factors. These interactions can be positive or negative. They
can also change throughout the year and at the various stages of wolf
recovery. Information regarding the interactions between other carnivores and wolves is primarily observational and therefore subject
to interpretation when attempting to make predictions at the population or community level. Because wolves are wide-ranging and
many carnivores are secretive in nature, collecting data on these interactions is difficult. Observations to date suggest that wolves can
reduce, or, in rare cases, eliminate certain carnivores (such as coyotes) locally, but no evidence of long-term spatial partitioning of resources within an area has yet been detected (Ballard et al., 2003).
Wolf-related reductions in coyote abundance may result in population changes among other medium-sized and small carnivores, either directly through reduced predation by coyotes or indirectly
through adjustments in prey availability. For example, reduced interference competition with coyotes may increase the abundance of red
foxes (Mech and Boitani 2003). Similarly, wolf related reductions in
coyotes or exclusion of coyotes from certain areas may result in increased survival for some prey species consumed by coyotes (e.g.,
pronghorn; Berger et al., 2008, Berger and Conner 2008, Barnowe-Meyer et al., 2010).
The effects of wolves on mountain lion populations are variable.
Research in Yellowstone National Park did not find a population effect of wolves on mountain lions (Ruth et al., 2019). Mountain lions
18

may display spatial or temporal avoidance of wolves, such as moving
up in elevation. Wolves might displace mountain lions from their
kills, and mountain lions may increase their kill rates to account for
this loss.
It is doubtful that wolves will greatly affect the overall numbers or
distribution of other carnivore species in Colorado. However, the
presence of wolves likely will change the local distributions and behaviors of some carnivores as they attempt to avoid direct interactions with wolves or as they respond to changes in food availability.
Such changes could favor some carnivore species over others. CPW
has considered interactions of wolves with other wildlife and determined it is desirable to improve our understanding of the baseline
conditions and relative abundances of other carnivores that wolves
are considered most likely to interact with or affect. CPW has estimated density of black bears at small spatial extents across the state,
as well as density of mountain lions at larger spatial extents. Bobcat
estimates may be available as soon as Fall 2023. There is not, at this
time, an anticipated effect of wolves on any carnivores that will require a need for management intervention.
Monitoring of wildlife communities (with an emphasis on state
and federally listed species and species of concern) is needed in areas
occupied by wolf populations to determine potential direct and indirect effects on species population trends, habitat conditions, and potential changes in predator communities. CPW will assess, on a
case-by-case basis, effects on declining or vulnerable species should
wolves expand to areas of the state occupied by these species. However, at this time it is not anticipated that there will be impacts on
certain species of concern, including Canada lynx or sage grouse, as
wolves are not known demonstrate extensive predation on grouse
(Centrocercus spp.).

Key Element 6: Wolves and
Human Safety Concerns
Attacks by wolves on humans are exceedingly rare. In North
America, there are no documented accounts of humans killed by
wild wolves between 1900-2000 (Mech et al., 1990, Linnell et al.,
2002, McNay 2002). Education and outreach for recreationists and
other public lands users should include best practices and guidance,
including how to differentiate between wolves and coyotes. Wolves
generally fear people and rarely pose a threat to human safety.
Human safety and specifically, human perceptions about wolf attacks and other concerns have been rigorously examined in the literature. Worldwide, conditions under which the majority of wolf
attacks on humans (resulting in injury or death) can be summarized
as follows (Linnell et al., 2021):
• Wolves afflicted with disease (principally rabies);
• Wolves suffering from starvation or other health-related conditions;
• Human guarding of livestock (typically children) where conditions have deprived wolves of wild prey (e.g., India);
• Wolf defense of territory and den sites (with pups present)
typically from domestic dogs;
• Wolf habituation to humans;
• Wolves exhibiting defensive behavior associated with food
sources, or when cornered or trapped.

can result in deaths and injuries
to dogs. Attacks on dogs are usually related to defense of pups at
dens or rendezvous sites or defense of territories rather than
acts of predation (Bangs et al.,

attacks on dogs occur in remote
areas away from homes (Bangs et
al., 2005a), but in a few cases,
wolves have come close to homes and fought with dogs, even when
people were present. Domestic dogs are also vulnerable to attack or
killing by a variety of predators other than wolves, including coyotes,
mountain lions, bears, and feral dogs.
As wolves expand their range in Colorado, dog owners will need
to be aware of the potential risks to their animals if they are within
wolf pack territories. Some wolves will occupy areas near human
habitation and areas with heavy recreational use (e.g., national forests), which could put hunting or pet dogs at risk of attack, especially
if they are running at large.

Key Element 7: Monitoring and
Research
Monitoring is an essential component of any wildlife management
plan; CPW collects survey and inventory data on a variety of fish
and wildlife populations. Monitoring is the measurement of a feature
of interest to inform future management efforts. The most immediate purpose of a post-release wolf monitoring program is to assess
and, if necessary, inform the modification of any logistical protocols
to ensure the highest likelihood of restoration success. These data
create the foundation upon which wildlife populations are managed
and provide the basis for support of continued management.
Once wolves are established, monitoring of their demographic
characteristics will inform the success and challenges that wolves
face in Colorado. Short-term and long-term monitoring will aid in
evaluating the efficacy, cost, and relative value of non-lethal and lethal conflict mitigation measures. Prey and other wildlife populations are already being monitored for a variety of management
purposes in the state. Some of these efforts will be supplemented, expanded, or lengthened to inform future management of wolves, prey,
and habitat.
Managing wolves in Colorado will require a suite of different
monitoring programs. These monitoring programs will balance scientific precision with cost effectiveness. The primary wolf monitoring responsibilities will rest with CPW. However, collaboration with
tribes, other state and federal agencies, colleges and universities,
landowners, local government, and the public will be essential to the
success of the monitoring program. This coordination will be especially important when monitoring packs near state borders or when
packs are located on or near tribal lands. Ultimately, a robust monitoring program will ensure that wolf management decisions are
made based on the most up-to-date science and data available.
Monitoring and Research actions are discussed in Chapter 7.

Activities in Colorado where humans are most likely to interact
with wolves include recreation (e.g., camping, hiking, hunting, fishing, wildlife viewing) and forest and rangeland work (e.g., timber
harvesting, fuel reductions, livestock grazing, and rural agricultural
activities). Wolves seasonally follow migrating ungulate herds, which
they rely on for food, and this may bring them into closer proximity
to people. In extremely rare cases, individual wolves may gradually
lose their fear of people and begin associating or interacting with
people or loitering near buildings, livestock, or domestic dogs. Such
behavior is extremely unusual for a wild wolf; it is more typical of a
released captive wolf or wolf-dog hybrid (Linnell et al., 2021). Nevertheless, CPW intends to reduce the potential for wolf-human conflicts and minimize the risks of human injury by wolves. CPW will
develop and disseminate extensive outreach to inform the public,
discourage habituation, and encourage conflict minimization techniques and then respond to conflicts where and when they develop.
As wolf numbers and distribution increase in Colorado, the public’s concern about human safety could increase. CPW will provide
information to the general public about appropriate responses
during wolf encounters (do’s and don’ts) and how to minimize the
potential for problems near homes and rural schools as is done with
black bear, mountain lions, moose, rattlesnakes, and other species in
the state. This material will also include information about wolf behavior, body posture, tail position, vocalizations, etc., to help the
public evaluate the situation, correctly interpret wolf behavior, and
communicate the details accurately to agency personnel. An educational effort will also help the public understand the differences between wolves, mountain lions, and bears in terms of animal
behaviors, appropriate human responses when threatened, and how
to live and recreate outdoors in the presence of these large carnivores.
Habituation of wolves to humans can occur in locations where
wolves commonly encounter people and may or may not involve
conditioning to human foods (McNay 2002, NPS 2003). Instances of
camp robbing by wolves have long been known (Young and Goldman 1944) and may develop from wolves finding novel or chewable
items (e.g., camping equipment, clothing) on a repeated basis in a
human setting. This type of conditioning does not involve the presence of food but can lead to unprovoked aggression toward humans
(see Linnell et al., 2002 for examples). Wolves can quickly develop
persistent aggressive approach behavior in situations where they receive food directly from people (McNay 2002). Habituated wolves
can remain non-aggressive toward humans for extended periods but
can quickly transition to strong aggressive or predatory behavior depending on the behavioral stimuli shown by humans (McNay 2002).
The federal Endangered Species Act provides that “...any person
may take endangered wildlife in defense of his own life or the lives of
others” (50 CFR 17.21(c)(2)). State regulation also makes it permissible to kill a state-listed wolf threatening human life (CPW

�Chapter 3:

Reintroduction Implementation
State statute codifying Proposition 114, as amended, requires that this Plan include: “…(I) The selection of donor populations of gray wolves; (II) the places, manner and scheduling of reintroductions of
gray wolves by the division, with such reintroductions being restricted to designated lands; (III) details
for the restoration and management of gray wolves, including actions necessary or beneficial for establishing and maintaining a self-sustaining population…” CRS 33-2-105.8(3)(a)(I-III). This chapter addresses those requirements.

missing incisors are not uncommon or cause for rejection. Animals
cleared for translocation will be treated for endo- and ectoparasites
and vaccinated for canid diseases of concern. Biologic samples, including blood, feces, and genetic material, will be collected for additional health screening and sample banking. All age classes, except
young of the year, are acceptable for translocation. Equal numbers of
each sex are desirable.
Wolves will be fitted with GPS collars that include supplemental
VHF capability. Collars will contain a mortality sensor and will be
programmed to collect at least one location per day that will transmit regularly via satellite interface. This will allow quick investigation
of mortalities and could provide valuable information for improving
program protocols. The collars will be the primary means for monitoring individual wolves post-release. Location data is not immediately available from these collars, it is subject to satellite download
frequencies, and it should be expected that there may be several
days, sometimes greater from when the animal was at the location
and the data are available.

Reintroduction Methodology
The TWG developed a detailed report on Restoration Logistics
Recommendations (Appendix B). Where details are not provided in
the plan, the reader is referred to the appendix where more in depth
discussion and rationale is evaluated. These recommendations will
guide actions taken by CPW as work to restore gray wolf populations to the state is implemented. This Plan relies heavily on the expertise and experience of this group to develop the reintroduction
protocols. Further, Bangs and Fritts (1996), Fritts et al., (1997) and
Fritts et al., (2001) provided a robust description of the considerations, methodologies, challenges, and successes of implementing
the reintroduction of wolves into Yellowstone National Park and
Central Idaho in the mid-1990’s. These sources were also invaluable
in developing these protocols.
This wolf reintroduction effort will be undertaken by CPW in cooperation with Federal agencies, potentially affected Tribes, and the
states of Idaho, Montana and/or Wyoming from which wild wolves
will be transferred via agreement. Specific agreements regarding
donor populations have been discussed with these three states but
final agreements have not yet been concluded. In the event that none
of these three states can serve as source sites for wolf donor populations, CPW has also begun to explore an agreement with the states
of Washington and/or Oregon. Matching to the extent possible the
ecological conditions at the capture and release sites (primary prey,
migratory/resident behavior of prey, likely denning habitat, etc.) is
important. In that sense, wolves across much of Wyoming, Montana,
Idaho, eastern Oregon, and eastern Washington would very likely be
well adapted for western Colorado, where the primary prey is likely
to be migratory elk that generally move from intermountain valley
or lower elevation winter ranges to high elevation summer ranges.
This Plan anticipates that wolf reintroduction efforts will require
the transfer of about 30 to 50 wolves over a 3-to-5 year period from
the NRM states, with assistance from other state wildlife management agencies. Based on the TWG recommendations, CPW will
aim to capture 10-15 wild wolves annually from several different
packs over the course of 3 to 5 years by trapping, darting, or net gunning in the fall and winter. These captures may be done by agency
staff, contractors, or private trappers. The total number of wolves relocated in any year and in total will depend on capture success, continued participation by the cooperating states, and the degree to
which relocated animals remain in Colorado and survive.
Pre-relocation animal processing will include a general health assessment by veterinarians and biologists to determine suitability for
translocation. They will assess body condition, estimate age and condition of teeth, examine for injuries, and survey for ectoparasites.
Criteria for rejection include excessive tooth wear, multiple missing
or broken teeth, emaciation, heavy ectoparasite loads, foot anomalies, fractures, and other signs of disease or injuries of concern as de-

All wolves to be translocated will be transported to western Colorado release sites by vehicle or aircraft in the most expedient and efficient manner. All efforts will be made to minimize the time that
animals are kept in a holding crate or temporary pen. Immediately
prior to transport, wolves will receive a final visual inspection by personnel trained to evaluate animal condition. Animal condition will be
evaluated periodically during transport. Signs that animals are experiencing high stress during transportation will compel review of protocol and may lead to modifications of transport crates or other aspects

�that could help reduce transport stress. In the case of animals that
incur severe injuries or health issues during capture or transport that
are likely to result in long-term pain or suffering or the inability to
hunt and survive after release, the animal will be humanely euthanized
under veterinary guidance (Underwood and Anthony 2020). If a licensed facility expresses interest and can demonstrate that they have
the physical infrastructure and financial capacity to care for a wolf that
is injured and deemed to not require humane euthanasia, this will be
considered. An analysis of the challenges of taking free-ranging wildlife and placing them in captivity would be conducted to ensure that
this is the best outcome. Wolves do not habituate easily, that the social
aspect of wolves can be very challenging when introducing a new animal into a captive population. There should be no expectation that
wolves that are placed in such a facility and become accustomed to humans would be considered for re-release.
Release Locations
A number of factors have been considered in determining the
most suitable and promising release sites, beginning with the need to
relocate wolves into suitable habitat. There have been many efforts at
modeling suitable wolf habitat in Colorado (Carroll et al., 2003, Carroll et al., 2006, Ditmer et al., 2022). These efforts have all come to a
similar conclusion: there appears to be adequate habitat in the state
to support a self-sustaining population of wolves. Ditmer et al.,
(2022), further evaluated and compared the ecological value of the
landscape for wolves in relation to the potential for conflict within
the human landscape (Figure 3).

approximately 22 to 140 miles from the release sites). Because of this,
releases in Colorado will be located a minimum of 60 miles from
Colorado’s borders with Wyoming, Utah, New Mexico, as well as a
similar buffer, as requested by the Tribes, of sovereign tribal lands in
southwestern Colorado (Figure 4). This geography should not be interpreted as the only places in the state where wolves will be tolerated or successful — this is only to inform initial release locations. It
is anticipated that wolves will expand widely over time, including to
the Front Range of Colorado. Furthermore, it is unknown whether
wolves will remain in proximity to initial release sites or range more
widely before establishing territories within suitable habitat. CPW
used the Ditmer et al., (2022) model to identify areas for consideration as release locations (Figure 4). Described in detail in Ditmer et
al., (2022), areas in green indicate high ecological suitability and low
modeled conflict risk. Areas that are pink are high conflict risk and
low ecological suitability. Areas that are white are low for both ecological suitability and conflict risk (these are high elevation areas as
depicted in the winter time map (Figure 3).

Figure 4. Area for consideration for wintertime releases of wolves.
60-mile buffers from neighboring states and tribal lands, and
areas west of the Continental Divide are depicted.

Figure 3. Ecological suitability and conflict risk of wintertime
landscape for wolves in Colorado (Ditmer et al., 2022).
Within Colorado, preliminary release locations are constrained by
several geographic criteria. State statute requires that wolves be released only west of the Continental Divide (CRS 33-2-105.8). Fritts
et al., (2001) found that wolves released in Yellowstone and central
Idaho moved substantial distances in the months immediately after
release (average distance was approximately 50 miles ranging from
Colorado Wolf Restoration and Management Plan

With the previously stated geographic restrictions in mind, two
large areas become apparent for consideration as wintertime release
sites in western Colorado. The northern area (generally depicted in
green) is along the I-70 corridor between Glenwood Springs and
Vail, and extends down the Roaring Fork Valley. The second, southern area (generally depicted in yellow) is along the Highway 50 corridor between Monarch Pass (east of Gunnison) and Montrose.
Based on the on-going evaluation of geographic mandates and constraints, relative conflict risk, and ecological suitability, and barring
the need to alter this Plan, release sites will be chosen from within
these identified north and south areas. Releases in the first year will
occur in the northern area only. Subsequent release sites will be considered based on the efficacy of the initial release, but will be located
21

�Post-Release Monitoring
There will be an immediate, and on-going need for post-release
monitoring to assess and modify reintroduction protocols if necessary. This will help to ensure the highest probability of survival for
subsequently released animals. Data from the wolves’ satellite GPS
collars will inform managers on survival and dispersal, as well as future release protocols. If necessary, subsequent translocation protocols will be modified, based upon information obtained during the
initial year of the reintroduction effort. Information gained from the
initial year of the project will contribute to an overall assessment of
the success of the reintroduction over time.
Location data from satellite GPS collars will be adequate to construct annual territory maps. Such location data will be used to determine areas of settlement by males and females and show gaps
where additional individuals could be released during the next
round of captures and translocations. As the annual process moves
forward, the data can also be useful for within-release-year decisions
on what release areas to target. For example, movements or apparent
settling of animals will inform subsequent release locations. The
overall goal is to better discern the establishment of breeding pairs
and reduce territorial conflicts with other wolves.
Evaluating Success of Reintroduction
After the release of 30-50 animals over the 3-to-5 year timeframe,
active reintroduction will stop, and post- release monitoring will apprise managers if the effort to establish a self-sustaining wolf population in Colorado has been successful.
The following established set of benchmarks will be used to evaluate the short-term success of wolf reintroduction efforts:
• Reintroduced wolves demonstrate a high rate of survival in
the first 6 months after release;
o A survival rate of less than 70% would initiate protocol
review (ODFW 2015).
• Released wolves demonstrate low mortality rates over the initial 2-3 years post-release;

If parameters are measured that indicate a growing population
that no longer needs supplemental active reintroductions, and the
wolf population demonstrates a positive growth rate from natural reproduction, the wolf population will be managed to grow naturally
toward recovery levels (see Chapter 4). If the population demonstrates an unacceptable flat or negative growth rate, or a high rate of
mortality is found, active augmentation would be reinitiated (after
evaluating what led to the initial unsuccessful result).
Private landowners, the general public, and other federal/state
agency personnel will be requested to immediately report any observation of a gray wolf to CPW. Illegal take of gray wolves by the public
will be discouraged through an extensive information and education
program, which will include reference to all initially transplanted animals being monitored daily through GPS satellite collars and radio
telemetry. Any reports of suspicious activity will be taken seriously
and investigated. The public will be encouraged to cooperate with
CPW in the attempt to closely monitor the wolves and quickly resolve any conflicts.

within or near the identified north and south areas.
Releases will occur on state or private lands. The plan does not
currently contemplate releases on Federal lands because CPW does
not have the staffing or financial resources to undertake the required
National Environmental Policy Act (NEPA) analysis prior to any
federal land management agency authorizing releases on federal
lands. CPW will attempt to select release areas that are likely to promote successful wolf recolonization, while also considering the potential for livestock or human conflicts. Specific release locations will
not be made public in this Plan in order to protect private landowner
information and sensitive species locations, but targeted outreach
will occur with potentially affected stakeholders prior to release.
Upon arrival in Colorado, animals will be immediately released in
areas identified as suitable habitat west of the Continental Divide.
This is commonly referred to as a “hard release,” in contrast to a “soft
release,” in which wolves are kept in pens at the release site for an extended period of time. No supplemental food or care will be provided once the wolves are released.

Data from the wolves’ satellite GPS
collars will inform managers on
survival and dispersal.

CPW will monitor transplanted wolves that emigrate into adjacent
states and assess management implications on a case-by-case basis in
consultation with that state’s wildlife management agency and the
USFWS. Such animals may be captured and relocated back to Colorado in the most efficient and effective manner possible.
Any unexpected losses of wolves to preventable causes will immediately prompt a review of all associated factors, and, if possible, find
ways to improve procedures. Unexplained losses or an unusually
large number of losses during the first year of releases or following
any modification to established protocols will prompt a full review of
management procedures. To assure high initial post-release survival,
the project may be suspended at any time until likely cause(s) of
problems are identified, and acceptable solutions can be implemented to resolve the problem(s).
Monitoring will occur over a longer time frame to assess when the
program has reached its benchmarks for success and completion
(Chapter 7).

• Wolves remain in Colorado;
• Reintroduced wolves successfully form pairs and reproduce,
establishing packs;
• Wolves born in Colorado survive and also successfully reproduce.

Colorado Parks and Wildlife

�Chapter 4:

Recovery of Wolves in Colorado
State statute requires that this Plan develop: “Methodologies for determining when the gray wolf population is sustaining itself and when to remove the gray wolf from the list of endangered or threatened
species, as provided for in Section 33-2-105 (2).” CRS § 33-2-105.8 (3)(iv). This chapter addresses this
responsibility.
Definitions for state endangered, threatened, and nongame species are as follows:
• Endangered Species: any species or subspecies of native wildlife whose prospects for survival or recruitment within this
state are in jeopardy as determined by the commission (CRS
§ 33-1-102 (12);
• Threatened Species: any species or subspecies of wildlife
which, as determined by the commission, is not in immediate
jeopardy of extinction but is vulnerable because it exists in
such small numbers or is so extremely restricted throughout
all or a significant portion of its range that it may become endangered. CRS § 33-1-102 (44).
• Nongame Species: all native species and subspecies of wildlife which are not classified as game wildlife by rule or regulation of the commission. CRS § 33-1-102(29).
As of February 10, 2022, wolves are listed under the federal Endangered Species Act as endangered. This Plan does not replace a
federal recovery plan, nor does it outline federal recovery goals.

Phased Management of Wolves
Wolves will be managed within Colorado using a phased approach, based on the number of animals present in the state. See
Table 2. These phases correspond with the status of the species on

the Colorado Threatened and Endangered Species list, and track the
definitions of “endangered species” and “threatened species” in
C.R.S. §§ 33-1-102(12) and 102(44). The thresholds were developed
through expert deliberation of the Technical Working Group
(TWG) members and are presented in a phased framework.
A phased approach provides clarity for current and future management, while still supporting the statutory requirement of managing for a self-sustaining wolf population. A phased approach allows
for increased management flexibility as the wolf population increases and provides the opportunity to manage conflict throughout
all phases.
A minimum wintertime count is the metric that will be monitored
in the early phases of reintroduction. This count will attempt to include all wolves in the state, whether they are wolves that have naturally migrated into the state and their progeny and those that were
reintroduced and their progeny. Any wolf anywhere in the state will
count towards the minimum count.
A minimum count is labor and resource intensive. Minimum
population counts have been used by Wyoming, Montana, and other
states during the early stages of the recovery process. As the wolf
population grows, minimum population counts are more difficult to
conduct and are less reliable for understanding total population size.
As the wolf population status transitions to a state delisted status,
CPW will use a population estimate or population models as a more
reliable metric (i.e., models based on distribution, vital rates, and
abundance estimates, etc.). These methods will be developed using
data that are collected during the minimum population counts and
other wolf monitoring/research activities.
We will apply a temporal trend threshold in the downlist and delisting criteria. This is important to ensure a trend of stable or increasing population, to account for
the temporary population increases
that occur through reintroduction,
and to allow for temporary fluctuations in population size or unforeseen monitoring challenges over
time. The interaction between minimum population count and the
length of time criteria can accommodate rapid or slow population
growth. For example, rapid population growth could eliminate the
need for a temporal requirement between phases.
Minimum counts for delisting are
not intended to be and should not be
interpreted as population objectives
or maximum target populations.
Specific management direction for
the phases is described in Chapter 5.

​​ o prescribed conclusion

Notes on framework:
ª Phases will be dictated by numeric and temporal wolf population thresholds described in the table. While it is intended that state status will also correspond to these thresholds, there may be a time lag as the Parks and Wildlife Commission undertakes the regulatory
process to change the state status based on population counts.
b Minimum population counts in any phase include gray wolves that have been reintroduced to Colorado, those that have naturally
migrated into the state, and the progeny of both groups. To reflect in situ recruitment most accurately, wolf population minimum counts
in this table refer to counts conducted in late winter.
c “Successive” means years in a sequence, with any number of gaps in between. Consecutive means years in a sequence with no gaps.
d Downlisting to State Threatened status may not occur until the four-successive year requirement is met in the State Endangered status phase 1 (Phase 1). However, the two-successive year timeline for the phase 2 minimum count requirement begins when the minimum number is first met and may occur concurrently while in the Phase 1/endangered phase. Consequently, it is possible that delisting
(conclusion of Phase 2) may occur immediately after Phase 1, should the Phase 2 requirements be met concurrently during Phase 1.
Phase 1 (State Endangered):
“Phase 1” refers to when the wolf is classified by Commission rule
as an endangered species under state law. This first phase includes
the early years of wolf reestablishment when population size is small.
During this phase, the initial wolf population will be managed in accordance with state policy to conserve species listed as endangered
under Colorado’s Nongame, Endangered, or Threatened Species
Conservation Act (CRS § 33-2-101). All state management of wolves
will comply with any superseding Federal status and associated rules
or regulations. The Commission may pass regulations related to this
Plan. In the event of any conflicts between the Plan and such regulations, such regulations will control.
This Plan will remain in Phase 1 until CPW biologists document a
minimum wintertime count of 50 wolves anywhere in the state for
four successive years. A temporal requirement of successive minimum population counts for downlisting to threatened is important
to ensure a trend of a stable or increasing population, to account for
the temporary population increases that occur through reintroduc24

tion, and to allow for temporary fluctuations in population or unforeseen monitoring challenges over time.
Once the criteria are met to move from Phase 1 to Phase 2, the
regulatory process to downlist to state threatened will begin. The
Commission will take the most time-efficient manner to conduct
the downlisting processes to state threatened through the CPW
Chapter 10 regulation process.
Phase 2 (State Threatened):
“Phase 2” refers to when the wolf is classified by Commission rule
as a threatened species under state law. Phase 2 is characterized by
subsequent periods with increased population growth and spatial
expansion of packs into suitable habitat and multiple years of data to
base management decisions. Phase 2 will correspond to the time
when the Colorado wolf population’s growth is driven more by natural reproduction than by active reintroduction. This phase is envisioned as a period when wolves expand into and inhabit suitable
areas throughout Colorado.
Colorado Parks and Wildlife

�Phase 2 will begin after CPW confirms a minimum count of 50
wolves anywhere in Colorado for four successive years and will conclude when a minimum count of at least 150 wolves anywhere in
Colorado is measured for 2 successive years, or a minimum count of
at least 200 wolves anywhere in Colorado is measured, with no temporal requirement and are not so extremely restricted throughout all
or a significant portion of their range that it may become endangered. This will correspond to a time when wolves will be removed
(delisted) from the State Threatened and Endangered Species List. At
that time their status will be “nongame wildlife.”
The transition from state endangered to state threatened cannot
occur until the four-successive year requirement is met in Phase 1.
However, the two-successive year time constraint to transition from
Phase 2 to Phase 3 begins when the minimum count of 150 wolves is
first met and may occur concurrently while in Phase 1. Consequently, it is possible that delisting (conclusion of Phase 2) may
occur immediately after meeting the threshold for transition from
Phase 1 to Phase 2, should the Phase 2 requirements be met concurrently during Phase 1.
Taking a conservative estimate of a pack size of 8 animals, a population of 200 wolves would have approximately 25 packs on the landscape. Assuming each pack has a conservative territory size of
180mi2, there would be nearly 2.8 million acres of occupied wolf territory when the minimum population size is 200. CPW feels confident in stating that the distribution of wolves throughout Colorado
would represent a secure population and that the species should no
longer be considered state threatened when that numerical threshold
has been met.
As in the transition from Phase 1 to Phase 2, there may be a regulatory lag moving from Phase 2 to Phase 3. This regulatory process
will be completed in the most expeditious manner possible.
At the time that the Parks and Wildlife Commission is considering delisting the species, CPW will conduct a Population Viability
Analysis, or similar population modeling effort. This would be done
to assess the extinction probability of the wolf population in Colorado, using Colorado-specific demographic parameters gained from
research and monitoring the population in the state in the years be-

tween reintroduction and recovery. An effort similar to ODFW
(2015) is suggested as a model for comparison.
Phase 3 (Delisted/Nongame species status):
“Phase 3” refers to when the wolf is classified as a nongame species under state law and is no longer listed on the Commission’s list
of threatened or endangered species. This phase is characterized by a
sustained wolf population which continues to grow, though the rate
of growth will likely decrease over time.
Phase 3 will begin after CPW confirms that there are at least 150
wolves anywhere in Colorado for two successive years, or a minimum count of at least 200 wolves anywhere in Colorado, with no
temporal requirement. Once this threshold is met, the species will be
reclassified to delisted, nongame status.
A wolf population of 150-200 animals is not considered a minimum or a maximum allowable number of wolves and is not a management objective. The value of 150-200 is used to determine when
the gray wolf population is sustaining itself and when to remove the
species from the list of endangered or threatened species because it
no longer fits the definition of state endangered or state threatened.
Long Term Wolf Management:
At some point in the future, the long term management of wolves
in Colorado may need to be considered further than what is outlined
in this plan. These discussions would only occur after wolves have
successfully been recovered and removed from the State Threatened
and Endangered list. The long-term management of wolves should
be impact- and science-based, with consideration of biological and
social science as well as economic and legal considerations.
CPW will defer consideration of and development of specifics for
long-term management until the beginning of Phase 3 at the earliest,
when better information about wolves and their distribution in Colorado is available. Future management will be guided by the best
available biological and social science data provided by CPW.
This plan takes no position as to whether the Parks and Wildlife
Commission has the statutory authority to reclassify wolves as a
game species or take other appropriate management actions.

Taking a conservative estimate of a pack size of
8 animals, a population of 200 wolves would
have approximately 25 packs on the landscape.

Colorado Wolf Restoration and Management Plan

25

�Chapter 5:

Wolf Management
By passing CRS 33-2-105.8, Colorado voters declared that “Restoration of the gray wolf to the state
must be designed to resolve conflicts with persons engaged in ranching and farming in this state” (33-2105.8(1) (d).
State statute requires that this plan provide “[d]etails for the restoration and management of gray
wolves, including actions necessary or beneficial for establishing and maintaining a self-sustaining population, as authorized by Section 33-2-104” (CRS 33-2-105.8 (3)(a)(III)).
Further, state statute requires that “the commission shall not impose any land, water, or resource use restrictions on private landowners in furtherance of the plan” (CRS 33-2-105.8(3) (IV) (b)).
This chapter addresses those responsibilities.

Management Limitations
Legal Considerations
The legal status of wolves at federal and state levels impacts management options and flexibility. A primary challenge for CPW in developing and implementing this Plan is that the uncertainty and
longevity of federal listing of wolves as a Federally Endangered Species affects the state’s ability to manage the species using a variety of
management techniques, including lethal take. As stated earlier, all
management of wolves in Colorado will be done in compliance with
all state and federal laws and regulations.
Concurrent with Plan development, at CPW’s request, USFWS
has embarked on a rulemaking process designed to provide management flexibility by designating Colorado’s wolves as an experimental
population under section 10(j) of the federal ESA. USFWS anticipates that the resulting 10(j) rule will take effect prior to the reintroduction of wolves into the state, as was done when wolves were
reintroduced into the NRM in the mid-1990s. The 10(j) rule provides management flexibility that is a critical component to the success of this Plan and on which other components of the Plan
depend.

Following reintroduction, some forms of aversive conditioning
and lethal take to protect human safety, to reduce livestock depredation, or to mitigate risks of substantial effects on ungulates will be
necessary management tools. These management options are limited, however, while the gray wolf is listed as endangered or threatened under state or federal law. If the legal status of Colorado wolves
changes, including the anticipated adoption by USFWS of a 10(j)
rule to direct management of wolves in the state, CPW expects to
have increased management flexibility, including authority to lethally remove wolves for management purposes consistent with this
plan. Additional regulatory changes will likely be necessary to provide mechanisms to resolve depredation of livestock by wolves as
well as to mitigate for other possible conflicts.
It is the duty of the Commissioner of Agriculture to control depredating animals in the state of Colorado to reduce economic losses to
agricultural products or resources. Colo. Rev. Stat. § 35-40-101(1).
To fulfill this duty, the Commissioner may adopt rules for the control of depredating animals, in consultation with the Parks and
Wildlife commission; establish lethal and nonlethal methods of controlling depredating animals; and allow state employees and owners
of agricultural products or resources and their families and employees to control depredating animals. Colo. Rev. Stat. § Section 35-40101(2.
With respect to at-risk depredating animals, the Commissioner,
when adopting rules, must receive approval from the Colorado
Parks and Wildlife Commission of any proposed rules. Colo. Rev.
Stat. § 35-40-101(4)(a).

Impact-Based
Management

All management of wolves in Colorado will be
done in compliance with all state and federal
laws and regulations.

26

This Plan is predicated on managing wolves in Colorado using “impact-based” management within an
adaptive management framework
that will allow the State the maximum
flexibility to manage wolves while
learning how they affect Colorado’s
ecosystems (see Chapter 2 for detailed discussion).
The assumptions inherent in this
impact-based approach are that the
presence of wolves in Colorado will
have both positive and negative impacts. The positive impacts of having
wolves on the landscape will be recognized and used without having to
implement direct wolf management
Colorado Parks and Wildlife

�practices. Positive impacts may include, but are not limited to the
following: 1) providing complementary offtake of ungulates in management units where they are overpopulated; 2) dispersal of wild ungulates that may result in habitat improvement due to less herbivory
on vegetative communities; 3) selective removal of diseased animals
from herds; and 4) social, economic or non-monetary values, such
as intrinsic value, existence value, and other possible values for present and future generations. The negative impacts of wolves may require direct intervention. Negative impacts can include, but are not
limited to the following: 1) depredation and harassment of livestock;
2) loss of pets, herd dogs and guard animals; and 3) contributing to
declines below management objectives in ungulate populations or in
ungulate recruitment rates. This chapter describes what interventions may be implemented to address the negative impacts of having
wolves on the landscape. The management herein will comply with
federal and state laws and regulations.
It must be emphasized that not all impacts can be predicted and
that future management flexibility is crucial for adaptively managing
impacts as they arise. With such uncertainty, the spectrum of potential management actions cannot be prescribed by this Plan.
Three primary categories of conflict and specific management
considerations are defined. The three categories of impacts are: Livestock Interactions, Wildlife Species Interactions, and Other Situations. For each of these categories, the impact and management tools
are described. The deployment of these tools may be affected by the
Phase (see chapter 4 and Table 2) of the wolf population, which is
also described.
Livestock Interactions
IMPACT: Wolves are present, but not biting, wounding, grasping or
killing, and not chasing livestock, and there have been no prior depredations or attacks.
In this situation, the appropriate management tools to consider
are education; non-lethal, non-injurious conflict minimization techniques (e.g., fladry, range riders, livestock guardian dogs); or non-lethal, potentially injurious conflict minimization techniques (e.g.,
rubber buckshot, rubber slugs, bean bag projectiles).
Non-lethal, non-injurious hazing of wolves includes scaring off an
animal(s) by making loud noises (e.g., confronting the animal(s)
without doing bodily harm). See CPW Regulation #1000. These
tools are acceptable in all Phases of wolf management. Non-lethal
potentially injurious hazing means scaring off a wolf (or wolves)
without killing but with potential for minor injury to the wolf. Training for material deployment will be provided by CPW staff at the
time of materials are delivered.
If a known injury or death of a wolf occurs as a result of hazing,
CPW must be notified within 24 hours. Death or injury as a result of
translocation of wolves and lethal management of wolves are not
considered for this impact.
IMPACT: Wolves are observed in the act of biting, wounding, grasping
or killing livestock, or are observed in the act of chasing livestock.
While the likelihood of observing a wolf in the act of biting,
wounding, grasping, killing, or chasing is low, and the likelihood of
implementing lethal control in this context is also low, this management approach provides livestock owners with tools to respond,
should the situation occur.
For this impact, management options include non-injurious, conflict minimization techniques (e.g., fladry, range riders, livestock
guardian dogs); or potentially injurious hazing techniques (e.g., rubber buckshot, rubber slugs). Nonlethal tools should be explored and
encouraged before lethal tools are used. Lethal management should
not generally be a first line of defense. A permit is required for priColorado Wolf Restoration and Management Plan

vate landowners and their agents in Phases 1 and 2 to provide for lethal control of wolves caught in the act of biting, wounding,
grasping, or killing livestock or working dogs.
Such scenarios where lethal control is implemented must be reported to CPW within 24 hours, unless impractical, but in no event
later than 72 hours, and will be expeditiously investigated. A preponderance of evidence, including dead or injured livestock or working
dogs, or other physical evidence should be present, which would
lead a reasonable person to believe that a depredating wolf or wolves
were involved, or that a wolf attack on livestock or dogs was occurring or imminent.
In Phases 1 and 2, a limited duration permit for lethal take may be
issued to a livestock owner or agent of the livestock owner on private
or public land. A permit is required under state law (CRS 33-2106.4). Non-lethal conflict mitigation measures will be considered
prior to issuance of any lethal take permit.
In Phase 3, the same permitting requirements exist. Further coordination with Colorado Department of Agriculture will be required
as well per Colo. Rev. Stat. § 35-40-101(4).
IMPACT: Confirmed depredations (injury or death) of livestock by
wolves.
Management actions following confirmed depredation by wolves
include education, both non-injurious and potentially injurious hazing as described above, and lethal control. The translocation of depredating wolves to a different part of the state will not be considered,
as this is viewed as translocating the problem along with the wolves.
The lethal control of chronically depredating wolves following
depredation events will be conducted by state or federal agents (consistent with applicable law) if determined to be appropriate, after an
evaluation of the circumstances, in all phases.
Limited duration permits for lethal take may be issued to livestock
owners or agents on public or private land after evaluation of circumstances, as described above. These permits will only be issued if
state or federal agencies do not have the capacity to implement onthe-ground lethal control actions themselves. This action requires
reporting and an investigation that demonstrates evidence that justifies the act.
There is not a specific definition of a “chronically depredating”
pack or wolf. CPW program managers will make the determination
as to whether a situation is characterized as chronic depredation on a
case-by-case basis. A full evaluation of the circumstances will include considerations such as: 1) documented repeated depredation
and harassment in a limited geography caused by the wolf or pack
targeted; 2) previously implemented practices to reduce depredation;
3) likelihood that additional and continued wolf related mortality
would continue if control is or is not implemented; and 4) unintentional or intentional use of attractants that may be luring or baiting
wolves to the location.
Wildlife Species Interactions
IMPACT: Wolves are present, and there are no apparent population
level impacts to other wildlife species.
In this situation, there are no direct wolf management actions necessary. Education and outreach to the general public and others will
continue (see Chapter 8).
IMPACT: Ungulate populations are below objectives in a geographic
unit or area (i.e., DAU), and wolves are a suspected causal agent.
Lethal control of wolves in this situation may be allowed by state
or federal agents with considerations.

27

�In considering an appropriate management response to wild ungulate impacts, CPW will require:
• Data or other information indicating that wolves are a known
factor of ungulate herds not meeting objectives.
• CPW will consider the following:
° Level and duration of wolf removal necessary to
achieve management objectives;
° Ability to measure ungulate response to management
actions;
° Identification of other potential major causes of an
ungulate population not meeting HMP population
objectives and attempts made to address them;
° Decline in ungulate license quotas and hunting opportunities
A management response to wild ungulate impacts will not be considered until Phase 3, as it is not anticipated that wolf population
sizes in Phases 1 or 2 could demonstrably be shown to have an impact on ungulate population metrics that would justify this act. Empirical data must support the conclusion that wolves are a principal
cause in affected ungulate populations. In employing this management action, wolf removals must not contribute to reducing the wolf
population in the state below 150 wolves (returning to Phase 2).
IMPACT: Populations of wildlife species other than ungulate prey are
significantly reduced or likely to be extirpated due to the presence of
wolves.
This is not expected to occur, though there may be situations
where, with higher wolf populations (i.e., Phase 3), there may be
some yet undetermined impact on the sustainability of some wildlife
species of concern at a biologically meaningful scale for recovery.
Considerations similar to what is described immediately above for
ungulate impacts would be evaluated to determine if management of
wolves is warranted. Based on knowledge and experience in other
Rocky Mountain states and input from the TWG, it is not expected
that wolves will have any impact on Canada lynx or sage-grouse
populations.
Other Situations
IMPACT: Wolves are present and no human health or safety risks are
posed.
There are no wolf management actions warranted in this situation. General education and outreach is appropriate to potentially affected publics.
IMPACT: Wolves attacking or have attacked humans. Lethal control
of wolves in defense of human life is allowed under both state and federal law.
The lethal control of wolves that have attacked (but are not in the
act of attacking) may be employed by state or federal agents in any
phase of wolf management in the state.

IMPACT: Wolves found to be denning within municipal boundaries or
a high-density human population area.
The removal of a denning pack is allowed in all phases of wolf
management but must be conducted by state or federal agents.
Translocation of the pack will be considered and implemented if
possible.
IMPACT: Agency wolf management.
Take (non-lethal and lethal) by state and federal agents is allowed
for efforts related to the release, tracking, monitoring, recapture, and
management of wolves in Colorado; to aid or euthanize sick, injured,
or orphaned wolves or to transfer to a licensed veterinarian for care;
to dispose of a dead specimen; to salvage a dead specimen that may
be used for scientific study; to aid in law enforcement investigations
involving wolves; or to remove wolves with abnormal physical or behavioral characteristics from passing on or teaching those traits to
other wolves.
In an effort to inform future actions and wolf management related
to controlled take, CPW will monitor the results and evaluate the
impacts of any wolf removal. CPW anticipates that additional relevant information will continue to become available as physical and
ecological conditions in Colorado continue to change, legal frameworks and authorities may change, and CPW staff gain additional
experience with wolves.
Some management activities are unaffected by the legal status of
wolf populations in the state. These include:
• Research on wolf/ungulate interactions that doesn’t result in
injury or death;
• Health and disease surveillance;
• Research on management action efficacy;
• Law enforcement;
• Public outreach and education;
• Interagency coordination;
• Annual reporting;
• Non-lethal conflict minimization techniques;
• Technical assistance to landowners and livestock owners;
• Compensation programs for confirmed livestock losses;
• No compensation programs for loss of pets or hunting dogs.

IMPACT: Wolves attacking a pet or hunting dog.
Lethal control of wolves in the act of or having recently attacked a
pet or hunting dog is not allowed in any Phase. This is consistent
with other game damage laws and regulations (CRS 33-3-106).

�Table 3. Circumstances and associated wolf management tools
Circumstance

Management Tool

Non-injurious, nonlethal conflict
minimization practices by
livestock owners or their agents

Opportunistic hazing of any gray wolf in a non-injurious manner is permitted at any time. If a known
injury or death occurs, CPW must be notified within 24 hours unless impractical, but no later than 72
hours.

Potentially injurious non-lethal
hazing techniques by a livestock
owner or their agent

Opportunistic hazing of any gray wolf in a non-injurious manner is permitted at any time. If a known
injury or death occurs, CPW must be notified within 24 hours unless impractical, but no later than 72
hours.

Take in self defense

Any person may take a gray wolf in defense of the individuals life or life of another person.

Agency take of wolves determined
to be a threat to human life and
safety

State or Federal agent may promptly remove any wolf that is determined to be a threat to human life or
safety.

Taking of wolves in the act of
attacking or chasing livestock

A retroactive permit may be issued to any landowner that takes a gray wolf in the act of attacking livestock on their private land or state or federal land that they are legally grazing. A landowner must provide evidence of livestock, stock animals recently (within 24 hours, unless impractical, but no later
than 72 hours) wounded harassed or killed by wolves and state or federal agents are able to confirm
that the animals were attacked by wolves. The carcass of any wolf taken and the area surrounding it
should not be disturbed in order to preserve physical evidence.

Agency take of chronic
depredating wolves

State or federal agents may carry out hazing, non-lethal control measures, or lethal control of problem
wolves. CPW or its designated agents will consider A) evidence of wounded livestock, working dogs,
or other animals or remains of livestock that show that the injury or death was caused by wolves, B)
the likelihood that additional wolf-caused losses or attacks may occur if no control action is taken, C)
evidence of unusual attractants or artificial or intentional feeding of wolves and D) evidence that
proper animal husbandry practices are implemented.

Livestock owner or their agents
This will only be conducted using limited duration permits if state/federal agents do not have the retake of chronic depredating wolves sources to implement on-the-ground lethal control actions.
Agency take to reduce impacts to
wild ungulates

Only considered in Phase 3. In considering an appropriate management response to wild ungulate impacts, CPW will require:
• Data or other information indicating that wolves are a known factor of ungulate herds not
meeting objectives.
• CPW will consider the following:
° Level and duration of wolf removal necessary to achieve management objectives;
° Ability to measure ungulate response to management actions;
° Identification of other potential major causes of an ungulate population not meeting
HMP population objectives and attempts made to address them;
° Decline in ungulate license quotas and hunting opportunities
In employing this management action, wolf removals must not contribute to reducing the
wolf population in the state below 150 wolves.

Agency take to reduce impacts to
other wildlife species

Only considered in Phase 3, with similar considerations as described for wild ungulates

Additional take provisions for
agency employees

Any employee or agent of CPW or USFWS or appropriate state or federal or tribal agency, who is designated in writing, when acting in the course of official duties may take a wolf from the wild if such actions is for (1) take related to the release, tracking, monitoring, recapture, and management of wolves;
(2) to aid or euthanize sick, injured, or orphaned wolves or transfer to a licensed veterinarian for care;
(3) to dispose of a dead specimen; (4) to salvage a dead specimen that may be used for scientific study;
(5) to aid in law enforcement investigations involving wolves (collection of specimens for necropsy,
etc.); or (6) to remove wolves with abnormal physical or behavioral characteristics, as determined by
the Service or our designated agent, from passing on or teaching those traits to other wolves.

�Wolf Specimen Disposition
Possession of gray wolf parts is regulated by the ESA (when the
species is federally listed), as well as state regulations. Wolf carcasses
and parts may be discovered by or otherwise become available to the
general public for a variety of reasons, including natural mortality,
accidental death, agency control actions, or defense of life. It is not
legal to possess parts of wildlife legally classified as threatened or endangered unless there are provisions for regulated public take — i.e.,
special regulations written for state listed or nongame species. Any
person who possesses a dead wolf or wolf parts must adhere to all
federal and state laws or regulations from the state or country the
animal originated from. Additionally, any part must adhere to transport and import laws and regulations.
Any wolf carcass found in the field should be left alone and reported to CPW. CPW or APHIS will conduct a field investigation
and retrieve the carcass as a precautionary measure for public safety.
If a wolf were to be poisoned, there are potential public health concerns. All carcasses, including those resulting from APHIS control
actions or private actions through defense of life, will be transferred
to CPW and remain state property.
The entire carcass of wolves killed by private individuals in defense of life will be returned to CPW and remain state property, regardless of whether the incident occurred on public or private lands.
Upon confiscation, carcasses resulting from illegal killings also remain the property of CPW.
If the hide, bones, or skull are in good condition, they can be salvaged and used for educational purposes. Priorities will be for research purposes, tribal cultural use, and general wolf education.
These specimens may be transferred to other government agencies,
non-profit organizations, tribal authorities, or educational institutions for general public benefit. Parts unsuitable for educational uses
will be destroyed.
Land Use Restrictions
State statute requires that “The commission shall not impose any
land, water, or resource use restrictions on private landowners in
furtherance of the plan.” CRS 33-2-105.8 (3)(b).

There will be no Commission-imposed land use restrictions
placed on private landowners due to the release of or presence of
wolves. Neither the presence of naturally migrating wolves nor
CPW’s release of wolves constitute a land use restriction. Similarly,
statutes and regulations preventing landowners from harassing, injuring, or killing wolves do not constitute land use restrictions because wildlife is owned by the state and the ability to harass, injure,
or kill wildlife upon one’s own land does not implicate a private
property right. Federal land management agencies have sole management discretion over their lands. CPW has no legal authority to
implement restrictions or land management prescriptions on lands it
does not own or lease. Therefore, it will be important for federal
agencies and CPW to collaborate on land use issues as they relate to
wolf management, which may include recreation, grazing management, public access, or habitat manipulation. CPW will facilitate
on-going collaboration with Federal land managers in instances
where wolf presence or behavior may warrant temporary public land
access restrictions.
Managing for landscape scale movement
Safe passage within and between habitat areas is vital for allowing
wolves to recolonize unoccupied habitat and for promoting genetic
and demographic exchange between subpopulations, as it is for
many wildlife species in Colorado.
In Colorado, areas of greatest importance for restoring or maintaining connectivity between regions of suitable wolf habitat currently include various areas through western Colorado, primarily
connecting areas that would likely have minimal interaction with
livestock.
Other areas may be recognized in the future. Mechanisms to conserve lands and maintain working landscapes include conservation
easements, agreements or land acquisitions with willing landowners,
and other methods. Where appropriate, working with the Colorado
Department of Transportation to create wildlife crossing structures
for assisting wolf movement across highways that act as barriers can
be a beneficial and productive effort towards wolf management and
conservation.

�Chapter 6:

Wolf-Livestock Interactions
State statute requires that the Plan: “(I) Assist owners of livestock in preventing and resolving conflicts
between gray wolves and livestock; and (II) Pay fair compensation to owners of livestock for any losses of
livestock caused by gray wolves, as verified pursuant to the claim procedures authorized by sections 333-107 to 33-3-110.” CRS 33-2-105.8 (2)(e)(I, II). This chapter addresses those responsibilities. Providing
fair compensation to livestock owners for economic losses when livestock are injured or killed by wolves
is a necessary and critically important part of the Plan.
Ever since wolves naturally migrated into Colorado (Table 1), despite the lack of statutory and regulatory codification, CPW has been
investigating reported livestock depredation by wolves in the same
thorough and professional manner the agency has been investigating
black bear or mountain lion damage to livestock.
CPW will continue to respond to and investigate wolf-livestock
depredations in a timely and accurate manner, implement conflict
minimization and other management actions to minimize damage
from recurring, and provide monetary compensation to livestock
owners for confirmed wolf depredations.
Compensation programs vary greatly across the U.S. and are typically complex and often misunderstood. This is partly attributed to
differences in how each state funds and administers their respective
programs and the mechanisms by which livestock owners are compensated for damages.
CPW’s existing big game damage program is authorized in Article
3 of CRS Title 33 and codified in CPW Chapter 17 Regulations and
does not include wolves since they are not a big game species. Since
its inception over ninety years ago, this program has changed very
little and is funded entirely through annual appropriations from the
wildlife cash fund, which includes hunting and fishing license revenue. CPW’s wolf-livestock compensation and conflict minimization
plan is independent of the big game damage and prevention program and the statutes and regulations pertaining to damage by big
game wildlife. Wolf-specific conflict minimization and compensation procedures will be codified through CPW regulation. The
Commission may pass regulations related to this Plan. In the event
of any conflicts between the Plan and such regulations, such regulations will control.
Pursuant to CRS 33-2-105.8 (4.5), CPW’s wolf-livestock damage
program shall be appropriated by sources other than the sale of
hunting and fishing licenses or from associated federal grants. CPW
will pursue a variety of funding sources for wolf-livestock compensation and conflict minimization to develop sustainable and robust
wolf-livestock compensation and conflict minimization programs.
It is difficult to anticipate the amount of wolf-livestock conflict
that will occur as wolf numbers increase in Colorado. The Conflict
Minimization and Compensation sections establish a process and
framework for how CPW will address these issues. However, it will
be important to periodically evaluate this program in the future to
ensure that it is meeting the intent of Proposition 114, as recited at §
33-2-105.8, and evolving as needed.
Wolf-livestock Compensation and Conflict Minimization Planning Process
Throughout 2021 and 2022, CPW, the SAG, and the TWG discussed the technical and social considerations of a wolf-livestock
compensation and conflict minimization plan to ensure livestock
Colorado Wolf Restoration and Management Plan

owners are fairly compensated and to assist livestock owners in preventing and resolving wolf-livestock conflicts. During these meetings, the SAG developed wolf-livestock conflict minimization and
compensation recommendations (Appendix C).
CPW staff developed the conflict minimization plan based on
technical and social considerations from the TWG and SAG as well
as input from other state and federal wildlife management agencies.
CPW Conflict Minimization Program
To better assist livestock owners in preventing and resolving conflicts between wolves and livestock, CPW hired a Wolf Conflict Coordinator to serve as the statewide subject matter expert on
wolf-livestock conflicts. This position works proactively with CPW
staff, internal workgroups, NGOs, livestock stakeholder groups, and
state and federal agencies to identify, coordinate, implement and
evaluate a variety of conflict minimization techniques and methods
to minimize wolf-livestock conflicts. This position also develops and
implements education, outreach, and training to livestock owners,
CPW staff, and the general public on conflict minimization technique use, application, and maintenance. The coordinator will continually monitor and evaluate effectiveness at the local, community,
and statewide level to ensure success of the conflict minimization
program.
To meet the intent of CRS 33-2-105.8, CPW will provide the following temporary conflict minimization materials including:
• Turbo fladry: electrified fencing with flagging designed to
prevent wolves from entering an area.
• Scare devices: shell-crackers, propane cannons, and foxlights.
CPW will also determine if novel techniques that are developed
after this plan is implemented may be useful and practical for livestock owners and CPW. Conflict minimization hazing techniques
must comply with state and federal regulations and must be authorized by the USFWS while wolves are federally listed.
These temporary conflict minimization materials will be provided
to livestock owners on a case-by-case basis. When providing these
materials, CPW may evaluate the risks to livestock, including, but
not limited to, proximity of wolves to livestock based on monitoring
data; previous depredating/non-depredating behavior of wolf pack;
whether there has been a confirmed wolf-livestock depredation, etc.
Temporary conflict minimization materials will be loaned to livestock owners only by written request on a form furnished by CPW
staff and such materials will be delivered by CPW with instructions
on their use and installation. If available, CPW staff may assist with
deploying materials like fladry and fox lights.
31

�CPW will also provide education to livestock owners on other
conflict minimization techniques (e.g., carcass management, herders/range riders, herd composition, etc.) that are identified and recommended in CPW’s Wolf Resource Guide (https://cpw.state.co.us/
Documents/Wolves/Wolf_Hands-on_Resource_Guide_Depredation_Prevention.pdf).
CPW’s conflict minimization plan funding will be separate from
funding used for wolf-livestock compensation. This will allow members of the public and NGOs to help contribute funding to CPW
knowing that their contributions will be used for specific elements of
the wolf management program. Further, CPW will develop specific
procedures for providing conflict minimization materials, support,
and training to livestock owners through establishment of CPW regulation. This plan relies heavily on the SAG-developed conflict minimization elements, principles and funding and capacity
recommendations referenced in the SAG Recommendations for preventative, non-lethal, wolf-livestock conflict minimization report
(Appendix C). CPW will also seek external funding to support projects and materials and coordinate the efforts of NGOs, and agencies
to effectively minimize wolf-livestock conflicts. Secure, long-term
funding will be critical for the success of the Conflict Minimization
Program.
CPW Compensation Program
Pursuant to CRS 33-2-105.8, CPW shall pay fair compensation to
livestock owners for any losses of livestock caused by gray wolves, as
verified pursuant to the claim procedures authorized by sections
CRS 33-3-107 to 33-3-110. Therefore, CPW’s wolf-livestock compensation plan incorporates the damage claim procedures statutes
enumerated in CRS 33-3-107 to 33-3-110.

© CPW PHOTO

Many studies indicated that it can be difficult in open range
settings to find calves that are depredated by wolves since
those animals are more likely to be entirely consumed.

CPW’s wolf-livestock compensation program provides 100 percent fair market value (FMV) compensation, up to a maximum of
$15,000 per animal, for the confirmed death of livestock (cattle,
horses, mules, burros, sheep, lambs, swine, llama, alpaca, and goats
pursuant to CRS 33-2-105.8(5)(c)), as well as guard/herding animals.
32

Conflict minimization techniques are not required to be eligible for
compensation; however, CPW will work with livestock producers to
implement such techniques to reduce the risk of further depredations. Veterinarian costs for the treatment of livestock and guard/
herding animals that have been injured as a result of wolves will be
compensated up to the FMV of the animal not to exceed $15,000. If
the animal receiving veterinarian care dies due to injuries inflicted
by wolves, compensation will be limited to the animal’s FMV, not to
exceed the $15,000 per animal limit and additionally veterinarian
expenses up to the FMV of the animal not to exceed $15,000.
CPW will base all wolf-livestock depredation confirmations on a
preponderance of the evidence standard, which is currently the same
standard used for big game damage investigations. Preponderance of
the evidence means it is more probable than not that damage was
caused by wolves. Determination of 100 percent FMV for livestock,
will be based on the same standard as CPW regulation W17, Article
4, #1742 (https://cpw.state.co.us/Documents/RulesRegs/Regulations/
Ch17.pdf) used for big game damage to livestock and personal
property used in the production of raw agricultural products (guard/
herding dogs). Compensation for wolf damages by CPW shall be reduced by the amount of other financial support, including payments/claims awarded by an insurance company for the same
damages.
CPW conducted an extensive review of published, peer-reviewed
wolf-livestock compensation literature and other sources (Bangs and
Shivak 2001; Switalski et al., 2002, Montag 2003; Nyhus et al., 2003,
Oakleaf et al., 2003; Bradley et al., 2005; Bradley and Pletscher 2005;
Wydeven and Park Falls 2007; Collinge 2008; Muhly and Musani
2009; Agarwala et al., 2010; Laporte et al., 2010; Sommers et al.,
2010; Breck et al., 2011; Hebblewhite 2011; Steele et al., 2013; Rambler et al., 2014; Wieglus and Peebles 2014; Clark et al., 2017; Morehouse et al., 2018; Harris 2020; Macon 2020; Nickerson 2021;
USFWS 2021; Valerio et al., 2021).
Many of the studies listed above indicated that it can be difficult in
open range settings to find calves and all age classes of sheep that are
depredated by wolves since those animals are more likely to be entirely consumed or missing, whereas larger livestock were not. Additionally, livestock owners could incur economic losses (hereafter
referred to as production losses) other than the direct loss of an animal, that can lead to decreased weights, increased stress, decreased
conception rates, and other related impacts (Steele et al., 2013, Rambler et al., 2014).
Because of the challenges of running livestock with wolves on the
landscape, CPW has developed the additional compensatory mechanisms to address missing livestock or production losses.
Once a confirmed livestock depredation event occurs (injury or
death), which is compensated at 100 percent FMV up to $15,000,
livestock owners may EITHER apply for missing calf, yearling, or
sheep losses through a basic compensation ratio (i.e., number of
calves, yearlings, or sheep compensated per confirmed depredation
as defined by Commission regulation) OR apply for itemized production losses by providing specific baseline documentation, to
claim missing calves, yearlings, or sheep losses, decreased cattle and
sheep-weights, decreased cattle and sheep conception rates and additional losses. Such claims will be decided on a case-by-case basis.
This allows livestock owners to choose whether to pursue a more
simplified process (basic compensation ratio) versus one that will require additional documentation to support their claim (itemized
production losses). Based on documentation they provide as part of
the claim, it also allows livestock owners who sustain damage
amounts greater than what is covered by the simple compensation
ratio to seek production loss compensation. For each claim submitted, the livestock owner has the option to choose between the simple
compensation ratio OR itemization, but may not do both.
Colorado Parks and Wildlife

�Base Compensation:
For each confirmed wolf depredation that occurs to any livestock
enumerated in CRS 33-2-105.8(5)(c), that livestock owner will be eligible for 100 percent FMV compensation consistent with CPW
Chapter 17 Regulation #1742.B. After a confirmed depredation of
cattle or sheep, the livestock owner can choose between options 1 or
2, detailed below, but cannot do both.
Option 1, Basic Compensation Ratio:
Due to the nature of wolf-livestock depredations in areas where
topography and vegetation would create difficulties in finding livestock carcasses, CPW’s compensation plan will allow livestock owners to be compensated for missing calves, yearlings, and all classes of
sheep via a simple compensation ratio after or concurrent with a
confirmed wolf-livestock interaction resulting in livestock injury or
death. In this plan, a compensation ratio recognizes that for every
confirmed wolf depredation, it is possible that up to 7 additional
calves or sheep could be missing as a result of wolves and not be
found by a livestock owner. Additionally, the Parks and Wildlife
Commission directed that yearling cattle would also be eligible for a
compensation ratio.
For livestock owners who choose the basic compensation ratio option (this option is only applicable for calves, yearlings, and all
classes of sheep) the following apply:
• Missing livestock claimed for compensation ratio must be
calves, yearlings, or sheep; other livestock (enumerated in
CRS 33-2-105.8(5)(c)), herding, and guard animals do not
qualify for compensation ratio.
• Missing calves, yearlings, and sheep can be claimed if two
conditions are met:
° 1) Livestock owners must have a confirmed depredation event (injury or death) due to wolves to qualify
for the compensation ratio.
■ Missing animals must be from the same band or
flock of sheep, herd of cattle, or same private parcel of land where the confirmed depredation
event occurred.
■ For each damage claim submitted, a livestock
owner must have at least one confirmed depredation event.
° 2) The livestock owner must reasonably believe that
livestock reported as missing were lost to wolves and
not to other predators (i.e., bears, lions, or coyotes),
disease, or other factors.
■ Example: CPW confirms one calf was depredated
by wolves and the livestock owner reasonably believes three additional calves are missing (and can
be documented as missing by the livestock
owner).
• Livestock owner is eligible to receive 100 percent FMV compensation for the confirmed calf that was depredated and 100
percent FMV compensation for the three claimed missing
calves.
• 100 percent FMV X 4 = compensation amount.
• Under no circumstances can the number of missing calves,
yearlings or sheep claimed for compensation exceed the actual number of documented livestock missing.
Colorado Wolf Restoration and Management Plan

• CPW investigators will consider the role of topography/vegetation in determining eligibility for missing livestock. In general, the compensation ratios will only apply in larger, open
range grazing situations where locating carcasses is more difficult due to geographic and topographic factors.
• Conflict minimization techniques are not a requirement for
damage compensation, however:
° A two-tiered compensation ratio for missing calves,
yearlings, and sheep incentivizes the use of conflict
minimization, with the higher tier (up to seven missing calves or sheep may be claimed for every one confirmed wolf depredation: a 7:1 ratio, or up to 1.25
missing yearlings may be claimed for every one confirmed wolf depredation: a 1.25:1 ratio) applied when
a livestock owner uses conflict minimization techniques and the lower tier (up to five missing calves or
sheep may be claimed for every one confirmed wolf
depredation: a 5:1 ratio, or up to 1 missing yearling
may be claimed for every one confirmed wolf depredation: a 1:1 ratio) if conflict minimization techniques/methods are not used.
° Any livestock owner claiming eligibility for the 7:1
ratio (calves or sheep) or 1.25:1 ratio (yearlings) will
bear the burden of proving that conflict minimization
techniques are implemented.
■ Example: CPW confirms one calf was depredated
by wolves and the livestock owner reasonably believes seven additional calves are missing (and
can be documented as missing by the livestock
owner).
• If the landowner does use conflict minimization techniques:
° Eligible for the confirmed calf, plus the
seven missing calves
° 100 percent FMV X 8 = compensation
amount.
• If the landowner does not use conflict minimization techniques:
° Eligible for the confirmed calf plus five of
the seven missing calves.
° 100 percent FMV X 6 = compensation
amount.
• Conflict minimization techniques/methods include, but are
not limited to guard/herding dogs, sheepherders/range riders,
fladry, carcass management, and other lawful gray wolf hazing techniques enumerated in Commission regulation W10.
• Compensation ratios described above are also designed to account for some indirect production losses that could be incurred.
Option 2, Itemized Production Losses:
Economic losses other than direct loss of animals and missing
livestock can impact livestock owners. These production losses
could include decreased weight gains (i.e., weaning weights), decreased conception rates and other indirect losses. For livestock
owners who have had a confirmed wolf-livestock interaction resulting in livestock injury or death, and choose to itemize production
losses, the following apply:
• Livestock owners must have a confirmed depredation event
(death or injury) due to wolves to qualify for itemized pro33

�duction losses and missing livestock.
° Missing calves, yearlings, or sheep claimed as missing
must be from the same band, flock, or herd, or same
private parcel of land where the confirmed depredation event occurred.
° For each damage claim submitted, a livestock owner
must have at least one confirmed depredation event.
• Livestock (enumerated in CRS 33-2-105.8(5)(c) C.R.S.),
herding, and guard animals are eligible for compensation at
100 percent FMV after confirmation.
• Eligibility for missing livestock is limited to calves, yearlings,
and all classes of sheep. The livestock owner must reasonably
believe that missing livestock reported were lost to wolves
and not to other predators (i.e., bears, lions, or coyotes), disease, or other factors (and can be documented as missing by
the livestock owner).
• Under no circumstances can the number of missing livestock
claimed for compensation exceed the actual number of documented livestock missing.
• CPW staff will consider the role of topography/vegetation in
determining eligibility for missing calves, yearlings, and
sheep. In general, missing livestock can only be claimed in
larger, open range grazing situations where locating carcasses
is more difficult due to environmental factors.
• Conflict minimization techniques are not a requirement for
missing livestock or itemized production losses. However,
CPW will encourage livestock owners to employ conflict
minimization techniques to reduce further depredation.
• Conflict minimization techniques include, but are not limited
to guard/herding dogs, sheepherders/range riders, fladry, carcass management, and other lawful gray wolf hazing techniques enumerated in CPW Chapter W-10 regulations.
For livestock owners who choose to itemize production losses
claiming missing livestock the following apply (this option is only
applicable for calves, yearlings, and all classes of sheep):
• Missing calves, yearlings, and sheep can be claimed if two
conditions are met:
° 1) Livestock owners must have a confirmed depredation event (injury or death) due to wolves to qualify
for the itemized production losses.
° 2) The livestock owner must reasonably believe that
livestock reported as missing were lost to wolves and
not to other predators (i.e., bears, lions, or coyotes),
disease, or other factors.
• For missing calves, yearlings, and all classes of sheep, a livestock owner must submit the following information, included
but not limited to:
° Tangible evidence (photos, scat, tracks, etc.) that
wolves were present in the area where livestock are
missing.
° Baseline death loss (predators, poisoning, disease, etc.)
with percentages over a minimum of 3 years (preceding wolf presence in the area) using production records.
° A self-certification or documentation (e.g., ranch re34

cords) for the current year that demonstrate vaccination status.
° Written records to justify current year losses will be
provided to CPW with the following information:
■ The number of livestock (head counts) at the beginning of the grazing season and at the end of
the grazing season.
■ The number of animals that died as a result of
other predators (bears, lions, or coyotes), disease,
or other factors during the grazing season.
• Eligibility for missing calves, yearlings, and all age classes of
sheep is limited to losses above the previous 3-year baseline
death loss and cannot exceed the actual number of documented livestock missing.
• Livestock owners who cannot provide this written documentation described above are not eligible to claim missing animals under Option 2.
For decreased weight gains (only applicable for sheep and cattle), a
livestock owner must submit the following information, including,
but not limited to:
• Baseline weights over a minimum of 3 years (pre-wolf presence) along with current year weights (i.e., weight tickets,
production records, or sales records).
• To qualify, documentation must show that weights of cattle or
sheep have decreased below the pre-wolf 3-year average
weights.
• Livestock owners must provide documentation for average
3-year (pre-wolves) weights to qualify for decreased weight
gains.
For decreased conception rates, a livestock owner must submit the
following information, including, but not limited to:
• Baseline conception rates over a minimum of 3 years (prewolf presence) along with current year rates (i.e., production
records);
• A self-certification or ranch records with body condition
scores and pregnancy rate information of livestock and a
statement from the livestock owner affirming no known issues existed;
• Documentation must show a decrease in annual conception
rates below the pre-wolf average 3-year rate to qualify for decreased conception rate compensation;
• Livestock owners must provide documentation for average
3-year (pre-wolves) conception rates to qualify for conception
rate losses.
Additional losses can be considered on a case-by-case basis by
CPW and CPW will consider the role of drought and other environmental factors when evaluating context specific eligibility.

Monitoring, Ungulate Management, Research, and Reporting
State statute requires that this plan “must comply with 33-2-105.7 (2), (3), and (4)” (CRS 33-2-105.8 (3)
(a). The reference to 33-2-105.7 compels CPW to provide in a report (this Plan) information on the economic impact of a reintroduction (see Chapter 2), the probable survival rates of the introduced animals,
impacts should the introduction not take place, and an assessment on the impairment of private land or
beneficial use of water (see Chapter 5). Annual reporting requirements are also specified in 33-2-105.7 (4).

Wolf Population Monitoring
Following reintroduction, wolf populations will be monitored to
estimate annual population size and trends. All wolves that are released as part of the reintroduction will be equipped with GPS collars with VHF capability. As packs establish, CPW intends to collar
at least one member of each pack with emphasis on breeding adults.
In Phases 1 and 2, the number of wolves collared will be determined
by budgetary or logistical constraints and wolf health/safety. As the
wolf population grows, it will not be possible to have a collar on
every wolf.
Our monitoring goal is to maintain two functional collars in each
pack, although this may not be possible in all scenarios. Other pack
members may be collared to the extent feasible and depending on
circumstances or pack-specific monitoring needs. As the population
grows and disperses, it will become increasingly challenging to
maintain one collar in every pack. While not all packs will be expected to have collared wolves, managers will consider the proximity
to livestock and history of wolf-livestock conflict when prioritizing
collaring efforts.

This chapter addresses those remaining responsibilities.
A comprehensive population monitoring program is an essential
part of the wolf conservation and management program and will be
conducted throughout the implementation of this Plan. CPW will
have primary responsibility for monitoring wolves, but collaboration
with tribes, other state, and federal agencies, colleges and universities,
landowners, local governments, and the public will be necessary for a
successful monitoring program. This coordination will be especially
important when monitoring animals located on or near federal, tribal,
and private lands, and along state borders. CPW will work with
USFWS to coordinate monitoring activities while the species remains
federally listed as threatened or endangered under the ESA.
Whereas monitoring is an effort of systematic observation/measurement to assess population status and trends, research is an effort
to test theory and use data to examine the efficacy of wildlife management techniques (or tools). Both are important for wolf management. Wolf research in Colorado will provide data that can be
interpreted and used to inform management decisions. Research
pertinent to wolf management in Colorado takes both socio-political and ecological environments into consideration.
Ongoing and future monitoring and research efforts are dependent upon the ability to secure future funding and adequate staffing.
CPW anticipates that some of these activities will be conducted in
collaboration with other state and federal agencies, colleges and universities, and other relevant entities.
Future research priorities for CPW will examine both social and
biological responses from having wolves in the state. As with all
CPW research, studies will be designed to provide meaningful data
and information to inform future management. Potential research
areas are described in the following sections.

In addition to standard annual capture and collaring efforts, collars may be deployed in certain locations for specific monitoring or
research purposes (e.g., colonization of vacant territories). Further,
radio telemetry will also be employed in situations not specifically
related to population monitoring, such as select situations of livestock depredation or other wolf-human conflict. Information from
radio tracking and other survey methods will be used to determine
ecological and biological characteristics of each pack, such as habitat
use, prey selection, locations of den and rendezvous sites, in situ recruitment, survival, and mortality.
Besides collars, a variety of other monitoring tools are at the disposal of CPW biologists. Each is suited for different purposes and
the deployment of these techniques will be done in a manner that
will efficiently and effectively address the monitoring questions
being posed. Non-invasive techniques such as winter track counts,
aerial surveys, hair sampling, scat collection, howling surveys, trail
cameras, and observations by field personnel and the general public
may be used for basic population and distribution data collection
(Fuller and Sampson 1988; Boitani 2003; Patterson et al., 2004; Ausband et al., 2009; Ausband et al., 2010, Stenglein et al., 2010a; Stenglein et al., 2010b; Ausband et al., 2011).
In addition to these tools, CPW will also use other scientifically
accepted methods for estimating the number of wolves in Colorado,
Colorado Parks and Wildlife

�particularly as the population grows (e.g., Conroy et al., 2008; Mitchell et al., 2008, 2010; Stauffer et al., 2021).
Public reports of suspected wolf observations are also valuable. In
fact, it was an anonymous member of the public that informed CPW
of the presence of the female wolf known now as F1084 that produced the first litter of wolves in Colorado in recent history. The
public will continue to be encouraged to submit reports of wolf activity and sightings. Outreach will be conducted to encourage the
public to provide credible wolf sighting reports. Information on wolf
identification and where to report sightings will be included in CPW
publications and on the agency’s webpage (https://cpw.state.co.us/
learn/Pages/Wolf-Sighting-Form.aspx).
Each monitoring protocol has its own advantages and disadvantages. No single method will be suited to all packs. CPW will consider any and all population monitoring methods, including new
methods as they are developed.
As wolf populations have grown in other states, monitoring costs
have substantially increased. Consequently, rather than trying to
count every wolf, western states are turning to methods for statistically estimating populations. CPW will adopt this same paradigm as
the Colorado wolf population grows in size and distribution. In
Phase 3, the wolf population will generally be monitored through a
statistically derived estimate of population size, although minimum
counts will continue to be enumerated as a necessary component of
the statistical methodology. Biologists will begin the transition from
minimum counts to statistically derived population estimates during
Phase 2.
Research: Wolf ecology in Colorado.
Important research topics for CPW staff and partner research entities may include, but are not limited to, habitat colonization and
use, population dynamics, and social structure of wolves and wolf
packs in Colorado. In terms of overall conservation of wolves, one
key need is validation of habitat suitability models in Colorado using
empirical data. CPW has applied existing habitat models for wolves
in the state, but the results are speculative in the absence of actual
Colorado data. Research questions associated with wolf reestablishment in Colorado will be prioritized based on funding support and
relevance to conservation and management needs, which will evolve
and become more clear following reintroduction and the rate at
which subsequent population growth and expansion occurs.
Wolf Mortality Monitoring
Because CPW will be required to institute and maintain an active
program of wolf population monitoring statewide, it is imperative
the agency be promptly notified of all forms of mortality, regardless
of location and legal status of wolves. Infectious disease, starvation,
and intraspecific strife are the primary causes of wolf mortality in
unexploited populations. Intensive monitoring and research activities will be the primary means of identifying both human-related
and natural mortality factors for wolves. An important component
of Colorado’s wolf management program will be to adequately monitor and manage human-caused mortality. Research suggests that
annual mortality rates of 22 to &gt;50 percent may suppress wolf population growth (Keith 1983, Ballard et al., 1987, Fuller 1989, Fuller et
al., 2003, Creel and Rotella 2010). All forms of wolf mortality will be
considered when making management decisions.
Although lethal control is a necessary tool for reducing wolf depredation on livestock, excessive levels of lethal removal can inhibit
the recovery of wolf populations. CPW will therefore monitor and, if
necessary, adjust the extent of lethal removals (including mortalities
from lethal take of wolves “in the act” of attacking livestock) to meet
both conservation and management needs. Consideration should
also be given to minimizing lethal control around or between any
Colorado Wolf Restoration and Management Plan

core recovery areas that are identified, especially during the denning
and pup rearing periods (April to September).
Education and regulation will be implemented to minimize the
unintentional take of wolves by coyote hunters, or trappers using live
traps. Information and education efforts will be needed to inform
hunters about the presence of wolves in occupied areas of the state.
CPW will use hunting and fishing regulation pamphlets and other
means to provide educational messages and identification materials
about wolves, including how to avoid accidental take during legal
hunting seasons for other species. These programs will assist hunters
in becoming proficient at distinguishing wolves from coyotes, and
trappers in learning methods for avoiding accidental capture of
wolves and what to do if a wolf is inadvertently caught. Incidental
trapping of wolves is not expected to occur because trappers in Colorado are only allowed to use box and cage traps and wolves are
wary to these trapping methods. Education materials will be presented to individuals who are provided 30-day exemption permits.
The illegal take of wolves will be expeditiously and thoroughly investigated. While wolves are federally listed as threatened or endangered in Colorado, the USFWS Office of Law Enforcement is the
lead investigative agency; when they are federally delisted, CPW will
be the lead, unless otherwise outlined in an MOU between the agencies.
Wolves that were reintroduced to Idaho and Yellowstone National
Park had relatively high survival rates. In Idaho, 30 of the 35 animals
survived through the second year of reintroductions (Bangs and
Fritts 1996). In Yellowstone, 22 of the 31 animals survived through
the second year of reintroductions (Bangs and Fritts 1996). Causes
of mortality included interspecific conflict, illegally shot, wolf control action, struck by vehicle. Idaho had 85 percent survival and Yellowstone releases had 70 percent survival. It is anticipated that the
survival rates will be within that range for the first years of reintroduction in Colorado.
Research: Wolf-livestock interactions.
The effects of wolves on livestock and methods to reduce
wolf-livestock conflict are important areas of research throughout
the West. Ongoing research aims to determine the efficacy of existing practices to reduce wolf-livestock conflict such as livestock husbandry practices, non-lethal deterrents, and lethal control. Research
on indirect effects of wolves on livestock (e.g., weight loss, decreased
pregnancy rates) is largely inconclusive and highly specific to study
sites. Compensation programs benefit from research focusing on direct mortality rates of livestock due to predators, detection of predator-killed livestock carcasses, and quantification of losses from
indirect effects on livestock production. All of these may be considered for research in Colorado.
Efforts in Colorado will require funding and a coordinated approach among livestock owners, resource agencies, researchers, and
NGOs to design, deploy, and maintain research projects. As more is
learned about wolf-livestock interactions in Colorado, collaboration
will be needed to make necessary changes to reduce future wolf-livestock conflicts and share this information with affected publics.
Wolf Health Monitoring
Wolf health monitoring will follow established CPW wildlife
health monitoring practices including both active and passive disease surveillance. During live capture operations, animals will undergo a brief physical exam to assess body condition, estimate age,
and survey for external parasites. Blood and other biological samples
will be collected from live-captured animals and submitted to the
CPW Wildlife Health Laboratory. Disease diagnostics will be tailored to the individual based on known health concerns in the population, research objectives, and disease surveillance priorities. The
37

�CPW Wildlife Health Laboratory will maintain banked serum, tissue, and other biological samples.
Carcasses from wolf mortalities that are retrieved will be submitted to the CPW Wildlife Health Laboratory. CPW pathologists and
veterinarians will tailor post-mortem diagnostics to the individual
based on animal history, gross necropsy findings, research objectives, and disease surveillance priorities. As baseline data accumulate, the value of routine necropsies may diminish, and the
submission of carcasses will be reduced to special forensics or disease-related cases.
In the unlikely event of human injury or death during a wolf-human encounter, the wolf or wolves will be destroyed and the carcasses forwarded to the CPW Wildlife Health Laboratory. Testing for
zoonotic diseases of concern will be coordinated with the Colorado
Department of Public Health and Environment (CDPHE). If a wolf
bites a person during a capture and handling incident, CPW will follow recommendations from CDPHE to protect human health.
Ungulate Population Monitoring
The effects of predators on prey populations were one of the greatest concerns expressed by the public about wolf recovery in the
northern Rockies (USFWS 1987, 1994a, b). Recent community engagement in Colorado suggests that those same concerns occur
across much of the state, particularly on the Western Slope (Keystone 2021).
CPW conducts surveys of annual production, survival, and harvest of ungulate populations. These data are used to estimate population abundance and trends, and to make recommendations for
hunting seasons and other management actions as described in
Chapter 2. Intensive ungulate monitoring has already begun prior to
reintroduction and may expand into additional areas as wolf populations grow and distribution expands.
Elk Monitoring
In addition to elk inventory and monitoring described in Chapter
2, in 2022 CPW initiated three Elk Monitoring Areas. This is a sentinel herd approach, modeled after the five Intensive Mule Deer Monitoring Areas CPW has maintained for 22 years to inform mule deer
management. These study areas are designed to increase the amount
of data on elk survival, movement, habitat use, and causes of mortality prior to, and after, wolf reintroduction.
CPW will evaluate the behavioral responses of elk to wolves
by monitoring elk distribution and movement.

These three new Elk Monitoring Areas will complement the existing three elk research study areas resulting in six elk sentinel herds
representing different elk habitat types, calf/cow ratios, and geographic locations. Research study areas were selected to investigate
causes of low elk calf/cow ratios (i.e., elk calf recruitment) by comparing low elk calf/cow ratio areas with high elk calf/cow ratio reference areas. The Elk Monitoring Areas will add herds with average
elk calf ratios (40-55 calves/100 cows) to the sample and will be located in the center of the state. Having pre-wolf reintroduction survival and cause of mortality information will be important when
estimating the effects wolves have on elk population dynamics and
distribution.
The purpose and information objectives of Elk Monitoring Areas
are as follows:
• Estimate factors affecting elk survival rates and calf recruitment, including wolves, other predators, harvest, habitat
quality, etc.
• Document cause-specific mortality on elk pre- and post-wolf
colonization.
• Evaluate the behavioral responses of elk to wolves by monitoring elk distribution and movements. For example, do elk
use refuge areas more or less with wolves on the landscape?
Do elk move to refuge areas earlier or later in the year, and do
they use the same seasonal ranges as they did prior to wolf reestablishment?
• Improve modeled elk population estimates. To estimate population size, elk population models rely heavily on annual
survival rates of adults, winter calf survival rates, and appropriately delineated DAU boundaries. CPW will need more
accurate and precise elk population estimates to answer questions and manage both elk and wolves. CPW will use individual marks on elk collars to estimate population size and
directly assess abundance and improve modeled population
estimates.
Deer Monitoring
Deer populations will continue to be monitored as described in
Chapter 2.
Moose Monitoring
Moose are notoriously difficult to enumerate because they exist at
lower density, don’t form large groups in the open during winter, and
rarely flee from helicopters as much as deer and elk (inhibiting detection). Only North Park has consistent moose inventory flights
and population models using similar methods described for deer
and elk.
CPW initiated two new moose projects in 2022. A project on
Grand Mesa will use GPS collars in conjunction with infrared aerial
technology to estimate moose detection probability, density, and
population size. In Steamboat Springs, a camera grid project will estimate moose density to aid in determining moose distribution and
population estimation.

Research: Wolf interactions with ungulates, other wildlife, and
vegetation.
Ungulate monitoring is a priority independent of this Plan, but in
relation to understanding wolf effects, efforts will need to be expanded to include information such as moose, deer, and elk abundance and distribution, habitat use and selection, pregnancy and
birth rates, juvenile/adult female ratios, and cause-specific mortality

�rates in relation to the presence of wolves. Additionally, if and how
wolves impact ungulate disease dynamics will be of research and
management interest.
Surveys and monitoring to assess distribution and abundance of
existing predators in Colorado will need to be applied to determine
what effect wolves have on the dynamics or behavior of these species. Generating abundance estimates for many species is challenging and expensive, and therefore may not be realistic for all predator
species. Understanding the effects of multiple predators on ungulate
populations, including rates of additive and compensatory mortality,
may be important for predator and ungulate management. Further,
assessments of habitat change post-reintroduction may also be of interest.
Social Science Monitoring
The social dynamics of wolf management are inherently complex.
People’s beliefs and attitudes about wolves and wolf management
elicit strong emotional and cognitive responses which are often informed by deeply held values and connected to personal and professional (even group) identities (Bright and Manfredo, 2008; Slagle et
al. 2012; Lute and Gore, 2014; Straka et al., 2020). These attributes
can influence human behavior in a variety of ways. As a result, it is
critical to understand the range of values and preferences people
have about wolf management.
Conservation social science — which includes a wide range of disciplines spanning psychology, anthropology, economics, and others
— can provide important insights about people’s preferences for and
perceptions about wolf management and the extent to which these
influence human behavior or support for wolf restoration in Colorado (Bennet et al., 2017). Social science data can be used by wildlife
managers and other decision makers to develop long-term strategies
that minimize social conflict, create opportunities for humans and
wolves to cohabitate in Colorado and increase social learning and
social trust.
In 2021, CPW and faculty from Colorado State University began a
longitudinal study about stakeholders’ perspectives regarding wolf
restoration processes and outcomes. Specifically, this study is examining potential changes in different groups’ attitudes about social
conflict, social learning, social trust, and acceptability of management alternatives over time. These data will help inform and improve future stakeholder engagement planning and public outreach
efforts while also providing important insights into how and why
CPW’s wolf restoration planning process achieved various social
outcomes.

ing the efficacy of messaging and trust in communication efforts (e.g., “messenger matters”);
• Social-ecological research, e.g., potential impact of wolves on
ungulate populations, license sales, and stakeholder perceptions about these relationships.
Reporting
CPW is required to produce an annual report for a reintroduced
species as described in CRS 33-2-105.7. The report will be prepared
annually for each of the 5 years post-reintroduction. The first report
will be written after the first year of reintroductions. Preliminary research results will not be reported on until peer review and publication has been completed.
Annual wolf reports will address the statutory requirements and
include information on the status of the reintroduction effort, a report on the estimated survival rates of the reintroduced wolves and
their progeny; an assessment of the survival rates with respect to initial expectations, plus the recovery goals and anticipated timelines of
the wolf recovery program. The annual reports will be available to
the public on the CPW agency website and provided to the Commission and Colorado General Assembly. Upon request, the Commission, Legislature, and other partners will be briefed and updated
regarding the Plan’s implementation.
CPW expects to publish the annual report covering the biological
year from April 1-March 31. This corresponds with the “biological
year” of the wolf, and will allow reporting on wolf production, dispersals, pack formation, etc.
Following the conclusion of the initial release, CPW staff will provide updates on the plan at least annually to the Commission on the
plan’s progress, but staff can be asked to provide an update at any
time interval as there are new developments. A formal review of the
progress of the plan will be scheduled five years after the completion
of the reintroduction efforts.

Research: Social Science
Potential areas of future social science research to inform wolf
management in Colorado are expected to fall into the following categories:
• Stakeholder/public values and attitudes about wolves, wolf
management, and human-wolf interaction, e.g., social acceptability and how it changes over time;

• Economic research, e.g., examining impacts of wolves on
tourism, the outdoor recreation industry, and outfitters/
guides/livestock owners’ quality of life;

In 2014, CPW completed the West
Slope Mule Deer Strategy, which
guides management decisions to help
rebuild our mule deer populations.

• Experiences and satisfaction with wolf compensation and
preventative measures programs, e.g., tracking implementation/use of preventative tools and measuring perceptions
about efficacy over time (across stakeholder groups);

• Evaluation of CPW’s education/outreach efforts, e.g., examinColorado Wolf Restoration and Management Plan

�Chapter 8:

Education, Outreach and Agency Coordination
A well-informed public is essential to gray wolf conservation and some authorities consider outreach efforts to be the highest priority in restoring the species (Fritts et al., 1995, 2003). It is crucial that wolves and
wolf management issues be portrayed in an objective and unbiased manner, and that the public receives
accurate information on the species. Conflicts with wolves and the solutions and compromises needed to
resolve those conflicts must be discussed fairly (Fritts et al., 2003).

Education and Outreach
Colorado’s residents need access to factual information about
wolves and wolf management from wildlife managers; and wildlife
managers need information from the public on sightings, depredation events, wolf behavior, and public opinions to effectively manage
wolves in the state. With this two-way communication, implementation of the Plan will have a higher probability of success and both
managers and the public will have the necessary information to
make conservation and management decisions to achieve Plan objectives. Two-way communication depends on a public that is informed about wolves and ongoing management activities and
agency staff who are well informed and willing to listen to the real
and perceived concerns of residents about wolves. Strengthening internal knowledge about wolves among agency staff will lead to more
effective external communication efforts. This will include regular
updates to staff on significant wolf activity, Plan implementation,
field activities, research findings, and management responses using
Director’s messages, internal newsletter, and annual training days.
As CPW assumes management of wolves, it will be necessary to
identify and address a broad array of questions concerning wolf biology, ecology, and management. CPW has published information on
its website (https://cpw.state.co.us/learn/Pages/Wolves-Stay-Informed.aspx) that answers many of these questions. Because wolf
management will be closely scrutinized, CPW will seek a balanced
management approach that acknowledges the complexity of the political, social, and environmental factors associated with wolves and
their management.
The objectives of the information and education section of this
Plan include:
• Increase public awareness of wolves, their recovery, and state
management authority after federal delisting;
• Increase awareness of wolf status in Colorado, the state delisting process, and state downlisting and delisting milestones;
40

• Increase awareness of the array of wolf management tools
CPW will employ as situations arise;
• Increase awareness of wolf biology and ecology, impacts to
prey populations, livestock depredation, and public safety;
• Assist the agricultural community in informing their stakeholders of the importance of assisting CPW with data collection.

A wolf den is studied to gather information on habitat use.
CPW staff will lead education and outreach initiatives, providing
information to the public about ongoing wolf conservation and
management activities through a wolf communication and outreach
plan for Colorado. The program will include programs and materials
appropriate for key audiences. Subject matter experts will provide information on wolf status, biology, habitat use, ecological role, and
place as a part of Colorado’s natural heritage.
Through the print and electronic media, the appropriate sections
of the Information and Education Branch will produce news releases, video productions, and local and mass media articles for
statewide distribution. These products will be used to convey factual
information regarding wolf management, policy, actions, and issues
of public concern, as well as answers to questions most likely to be
asked about wolf management. The Plan will also be posted on
CPW’s website for the public to read.
Informative articles will continue to be published in CPW’s variColorado Parks and Wildlife

Extensive public outreach was conducted before and during wolf
recovery in Montana, Idaho, and Wyoming, using a broad mix of
approaches (Fritts et al., 1995). These efforts conveyed a factual and
balanced view of wolves, stressed the differences between wolves and
other canids, described the legal and biological rationale for recovery, pointed out that some wolf control must accompany recovery,
and emphasized that very few restrictions on use of public lands are
necessary for wolf recovery. The success of wolf recovery in these
states is, at least in part, due to these information and education efforts.
The Commission will periodically obtain public input to update
this plan, when circumstances dictate that that would be necessary
and beneficial.

�ous communications outlets. These articles focus on wolf biology,
identification, behavior, population status, and management as it relates to the audience of these publications.
Wolves will be integrated into CPW’s ongoing education and outreach. Six “target audiences” will be a high priority:
• General public
• Agricultural community
• Sportspersons and outfitters
• Wolf advocates
• Outdoor recreationists
• Local and Municipal decision makers
Information and education materials will be developed for target
audiences to:
• Address concerns over wolf-livestock conflicts, including
training methods to prevent wolf-livestock conflicts, response
options to protect livestock, how to report suspected wolf
depredations, and, as appropriate, provide ongoing wolf
monitoring information to livestock owners;

• Educate hunters, people viewing ungulates, and others and
addressing concerns over wolf-ungulate interactions;
• Educate and inform K-12 classrooms, environmental learning centers, and other appropriate outlets.
Coordination with Other Governments, Agencies,
and Organizations
CPW will continue to coordinate with other agencies and organizations to achieve wolf conservation and management objectives.
This will be accomplished by continuing to use the expertise of the
U.S. Fish and Wildlife Service (USFWS), the U.S. Department of Agriculture’s Wildlife Services Program Animal Plant Inspection Service (APHIS), U.S. Forest Service (USFS), Bureau of Land
Management (BLM), Colorado Department of Agriculture (CDA),
Colorado Department of Education (CDE), and other state agencies,
tribal governments, and private sector professionals. Coordination
with other state land management agencies, such as the State Land
Board, Colorado State Forest Service, and others, will occur as
needed. Further, CPW will engage non-governmental stakeholder
organizations for input regarding wolf management in Colorado.
CPW will inform public and private land managers of general wolf
presence on their respective lands as needed to facilitate informed
management decisions. This information will not be “real-time” information or even necessarily recent location information (especially
on private land where data sharing is restricted). As resources permit
CPW staff will inform county boards of government of wolf-related
activities as needed and requested.

Colorado Wolf Restoration and Management Plan

41

�Chapter 9:
Funding

Within this Plan, CPW presents strategies to implement conservation and management actions for
wolves in Colorado. This Plan proposes programs that do not currently exist; a restoration program to reestablish wolves to the state, monitoring programs to monitor both wolf and prey populations, and a mitigation and compensation program to mitigate impacts of wolf depredation on livestock. Successful
implementation of the Plan will require additional staff, financial resources, and possibly legislative and
regulatory updates to support those programs. It is recognized that current resources available to CPW for
management of nongame wildlife such as wolves are limited; however, taking on the additional responsibilities for conserving and managing wolves is an agency priority based on the mandates in CRS 33-2105.8. At the same time, CPW must also be mindful that existing programs, funding, staffing, and
resources are not sufficient to take on the new and significant responsibilities of reintroducing and managing wolves without sacrificing some other important threatened and endangered species efforts as well as
other wildlife management responsibilities the agency currently conducts.
To adequately manage wolves, it has been necessary to augment
resources for state wildlife agencies in every other western state
where wolves have been reestablished. To fully implement the elements and strategies of the Plan, a formal wolf conservation program consisting of staff, budget, equipment and other resources will
need to be developed within CPW as funding and additional staffing
are made available. Throughout all aspects of wolf restoration and
management (preventative measures, monitoring, research, education, outreach) it will be critical to evaluate staffing needs and associated budget considerations. Further, development of a funding
stream that seeks legislative, NGO, and partner financial support as
necessary will be critical for this program to be successful. The establishment of mechanisms to comprehensively track wolf program
expenditures, including staff time, will be important for reporting
and budgeting purposes.
Funding for a wolf conservation program will be developed in accordance with these basic tenets:
• Long-term funding will be necessary for a variety of needs related to wolf restoration and management, including but not
limited to: staff capacity, reintroduction logistics, management and conflict minimization materials and activities, depredation compensation, monitoring and research, and
education and outreach.

• Consider all sources and opportunities for funding, including
annual and multiyear public sources, grants, and NGOs and
private organizations.
• Consider development of a capital campaign and endowment
fund or funds. If an external fund is established, provide clarity and assurance on what funds will be provided to CPW
over time and for what purposes.
• Consider flexible funding needs as well as program-specific
opportunities.
° Unrestricted funding provides CPW with the greatest
flexibility to provide for adaptability of the program
over time to assess and address needs.
• Separate funds for compensation and conflict minimization
(nonlethal or lethal) can provide opportunities for specific
kinds of funding sources. For example, federal livestock
demonstration funds can be used for livestock loss compensation, and APHIS nonlethal funding as well as private donations could support conflict minimization.

• Encouragement of external funding contributions early or
prior to reintroduction while interest is high, so that it is
available when needed in both the short- and long-term.
• Consider opportunities for collaborative funding strategies,
with prioritization of funds for CPW complemented by additional, independent funding opportunities.

• While there are many potential opportunities, funding
sources can be complex and challenging to secure, with competition for a variety of priorities.

• Funding sources should ideally be additive to existing funding streams, and provide longevity.

�Conclusion
This Plan describes an adaptive management system for wolves in
Colorado. CPW views the adaptive management approach as an important underpinning of the monitoring and evaluation of the Plan.
By definition, an adaptive system incorporates monitoring and evaluation components as an ongoing effort within the management
program. Management is thus refined and improved through time
as information and experience accumulate. CPW will evaluate new
information as it becomes available and incorporate it into wolf
management.
An adaptive system will help address and evaluate the wolf-specific components of this Plan. For example, is a viable population of
wolves being maintained? Are the monitoring protocols adequate to
assess wolf population trends or other biological parameters of interest? Are adequate populations of prey species being maintained to
sustain a wolf population and provide sportspeople with the opportunity to hunt a wide variety of species under a wide variety of circumstances in a sustainable manner? The advantage of managing
adaptively is that, by definition, it provides a framework and a process for decision-making, as well as the mechanism to monitor and
evaluate the outcomes.
Equally important components of any wolf management program

are the social factors that shape public tolerance for wolves and their
satisfaction with how conflicts are resolved. For example, is the management program adequately and efficiently addressing wolf-livestock conflicts? Is public safety assured? Has the presence of wolves
resulted in beneficial ecosystem responses? These are important
management program components for which ongoing evaluation is
critical. CPW anticipates that Colorado residents will readily identify
real or perceived problems or shortcomings of the wolf management
program on these topics and others.
The challenge for CPW will be to discern between earnest differences of opinion in preferred management direction and substantive
shortcomings of the program. Wolf management in Colorado will
take place within a complex biological, social, economic, and political environment. Difficult decisions will have to be made and will
sometimes be called into question by various interests. However, the
ensuing public dialogue will also help evaluate the management program and may lead to revisions. CPW, after reviewing input from
the public, wildlife professionals, coordinating states, other state and
federal agencies, etc., will modify and adapt the wolf management
program in the future to maintain a viable wolf population within a
complex environment.

negative impact), managers will work to resolve the problem using a
variety of management tools.
Intraspecific — Occurring within a species or between individuals
of the same species.
Itemized production losses — Decreased weight gains and decreased conception rates.
Lethal Management — Techniques that cause or are closely associated with the death of animals.

�About the Technical Working Group (TWG)
Colorado Parks and Wildlife (CPW) invited technical experts to serve on the Technical Working Group (TWG) to
provide and review objective, science-based information as well as provide their own knowledge and experience
at the state/federal/Tribal level to inform the development of the Colorado Wolf Restoration and Management
Plan. The TWG is composed of members who bring experience in wolf reintroduction, wolf management,
conflict minimization, depredation compensation, and other relevant topics.
Colorado Parks and Wildlife (CPW) is responsible for writing the Wolf Restoration and Management Plan. The
Parks and Wildlife Commission (PWC) serves as the decision-making body responsible for approving the Wolf
Restoration and Management Plan. The TWG serves in an advisory capacity to Colorado Parks and Wildlife,
offering non-binding input into the development of plan content. The TWG is not a decision-making body and
has no authority on wolf management policy, research, or operations.
TWG considerations and recommendations are based upon members’ knowledge and experience in biological
science and wolf management. The TWG was not charged with conducting literature reviews but rather drew
from its in-depth knowledge of literature in offering insights to inform the plan.
The TWG operates by consensus. For purposes of the TWG, consensus refers specifically to general agreement,
or lack of objection, that an option or alternative has sufficient technical merit to be recommended for
consideration by CPW. In the absence of consensus, dissenting views are documented to characterize the range
of views and/or the range of science, experience, and uncertainties on specific topics. (See Appendix D for the
TWG Charter).
The TWG met once monthly via Zoom from June 2021 to August 2022, except for May 2022 and in a joint
meeting with the Stakeholder Advisory Group (SAG) December 2021. A total of 14 meetings were held with the
TWG, inclusive of the SAG-TWG joint meeting. Meeting summaries were developed and published for each
meeting.

Cross-Cutting Themes
The following themes emerged recurrently and consistently throughout the TWG’s discussion of restoration
logistics; livestock compensation; recovery metrics and delisting and down-listing thresholds; and management
considerations.
● Building trust, maintaining relationships, setting expectations, emphasizing transparent and meaningful
outreach with stakeholders and the public, and having a consistent, frequent, and determined presence
in the field by CPW staff to establish and maintain trust are critical to achieve success in reintroduction
and management.
● Both biological/ecological and social/economic dimensions are important to inform Colorado’s wolf
reintroduction and management plan.
● Allowance of flexibility and adaptation of management both spatially and temporally is important for
successful implementation.
● Availability of a full array of management tools to minimize and respond to conflict is critical for working
with, addressing impacts to, and assisting affected communities and for providing compensation to
individual producers.
● Availability of funding and resources to implement the plan is critical.

Research and monitoring are important tools to support other aspects of reintroduction and
management.
Wolf reintroduction and management planning is inherently controversial and complex; there is no one
solution or silver bullet to meet all goals of all interested groups.
Colorado has the opportunity to learn and build from past experiences with wolf introduction in other
states as well as from its own experiences in wildlife management in developing and implementing a
plan to meet Colorado’s specific needs and context.

Summary of Recommendations on Wolf Restoration Logistics
Key takeaways are presented below. See Appendix E: Final Report on Restoration Logistics for additional
details on these topics as well as for TWG recommendations on: capture methods at source; what to do with
injured animals at source site; age ratios; color ratios; sex ratios; disease issues at sources site; what to feed
during a period of captivity; immobilization drugs to be used; where and how to hold animals prior to shipping
and upon initial arrival in Colorado; samples collected from animals; veterinarian care in captivity; disease
testing and vaccine treatment; and more details on all topics.

Capture considerations
●

●

●

●

Donor populations: The alternatives Idaho; Montana; Wyoming; Mix of Northern Rocky Mountain
States; Washington; Oregon; Great Lakes; and Mexican Wolves all have technical merit. Idaho, Montana,
Wyoming, and a Mix of these Northern Rocky Mountain (NRM) states are recommended as the
preferred donor populations, as logistical, source site jurisdiction, and other considerations allow.
Planning for all three states and keeping options open and flexible is also recommended both for the
initial donor population and for subsequent donor populations as needed. Some TWG members
recommend Wyoming as slightly preferred. If these sources are not available, Washington and Oregon
are next in preference.
Genetic considerations: The alternatives related pack members; unrelated, dispersing age animals; and
mix of packs and unrelated individuals all have technical merit, with highest preference for unrelated,
dispersing age animals; followed by preference for a mix of packs and unrelated individuals; and least
preference for selecting only related pack members.
Animal reputation: The alternatives “not known to be a depredator,” “wolves that have been around
livestock without conflict,” and “wolves that have not been present around livestock at all” all have
technical merit as factors for sourcing donors; “known depredator” has technical merit as a criterion for
exclusion from sourcing. Sourcing donor populations not known to be depredators (whether present
around livestock or not) was preferential to sourcing populations not exposed to livestock, if possible.
However, it is important to consider that most wolves overlap areas with livestock, and there is not a
way to know the degree of interaction they have had with humans. No wolf should be translocated that
has a known history of chronic depredation, and sourcing from geographic areas with chronic
depredation events should not occur.
Transportation method from source to Colorado: The alternatives air; ground; and mix all have
technical merit, with no group preference among the alternatives; each has situational relevance
according to the plan of capture and translocation. Key to success is that capture, transport, and release
should occur as quickly as possible to minimize time in captivity and stress on the animals.

�Animal handling considerations
●

Collars/marks on animals initially reintroduced into the state: Alternatives VHF; GPS; mix of VHF/GPS;
PIT tags; ear tags (perhaps temporarily when in captivity) all have technical merit; the alternative “no
collar” for animals initially reintroduced into the state does not have technical merit. It is preferred that
every released wolf has a GPS collar, with variability in durability of GPS collar types as an important
consideration. Ear tags are less preferred as compared to the other collaring/marking alternatives.

Reintroduction considerations
●

●
●

●

●

●

Reintroduction technique: Alternatives hard release; soft release; and a combination of soft and hard
release all have technical merit, with hard release preferred to soft release and to a combination of soft
and hard release. There are pros and cons to consider for both techniques; however, hard release has
greater technical merit as well as greater logistical and economic feasibility and is thus recommended by
the TWG as the preferred technique.
Time of year for reintroduction: Alternatives spring and summer do not have technical merit;
alternatives winter and fall both have technical merit; and winter is preferred over fall.
Considerations for where wolves could be released: All of the following considerations have technical
merit: land ownership; livestock presence; geographic context; prey base; likelihood of supporting
multiple packs; proximity to state border; vote results; and seasonal elk supply. Vote results have least
preference as a technical alternative to guide reintroduction location, but it is recognized that sociopolitical considerations will also be at play in selection of release area(s). A site where a wolf is released
is not expected to be necessarily where the wolf will stay.
Number of release sites (and number of release areas): The alternatives of flexibility in specific release
sites for an area with multiple release points; multiple release areas; and one release area were all
determined to have technical merit. The alternative to have flexibility in specific release sites for an area
with multiple release points is most preferred.
Pace of wolf reintroduction: All of the following alternatives have technical merit: about thirty to fortywolves reintroduced for one year (fast); about ten to fifteen wolves reintroduced per year for two to
three years (medium); about five to ten wolves reintroduced per year for three to six years (slow); and
“be flexible” (note: numbers are not concrete and are meant to suggest relative pace). The general
technical preference is for a “medium” pace, followed by a “slow” pace, and, least favorably, a “fast”
pace. It is important to be flexible and adapt the specific logistics of these paces according to conditions
of the reintroduction. It is also important to be adaptive around specific dates and numbers. The overall
goal is ultimately to establish a self-sustaining population. The goal of the initial translocation and
restoration is to introduce enough wolves at an adequate pace to establish a growing population that
can ultimately achieve a self-sustaining population. Without specifying what that might look like from a
numerical perspective and/or other indicators, there are a variety of ways (i.e., paces) that could work
to achieve a growing population. Note: discussion of this topic focused specifically on the number of
wolves actively reintroduced, not long-term population goals or management thresholds.
When to stop and/or pause reintroduction: The following alternatives all have technical merit: after
about forty animals have been moved; indication of pack establishment; indication of pack
establishment with some documented reproduction; two packs raising two pups for two consecutive
years; and a flexible approach (i.e., do releases (e.g., of thirty to forty wolves) and then pause to see
what happens) all have technical merit. The preferred option is to do ‘a bunch’ (undetermined number)
of releases (e.g., release a total of approximately thirty to forty wolves), then pause, assess, and adapt
based on whether the initial restoration phase has resulted in an adequately growing population that
will ultimately achieve a self-sustaining population.

�Summary of Technical Considerations on Compensation for Wolf Damage to
Livestock
Key takeaways are presented below. See Appendix F: Final Summary of Technical Considerations on
Compensation for Wolf Damage to Livestock for more detail.

●

Social dimensions of compensation plans: While the TWG provided feedback on technical merit on
potential compensation elements, it recognized that there are various social considerations for livestock
compensation and thus the Stakeholder Advisory Group (SAG) was charged with leading the
development of comprehensive recommendations regarding the compensation plan.
Confirmed and probable depredation: There is TWG consensus that compensation for confirmed
depredations at fair market value has technical merit. Compensation for probable depredation has
technical merit. A range of compensation amounts (50-100% of fair market value) were suggested as
having technical merit; however, lesser amounts (i.e., less than 50%) were not suggested.
Compensation ratios/multipliers: There is TWG consensus that compensation ratios for missing cattle
and sheep on public and private lands have technical merit, but there are different perspectives and
technical considerations regarding when these ratios should be triggered and how they should be
administered. TWG members generally were uncertain as to what an appropriate ratio should be.
Indirect losses: There is TWG recognition of the technical reality of indirect losses. However, there was
mixed feedback from the TWG on whether there is technical merit to compensate for indirect losses, as
many factors can contribute to indirect losses, particularly as there is not a clear or proven technical
approach for quantifying and compensating for indirect losses. Indirect losses include impacts to
pregnancy rates, weaning rates, lower weight gains due to stress or increased activity rates, future
economic losses (e.g., loss of future production or loss of investments in genetics).
Pay-for-presence: The TWG did not have clear consensus on whether or not pay-for-presence programs
have technical merit; they offered a variety of perspectives regarding feasibility, purpose, and efficacy.
CPW’s current game damage program: There are various considerations for whether and how the
current program should be evolved specifically for wolves. There is general consensus regarding the
value of consistency of process; however, there are a variety of opinions on whether there should be
differences in compensation eligibility, amount, and/or criteria. Many TWG members suggest technical
merit in consistency in using the existing program; however, the TWG also recognizes that there are
various social considerations on this topic as well that the SAG will weigh in regarding whether and how
the current program should be evolved for wolves.
Damage investigations: Conducting damage investigations via CPW and APHIS-WS has technical merit.
Investigators should have adequate training to conduct professional, consistent damage investigations.
Funding sources and administration: TWG perspectives generally support using multiple sources of
funding for compensation and other livestock interactions issues, although there were varying
perspectives on whether this is a technical issue and/or is an issue with technical merit. Consistency in
administration of funds, regardless of sources, was emphasized. Pros and cons of using other agencies as
administrators for funding and/or for other elements of the game damage program was also discussed.
Non-lethal risk reduction requirements for compensation: TWG members emphasized the importance
of encouraging non-lethal risk reduction techniques; however, there were various perspectives
regarding the technical merit and feasibility of requiring their use in order to receive damage
compensation. The TWG discussed context-specificity of non-lethal risk reduction practices and losses;
importance of maintaining flexibility rather than prescribing practices; difficulty in defining risk
reduction requirements; value in strategies to incentivize adoption and creative problem solving; and
maintenance of relationships with local producers.

Wolf Population Listing/Delisting Phased* Framework

The recovery metrics or thresholds outlined in the table below were developed through expert deliberation
of TWG members and are presented in a phased framework. While the determination of these thresholds is a
technical exercise, management actions corresponding to the phased framework should be informed by legal
and social considerations, which will be addressed largely by the Stakeholder Advisory Group (SAG).

�Notes on the framework

*Phases will be dictated by numeric and temporal wolf population thresholds described in the table. While it is
intended that state status will also correspond to these thresholds, there may be a time lag as the Parks and
Wildlife Commission undertakes the procedural process to change the state status based on population counts.
**Minimum population counts in any phase include gray wolves that have been reintroduced to Colorado and
those that have naturally migrated into the state and their progeny. Wolf population minimum counts in this
table refer to counts conducted in late winter to most accurately reflect recruitment.
***“Successive” means years in a sequence, with any number of gaps in between. Consecutive means years in a
sequence with no gaps. The rationale for using a metric of successive years is to account for potential years
when an adequate survey cannot be conducted.
****Downlisting to state threatened status may not occur until the four-successive year requirement is met in
the state endangered status (Phase 1). However, the two-successive year timeline for the Phase 2 minimum
count requirement begins when the minimum number is first met and may occur concurrently while in the
Phase 1/endangered phase. Consequently, it is possible that delisting (conclusion of Phase 2) may occur
immediately after Phase 1, should the Phase 2 requirements be met concurrently during Phase 1.

The TWG’s inclusion of Phase 4 in the above table does not indicate a TWG consensus recommendation on
whether or not Phase 4 should occur; it is intended to demonstrate that phased approaches may potentially
include a Phase 4 (classification as a game species). The TWG recognized that determination of whether to move
to game classification should consider a variety of information and perspectives and will also be informed by
legal considerations including interpretation of authorities relative to the definition of gray wolves in CRS 33-2105.8 as being a nongame species. Many TWG members support Phase 4; however, one TWG member opposed
Phase 4 and also suggested that the Phase 4 column is redundant with information already described in Phase 3.

Conflict-centered management vs. objective-based management: Wolf management should focus on
management of conflict, with consideration of the social factors that accompany an impact-based
management approach. Lessons from other states with wolves suggest population management is not
robustly correlated with conflict minimization. Generally, the public has a high expectation that state
wildlife agencies will address wildlife related challenges.
Avoiding misinterpretation of maximum vs. minimum population metrics: It is important to use clear
and consistent messaging to reinforce the purpose of minimum population counts/estimates, which are
not intended as population objectives or maximums and have been misinterpreted in other contexts.
Zonal management: Initial and long-term management should be impact-based. Zonal management of
conflict could be a consideration for future management. Delineation of zones in the future could be
informed by experience and data gathered through impact (and conflict)-based management,
understanding of ecological and social suitability (inclusive of wildlife and agricultural interests), and
learnings from wolf dispersal and establishment on the ground.
Wolf population self-regulation: Intrinsic self-regulation of wolves is unlikely at a statewide scale;
wolves will likely be extrinsically regulated particularly by social carrying capacity. Wolf population selfregulation does not achieve the same goals as conflict management.
Positive impacts and wolf management: Positive and negative impacts can occur due to wolf presence;
positive impacts do not generally require hands-on management but can be communicated through
education and outreach and can inform management activities and funding opportunities.
Non-lethal livestock conflict minimization: Adoption of proactive and reactive non-lethal conflict risk
reduction techniques by livestock producers in Colorado is important to the long-term success of the
wolf restoration and management program. The effectiveness of these tools is context-specific and not
well quantified.
Post-depredation management of conflict wolves: While wolf depredations on livestock in other states
are uncommon and do not represent a notable burden to the livestock industry as a whole, some wolves
do cause significant problems for some ranchers and some areas experience repeated and frequent wolf
depredations on livestock. Management of wolf-livestock conflicts following depredations should allow
flexibility for managers; non-lethal and lethal management techniques should be applied adaptively and
are context-specific. To be effective at reducing further depredation events, lethal and non-lethal
responses for resolving conflict should be applied quickly and properly. Relocation of depredating
wolves has little technical merit.
Lethal management of conflict wolves: Lethal and non-lethal management are both critically important
tools for conflict minimization; lethal management will likely attract greater social attention. In
evaluating the management approach on a context-specific basis, consider the trade-offs among ability
to target depredating wolves, conflict minimization efficacy, cost, reproductive and recruitment success,
wolf population size and listing status, impacts to livestock producers, and social/stakeholder interests
when considering lethal take options, including incremental and whole pack removal.
Considerations for ecological effects: Ecological function is an important factor to consider but is
difficult to quantify and may be less relevant as a metric at the state scale.
Impacts of wolves to ungulates, big game, and big game hunting: Although statewide impacts to
ungulate populations and hunting opportunities have not occurred in other states and are unlikely in

Colorado, wolves can have local impacts to ungulate recruitment due to predation of young ungulates.
Wolves prefer elk and will also prey on deer and other ungulates; moose may be targets of predation
where they are abundant. Reduction in big game hunting opportunities and targeted wolf control have
sometimes occurred locally in other states to address negative ecological or economic effects of reduced
ungulate populations. Ungulate populations are impacted by a complexity of interacting factors.
Impacts of wolves to prey compromised by infectious disease: Predators like the gray wolf may select
for prey compromised by infectious diseases, which could prove useful in reducing infectious disease
prevalence in ungulate populations, primarily when pathogens are directly transmitted among hosts.
The strength of a potential disease reduction depends on numerous factors, including specific disease
etiology, the strength of selection for infectious individuals, and overall predation rates. It is unclear
whether wolves will have a measurable effect on chronic wasting disease (CWD) in Colorado, where
environmental contamination is likely to be a primary transmission route and where CWD is already
well-established in mule deer, a species that wolves generally do not select for in the presence of elk.
Interactions with other wildlife species: Wolves are important components of trophic networks where
they are present on the landscape and their presence may have interactions with other large carnivores.
The presence of wolves will not have an impact on populations of threatened and endangered species in
Colorado, specifically lynx and Gunnison sage grouse.
Management of conflict with humans: Attacks by wolves on humans are exceedingly rare; education
and outreach for recreationists and other public lands users should include best practices and guidance,
including how to differentiate wolves and coyotes. Flexibility to address rare instances of wolf
habituation in areas dominated by humans is important.
Management of conflict with pets and hunting dogs: Wolf attacks on pets are uncommon; education,
outreach, and management should be used to proactively prevent conflict. It is important that public
messaging emphasizes the risks assumed when domestic and hunting dogs are present in areas with
wolves.
Wolf monitoring and expectations for stakeholders and public: Monitoring and research should be
based on restoration and management goals, use a variety of techniques, and be connected to other
elements of wolf management, including conflict minimization. While robust monitoring is valuable at
early stages of reintroduction, limitations to monitoring will increase with wolf population growth,
requiring transition to a population estimate approach. It is important to consider effective messaging
and coordination with stakeholders and the general public when communicating monitoring objectives
and data; lead with trust and share data on an as-needed basis.
Social and/or economic dimensions of wolf management: Social and economic dimensions are critical
to understand, measure, and incorporate into decisions on wolf management. Perceptions of wolves
and perspectives on management vary among people, are generally consistent within interest groups,
and often reflect deeply held beliefs and values. There is high potential for social controversy and
conflict, particularly as related to expectations and acceptance for use of non-lethal practices, lethal
control, recreational harvest/regulated public hunting, and wolf population numbers. Some research
suggests that economic benefits can be substantial and much larger than economic costs; however,
economic benefits and costs are not distributed equally across stakeholders and the public. Consider the
breadth of existing social science research, economic indicators, and stakeholder and public feedback
when making management decisions, and incorporate new social and economic research into future
decisions. Education and outreach can also inform and be informed by social science. It is critical to have
trusted, responsive managers on the ground and consistency of management.

I.

Purpose and Scope of the Technical Working Group
The purpose of the Technical Working Group (TWG) is to review objective, science-based
information as well as provide its own knowledge and experience at the state/federal/tribal
level to inform the development of the Colorado Wolf Restoration and Management Plan. The
TWG is composed of members who bring experience in wolf reintroduction, wolf
management, conflict minimization, depredation compensation, and other relevant topics.
Colorado Parks and Wildlife (CPW) staff will synthesize information, relevant research, and
lessons from other locations and develop draft language and/or alternatives that will undergo
internal CPW review. This draft language and/or alternatives will then be shared with the
TWG for review and assessment of technical legitimacy for inclusion in the Plan. The TWG
may also provide input to CPW on language or alternatives with technical merit that could be
utilized to address feedback of the Stakeholder Advisory Group. In gathering feedback from
the TWG on draft language and/or alternatives, CPW may utilize subgroups comprised of
members of the TWG, and/or may consult with additional experts from outside of the TWG
for insight into specific topic areas where specific knowledge may be lacking in the current
TWG membership.

Introduction
This report summarizes Wolf Restoration &amp; Management Plan Technical Working Group1 feedback to
date regarding options for the following restoration logistics, with discussion of 1) technical merit of
each option, 2) technical preference among options, and 3) additional considerations:
1. Capture considerations: Donor populations; Capture methods at source; Age ratios; Color
ratios; Sex ratios; Genetic considerations; Animal reputation; What to do with injured animals at
source site; Transportation method from source to Colorado
2. Animal handling considerations: Feed options; Where and how to hold animals prior to
shipping and upon initial arrival in Colorado; Immobilization drugs to be used; Collars/marks on
animals initially reintroduced into the state; Samples collected from animals; Veterinarian care
in captivity; Disease testing and vaccine treatment
3. Reintroduction considerations: Reintroduction technique; Time of year; Considerations of
general landscape characteristics where wolves could be released; Pace of wolf reintroduction;
When to stop and/or pause reintroduction Number of release sites (and number of release
areas)

Capture considerations
Donor populations
Alternatives considered: Idaho; Montana; Wyoming; Mix of Northern Rockies States; Washington;
Oregon; Great Lakes; and Mexican Wolves
Capture and translocation of wolves from other states for translocation to Colorado will require
authorization by the respective state wildlife Commission or agency Director. A decision process in the
donor jurisdiction(s) will be required for such a project, which will need to be initiated well in advance of
project initiation.

About the TWG: The purpose of the Technical Working Group (TWG) is to review objective, science-based
information as well as provide its own knowledge and experience at the state/federal/tribal level to inform the
development of the Colorado Wolf Restoration and Management Plan. The TWG is composed of members who
bring experience in wolf reintroduction, wolf management, conflict minimization, depredation compensation, and
other relevant topics. CPW is responsible for writing the Wolf Restoration and Management Plan. The Parks and
Wildlife Commission (PWC) serves as the decision-making body responsible for approving the Wolf Restoration and
Management Plan. The TWG serves in an advisory capacity to Colorado Parks and Wildlife, offering non-binding
input into the development of plan content. The TWG is not a decision-making body and has no authority on wolf
management policy, research, or operations. The TWG operates by consensus. For purposes of the TWG,
consensus refers specifically to general agreement, or lack of objection, that an option or alternative has sufficient
technical merit to be recommended for consideration by CPW. In the absence of consensus, dissenting views will
be documented.

Technical Working Group (TWG)
to Colorado Parks and Wildlife (CPW)
November 2021
Final Report on Restoration Logistics
Summary of TWG feedback: All alternatives have technical merit. Comparatively, the preferred options
from a technical perspective, are:
● Idaho, Montana, Wyoming, and a Mix of these Northern Rocky Mountain (NRM) states are
recommended as the preferred donor populations, as logistical, source site jurisdiction, and
other considerations allow. Planning for all three states and keeping options open and flexible is
also recommended both for the initial donor population and for subsequent donor populations
as needed. Some TWG members recommend Wyoming as slightly preferred.
● Washington and Oregon are next in preference.
● Great Lakes are third in preference: wolves from this region should only be further considered if
other options above are not available.
● Use of gray wolves from the above states would be consistent with state law in Colorado, which
states that Canis lupus must be reintroduced to the state.
o State law does not specify the source of the wolves, nor does it describe the differences
among subspecies. With the exception of Mexican wolves, all other wolves in the
western US are managed as a single entity, and use of gray wolves from ID, MT, WY,
WA, OR, and the Great Lakes would be appropriate for reintroduction to Colorado as
well as consistent with state law.
o Wolves that have naturally colonized and were reintroduced to the NRM states are
different subspecies than were mapped to have previously existed there, though
delineating precise lines of where one subspecies’ distribution ended and the other’s
began is not possible. The animals reintroduced are of comparable size and weight as to
what was historically in the NRM and in Colorado.
● Mexican Wolves (C. l. baileyi) are lowest in preference; Mexican wolves should only be further
considered if other options above are not available as substantial process hurdles are presented
with the consideration of this uniquely listed entity under the Endangered Species Act. Colorado
is not historical range for this unique subspecies. The existing 10(j) for Mexican wolves could not
be expanded into Colorado, as habitat has not been demonstrated to be irreparably damaged
within the historical range of the subspecies. Utilizing Mexican wolves in Colorado would
essentially be placing a Federally Endangered Species in the state, with no recovery
goals/commitments for the state but with a long horizon as the species is eventually recovered
within Arizona, New Mexico, and Mexico. It would not be possible to extend the management
flexibility afforded by the 10(j) designation within the Mexican Wolf Experimental Population
Area which would lead to extremely challenging management scenarios.
● All decisions are subject to future conversations and decisions with potential donor states.
Rationale/discussion:
Wyoming
● Wyoming has an aerial capture system that is somewhat predictable to time. This could
facilitate the scheduling of successful capture and increase the likelihood of catching wolves and
thus a capture/shipment event could be planned to move wolves to CO.
● To meet statutory obligations and keep costs down, Wyoming may be a good state to begin
sourcing. However, it is important to keep options of where to source from open as there is no

guarantee wolves will be available or that they can be captured in the predator zone when
reintroduction begins.
At least one of the currently documented wolves in Colorado naturally migrated from Wyoming
and is currently successful, which may support sourcing from Wyoming. On the other hand,
sourcing from states other than Wyoming could provide genetic variability as a complement to
the natural migrators. However, it was alternatively suggested that the genetics in Wyoming are
similar to those in other NRM states and that genetic variability is not a concern should
Wyoming be chosen as a source of wolves.
Wyoming has a smaller population of wolves and a requirement to maintain a minimum number
of wolves, whereas, by comparison, Idaho and Montana have higher populations and may be
easier to source donor wolves from. Wyoming has fifteen to sixteen breeding pairs currently,
enough to theoretically provide five to ten wolves per year: this currently includes some animals
in the predator zone where wolves can be legally killed.
If WY is chosen as a donor population, wolves will be much closer to home so the homing
instinct may be greater and may raise the risk of return to the predator zone where they could
be harvested, leading to public criticism.
It is also recommended to keep options open for getting wolves elsewhere, if available, at later
dates. Although genetics are a non-issue now, some new genetics would have benefit if wolves
reintroduced from places other than WY are used and become breeders.

Idaho, Montana, Mix of Northern Rocky Mountain Region states (MT, ID, WY)
● Considerations in support of sourcing donor populations from Idaho, Montana, and Wyoming
include: the high number of wolves in those states (MT and ID); the very recent legislation in
place around the status and management goals for reducing numbers of wolves in those states
(MT and ID); generally negative public attitudes toward wolf presence in those states; that
taking wolves from states where hunting is allowed may provide wolves that come with a fear of
humans (MT, ID, and WY); that the prey preference of wolves in those states is elk (MT, ID, and
WY); and their genetic viability (MT, ID and WY).
● Matching to the extent possible the ecological conditions at the capture and release sites
(primary prey, migratory/resident behavior of prey, likely denning habitat, etc.) is important. In
that sense, wolves across much of WY, MT, ID, eastern OR, and eastern WA would very likely
work for western Colorado, where the primary prey is likely to be migratory elk that generally
move from intermountain valley or lower elevation winter ranges to high elevation summer
ranges.
● A recent genetic analysis of wolves in the Northern Rockies found a genetically connected
population, such that selection of source wolves on a genetic basis was not a significant issue.
Genetic variation is unlikely to lead to different behaviors.
● Maintaining contingency plans for other potential donor populations is important in the case of
lack of availability or other obstacles.
● Proximity to Colorado’s border, which facilitates some transportation logistics, was also
considered as a factor of donor selection.
● It was also suggested that positive public perceptions of Yellowstone wolf populations may
make them/NRM wolves more favorable for use as a source population. However, the public
interest in individual wolves specifically from Yellowstone National Park; tolerance of those

Final Report on Restoration Logistics
wolves to humans; and policy processes make selection of donor populations from Yellowstone
NP less desirable. Social acceptance may be low for removing and/or managing Yellowstone
wolves outside of the park and thus sourcing wolves from the park is cautioned against.
Washington and Oregon
● Selection of donor populations from Washington and Oregon would be less favorable than
selecting wolves from other NRM states, but the option still has technical merit. Although
Washington and Oregon wolves are also NRM wolves, Idaho, Montana, and Wyoming donor
populations may be in greater alignment with public preference, for political reasons, as
compared to the Pacific Northwest donor populations.
● Both Washington and Oregon have programs to capture wolves in winter; however, winter
conditions in November and December affect potential success; increased cost and longer
transport times also make these states less preferable than other states discussed above.
Great Lakes
● Selection of donor populations from the Great Lakes region has technical merit but is of lesser
preference as compared to the Northern Rockies and Pacific Northwest.
● Great Lakes wolf populations are a viable candidate with respect to taxonomy (as are all source
locations under consideration as previously described); however, the dissimilarity of the
ecological context between the Great Lakes states and Colorado makes this a less favorable
option as a donor population. Although there is some historical and contemporary measure of
genetic mixture between coyotes and Great Lakes wolf populations, this is not considered an
exclusionary factor for Great Lakes as a donor population. Although use of Great Lakes wolves in
the restoration effort in Colorado could have technical merit, wolves from this region should
only be further considered if other options above are not available.
Mexican Wolves (Arizona/New Mexico)
● Mexican wolves (a subspecies of gray wolves, listed as a separate entity under the Endangered
Species Act) is the least desirable of the considered options. The historical range of the Mexican
wolf does not include Colorado. Because they are listed as a unique entity under the ESA,
maintaining the genetic uniqueness of this subspecies is paramount. If Mexican wolves were
present in Colorado, premature interbreeding with wolves from the north could compromise
the Mexican wolf recovery effort. Management considerations to address this potential issue in
the Mexican wolf geography of recovery (AZ, NM) will reside primarily with the USFWS Mexican
Wolf recovery team. Should gray wolves from other source populations described above be
used as donor populations to Colorado, coordination between the Mexican Wolf Recovery
Program and CPW is recommended to plan for and address potential interbreeding.
● Although the TWG discussed that use of Mexican Wolves in the restoration effort in Colorado
could have technical merit, it recommends that Mexican wolves could only be further
considered if all other options above are not available.

Final Report on Restoration Logistics
Breeding programs
● A member of the TWG discussed whether CPW should consider use of a repository of unique
genes from a captive population of the McCleery lineage of Great Plains ‘buffalo wolves’ (C. l.
nubilus) as part of the gray wolf restoration effort.
● It was suggested by this TWG member that inclusion of this breeding program as part of the
restoration effort could potentially conserve and restore unique genes from the original wolf
population inhabiting the general region, enhance the populations’ gene pool, maximize genetic
diversity, and restore genes that would not necessarily be available in any other donor
populations of wolves that could be used for restoration in Colorado.
● Several other TWG members raised technical concerns about high levels of inbreeding of the
McCleery lineage as well as limited amount of genetic material available for artificial
insemination and the overall conservation benefit; therefore, it is very difficult to assume that
introduction of these genes is a net positive to the effort.
● Use of these genes is not recommended in the early years of restoration if they are to be used at
all. If using a cross-foster method where pups of this lineage are bred in captivity and then
introduced to established wolf dens, or artificial insemination of wild wolves, this would occur in
later years of the restoration effort.
● One TWG member suggested that adding this genetic material does not address a need or an
issue of low genetic diversity, as there is no evidence for low genetic diversity for the source
populations of wolves being considered. While not the case, if the source populations were
documented to have low genetic diversity, then there might be a reason to seek other genes to
solve this currently non-existent problem.

Capture methods at source
Alternatives considered: Net gunning; helicopter darting; traps; snares; discretion of source population
management; public trappers; other options.
Summary of TWG feedback: All alternatives have technical merit. The most preferred options are use of
a net gun, helicopter darting, and discretion of source population managers, in no particular order.
Snares and traps present a variety of concerns related to success rates and injuries.
Rationale/discussion:
Net gunning and helicopter darting
● Biological and social considerations support preference for helicopter darting and net gunning
as capture methods. These techniques offer the most precise, data-informed predictive planning
options and temporal relevance for fall and winter reintroduction efforts in the Northern
Rockies. Either darts or net guns could be used depending on the landscape; helicopter work will
be more challenging in highly forested landscapes and thus darting may be the only option if a
helicopter is used. A well-coordinated helicopter pilot and gunner is important when
undertaking a helicopter darting or net gunning capture method.

Darting and helicopter capture also provide the best selective potential; however, even these
methods are non-selective, particularly in forested areas. The agency may need to consider
capturing more wolves than needed to be somewhat selective in taking the desired age, color,
and sex ratios in addition to the most fit animals (see below). Use of immobilizing drugs also
accompanies these options.
The use of an advanced spotter plane is recommended to locate wolves, to determine if they
are in a workable location, and - if in a workable location- to determine what direction is best to
approach them from and to keep an eye on the pack as they scatter once captures are initiated
with a helicopter. When wolves selected for transport are shuttled to a holding location, the
spotter plane can be used to locate other wolves for the helicopter to pursue once the shuttle is
complete.
Weather conditions may also constrain capture efforts. For example, snow conditions in the
Pacific Northwest create difficulty for helicopter capture until closer to February, although a
December capture event could be possible. It is valuable to have local staff as scouts to gauge
snow and weather conditions in local environments; the ability to predict snow conditions can
also improve the speed and efficiency of capture.
A capture team with ample experience and a history of successful wolf captures will be required
for helicopter captures to be a viable option. Helicopter wolf captures are generally more
difficult and time consuming than helicopter captures for big game, and experienced pilots and
capture crews can be successful where less-experienced teams cannot.
Wolf capture is generally not a profitable enterprise for helicopter charting companies, and
there is likely to be competition with their ungulate capturing enterprises. This may lend to
having an alternative method to capture wolves; overreliance on helicopters alone could slow
down the process.
“Judas Wolves” are wolves that are captured and released back into the source population with
collars such that they can offer options to track and capture wolves for relocation in future
years’ efforts.
Even with assistance from methods such as “Judas Wolves” or experienced tracking teams, plan
for multiple options with low, feasible goals of the number of wolves captured per trip. For
example, planning three to four events to capture two to three wolves per trip could be a
feasible pace of capture, which would support a medium pace of release. However, lack of
familiarity with landscape and pack dynamics is a limiting factor in the pace of reintroduction.

Traps and snares
● Traps and snares have technical merit; however, multiple TWG members advocated against the
use of snares and traps as a capture method. Seasonal considerations can complicate capture
and release coordination times; foothold traps have limitations based on weather. Neck snares
can lead to significant and often unseen injuries to wolves. In past reintroductions, some wolves
badly injured by neck snares were rejected as potential donors while others needed veterinary
treatment after being damaged by traps. If selected, use snares with stops to prevent
strangulation.
● Negative public perception can accompany release of potentially damaged wolves; there may be
a heightened fear that damaged wolves could not hunt naturally and would prey on livestock.
While the use of trapping generally polls negatively with the public, it polls less negatively when

the purpose of conducting trapping is to enhance wildlife populations rather than be employed
as for the purpose of regulated take.
If traps and snares are to be used, consider strict regulations around the type of device,
including features such as coil strength, and the need to check traps within every 24 hours to
prevent freezing if wolves are caught in the winter. Trapping can be very effective if experienced
trappers are employed (e.g., agency or professional public).
Captures involving trapping are most likely to occur the summer/fall prior to reintroduction to
fit wolves in potential donor packs with collars to aid in leading capture crews to their pack
mates come winter. (See Judas wolves, above)
Although novel capture techniques and technologies may be useful, there are capture
techniques that have been proven effective in the NRM over the past twenty-six or more years:
there is not a need to change approaches at this time.

Public trappers
● Public trappers can work in tandem with net gunning and helicopter darting tools. Use of public
trappers can provide potential additional economic benefit that may viewed favorably by donor
states; one TWG member recommended avoiding using government trappers to avoid
perceptions of bias and to ensure leading edge approaches. This option requires cooperation
between state agencies in the source area and public trappers. In Montana, for example, if
Colorado can contract with trappers directly, so they could earn money for their effort (as they
may have otherwise, such as if they sold the pelt from a harvested wolf), the request to a state’s
wildlife commission could be to allow the trappers to capture live wolves to support this effort.
Public trappers could also be used to assist agency personnel in capturing and collaring wolves
the summer prior to captures in areas that are likely to be accessible to winter capture
operations (See Judas wolves, above). While some wolves may not survive to winter, those that
do will enhance the ease of winter capture.
Discretion of source population management
● Consider source population management and policies in potential donor population states.
Some TWG members expected Montana policies to be highly favorable to selection for donor
sourcing; others noted policies around species management in Montana, Idaho, and Wyoming
may constrain sourcing options. Immediate engagement with potential donor states’ game and
fish agencies is important to build relationships in anticipation of potential donor selection, with
considerations of the current political landscape in these states.
Additional logistical considerations for capture
● Coordination, knowledge, and understanding of populations, policies, and local officials in the
source states enhance efficiency of capture; outreach to potential states’ officials should be
conducted as soon as possible.
● Advance work and coordination would greatly help in achieving a successful reintroduction by
the end of 2023. Coordination with local officials from donor states may allow for early collaring
of “Judas Wolves”, which could add efficiency in capture: this could be done as early as 2022.
Montana has six experts which coordinate to collar about twenty wolves per year over the

course of two to three months of summer trapping and a month of helicopter capture efforts in
the winter. Similar capture and collaring efforts occur annually in Idaho and Wyoming.
The National Park Service in the Northern Rockies states also have considerable infrastructure in
place to assist capture, although, as mentioned above, there are also cautions against selecting
wolves from Yellowstone National Park, given their notable public reputation.
Capture methods selection is related to location of the source population and access to animals
and holding and transport (including potential need for pens near the capture site) are also
considerations.

Age ratios
Alternatives considered: Young of the year; yearlings (one year old); dispersing age (two years and
older); mature animals; and a mix of young and mature animals.
Summary of TWG feedback: All alternatives except for young of the year have technical merit, with no
preference among the remaining alternatives.

● There may be some value of mature over younger individuals, as long as a wolf is not senescent.
● Young and mature wolves have little difference in dispersal patterns or predation behaviors:
these features are more dependent on the individual wolf than on the age of the wolf.
● Having sexually mature wolves would be sufficient; and selection for age in capture methods
may be limited.
● Yearlings and breeding age animals are most likely to be the most encountered animals in
capture events. These animals are likely to be successful in Colorado.

Color ratios
Alternatives considered: Gray; black; mix; does not matter.
Summary of TWG feedback: All alternatives have technical merit. Selection by color generally does not
matter and in general the color mix is dependent on what wolves are captured (‘you get what you get’);
use of a mix of colors was preferred slightly over a single color.
Rationale/discussion:
● A heterozygous black wolf has been found to be slightly resistant to disease, as opposed to
homozygous black or grey. This difference is very minor, but given that research, having more
heterozygous black wolves could lend a survival advantage: yet this would not be possible to
determine during capture.
● Black wolves also look more dissimilar to coyotes, are more visible, and thus may reduce illegal
take resulting from wolves being mistaken for coyotes; on the other hand, if more easily
identified, this could more easily facilitate illegal poaching.
● Gray wolves can have black pups and vice versa; some research in Yellowstone suggests gray
and black wolves seek each other out when forming new packs more than wolves of the same
color as it may provide some evolutionary benefit.

Sex ratios
Alternatives considered: Female skewed; male skewed; or 50:50.
Summary of TWG feedback: All alternatives have technical merit; the preferred option is a 50:50 sex
ratio mix; followed by preference for a female skewed initial population; and least preference for a male
skewed initial population.
Rationale/discussion:
● A goal of a 50:50 mix can help to avoid unnecessary releasing when capturing donors, based on
the probability of male/female capture.
● Female skewed sex ratios may improve denning success.
● Helicopter darting and net gunning may slightly enhance the ability for selectivity. However, this
will be dependent on where donor wolves come from (more open vs. heavily timbered
locations).
● Males disperse more whereas females have higher reproductive success and have higher
success of joining existing packs; however, the latter is not relevant when there are no
preexisting packs.
● Because wolves are monogamous, skewing the sex ratio is not likely to help with reproduction.
In Oregon, multiple instances have been documented in which a new male comes into the pack
and breeds with a breeding female and her 2-yr-old daughters. In this case, skewing the female
ratio could increase reproduction: however, it is unclear that this would happen in a
reintroduction scenario when there are not preexisting packs.
● In some cases, whatever wolf presents an opportunity should be captured regardless of what
sex and age it might be because that may be the only opportunity for a capture. In many cases,
the specifics are determined when wolves are in hand.

Genetic considerations
Alternatives considered: Related pack members; unrelated, dispersing age animals; mix of packs and
unrelated individuals.
Summary of TWG feedback: All alternatives have technical merit, with highest preference for unrelated,
dispersing age animals; followed by preference for a mix of packs and unrelated individuals; and least
preference for selecting only related pack members.
Rationale/discussion:
● Sourcing and capture of whole packs would be more laborious, costly, and constrain sourcing.
Under the conditions of a hard release, the pack is more likely to split than stay together,
providing support to not intentionally pursue an entire pack.
● As more members of a pack are removed, the pack can become destabilized at the source
location, potentially leading to unintended consequences at the source. It was noted that a
similar outcome was observed when members of the depredating pack were relocated to

minimize conflict. However, destabilization vs. resilience of the pack at the source site may be
specific to the age class removed. The removal of breeding females is most likely to destabilize
the source pack, followed by breeding males; juveniles through two year-olds that are removed
from the pack appear to have less repercussions on the stability of the source pack.
If a hard release is used, there is limited impact/benefit of selecting related vs. unrelated
animals on the dispersal patterns of released animals.
There are some concerns that reproductive potential will be low for genetically related animals
in localized release locations. However, a recent study in the Northern Rockies and Pacific
Northwest that is near conclusion found that while there is some genetic structuring around the
edge of the distribution (as expected of any species’ population), there is a lot of genetic
diversity and mixing across the whole region. Wolves have evolved mechanisms to minimize the
effects of inbreeding, so inbreeding is likely to be a non-issue even if related wolves are released
close to one another in space and time.

Animal reputation
Alternatives considered: Not known to be a depredator; known depredator; wolves that have been
around livestock without conflict; wolves that have not been present around livestock at all
Summary of TWG feedback: The alternatives “not known to be a depredator,” “wolves that have been
around livestock without conflict,” and “wolves that have not been present around livestock at all” were
all determined to have technical merit as factors for sourcing donors; “known depredator” has technical
merit as a criterion for exclusion from sourcing. Sourcing donor populations not known to be
depredators (whether present around livestock or not) was preferential to sourcing populations not
exposed to livestock, if possible. However, it is important to consider that most wolves overlap areas
with livestock, and there is not a way to know the degree of interaction they have had with humans. No
wolf should be translocated that has a known history of chronic depredation, and sourcing from
geographic areas with chronic depredation events should not occur.
Rationale/discussion:
● There is nuance in determining depredation habits, with consideration of trends in the behavior
of an individual and a pack. If a wolf is depredating livestock, the pack it belongs to is likely to
depredate as well; additionally, if a pack is depredating, it is difficult to exclude one individual as
non-depredating (see the Beartrap Pack’s records of bison depredation). A known wolf or pack
of wolves that have been identified as chronic depredators by the source location should not be
used for translocation to Colorado.
● If a pack has had infrequent depredation events, as opposed to a chronic and well-known
tendency to depredate, this should not, from a technical perspective, necessarily exclude
consideration of a wolf or pack as a potential donor. However, from a social perspective, striving
to use wolves with no known history of depredation is recommended. The history of a wolf’s
exposure to livestock populations is a consideration for potential for depredation. Sourcing from
a pack that has not been exposed to livestock or a significant livestock grazing presence could be
preferable: such packs exist in the central or northern Idaho wilderness, areas which have low
grazing presence and scarce livestock, respectively. However, it might be more limiting than

●

beneficial to constrain potential source populations to areas that are not suitable for livestock.
Sourcing from populations which have been exposed to livestock, such as many populations in
Montana and Idaho, but do not have a history of depredation, could also be preferable.
Because depredation is situational, even wolves that are not known to be depredators have the
potential for depredation. Situational factors could include public lands grazing and the
vulnerability of livestock. Overall, it is difficult to predict depredation behavior.
A study of wolf-livestock depredation in Montana found that depredation tends to recur in the
same places, and the majority of livestock depredations are concentrated in those places. Places
with recurrent livestock depredations tend to be places with higher livestock density, higher
wolf density, and with intermediate proportions of public land (e.g., about half public land
juxtaposed right next to private land that is about half of the area as well). There is at least a
possibility that depredations are characteristics of the landscape rather than the wolves that are
there (i.e., any wolf that lives there may eventually become involved in livestock depredations).
While these areas can be avoided as sources for donor populations, depredation as a function of
landscape characteristics suggests that it may be less likely to identify wolf packs that are more
or less likely to depredate. Areas known to have chronic depredation should be avoided as a
source of donor populations.

Disease issues at source sites
Alternatives considered: Prioritize areas for wolf capture as being those without disease.
Summary of TWG feedback: The alternative “sourcing from areas without disease issues” was
determined not to have technical merit.
Rationale/discussion:
● Sourcing populations from areas without disease issues is not technically feasible. All wolves
have some pathogens and parasites, such as endo- and ectoparasites, Echinococcus, or canine
distemper/parvovirus: this is consistent throughout all populations. A determination of which
diseases are parameters for exclusion should consider the diseases that already exist in
Colorado; for example, any disease coming out of Montana is likely to already be present in
Colorado. Overly broad criteria for exclusion due to pathogens or parasites will significantly limit
potential source populations. Be deliberate in selecting populations without known issues and
manage public reactions to sourcing diseased wolves via treatment during transport and
through education on disease in the wild.

What to do with injured animals at source site
Alternatives considered: Release at source site; treat and release at source site; treat and release in
Colorado; consider euthanasia.

Final Report on Restoration Logistics
Summary of TWG feedback: All alternatives have technical merit. Utilize capture methods to minimize
injury and avoid major injuries altogether. No alternative was most preferred; however, “treat and
release at source site” was least preferred.
Rationale/discussion:
● In general, it is critical to select the most appropriate capture method, have standard protocols
around capture and treatment (e.g., reference manuals from Yellowstone), and follow
veterinary advice for appropriate treatment. This will also help assuage public concern or fear
regarding injured wolves.
● The alternative selected depends on the severity of the injury. Injury will likely occur during
capture; capture method largely determines frequency and severity of injuries (see above).
Treatment for the minor injuries incurred during darting and net gunning is feasible and easy.
Also consider the importance of maintaining capture and treatment methods that would not
competitively disadvantage source individuals, and potentially make source populations more
likely to prey on livestock.
● Minor injuries are injuries that could be addressed in a single treatment and do not require
extended care. Provided there are no significant concerns, plan to translocate animals with
minor injuries. Consider a more extensive rubric of conditions that might prevent translocation
(e.g., multiple missing digits, multiple missing canine teeth, advanced age/unhealthy, etc.).
● Major injuries should be assessed and treated under veterinary guidance; do not translocate
animals with major injuries. Major injuries would be those that would require repeated
treatment, extended holding, or cannot be treated and require euthanasia. Portable
radiography may be beneficial to have available in making assessments of injuries.
● Alternatives to treatment, such as euthanasia, for injured wolves at the source site not deemed
viable to be used as a donor individual should consider veterinary input and local ordinances
and protocols from source states. Euthanizing drugs lead to bioaccumulation and should not be
used unless the carcass is retrieved. In cases of euthanasia, remove heads to prevent skull
collection.
● Long-term care options should also be considered.
● If an animal is not healthy enough to be released into Colorado, it is up to the source site
managers to decide whether it is healthy enough to be released back into the source
population. Make sure that wildlife veterinarians from the donor jurisdiction and CPW are
involved in capture plans and part of the capture team, so they can make real-time decisions
about injury treatment and euthanasia. Defer to CPW and source site veterinarians as
appropriate.

Transportation method from source to Colorado
Alternatives considered: Air; ground; mix.
Summary of TWG feedback: All alternatives have technical merit, with no group preference among the
alternatives; each has situational relevance according to the plan of capture and translocation. Key to
success is that capture, transport, and release should occur as quickly as possible to minimize time in
captivity and stress on the animals.

Final Report on Restoration Logistics
Rationale/discussion:
● There is a trade-off between the cost and time of each alternative and options are situationally
dependent on the location (e.g., need for over-snow vehicles).
● Volunteer aircraft may help to reduce costs.
● Keeping options open enhances the latitude and flexibility of decision making in the
translocation process, especially in the case of inclement weather and unexpected conditions.
● For air transport, consider holding pens near the capture location, transport to the airport in
trucks via large crates, use of a cargo-type aircraft that can hold multiple crates for quick
transport to Colorado, and transport from airport to release location via vehicle, helicopter or
any other transport method.
● Consider the most appropriate handling crates for holding and transport, including
consideration that crates provide protection such that wolves cannot chew them. TWG
members can provide further details, experiences, and design recommendations from past
reintroductions.

Animal handling considerations
What to feed during a period of captivity
Alternatives considered: Roadkill; carnivore logs; minimizing captivity time and feeding needs;
ice/snow/free water.
Summary of TWG feedback: All alternatives have technical merits, with various practicalities to
consider. Regarding food source, minimizing captivity time and feeding needs is preferable, followed by
carnivore logs (typically, conditioned horsemeat) and roadkill. Ice/snow/free water are all
recommended.
Rationale/discussion:
● Slight preference for carnivore logs over roadkill is due to the additional logistic details to
consider with sourcing roadkill, such as availability, concerns that roadkill could have been
poisoned, and prions and other diseases that exist in roadkill, all of which would need to be
coordinated with the Colorado (and source state) wildlife health program. Carnivore logs would
help guarantee the standards of having available food at a rate of ten pounds per animal per day
of captivity.
● Stress in a condition of captivity prevents some wolves from feeding. Feeding approach depends
on release method: The goal of a hard-release translocation should be to reduce the amount of
time in captivity, and thus reduce the feeding needs. There are no data to suggest that a wellfed, hard released reintroduced animal would have more of a proclivity to stay close to their
release site than a hard released animal that was held in captivity for a minimal time and not
fed. Roadkill elk and deer would be preferred in holding pens at release sites if soft release is the
preferred method, but if capture and transport occurs rather quickly, food is not likely to be
needed.

Technical feedback on topics regarding social perceptions:
o Providing food may be important for some stakeholders from a public perception
standpoint. While feeding may not be biologically important during capture and
transport, this may depend on the length of holding and transport. It is still
recommended to make food available should it be needed, should delays or other
contingencies arise.
o There could be a social concern that use of carnivore logs would lead to a public
perception of training reintroduced wolves to eat cattle. The technical reality is that
carnivore logs will not create depredation tendencies. Wolves do not learn to prey on
livestock by eating dead livestock; feeding of carnivore logs does not precondition for or
against livestock predation.

Where and how to hold animals prior to shipping and upon initial arrival in Colorado
Alternatives considered: Bare bones holding facility to be used for as short a time as possible.
Summary of TWG feedback: Bare bones facility for as short a time as possible is preferred.
Rationale/discussion:
● This topic refers specifically to where and how animals are held, as needed, in their state of
capture as well as upon immediate arrival in Colorado. This topic does not refer to whether
wolves are hard released or moved to a soft release site after initial arrival (see ‘Reintroduction
Technique,’ below).
● Minimize the period of captivity in a hard-release condition. Past experiences included public
scrutiny of the period of captivity; however, gray wolves are resilient and durable.
● Flexibility is key when approaching this issue.
● As noted in capture considerations, holding pens near capture may be needed, in part because
not all animals may be captured on the same day.
● Preparations and contingency plans should also be made for holding pens, as needed due to
weather or other reasons, in Colorado.

Immobilization drugs to be used
Alternatives considered: Telazol, tranquilizer use during transport
TWG feedback: Telazol is preferred as an immobilization drug for capture; tranquilizer use during
transport has technical merit but is not preferred and should be avoided. Travel and holding time should
be minimized and use of tranquilizers and immobilization drugs during transport should be minimized as
much as possible.
Rationale/discussion:
● Telazol is a standard immobilization drug used in previous processes and is the safest given its
streamlined application.

Tranquilizers for muscle relaxation (not sedation) should be avoided: if needed they should be
used under the direction of a veterinarian. Use of multiple drug regimens have previously
resulted in seizures and post-release mortalities, and there was advocacy to simplify the drugs
used.
Wolves can be successfully held in a shipping container without tranquilizers from twenty-four
to thirty-six hours from capture to release; simplicity is key.
Defer to CPW and other veterinarians as appropriate. Maintain flexibility to tailor drug protocols
to the specific situation.
As discussed above, consider the most appropriate handling crates for holding and transport,
including consideration that crates provide protection such that wolves that are not tranquilized
or immobilized cannot chew their crates.

Collars/marks on animals initially reintroduced into the state
Alternatives considered: VHF; GPS; mix of VHF/GPS; no collar; PIT tags; ear tags (perhaps temporarily
when in captivity)
Summary of TWG feedback: All alternatives have technical merit, except the alternative “no collar” for
animals initially reintroduced into the state. It is preferred that every released wolf has a GPS collar, with
variability in durability of GPS collar types as an important consideration. Ear tags are less preferred as
compared to the other collaring/marking alternatives.
Rationale/discussion:
● There is value in collaring every wolf reintroduced for monitoring and data collection purposes
and to learn from and improve upon for future releases; however, it is important to educate the
public and set expectations that not every wolf in Colorado will be collared as the population
grows. It is also important to understand that collars tell us where wolves have been but not
where they are present. Collaring can also help to catch poachers.
● For any collar used, ensure that the frequency used accounts for the potential for interference
due to environment/terrain or other collared wildlife and/or domestic dogs that share the same
frequency. Coordination with other states on frequencies will also help for tracking dispersers
into other states. Use of similar frequencies as neighboring states for wolf collaring is
recommended.
● Satellite-linked GPS collars can provide the best remote data but are more breakable/less
durable than VHF collars. There are tradeoffs in which GPS collars are selected based on
durability vs. frequency of monitoring; survey collars are more durable, but research-type collars
will provide more data points. Experiences in other states suggest that some brands may be
more reliable, albeit more expensive.
● VHF radio telemetry is more durable. However, any radio collar can have problems at any point
in time, and VHF frequencies -- as with other collars -- can be problematic, especially for
dispersers; given how much wolves move and how hard the signals can be to find (especially in
mountainous environments), some VHF collared wolves may be lost.
● VHF also forces biologists to be in the field and helps increase understanding of how wolves
interact with the landscape. This is seen as beneficial. When comparing the two, there is value in
the authenticity of monitoring and reporting to the public through use of VHF and the auxiliary

data collected while in the field, in comparison to the remote data collection via GPS collar.
However, costs of in field monitoring using VHF may not justify the cost compared to GPS. Be
certain that proper FCC licensing has been completed.
Consider use of GPS to start followed by later use of VHF as wolves begin to form packs; a
combination of VHF and GPS could also be considered upon release: however, this is less
preferred. When sourcing radios, use stout collars to mitigate damage from chewing.
Colored collars could discourage illegal harvest by distinguishing wolves from coyotes: however,
it could alternatively enable illegal harvest by making wolves more recognizable. Colored collars
can be helpful in the event of a report or a photo of a wolf with a failed collar.
Pit tags are preferred over ear tags due to robustness of monitoring and ear infections.
However, DNA studies on captive wolves may obviate use of pit tags, and it may be somewhat
expensive to pit tag every wolf. This should not be a requirement but can be employed when
feasible. There are no perfect marking identifiers, with tradeoffs to each; selection of tool will be
dependent on the goals and objectives of the monitoring program.
There is no justification for not placing a collar on an animal that is handled for the
reintroduction. All animals released should have a collar. Too much money and resources will
have been invested in each translocated animal and monitoring the success of reintroduced
animals is fundamental to the program.
Recommendations regarding use of collars for monitoring after initial release will be discussed
separately by the TWG in the future.

Samples collected from animals
Alternatives considered: Blood (red and purple tops); tissue; hair; photographs; fecal, other
Summary of TWG feedback: All alternatives have technical merit.
Rationale/discussion:
● Hair is not the best available sampling technique for genetics, especially for long term storage.
Consider a simple cheek swab, whether ear tags are used; an ear punch can be collected as well
(using a baby cryovial with desiccant).
● Weight, size, and basic physiological characteristics should be collected: these statistics help to
address public questions and misconceptions on reintroduced wolves.
● Preexisting anomalies on wolves should be documented to record that the capture team did not
negatively impact the wolf.
● Ectoparasites (if present) should also be collected.
● Whisker samples could be taken for stable isotope diet analysis.
● Consider collecting a minimum of 2 sample types from each animal in hand (2 genetic samples, 2
red top blood tubes, 2 EDTA blood tubes, multiple fecal samples, etc.) More would enable
banking them in different locations.

Veterinarian care in captivity
Alternatives considered: Defer to handling protocols
Summary of TWG feedback: As also discussed above, it is important to have standard protocols and for
experienced veterinarians to be involved when wolves are in captivity to assist with: animal health
monitoring, emergency care if necessary, sample collection, administration of vaccinations, etc.
Biologists that have experience handling wolves and/or other wildlife will also be on hand to fit wolves
with collar, ear tags, and/or PIT tags, and conduct basic monitoring, etc.

Disease testing and vaccine treatment
Alternatives considered: Test and treat everything possible
Summary of TWG feedback: Donor populations will have diseases and naturally migrating wolves will
bring them. For captured wolves, the general recommendation is to test and treat everything possible,
as this will help establish healthy populations; this will also help to foster social acceptance of
reintroduction protocols.
Rationale/discussion:
● See above discussion of disease.
● Echinococcus granulosus (tapeworm) has been of concern at times for stakeholders in Montana.
● Some treatments may require multiple treatments for efficacy.
● Defer to veterinary expertise when devising disease treatment plans.

Reintroduction considerations
Reintroduction technique
Alternatives considered: Hard release, soft release, combination
Summary of TWG feedback: All alternatives have technical merit, with hard release preferred to soft
release and to a combination of soft and hard release. There are pros and cons to consider for both
techniques; however, hard release has greater technical merit as well as greater logistical and economic
feasibility and is thus recommended by the TWG as the preferred technique.
Rationale/discussion:
● The key distinction between soft and hard release is related to acclimation. A hard release
would entail capturing wolves and immediately translocating and releasing them to a site in
Colorado, whereas a soft release would entail a period of conditioning wolves to their
surroundings in Colorado before they were released into the wild.

In experiences with soft releases in Yellowstone National Park (YNP) and hard releases in central
Idaho, both techniques worked. However, the hard release in Idaho was more successful in
terms of both survival and population growth. Thus, the perspective of technical outcomes, hard
release is preferred, and the logistical feasibility and associated economic burden of a soft
release should deprioritize consideration of this technique for Colorado.
Hard releases are quicker and cheaper, but their use may also length the time for individual
wolves to locate one another and pair up to produce offspring. Wolves may be more likely to
travel further from the release location.
In a hard release, there is some experience in transporting anesthetized wolves to a temporary
pen; however, biologists did not observe much difference in the outcome than in a normal hard
release.
A soft release may be more likely to limit dispersal, with packs more likely to stay together and
may be less likely to disperse and interact with livestock, decreasing conflict potential in the
short term. However, while documented in the NRM releases, these benefits should not be
overstated because wolves that are soft-released will still have post-release movement, as
exhibited within the first five years following the soft release in Yellowstone. There is also
variability of movement among individual wolves.
A soft release could be considered should specific areas be identified that are highly suitable for
wolves where there is a desire to keep wolves localized closer to the release areas. A soft
release strategy should also consider suitable habitat for where wolves will overwinter; pens
may need to be located at or near overwinter habitat. Soft release could be considered
particularly if there is concern that a lack of distribution of suitable habitat would limit the
success of and/or increase conflict with wolves that disperse following a hard release. However,
social-ecological suitability mapping data does not provide clarity that there is such a preferred
soft release acclimation site for Colorado.
o TWG members further noted that, while not a technical issue, using soft release to
attempt to address social concerns about post-release movement could create other
social concerns if specific communities are perceived as being targeted for having
wolves in their areas.
A mating pair may remain together in a soft release strategy to raise a litter after being released,
even if auxiliary members split. The soft release strategy with a related pack may build social
structure, foster greater reproductive potential, and attenuate dispersal, but at a significantly
greater financial and logistic cost. In the Yellowstone soft release, penned animals were
unrelated and matched via sex and age. Wolves are likely to disperse regardless of pack
dynamics; individual reputation would be a greater factor in conflict.
The soft release in YNP included significant resources, including building structures, patrolling
and staffing pens 24/7 while wolves were in the pens (for 10 weeks), and feeding wolves.
Existing infrastructure at Yellowstone enabled the construction and tending of pens, which was
not the case during the reintroduction effort in central Idaho.
There are questions regarding the feasibility of a soft release in Colorado, including whether
Colorado has the resources and manpower at its disposal to execute a soft release. The release
technique may largely be determined by logistics considerations (including whether there are
suitable sites for soft release) and funding.

Soft release in YNP also resulted in behaviors by wolves reflective of frustration with captivity.
Quick capture, moving, and release is preferred.
There is not a correlation between the method of capture and the method of release. Also,
experience in trapping wolves to relocate them away from livestock indicates that capture
practice had little to no effect on their dispersal patterns.

Time of year
Alternatives considered: Winter; spring; summer; fall
Summary of TWG feedback: Of the alternatives considered, spring and summer do not have technical
merit; winter and fall both have technical merit; and winter is preferred over fall.
Rationale/discussion:
● Summer and spring do not have merit because of the undue heat stress the seasons place on
reintroduced individuals.
● Fall presents risks of hunting season in the context of the vulnerabilities of recently reintroduced
wolves.
● Winter (November through March) is preferred due to colder temperatures; snow cover to
enable tracking; proximity to the first breeding season; proximity to annual peak ungulate prey
vulnerability; and greater ease of protecting livestock during winter.

Considerations for where wolves could be released
Alternatives considered: Land ownership; livestock presence; geographic context; prey base; likelihood
of supporting multiple packs; proximity to state border; vote results; seasonal elk supply.
Summary of TWG feedback: All alternatives have technical merit; vote results have least preference as a
technical alternative to guide reintroduction location, but it is recognized that socio-political
considerations will also be at play in selection of release area(s).
Rationale/discussion:
● A release area is any contiguous space where it is suitable for wolves to be released, whether via
a single discrete release site or at multiple discrete release sites within the area. A release site
can be used multiple times. A site where a wolf is released is not expected to be necessarily
where the wolf will stay. See further discussion below.
● The highest quality habitat is generally large, contiguous areas of public lands with a high
abundance of prey and low livestock densities. Consider where most big game are located
during the time when releases occur and where livestock are or will be in relation to big game
during other seasons. Regardless of where wolves are released, habitat selection may differ
greatly compared to habitat models.
● Release sites do not necessarily have to be federal lands. Consideration of overall landscape
context should inform the selection of release areas/sites.

Dispersal and homing tendencies of reintroduced wolves may or may not affect donor
population selection. The proximity of Wyoming to Colorado may lead to a higher potential of
wolves returning across state lines after being reintroduced. Dispersal studies reflect an average
dispersal from the release site being sixty to seventy miles but could vary significantly by
individual. Some TWG members suggested there is a northernly homing tendency; others
suggested wolves disperse in a starburst pattern, with no particular cardinal orientation.
Post-release dispersal is not comparable to natural dispersal; the average duration of dispersal is
five and a half months after release. Seasonal dispersal and seasonal migration patterns of prey
species such as wild ungulates will also affect dispersal of wolves.
It is important to consider the proximity of the release area to a state border. Release at least
seventy-five miles from a state border should be considered. This buffer should also be
considered for the borders of sovereign Tribal nations in Colorado, in consultation with these
Tribes; so that wolves do not immediately disperse to neighboring states/Tribal lands.
Especially under the conditions of a hard release, not much attention needs to be paid to
territoriality. Consider release sites that can support several packs to create a small population
that supports reproduction and the sustainability of the reintroduced wolf population. Avoid
creating widely dispersed, isolated packs to improve connectivity. Clusters of packs will help to
avoid poor survival and recolonization trends.
Interactions with human populations should be considered, and large populated areas should be
criteria for exclusion of release sites and areas. A flexible pace outlined below can also help to
address issues as they arise.
Wolves can succeed anywhere with adequate habitat where there is social acceptance; consider
findings from an in press (as of 8/2021) landscape analysis to inform the social and human
considerations for release sites and areas. Due to dispersal, where wolves settle may be far
away from the release location; consider social and topographic factors where wolves might
pass through during dispersal when selecting release sites and areas.

Number of release sites (and number of release areas)
Alternatives considered: Flexibility in specific release sites for an area with multiple release points;
multiple release areas; and one release area
Summary of TWG feedback: All alternatives were determined to have technical merit. The alternative to
have flexibility in specific release sites for an area with multiple release points is most preferred.
Rationale/discussion:
● Consider the number of release areas vis a vis the number of wolves reintroduced. It is likely
that not many release areas will be needed in Colorado to ensure wolf population growth.
Flexibility between a few (e.g., one to four) release areas would be prudent, with the option to
return to the same area or areas to release wolves over the course of several years. Adaptive
management will allow refinement of reintroduction logistics and technique year-by-year.
● A minimal number of release sites, such as a one or two logging roads, could serve to meet the
goals of reintroduction in a short period of time with minimal logistical complications.

Use of a higher number of areas and release of wolves in largely geographic dissimilar and
dispersed locations complicates the likelihood that wolves will encounter one another and begin
breeding. It is therefore not desirable to have too many geographically diverse release areas.
o If wolf population growth proceeds in Colorado like it did in the NRM following those
reintroductions, most of Colorado would be occupied by wolves within about ten years.
Reducing the social or geographic burden on specific release sites by distributing these
areas is only a consideration for a few years before wolves spread out on their own.
o If the wolf population in Colorado does not grow following the translocation as fast as
occurred in the NRM, there would be an opportunity to establish additional release
areas or sites as appropriate to meet recovery goals.
Alternatively, all wolves could be released in one area, at multiple sites to provide for security
and flexibility.
Lessons from other states include:
o When combined with natural recolonization into northwestern Montana (as is currently
occurring in northwestern Colorado) beginning in the 1980s, two release areas were
used in the northern Rockies in the mid-1990s. Within ten years of those releases, much
of the suitable habitat in Idaho, Montana, and Wyoming was occupied, and within
twenty years wolf populations had become established in Washington, Oregon, and
California, all based on these two release areas.
o To better understand the terminology used, Yellowstone National Park is a large release
area with multiple (six) release sites.
o The human population density of Colorado should play a role in informing the number
of release areas and sites.

Pace of wolf reintroduction
Alternatives considered: About thirty to forty- wolves reintroduced for one year (Fast); about ten to
fifteen wolves reintroduced per year for two to three years (Medium); about five to ten wolves
reintroduced per year for three to six years (Slow), be flexible (Note: numbers are not concrete, and are
meant to suggest relative pace)
Summary of TWG feedback: All alternatives were determined to have technical merit. The overall goal is
ultimately to establish a self-sustaining population. The goal of the initial translocation and restoration is
to introduce enough wolves at an adequate pace to establish a growing population that can ultimately
achieve a self-sustaining population. Without specifying what that might look like from a numerical
perspective and/or other indicators, there are a variety of ways (i.e., paces) that could work to achieve a
growing population. The general technical preference is for a “medium” pace, followed by a “slow”
pace, and, least favorably, a “fast” pace. It is important to be flexible and adapt the specific logistics of
these paces according to conditions of the reintroduction. It is also important to be adaptive around
specific dates and numbers. Note: Discussion of this topic focused specifically on the number of wolves
actively reintroduced, not long-term population goals or management thresholds. The latter will be
addressed at a future meeting(s).

Technical Working Group (TWG)
to Colorado Parks and Wildlife (CPW)
November 2021
Final Report on Restoration Logistics
Rationale/discussion:
● A medium pace is an appropriate balance between the need to reach critical mass and a
maintain a feasible pace to reach critical mass. It is important to employ adaptive management
strategies and robust monitoring to maintain the flexibility of reintroduction efforts, to be
nimble to adapt to the constraints around capture, and to monitor the success of release. Public
support may also be garnered by approaching reintroductions with a moderate and flexible
pace.
● Rationale against a slow pace of reintroduction is that the population may not reach critical
mass to achieve a growing population under this pace. The vulnerability of recently reintroduced
wolves to illegal human-caused mortality may be an additional impediment to reaching critical
mass. Colorado has smaller tracts of public land compared to Yellowstone and the NRM region,
which may enhance susceptibility to illegal mortality. A slow pace has a higher likelihood of
program failure than does a medium pace.
● A fast pace may not be logistically feasible (see capture considerations above) and the
complicated logistics associated with a fast pace may also lead the program to a premature
failure.
● Much of the discussion around pacing revisited topics of capture methods (see above) as well as
considerations for release areas and sites. Coordination of capture efforts with release sites is
important; the pace of release may be constrained by efficiency of capture.

When to stop and/or pause reintroduction
Alternatives considered: After about forty animals have been moved; indication of pack establishment;
indication of pack establishment with some documented reproduction; two packs raising two pups for
two consecutive years; flexible approach: i.e., do releases (e.g., of thirty to forty wolves) and then pause
to see what happens
Summary of TWG feedback: All alternatives have technical merit. The preferred option is to do ‘a
bunch’ (undetermined number) of releases (e.g., release a total of approximately thirty to forty wolves),
then pause, assess, and adapt based on whether the initial restoration phase has resulted in an
adequately growing population that will ultimately achieve a self-sustaining population. Note: This
discussion is focused specifically on when to pause active reintroduction, not on long-term population
goals, definitions for self-sustaining populations and long-term success, or management thresholds.
These latter topics will be addressed at a future meeting(s).
Rationale/discussion:
● Adaptive management is important: generally, it is recommended to release some number for
two to three years, pause, and then monitor and model population growth to determine
trajectory toward a self-sustaining population, and adaptively manage based on that model.
● The parameter of ‘when to stop reintroduction’ is not the same as the definition of a ‘selfsustaining population,’ but is rather a benchmark toward achieving that goal.
● It is important to predict and monitor a rate of growth and conduct analysis between rate of
growth and the overall status of the population.

Experiences in other states can inform the approach; however, adaptive management and
flexibility to learn and respond to what happens in Colorado is key.
TWG members have a variety of perspectives on topics related to ‘when to stop reintroduction.’
In addition to the general feedback of the group (above), additional individual perspectives are
provided below:
o There was discussion around the definition of a pack; some define it as at least a pair of
wolves; others define it as a pair of reproducing wolves with a litter. In the Northern
Rockies, a breeding pair was defined in the recovery plan as a pair that recruited at least
two pups through the end of the year.
o There is no reason to pause before thirty to forty wolves are released over the course of
twelve to eighteen months: data are adequate to support the pause with a more
minimal approach.
o Recognize that a pause in reintroduction might lead to a stop, given a monitoring
program to track population growth after two to three years.
o A pause should occur when the reintroduction target of approximately thirty to forty
wolves (released at a ‘medium pace’ of approximately two to three years as described
above) is achieved to assess whether the population is growing at an adequate rate
toward a self-sustaining population and if wolf-livestock conflicts can be managed
successfully in the areas where wolves become established. In general, some ambiguity
is needed to allow for the flexibility required by adaptive management; objectives
should not be overly restrictive to prevent adaptation to experiences and/or conflicts
during the reintroduction phase. Arbitrary numbers for defining the number of wolves
to be reintroduced or when to pause reintroduction should be avoided as they could be
limiting or create problems for adaptive management later.
o Each reintroduction effort’s population growth is different; it is possible that the
Northern Rockies is the best model to follow to determine models for Colorado’s
population growth. In Oregon, from a population of fourteen wolves, the population
doubled every two years for the first five years. Mexican gray wolves were released
from captive stock and repopulation dynamics were considerably different than in the
Northern Rockies and are still releasing twenty years after initial reintroduction.

Final Summary of Technical Considerations on
Compensation for Wolf Damage to Livestock
February 2022
Background &amp; Purpose
The document summarizes the Wolf Restoration and Management Plan Technical Working Group (TWG)
discussions regarding technical considerations of potential components of a livestock damage
compensation plan. ‘Technical considerations’ in this context include perspectives on biological
relevance, ability to quantify and/or measure, impact on technical outcomes, feasibility for managers,
and experiences with and/or in implementing programs in other states. This document is intended to
help provide background to inform discussions regarding a Colorado compensation plan for wolf
damage to livestock.
This document is not a comprehensive set of recommendations on a complete compensation plan. The
TWG recognizes that there are various social considerations for livestock compensation that the
Stakeholder Advisory Group (SAG) has discussed, and that the SAG was charged with leading the
development of comprehensive recommendations regarding the compensation plan.

Contents
Eligible Damages: Technical considerations for confirmed depredation; probable depredation; missing
livestock (including compensation ratio/multiplier, minimum acreage requirements, and public and
private land considerations); indirect loss; pay for presence

�Eligible Damages
Confirmed depredation
Background: To confirm a depredation, CPW uses a "Preponderance of Evidence” standard;
documentation by the claimant necessary to support a claim for damage can include “tangible evidence”
such as photographs, scat, tracks, attack and feeding characteristics, puncture wound spacing,
hemorrhaging, etc.
Summary of TWG feedback: Compensation for confirmed depredations at fair market value has
technical merit.
Discussion and rationale
● TWG members emphasized the importance of timely and skilled investigation to confirm a
depredation. They noted that the presence of scat and tracks alone are not technically sufficient
to confirm a depredation. Because wolves are also scavengers, their presence at a carcass is not
enough to confirm that they killed the livestock.
● TWG discussed that probable losses, missing livestock, and/or indirect costs associated with
confirmed wolf depredations could provide technical merit for compensating more than 100%
for the confirmed loss. Discussion of these topics, including discussion of multipliers and
compensations ratios, is detailed below.

Probable depredation
Background: CPW currently does not have a definition for ‘probable loss,’ and rather uses a
preponderance of evidence standard. Different states apply different definitions of ‘probable’ loss. An
example definition for "probable" loss based on USDA APHIS/Wildlife Services includes the presence of
some evidence to suggest possible predation but a lack of sufficient evidence to clearly confirm
predation by a particular species. A kill may be classified as probable depending on factors including but
not limited to recent confirmed predation by the suspected depredating species in the same or a nearby
area, recent observation of the livestock by the owner or the owner's employees, and telemetry
monitoring data, sightings, howling, or fresh tracks suggesting that the suspected depredating species
may have been in the area when the depredation occurred.
Summary of TWG feedback: Compensation for probable depredation has technical merit. A range of
compensation amounts (50-100% of fair market value) were suggested as having technical merit,
however lesser amounts (i.e., less than 50%) were not suggested.
Discussion and rationale
● Criteria of probable depredation
o Clear definition of probable depredation is important for managers in administration of
the program and for producers in understanding the program.
o U.S. Department of Agriculture Animal Plant Health Inspection Service – Wildlife
Services (USDA APHIS-WS)’s definition of probable losses has been adapted by the
states that have adopted probable depredation compensation models. Consultation
with other states regarding their experience around probable losses is advised.

�In some states, the incidence of compensation for probable losses was initially high but
has waned over time, due to the increased knowledge and experience of investigators
over time. With this experience, there is likely to be a decrease in the number of
incidents classified as probable losses, and thus a decrease in compensation paid for
probable losses.
o It is important to define whether/what secondary management actions are triggered by
a ‘probable depredation’ designation, as well as whether a ‘probable depredation’ can
trigger a multiplier or compensation ratio (see below).
Compensation amount
o Compensation at 50-75% of fair market value were suggested to be economically
feasible and adequate for probable depredation. Higher amounts (i.e., 100% of fair
market value) were also seen by many as having technical merit as well as potential
social merit in increasing social tolerance.
o Different payment amounts for confirmed vs. probable depredations could complicate
use of a multiplier if both kinds of losses trigger a multiplier (see below).
o Compensation for probable losses at a different rate than confirmed losses may also
complicate management of the compensation program and potentially could make the
claims process more onerous for producers.
o

●

Compensation ratios/Multipliers
Background: The TWG considered the potential for use of a compensation ratio or multiplier to address
missing livestock and/or indirect losses. The TWG considered use of a compensation ratio on public
versus private lands, the value of the compensation ratio, and minimum acreage required, if any, to be
eligible for compensation ratios.
Summary of TWG feedback: Compensation ratios for both cattle and sheep on public and private lands
have technical merit, but there are different perspectives and technical considerations regarding when
these ratios should be triggered and how they should be administered. TWG members generally were
uncertain as to what an appropriate ratio should be. Technical considerations for and against minimum
acreage requirements include consideration of total leased lands, use of penning versus open range
grazing, and other factors.
Discussion and rationale
● There is significant complexity in considering how to fairly apply a multiplier or compensation
ratios.
● Frequency of missing livestock occurs at different rates depending on the age and type of
livestock, spatial and temporal factors and differences in producer practices, such as regularity
of cattle checks and detection rates.
● Compensation ratios may be more likely to be used in situations where locating depredations is
more challenging and for livestock that are more vulnerable to depredation (i.e., calves and all
sheep). Patterns of depredations observed in other states could be useful to constrain criteria
for compensation ratios to only include certain ages or types of livestock.
● Compensation ratios could be employed with spatial considerations. However, this would be
complex to implement.
● Variation in detection rate between producers, uncertainty in cause of death (such as due to
another predator), and lack of well-documented trends lends to the importance of management
discretion if a multiplier is to be employed.

The use and value of a compensation ratio could also consider other factors such as
implementation of conflict reduction cost-share programs or pay for presence programs.
Compensation ratios may incentivize regularity of cattle checks but may also disincentivize
conflict risk reduction solutions and improved management practices, as well as impede
management of wolves similarly to other predators in Colorado.
Minimum acreage requirements may lend managers flexibility for best management decisions,
but number of missing livestock may also be a better criteria. Minimum acreage requirements
are complicated by land use and ownership issues, such as livestock producers leasing multiple
small acreage parcels. Further, current game damage program criteria do not distinguish
between various types of operations (e.g., producer vs. hobbyist); acreage requirements may be
confusing and create arbitrary distinctions for eligibility that may be inequitable.
o For example, minimum acreage requirements could refer to the total area within which
a livestock herd experiencing depredations is grazing. The idea would be to offer a
compensation ratio for livestock depredations that occur in herds that are grazing a vast
area, such that documenting additional depredation events would be difficult even if
additional individual livestock are missing. Conversely, compensation ratios might not
be applied when depredations occur in smaller pastures in more controlled settings,
where detecting depredations is easier.
o Terrain and vegetation characteristics may also be considered when determining
whether and how to apply a multiplier for large tracts of lands where missing livestock
are more difficult to find.
Range cattle producers by the nature of their operations and large scale of acres being grazed
will have difficulty participating in any compensation program since they infrequently become
aware of depredation events that allow timely submission of documents to CPW.
o Multipliers typically require having verified losses; it is more difficult to verify losses for
cattle than for sheep and thus it will be more difficult to apply a multiplier or
compensation ratio to cattle.
o Given this challenge, alternatives for compensating for missing cattle, other than
multipliers, should be considered. Criteria such as animals put on grazing allotments, the
difference in animals collected at end of the grazing season and known presence of
wolves on the grazing allotment may be appropriate to consider for missing cattle.
o Multipliers may not be appropriate for all calving on open range because of the difficulty
of distinguishing whether calving was successful vs. whether calves were lost to
depredation. However, not all producers have a choice as to whether or not they calve
on open range.
From a technical perspective, size of pasture or rangeland is important in impacting detection of
confirmed, probable, and missing livestock.
Land ownership (public vs. private) is a social consideration rather than a technical consideration
for compensation.

Indirect losses (Also referred to as production losses by the SAG)
Background: Indirect losses are those associated with economic impacts other than death of livestock.
Types of indirect losses considered: Pregnancy rates, weaning rates, lower weight gain due to stress
or increased activity rates, future economic losses (for example, loss of future production or loss of
investments in genetics), other losses.

�Summary of TWG feedback: The TWG noted the technical reality of indirect losses such as those
considered above but also noted that many factors can contribute to indirect losses. There was mixed
feedback on whether there is technical merit to compensate for indirect losses, particularly as there is
not a clear or proven technical approach for quantifying and compensating for indirect losses.
Discussion and rationale
● Reduced summer weight gain and other indirect losses can be subject to external factors
beyond wolf depredation – for example, spatial or interannual variability in weather and forage
production, other predation, and effects of other land use pressures such as recreation on
public lands. It can be difficult to separately determine or fairly compensate indirect loss due to
effects of wolf-livestock interactions.
● There is a lack of a concrete scientific body of research on indirect losses and conflicting
anecdotal information. Documentation of indirect losses varies between producers.
● Indirect losses could be compensated through a multiplier or compensation ratio. If allowing
compensation for indirect losses separate from a multiplier, stringent documentation and
confirmation criteria are important to prevent abuse. In one state that allows compensation for
indirect losses, the process is cumbersome and complex for producers. Currently, there is not a
consistent approach among states, nor technical consensus on an approach for quantifying and
compensating for indirect losses apart from using multipliers for confirmed losses.
● Multipliers have served to reduce social conflict in some places.
● The TWG recognized that there are also social considerations regarding compensation of
indirect losses. A member noted that there are social science studies that indicate that wolf
restoration would be better received if indirect losses were acknowledged and accounted for.
● Availability, or lack of availability, of lethal management tools to reduce indirect losses is also a
consideration for whether to compensate for indirect losses.

Pay for presence program
Background: Pay for presence programs provide compensation for presence of wolves on lands used for
livestock production, regardless of whether there is confirmed, probable, or indirect loss.
Summary of TWG feedback: The TWG offered a variety of perspectives regarding feasibility, purpose,
and efficacy of a pay for presence program, without clear consensus on whether or not such programs
have technical merit.
Discussion and rationale
● Pay for presence programs can help to recognize and value the benefits of private landowners in
providing wildlife habitat, migration corridors, carbon sequestration, watershed health, and
recreational opportunities. Additionally, implementation of a pay for presence program may be
a simpler way to address indirect losses and/or probable depredation.
● Pay for presence programs were implemented to minimize illegal killing of wolves to assist in
and benefit species recovery, as it was employed to do in the Mexican gray wolf recovery effort
in Arizona and New Mexico, but may not lend to conflict reduction.
● Potential drawbacks of a pay for presence program include inconsistency of treatment of wolves
vs. other predators, funding constraints and monitoring requirements. Similarly, paying for wolf
presence on private land may lead to paying for presence of other wildlife species, or at least

landowners questioning why this is not the case, which could lead to more expense and
distribution monitoring needs for other species.
Actual damage may not justify pay for presence, with spatial and landscape factors such as
vulnerability of livestock and location of dens and range geography more greatly informing
depredation patterns than presence of wolves.
To properly distribute available funds, this program may also require a greater degree of
monitoring, which may constrain agency flexibility to allocate time and staffing resources to the
development and deployment of conflict risk reduction tools.
Pay for presence would create an additional financial burden.
Pay for presence may also disincentivize producers to adopt conflict minimization practices,
while not reducing conflict between wolves and livestock.
The funding constraints of compensation, in addition to the staffing and capacity constraints
indicated above, may also prevent management flexibility and ability to compensate for
confirmed, probable, or indirect losses.
One consideration for initial restoration is to compensate producers through a pay for presence
program near and around a certain radius of release sites. It would need to be determined
whether such compensation would be for a certain amount of time following release, or
indefinitely. It would be difficult to determine the appropriate radius or amount of time for
which to do this , and could create administrative challenges as well as concerns over fairness
for producers falling just outside of temporal or spatial boundaries to qualify for the program.

Administration and Funding
Damage investigations
Background: CPW conducts most game damage investigations in the state. Some verification is also
conducted by USDA APHIS-WS.
Summary of TWG feedback: Conducting damage investigation via CPW and APHIS-WS has technical
merit. Investigators should have adequate training to conduct professional, consistent damage
investigations.
Discussion and rationale
● A central consideration for investigative authority is adequate training. Both CPW and APHIS-WS
staff are well-trained and trusted in local communities to conduct damage investigations.
Investigation training courses could be offered on a regular basis to ensure investigators stay upto-date on investigation practices.
● Regardless of the compensation formulas used, key to a successful compensation program are
unbiased field investigators providing honest and accurate assessments.
● While the TWG generally did not see technical merit in the use of other potential investigative
bodies, they noted that there may be other social values in having local officials accompany
professional investigators and livestock producers and/or landowners during damage
investigations.
● It will be important to depoliticize damage investigations as much as practical. In some highly
politicized or controversial investigations, USDA APHIS-WS could serve as a sort of “third-party
neutral,” which would help to protect relationships between state officials and local

communities. However, different agencies may be viewed differently by various stakeholders.
Consistency of approaches within the state is important to build trust between the agencies,
and among agencies, livestock producers and the public.
Communication of investigation standards to impacted parties should be a priority, and local
individuals should be equipped with the appropriate knowledge and tools to navigate the claims
process. A valuable purpose of public and stakeholder engagement is in increasing knowledge of
how to 1) protect the scene of a potential depredation so an investigation may be conducted
with minimal contamination and 2) follow the appropriate steps to successfully file a claim for
compensation if a wolf, or other large predator, were determined to be the cause of the
depredation.

Funding sources
Background: CPW’s Game Damage Program is funded by the appropriation of sportspeople’s dollars
from the Wildlife Cash Fund. HB21-1243, passed during the 2021 Colorado legislative session, prohibited
use of wildlife cash funds generated from the sale of hunting and fishing licenses or from associated
federal grants to fund the program implementation and administration of the restoration and
management of gray wolves.
Summary of TWG feedback: TWG perspectives generally support using multiple sources of funding for
compensation and other livestock interactions issues, although there were varying perspectives on
whether this is a technical issue and/or is an issue with technical merit. Consistency in administration of
funds, regardless of sources, was emphasized.
Discussion and rationale
● Maintaining reliability and consistency of funding are common considerations. Donations and/or
funding from external sources such as NGOs should be considered from these perspectives.
● While some suggested a decentralized funding paradigm could support localized management
strategies, others strongly discouraged management priorities and administration of funding to
be set by any agency other than CPW and the Parks and Wildlife Commission.
● In some other states, the Department of Agriculture is responsible for administration, however
Colorado statutes are clear that this responsibility lies with CPW. Use of sources that are already
allocated for other special interests, such as license plates or tax checkoffs, would potentially
dilute already limited funding.
● Some encouraged maintaining the status quo regarding funding for other species; others
suggested wolves may imbalance current financial frameworks.
● Difficulties in obtaining and maintaining federal funds were noted.

Administration
Background: CPW is currently the sole administrator of reimbursement for game damage.
Summary of TWG feedback: The importance of consistency of funding administration was common
feedback. The pros and cons of using other agencies as administrators for funding and/or for other
elements of the game damage program was also discussed.

�Discussion and rationale
● Other states’ funding administrators include state departments of agriculture and/or livestock,
local government, and federal government.
● Political agendas, public and private special interests, and trust in administrators were recurring
concerns regarding multiple administrators.
● Use of a sole administrator offers simplicity, transparency, and ease of access to members of
the public.
● Coordination between state and federal wildlife agencies should be considered to anticipate
potential relisting of the gray wolf and its implications for game damage compensation and
management.
● Local NGOs and coalitions may have roles to play in funding, stakeholder engagement,
information dissemination, training and promotion of conflict risk reduction tools, and
communication to inform agency best management practices.

CPW’s current game damage program
Background: CPW reimburses for damages caused by big game species to livestock. Wolf damage to
livestock is currently included under this program; CPW is considering updates to the program
specifically for wolves. Additional information about the current program is linked from the CPW

Summary of TWG feedback: There are various considerations for whether and how the current program
should be evolved specifically for wolves. There is general consensus regarding the value of consistency
of process, however there are a variety of opinions on whether there should be differences in
compensation eligibility, amount and/or criteria. Many TWG members suggest technical merit in
consistency in using the existing program, however the TWG also recognizes that there are various social
considerations on this topic as well that the SAG will weigh in regarding whether and how the current
program should be evolved for wolves.
Discussion and rationale:
● If the current program is effective and well-respected, there is value to both livestock producers
and wildlife managers in consistency of approach to game damage across different species of
predators. At the very least, consistency of the process used streamlines ease, access,
timeliness, and administration. There are technical arguments as well for treating all predators
similarly rather than differentiating wolves as unique from other predators.
● The wolf restoration effort could be an opportunity to make improvements to the current
program, such as incorporating incentives for non-lethal conflict prevention or minimization
tools.
● As wolves are currently a state and federally-protected species, livestock producers may not
have the same management tools available for wolves as for other predators such as bears and
lions. If the program changes over time, including based on listing status and available
management tools, changes in the compensation program might be appropriate. Any changes
should be clearly communicated to the public.
● Generally, for compensation programs for wolves throughout the West, “burden of proof” is
often a primary reason for producers to find a compensation program unsatisfactory. Clarity of

who investigates, how investigations occur, and how to make the claims process more
accessible and efficient for producers are key components of a successful compensation
program.
The TWG anticipates that there are a variety of social considerations that the SAG might discuss
affecting whether and how compensation amount, eligible expenses, and/or other criteria
should be modified for wolves as compared to the current program.

Non-lethal conflict risk reduction
Feedback on practices and programs
Background: Non-lethal conflict risk reduction techniques are employed to prevent livestock conflict,
and include strategies such as management intensive grazing, livestock guard dogs, carcass
management, riders and herders, fladry, scare devices, high risk landscape management, and herd
composition.
Summary of TWG feedback: Adoption of non-lethal conflict risk reduction techniques by livestock
producers in Colorado is important to the long-term success of the wolf restoration and management
program. Their effectiveness is context-specific and not well quantified. Various considerations for how
to disseminate and facilitate adoption of conflict risk reduction techniques were also discussed. Note:
This report does not address lethal management for conflict risk reduction.
Discussion and rationale
● The adoption of conflict risk reduction techniques by producers as both a proactive and reactive
(post-depredation) approach to livestock conflict will be important to the long-term success of
wolf management in Colorado.
● Experiences with livestock producers in other states also suggests that incentivizing and allowing
creativity in conflict risk reduction approaches and working with producers is an effective
approach.
● Context-specific considerations for effectiveness and feasibility of use of conflict risk reduction
techniques include livestock type, age, time of year, land size, other land uses, landscape
conditions, and local geospatial features, among other considerations that may impact livestock
operations and wolf predation behaviors.
● Quantifying the effectiveness of various non-lethal tools is difficult and research in this area is in
development, suggesting effectiveness is highly context-specific and requires some trial.
● The effectiveness of translocation of conflict wolves may vary, and some landscape conditions,
independent of individual predator or pack reputation or conflict minimization, may create
conflict hotspots.
● Suggestions for dissemination of non-lethal tools included building upon and/or leveraging
relationships with members of the agricultural community, including through agency outreach
(CPW, USDA APHIS-WS, and/or Colorado Department of Agriculture), community collaboratives,
NGOs, stakeholder groups and livestock producer associations, rancher-to-rancher engagement
and training programs, academic programs such as Colorado State University Extension, and
conflict risk reduction cooperatives.
● Providing funding support, either directly or through cost-share programs, may help to foster
adoption of techniques.

�Non-Lethal risk reduction requirements for compensation
Background: The TWG discussed technical considerations regarding requirements that non-lethal risk
reduction techniques be used prior to depredation to be eligible for compensation.
Summary of TWG feedback: TWG members emphasized the importance of encouraging non-lethal risk
reduction techniques, however there were various perspectives regarding the technical merit and
feasibility of requiring their use in order to receive damage compensation. The TWG discussed contextspecificity of non-lethal risk reduction practices and losses, importance of maintaining flexibility rather
than prescribing practices, difficulty in defining risk reduction requirements, value in strategies to
incentivize adoption and creative problem solving, and maintenance of relationships with local
producers.
Discussion and rationale
● As stated above, the context-specific effectiveness of non-lethal conflict risk reduction tools may
suggest that the requirement of techniques may not always lend to conflict reduction, and
flexibility in tool use should be prioritized.
● Questions around the assessment burden on agency staff, what should be required, and how
conflict risk reduction should be assessed and regulated arose as important considerations.
● Requirement of non-lethal risk reduction techniques may also shape the technical and social
value of these tools: some producers may simply use them to fulfill the requirement, while
others may invest a lot of time and effort into conflict reduction. This variability complicates
implementation of risk reduction requirements.
● Some producers will likely view additional requirements to be another unfunded mandate,
which may strain or harm relationships between local agency officials and producers.
● Whether or not non-lethal conflict risk reduction techniques are required for compensation,
development of programs to alleviate the financial burden on producers and foster the adoption
of techniques may be more effective to achieve conflict reduction.

�Appendix A: About the Technical Working Group
The purpose of the Technical Working Group (TWG) is to review objective, science-based information as
well as provide its own knowledge and experience at the state/federal/tribal level to inform the
development of the Colorado Wolf Restoration and Management Plan. The TWG is composed of
members who bring experience in wolf reintroduction, wolf management, conflict minimization,
depredation compensation, and other relevant topics. CPW is responsible for writing the Wolf
Restoration and Management Plan. The Parks and Wildlife Commission (PWC) serves as the decisionmaking body responsible for approving the Wolf Restoration and Management Plan. The TWG serves in
an advisory capacity to Colorado Parks and Wildlife, offering non-binding input into the development of
plan content. The TWG is not a decision-making body and has no authority on wolf management policy,
research, or operations. The TWG operates by consensus. For purposes of the TWG, consensus refers
specifically to general agreement, or lack of objection, that an option or alternative has sufficient
technical merit to be recommended for consideration by CPW. In the absence of consensus, dissenting
views will be documented.

�Colorado Wolf Restoration and Management Plan
Technical Working Group (TWG) to Colorado Parks and Wildlife (CPW)
Final Report on Technical Recommendations for
Colorado State Listing/Delisting Thresholds and Phasing
May 2022

Background &amp; Purpose
This document summarizes the Wolf Restoration and Management Plan Technical Working Group
(TWG) recommendations regarding population recovery thresholds for downlisting and delisting gray
wolves from the state endangered species list in Colorado. As of February 10, 2022, wolves are listed
under the Federal Endangered Species Act as Endangered. This effort does not replace a federal
recovery plan, nor does it outline federal recovery goals. This effort describes state management of a
species for when management authority is returned to the state (i.e., federally delisted). This effort may
inform development of federal rulemaking processes in the interim, in particular consideration of
development of a 10(j) Experimental, Non-Essential designation.
The thresholds were developed through expert deliberation of TWG members and are presented in a
phased framework. While the determination of these thresholds is a technical exercise, management
actions corresponding to the phased framework should be informed by legal and social considerations,
which will be addressed largely by the Stakeholder Advisory Group (SAG). The framework is presented
below (page 2) and is followed by a summary of TWG discussion and rationale.
Colorado State definitions for state endangered and threatened species are as follows:
● Endangered Species (CRS 33-1-102 (12)): any species or subspecies of native wildlife whose
prospects for survival or recruitment within this state are in jeopardy as determined by the
commission.
● Threatened Species (CRS 33-1-102 (44)): any species or subspecies of wildlife which, as
determined by the commission, is not in immediate jeopardy of extinction but is vulnerable
because it exists in such small numbers or is so extremely restricted throughout all or a
significant portion of its range that it may become endangered.

�Notes on framework:
*Phases will be dictated by numeric and temporal wolf population thresholds described in the table.
While it is intended that state status will also correspond to these thresholds, there may be a time lag as
the Parks and Wildlife Commission undertakes the procedural process to change the state status based
on population counts.
**Minimum population counts in any phase include gray wolves that have been reintroduced to
Colorado and those that have naturally migrated into the state and their progeny. Wolf population
minimum counts in this table refer to counts conducted in late winter to most accurately reflect
recruitment.
***“Successive” means years in a sequence, with any number of gaps in between. Consecutive means
years in a sequence with no gaps. The rationale for using a metric of successive years is to account for
potential years when an adequate survey cannot be conducted.
****Downlisting to State Threatened status may not occur until the four-successive year requirement is
met in the State Endangered status phase 1 (Phase 1). However, the two-successive year timeline for the
phase 2 minimum count requirement begins when the minimum number is first met and may occur
concurrently while in the Phase 1/endangered phase. Consequently, it is possible that delisting
(Conclusion of Phase 2) may occur immediately after Phase 1, should the Phase 2 requirements be met
concurrently during Phase 1.

�Discussion and Rationale
The TWG generally supports a phased approach to gray wolf downlisting, delisting, and management:
●
●
●
●
●
●

It provides clarity for current and future management while supporting the statutory goal of
managing for a self-sustaining wolf population.
It can allow for increasing management flexibility as the wolf population increases, as well as for
flexibility to manage conflict throughout all phases.
Other states have similarly used phased approaches to managing their wolf populations.
It is important to maintain public trust in CPW in each phase of restoration and management by
being responsive to current and future conditions of conflict, social conditions, and wolf
population trends.
Thresholds for phasing are based on best available science and meet all requirements under
state statute.
Some members suggested that linking the specific population metrics, rather than state listing
status, to management options would lend to more management flexibility – particularly if
delisting actions are tied up in litigation when the population hits the corresponding population
metric. However, others suggested linking listing status directly to management phases would
simplify messaging and expectations for field staff and members of the public. The difference in
management options currently allowed under State law for endangered and threatened listing
statuses is relatively inconsequential. The framework suggests that the population metrics
should correspond with state status, but they are not directly linked: it is expected that once the
wolf population reaches the metrics defined for downlisting/delisting, the management
flexibility defined by the subsequent phase will be immediately in place, while at the same time
the Colorado Parks and Wildlife Commission undertakes the processes to take the necessary
action to down/delist the species. There may be a procedural delay when moving from Phase 2
to Phase 3.

The TWG generally supports minimum population count with a temporal threshold to downlist wolves
from state endangered to state threatened and to delist wolves.
●

Rationale for recommendation of minimum population count as the relevant metric for
downlisting and delisting:
o The social behaviors and resiliency of wolf populations, specifically wolves’ tendency to
form packs and documented reproductive success, support a minimum population
count to satisfy the technical specifications of CRS 33-2-105.8 to restore a self-sustaining
population of wolves to Colorado.
o At the population level, the reproductive potential of a greater number of smaller packs
or a smaller number of larger packs does not significantly differ and thus supports
population counts rather than a minimum number of packs, although tracking pack
statistics may be useful to document population stability and growth.
▪ There are differing definitions of a ‘pack’ found in the scientific literature and in
different states’ management plans. In various contexts, a pack has been
defined as 2 wolves, 4 wolves, or a breeding pair and two litters from different
years.

o

Defining management thresholds around breeding pairs will be difficult and expensive
to monitor as the population grows.
Geographic distribution metrics were discussed as potential thresholds, but some
suggested that this may be at odds with Colorado’s 2004 wolf working group
recommendations to allow wolves that do not cause conflict to live without bounds.
A minimum count is recommended in the early phases of reintroduction. A minimum
count is more labor and resource intensive; however, it is beneficial for accuracy of
monitoring and both technical and social confidence in informing downlisting and
delisting decisions and management. Minimum population counts can be more accurate
at lower population sizes than they are at higher population sizes.
As the wolf population grows, minimum population counts are more difficult to conduct
and are less reliable for understanding total population size.
▪ As the wolf population grows larger, and upon transition to delisted status,
consider the use of a minimum population estimate and/or population models
as a more reliable metric, i.e., models based on distribution, vital rates, and
abundance estimates, etc.
▪ Minimum counts will be important to compare with population estimates
throughout phases 1 and 2, and population estimates can validate minimum
counts.
▪ Weather, staffing, and other unforeseen events can affect ability to conduct
minimum counts.

●

Rationale for temporal component to minimum population metric:
o A temporal threshold of multiple successive years after minimum population counts
were met in each phase was suggested as a measure of persistence in population
trends.
o Members suggested interaction between minimum population count and the length of
time could accommodate rapid or slow population growth. For example, rapid
population growth could eliminate the need for a temporal requirement between
phases.
o ‘Successive’ means years in a sequence, with any number of gaps in between.
‘Consecutive’ means years in a sequence with no gaps.
o Members suggested that a temporal requirement of successive minimum population
counts for downlisting are important to ensure a trend of a stable or increasing
population, to account for the potential temporary population increases that may occur
through reintroduction, and to allow for temporary fluctuations in population and/or
unforeseen monitoring challenges over time.
o Members suggested that review of State relisting (to threatened or endangered status)
should be initiated when thresholds are not met for two consecutive years; this allows
for potential temporary population decreases and/or unforeseen monitoring challenges
that may affect minimum count while also initiating timely review should counts fall
below threshold two years in a row.

●

Additional considerations for minimum population counts:
o Minimum counts for delisting are NOT intended as population objectives or
maximums.

�o

o
o

In recommending specific minimum population counts for downlisting and delisting, the
TWG cited wolf population trends, modeling efforts, other wolf recovery efforts,
literature review of population modeling, and criteria for phased management
elsewhere.
Minimum counts should include wolves that have naturally migrated to Colorado and
their progeny as well as those that were reintroduced.
While wolf monitoring occurs throughout the year, the wolf population minimum count
to inform downlisting/delisting decisions should be held in late winter to reflect
recruitment most accurately.

●

Considerations for spatial distribution and ecological niche:
o The social and spatial tendencies of gray wolves suggests that 150-200 wolves would
distribute among several million acres of territory in Colorado; spatial occupancy can be
estimated based on literature regarding pack and territory size.
▪ Minimum population count as a metric for State downlisting and delisting is
thus correlated with spatial distribution.
o Spatial distribution, ecological function and the 3Rs model (representation, redundancy,
resiliency) are important considerations and goals for conservation.
▪ Given the large-scale movements and natural history of wolves, the 3Rs
approach is more relevant for larger or range wide conservation (i.e.,
throughout all the Lower 48 contiguous United States); however, it is less
relevant at the scale of Colorado for state reintroduction and down/delisting
metrics.
o Positive ecological effects from having wolves on the landscape can occur, however they
are difficult to quantify and document, require appropriate scale, and are also situationspecific.
▪ Ecological effectiveness is a vague concept and situation-specific; for example,
positive effects of a full complement of large carnivores in Yellowstone may not
apply in other areas.
▪ Ecological effectiveness and trophic cascades across a large area do not fully
occur until there is a saturated wolf population. However, social carrying
capacity and conflict in human-dominated landscapes will impact pack size and
distribution and will likely limit achievement of ecological carrying capacity.
▪ Landscape level ecological effects are thus both difficult to quantify and
to achieve and are not appropriate as a metric or criteria for State
downlisting and delisting.

●

Considerations for connectivity:
o Measures of genetic health and/or connectivity, such as measuring adequate
heterozygosity from blood or tissue samples, are important metrics that should be
periodically monitored over time as an indicator of a self-sustaining population.
o Indicators of genetic connectivity are not necessary as a threshold for State downlisting
and delisting. If wolves from the Northern Rockies or Pacific Northwest are sources for
reintroduction, and wolves continue to disperse into Colorado from neighboring areas,
the genetic makeup of Colorado wolves will already reflect the genetics of these areas.
Colorado’s wolf population is demographically connected to other populations in the
Northern Rockies. Colorado thus does not require higher numeric population
downlisting/delisting thresholds set for other locations that lack spatial connectivity.

�●

Considerations for species reclassification and management after wolves are delisted:
o As noted above, connectivity is an important indicator for long-term monitoring, as it
contributes to a self-sustaining population.
o Reclassification of gray wolves from nongame to game status would be a phase
discretionary to the Colorado Division of Parks and Wildlife, rather than a prescribed
phase. Reclassification to game species is not legally required nor discussed by statute
CRS 33-2-105.8.
o Determination of whether to move to game classification should include consideration
of social input regarding acceptability of wolf harvest and means of take, demand for
population size management, livestock conflicts, impacts on other wildlife populations,
other impacts from conflict, and/or demand for harvest opportunity. Many game
populations in Colorado are managed to achieve a population size or trend objective,
which will be an important consideration when this determination is made. There are
advantages to early discussion on this topic; however, learning will also occur over time.
o There should be clarity on the objectives of reclassification, for example, more
liberalized management of conflict vs. management of populations though regulated
hunting.
o Consideration of reclassification should require maintenance of a minimum population
estimate greater than the delisting threshold, with a sufficient buffer to avoid the need
to relist.

�Colorado Wolf Restoration and Management Plan
Technical Working Group (TWG) to Colorado Parks and Wildlife (CPW)
Final Report on Technical and Experiential Feedback on
Wolf Management Considerations
August 2022
Background &amp; purpose
This document summarizes the Wolf Restoration and Management Plan Technical Working Group
(TWG) discussions regarding technical and experiential feedback on a variety of wolf management
issues, including perspectives on biological relevance, ability to quantify and/or measure impacts,
impact on technical outcomes, feasibility for managers, and experiences with and/or in implementing
programs in other states.
This document is not intended as a literature review nor as a definitive set of recommendations
regarding wolf management in Colorado. Rather, it offers a consensus-based synthesis of key takeaways
from the TWG – based on its in-depth knowledge and practice of biological science and wolf
management – to help inform the wolf restoration and management plan that will be developed by
Colorado Parks and Wildlife.
The TWG recognizes that there are various social considerations for impact-based management that the
Stakeholder Advisory Group (SAG) has discussed in informing an impact-based management plan for
Colorado. A recurrent theme across many topics is to consider trust – including trust in managers,
messengers, and stakeholders – as an input for effective management, and conversely to consider how
to address lack of trust as a barrier to effective management.

Key takeaways
●

Conflict-centered management vs. objective-based management: Wolf management should
focus on management of conflict, with consideration of the social factors that accompany an
impact-based management approach. Lessons from other states with wolves suggest population
management is not robustly correlated with conflict minimization. Generally, the public has a
high expectation that state wildlife agencies will address wildlife related challenges.

●

Avoiding misinterpretation of maximum vs. minimum population metrics: It is important to
use clear and consistent messaging to reinforce the purpose of minimum population
counts/estimates, which are not intended as population objectives or maximums and have been
misinterpreted in other contexts.

●

Zonal management: Initial and long-term management should be impact-based. Zonal
management of conflict could be a consideration for future management. Delineation of zones
in the future could be informed by experience and data gathered through impact- (and conflict-)
based management, understanding of ecological and social suitability (inclusive of wildlife and
agricultural interests), and learnings from wolf dispersal and establishment on the ground.

�●

Wolf population self-regulation: Intrinsic self-regulation of wolves is unlikely at a statewide
scale; wolves will likely be extrinsically regulated particularly by social carrying capacity. Wolf
population self-regulation does not achieve the same goals as conflict management.

●

Positive impacts and wolf management: Positive and negative impacts can occur due to wolf
presence; positive impacts do not generally require hands-on management but can be
communicated through education and outreach and can inform management activities and
funding opportunities.

●

Non-lethal livestock conflict minimization: Adoption of proactive and reactive non-lethal
conflict risk reduction techniques by livestock producers in Colorado is important to the longterm success of the wolf restoration and management program. The effectiveness of these tools
is context-specific and not well quantified.

●

Post-depredation management of conflict wolves: While wolf depredations on livestock in
other states are uncommon and do not represent a notable burden to the livestock industry as a
whole, some wolves do cause significant problems for some ranchers and some areas
experience repeated and frequent wolf depredations on livestock. Management of wolflivestock conflicts following depredations should allow flexibility for managers; non-lethal and
lethal management techniques should be applied adaptively and are context-specific. To be
effective at reducing further depredation events, lethal and non-lethal responses for resolving
conflict should be applied quickly and properly. Relocation of depredating wolves has little
technical merit.

●

Lethal management of conflict wolves: Lethal and non-lethal management are both critically
important tools for conflict minimization; lethal management will likely attract greater social
attention. In evaluating the management approach on a context-specific basis, consider the
trade-offs among ability to target depredating wolves, conflict minimization efficacy, cost,
reproductive and recruitment success, wolf population size and listing status, impacts to
livestock producers, and social/stakeholder interests when considering lethal take options,
including incremental and whole pack removal.

●

Considerations for ecological effects: Ecological function is an important factor to consider but
is difficult to quantify and may be less relevant as a metric at the state scale.

●

Impacts of wolves to ungulates, big game, and big game hunting: Although statewide impacts
to ungulate populations and hunting opportunities have not occurred in other states and are
unlikely in Colorado, wolves can have local impacts to ungulate recruitment due to predation of
young ungulates. Wolves prefer elk and will also prey on deer and other ungulates; moose may
be targets of predation where they are abundant. Reduction in big game hunting opportunities
and targeted wolf control have sometimes occurred locally in other states to address negative
ecological or economic effects of reduced ungulate populations. Ungulate populations are
impacted by a complexity of interacting factors.

●

Impacts of wolves to prey compromised by infectious disease: Predators like the gray wolf may
select for prey compromised by infectious diseases, which could prove useful in reducing
infectious disease prevalence in ungulate populations, primarily when pathogens are directly

�transmitted among hosts. The strength of a potential disease reduction depends on numerous
factors, including specific disease etiology, the strength of selection for infectious individuals,
and overall predation rates. It is unclear whether wolves will have a measurable effect on
chronic wasting disease (CWD) in Colorado, where environmental contamination is likely to be a
primary transmission route and where CWD is already well-established in mule deer, a species
that wolves generally do not select for in the presence of elk.
●

Interactions with other wildlife species: Wolves are important components of trophic networks
where they are present on the landscape and their presence may have interactions with other
large carnivores. The presence of wolves will not have an impact on populations of threatened
and endangered species in Colorado, specifically lynx and Gunnison sage grouse.

●

Management of conflict with humans: Attacks by wolves on humans are exceedingly rare;
education and outreach for recreationists and other public lands users should include best
practices and guidance, including how to differentiate wolves and coyotes. Flexibility to address
rare instances of wolf habituation in areas dominated by humans is important.

●

Management of conflict with pets and hunting dogs: Wolf attacks on pets are uncommon;
education, outreach, and management should be used to proactively prevent conflict. It is
important that public messaging emphasizes the risks assumed when domestic and hunting
dogs are present in areas with wolves.

●

Wolf monitoring and expectations for stakeholders and public: Monitoring and research should
be based on restoration and management goals, use a variety of techniques, and be connected
to other elements of wolf management, including conflict minimization. While robust
monitoring is valuable at early stages of reintroduction, limitations to monitoring will increase
with wolf population growth, requiring transition to a population estimate approach. It is
important to consider effective messaging and coordination with stakeholders and the general
public when communicating monitoring objectives and data; lead with trust and share data on
an as-needed basis.

●

Social and/or economic dimensions of wolf management: Social and economic dimensions are
critical to understand, measure, and incorporate into decisions on wolf management.
Perceptions of wolves and perspectives on management vary among people, are generally
consistent within interest groups, and often reflect deeply held beliefs and values. There is high
potential for social controversy and conflict, particularly as related to expectations and
acceptance for use of non-lethal practices, lethal control, recreational harvest/regulated public
hunting, and wolf population numbers. Some research suggests that economic benefits can be
substantial and much larger than economic costs, however economic benefits and costs are not
distributed equally across stakeholders and the public. Consider the breadth of existing social
science research, economic indicators, and stakeholder and public feedback when making
management decisions, and incorporate new social and economic research into future
decisions. Education and outreach can also inform and be informed by social science. It is critical
to have trusted, responsive managers on the ground and consistency of management.

�Wolf population management
Conflict-centered management vs. objective-based management
Summary of TWG Feedback: Wolf management should focus on management of conflict, with
consideration of the social factors that accompany an impact-based management approach. Lessons
from other states with wolves suggest population management is not robustly correlated with conflict
minimization. Generally, the public has a high expectation that state wildlife agencies will address
wildlife related challenges.
●

●

●

Focus on conflict-centered management properly scaled for issues involving livestock, ungulates,
etc.
o Have a systematic and flexible plan to be able to support and respond proactively and
reactively to minimize conflict.
o Impact-based management alone will not necessarily satisfy the needs and interests of
those that are concerned about wolf populations on the landscape.
o Impact-based management may also not satisfy the interests and concerns of those that
want wolves on the landscape.
The link between wolf population management (i.e., developing population objectives and
managing towards those objectives) and conflict reduction is not necessarily robust on a
statewide basis.
o There may not necessarily be more depredations with higher statewide wolf
populations (at some level, there are more conflicts as the population increases but
these do not necessarily have a linear relationship).
o Wolf population size and frequency of depredations do not share a linear relationship at
a Statewide scale in the northern Rocky Mountain states and other states. Conflict
minimization (lethal and non-lethal) play a role in this pattern in other states.
o Depredations are more common in places with higher wolf density and livestock density
at the local scale.
Effective management of livestock, big game and other conflicts at a local scale are distinct as
management issues from population objectives and population management over larger scales.
That is to say that local, impact-based management (managing to resolve conflicts) is different
than statewide management for population objectives. Diverse stakeholders need to be
involved at both scales, i.e., in defining approaches to local conflict management and determine
population size management over larger scales.
A population objective is not required for diverse stakeholder involvement in statewide
population management. Consensus on whether a population objective is needed or what it
might be has not been achieved among public advisory councils in other states, and similarly the
TWG could not reach consensus on this. A variety of biological and social considerations affect
this issue.
If a population objective is considered in the future:
o Any population management objective should be based in biological and social science,
including an understanding of social carrying capacity determined over time.
o If a wolf population objective is established, it is difficult to manage to that objective
through conflict management alone.
o If using regulated hunting for population management toward a population objective,
efficacy of regulated hunting depends on when the objective is set (i.e., the population

�o

at that time), what it is set at, and what other management and allowance for lethal
take are in place. Insights from other states suggest that regulated hunting is likely more
effective to maintain or achieve that objective when the wolf population is smaller.
TWG members do not have agreement on whether a population objective should be
established. Some members expressed concern in wildlife managers' ability to maintain
adequate pace of response to conflict as wolf populations grow. Some members
suggested that proactive management - setting and managing towards local or
statewide population objectives - may help to mitigate potential management capacity
issues. Other members do not support the need for statewide population objectives.

Avoiding misinterpretation of maximum vs. minimum population metrics
Summary of TWG feedback: It is important to use clear and consistent messaging to reinforce the
purpose of minimum population counts/estimates, which are not intended as population objectives or
maximums and have been misinterpreted in other contexts.
Note: Please see TWG’s separate report on recommendations and rationale regarding minimum
population thresholds and metrics for State downlisting and delisting.
●

●
●

Minimum population counts for downlisting and delisting are not intended as and should not be
interpreted as population objectives nor maximums.
○ Be clear and consistent in the messaging of this; reinforce the message constantly at the
highest levels of leadership within the State.
Trust in the agency and its managers on the ground, along with its responsiveness and
engagement with the public, is important for the management of population size and other
topics.
Public and stakeholder focus on the minimum as a maximum is indicative of various interests or
concerns about wolves on the landscape, for example, concerns about livestock conflict,
ungulate impacts, ecological benefits, etc.

Zonal management
Summary of TWG Feedback: Initial and long-term management should be impact-based. Zonal
management of conflict could be a consideration for future management. Delineation of zones in the
future could be informed by experience and data gathered through impact- (and conflict) based
management, understanding of ecological and social suitability (inclusive of wildlife and agricultural
interests), and learnings from wolf dispersal and establishment on the ground.
●

Zonal management is a consideration for how to address social and ecological dynamics and
conflicts. Zonal management is the concept whereby different local areas are managed
differently with respect to the tradeoff between wolf conservation versus local wolf conflicts
while considering wolf population goals and trends at a larger scale. Conflicts refer to those with
livestock and big game, or other, less likely, interactions with humans, pets, or other species.
Management in some areas may be focused on wolf population conservation and growth while
management in other areas may have higher wolf mortality rates to proactively minimize
impacts on big game or livestock depredation, so long as overall wolf population size or growth
are adequate.

�Zonal management does not refer to geographic recovery area; the TWG has proposed
Statewide recovery thresholds for Colorado.
○ Zonal management does not refer specifically to management based on population
objective, but rather based upon ecological and social suitability and conflict.
Above minimum population thresholds, zonal management can be used with management
favoring different outcomes (e.g., wolves, agriculture) where social and ecological conditions
support them.
○ Consider the Colorado State University (CSU) and US Department of Agriculture Animal
and Plant Health Inspection Service- Wildlife Service (USDA-APHIS-WS) model for
habitat suitability/conflict to inform zonal management: this includes social and
ecological factors.
■
This model suggests the existence of ecological and social suitability in Colorado,
with low conflict, to support zonal management.
■
Truthing the model with data collected from wolf monitoring in Colorado will
help to validate it prior to establishing any zonal management in the state.
A consideration for timing of implementation of zonal management is that where wolves are
released is not necessarily where they will end up: this includes consideration that Proposition
114 requires release west of the Continental Divide but introduced wolves will almost certainly
move east of the Divide and naturally migrating wolves are already present east of the Divide.
Delineation of management zones is best informed with experience and data on wolf
establishment and distribution on the ground.
Delineation of wolf management units with lines on a map is complex, should be informed by
Colorado-specific data and goals, and should embed flexibility over time based on management
learning and experience. For example, in Montana, the decision to apply zonal management was
made with 15 years of data on wolves on the landscape.
Impact/conflict-based management can occur without zonal management; i.e., rather than
drawing lines on maps, manage based on impacts in areas that emerge from the experiences on
the ground. Impact/conflict-based management can also inform the development of zonal
management over time, such that zones are delineated and managed according to the
emergent patterns of impacts.

Wolf population self-regulation
Summary of TWG feedback: Intrinsic self-regulation of wolves is unlikely at a statewide scale; wolves
will likely be extrinsically regulated particularly by social carrying capacity. Wolf population selfregulation does not achieve the same goals as conflict management.
●
●
●
●

Wolves are territorial; intrinsic self-regulation occurs at a high population density: in
combination with extrinsic regulation (see below) this can also be referred to as ecological
carrying capacity.
Self-regulation may be possible at a smaller scale but is unlikely to be seen at a statewide scale;
population density necessary for statewide self-regulation is unlikely to be seen in Colorado.
Wolves will adjust to food supply (extrinsic regulation) below the level at which intrinsic
population control limits the population size or growth rate.
Wolf population self-regulation is not a substitute for conflict management. Managers will have
to address conflict management before a wolf population reaches a point where it is functioning
at ecological carrying capacity, or the combination of extrinsic and intrinsic self-regulation.

�Positive impacts and wolf management
Summary of TWG feedback: Positive and negative impacts can occur due to wolf presence; positive
impacts do not generally require hands-on management but can be communicated through education
and outreach and can inform management activities and funding opportunities.
●
●

●
●

Positive and negative impacts can occur due to wolf presence on the landscape; these can
include ecological, social and economic impacts as discussed in sections below.
Positive impacts can be communicated and supported through education, information, and
outreach. For example, managers could share distribution maps (general areas, not den
locations or other sensitive data) to support wolf tourism (viewing, howling). Consider both the
positive and negative impacts of increasing tourism.
Positive impacts generally do not require hands-on-wolf management. However, where positive
impacts exist, they could inform management; for example, if there are positive impacts in a
park, consider managing for them by creating a buffer for management around that area.
Some literature indicates that while the economic benefits of wolves can be many times higher
than the costs of management to prevent and resolve conflicts, the distribution of benefits do
not align with the distribution of costs. Positive impacts could inform funding and support for
wolf management.

Management of livestock conflict
Non-lethal livestock conflict minimization
Summary of TWG feedback: Adoption of proactive and reactive non-lethal conflict risk reduction
techniques by livestock producers in Colorado is important to the long-term success of the wolf
restoration and management program. The effectiveness of these tools is context-specific and not well
quantified.
●
●

●

●

●

Non-lethal conflict reduction techniques include those implemented prior to and to prevent
conflict as well as those implemented following depredation to prevent further conflict.
To be most effective at minimizing and preventing depredation events, non-lethal conflict
techniques should ideally be applied early and properly when wolves are in or anticipated in an
area. To accomplish this, advanced preparation and engagement among the agency, partners,
livestock producers, nonprofits, and others working on conflict minimization in Colorado is
strongly advised prior to and continuing through reintroduction.
Experiences with livestock producers in other states also suggests that incentivizing and allowing
creativity in conflict risk reduction approaches and working with producers is an effective
approach.
Context-specific considerations for effectiveness and feasibility of use of conflict risk reduction
techniques include livestock type, age, time of year, land size, other land uses, landscape
conditions, and local geospatial features, among other considerations that may impact livestock
operations and wolf predation behaviors.
Quantifying the effectiveness of various non-lethal tools is difficult and research in this area is in
development, suggesting effectiveness is highly context-specific and requires some trial.

●

Suggestions for dissemination of non-lethal tools include building upon and/or leveraging
relationships with members of the agricultural community, including through agency outreach
(CPW, USDA APHIS-WS, and/or Colorado Department of Agriculture), community collaboratives,
NGOs, stakeholder groups and livestock producer associations, rancher-to-rancher engagement
and training programs, academic programs such as Colorado State University Extension, and
conflict risk reduction cooperatives.
Providing funding support, either directly or through cost-share programs, may help to foster
adoption of techniques.

Post-depredation management of conflict wolves
Summary of TWG feedback: While wolf depredations on livestock in other states are uncommon and do
not represent a notable burden to the livestock industry as a whole, some wolves do cause significant
problems for some ranchers and some areas experience repeated and frequent wolf depredations on
livestock. Management of wolf-livestock conflicts following depredations should allow flexibility for
managers; non-lethal and lethal management techniques should be applied adaptively and are contextspecific. To be effective at reducing further depredation events, lethal and non-lethal responses for
resolving conflict should be applied quickly and properly. Relocation of depredating wolves has little
technical merit.
●
●

●

●

●

A guiding principle for management should be to allow wildlife managers flexibility, such as in
defining a problem and/or conflict wolf and/or chronic depredation.
Chronic depredation would consist of multiple depredations and could consider temporal and
spatial factors (e.g., from other states: two depredations in a calendar year, three within ninety
days, or four within a relative nine-month window from first depredation), as well as the phase
of recovery and management. Simplicity should be a guiding factor in this definition. A potential
definition for a conflict wolf would be a wolf that creates conflict, not exclusive to but including
depredation.
Management response may vary between one or multiple depredations, and depredation
response may not always be driven solely by depredation frequency. For example, lethal
removal might be an effective way to reduce future depredations after an initial depredation
event if the wolf population is large enough, and implementation of non-lethal deterrents may
be effective after multiple depredation events in a small pasture situation.
It can be difficult to determine which individual wolf or pack is depredating, and an alternative
could be to consider depredation by area, such as focusing on depredations affecting a producer
and/or community rather than on the individual wolves and/or packs. Knowledge of areas
where conflict is more likely to occur will increase over time, and adaptive responses can be
tailored based on this knowledge. Areas with higher wolf density and livestock density tend to
be those with higher conflict.
Efficacy of non-lethal techniques vary on a case-by-case basis, including factors such as if a
depredation has already occurred as well as spatial and temporal conditions for when and how
the depredation occurred.
○ While efficacy of non-lethal methods may decrease over time or after an initial
depredation, implementation of non-lethal methods and aversive conditioning postdepredation have had success to prevent further depredations and prevent use of lethal
management actions.
○ A specific example of an effective non-lethal technique is the removal of bone piles and
other attractants, ideally pre-depredation, or potentially post-depredation.

Some landscape conditions, independent of individual predator or pack reputation or
conflict minimization, may create conflict hotspots.
The effectiveness of translocation of conflict wolves may vary. Relocation of conflict
wolves has little technical merit and presents a social challenge in relocating a known
depredator elsewhere.
■
Those wolves might attempt to return back to their original location and/or
create problems for producers in other places.
■
Relocation takes significant time and resources.
■
If the purpose of relocation is to stop further depredations, it is important to
consider whether this accomplishes that purpose.
■
This practice has only been previously used if managers do not have flexibility
via regulation to use other conflict wolf management tools.

Lethal management of conflict wolves
Summary of TWG feedback: Lethal and non-lethal management are both critically important tools for
conflict minimization; lethal management will likely attract greater social attention. In evaluating the
management approach on a context-specific basis, consider the trade-offs among ability to target
depredating wolves, conflict minimization efficacy, cost, reproductive and recruitment success, wolf
population size and listing status, impacts to livestock producers, and social/stakeholder interests when
considering lethal take options, including incremental and whole pack removal.
●
●

●

Availability of both lethal and non-lethal management tools is important to support
management flexibility.
Lethal management of wolves will be accompanied by significant social attention in Colorado.
o Some social science research suggests Coloradans are least likely, compared to other
states in the region, to support lethal management and that non-lethal tools will need
to be an integral part of management.
o Wildlife damage management research has consistently shown the affected public
supports lethal management and the unaffected public generally does not support
lethal management regardless of species involved.
o Proper emphasis and exercise of non-lethal techniques, quality of investigations, agency
transparency and education and outreach about conflict management and conflict
wolves should be among factors considered prior to justifying lethal techniques to
respond to and prevent future depredations.
Targeted lethal control may decrease future depredations. There are tradeoffs between
incremental (individual) removal and whole pack removal:
o There have been both successes and failures with incremental removal.
o The more wolves that are removed, the higher the efficacy for reducing conflict and
reducing likelihood of an additional depredation; however, there is a tradeoff in terms
of wolf recruitment, and in some cases, social acceptability.
o Incremental removal of individuals responsible for the depredation may be more
socially acceptable. However, it is difficult to effectively target the individual
depredators (due to time, knowledge, and monitoring constraints); consider targeted
incremental removal in early phases when managers have the ability to target
depredating wolves.
o Wolf populations can sustain 25-30% annual mortality while maintaining a stable or
increasing population. This is well above the level of mortality that would be expected

●

due to lethal take for management of depredating wolves: however, it does not address
the specific ecological and social consequences of lethal removal when only a small
number of wolves or packs are present (i.e., early in reintroduction).
o Data do not suggest that depredation will increase due to lethal removal of individual
wolves from a pack.
o Lethal take of depredating wolves may increase effectiveness of non-lethal
management techniques by removing individuals with bolder behavior and conditioning
fear of humans in remaining pack members: however, the science is not robust on this
topic.
o Lethal removal is problematic if the individual depredators are also the breeding
individuals, which will affect recruitment. The probability of persistence and
reproduction decreases as more individual wolves are removed from a pack.
o If there is not reproduction, lack of pups can lead to pack dissolution.
o The larger a pack, there will be more resilience to a mortality event and the
higher likelihood that the pack will recruit pups the year following removal.
However, larger packs are also more likely to depredate again.
o Seasonality and whether the removed wolves are breeding individuals will also
affect pack persistence and reproduction.
Management options could consider the role of lethal control in areas of public land grazing vs.
areas of mixed public and private lands. This was a consideration for phased management in one
Northern Rockies state, where more liberal management was included in earlier phases for
areas of mixed private and public land, whereas management was liberalized in later phases for
public lands. However, differentiation raises challenges for consistency of management.
Alternatively, options could consider land use patterns rather than land ownership. There are
many areas where public and private lands are interspersed and not fenced; knowing precisely
whose land an action occurred on can be problematic. However, it may be possible to consider
management based on the general use patterns (agricultural, residential, recreational,
wilderness, etc.).
Public harvest (different than conflict management) has not directly led to a decrease in
depredation in areas of harvest in other states, but there are indirect impacts for wolves being
sensitized to and fearful of humans as a result of public harvest, which may in turn decrease
wolf interactions with and depredations of livestock.

Management of interactions with ungulates and other wildlife species
Considerations for ecological effects
Summary of TWG feedback: Ecological function is an important factor to consider but is difficult to
quantify and may be less relevant as a metric at the state scale.
●

Positive ecological effects from having wolves on the landscape can occur, however they are
difficult to quantify and document, require appropriate scale, and are also situation-specific.
Landscape level ecological effects are both difficult to quantify and to achieve.
o Ecological effectiveness is a vague concept and situation-specific; for example, positive
effects of a full complement of large carnivores in Yellowstone may not apply in other
areas.

11

�o

Ecological effectiveness and trophic cascades across a large area are not likely to occur
until there is a saturated wolf population. However, management to address social
carrying capacity and conflict in human-dominated landscapes will impact pack size and
distribution and will likely limit achievement of ecological carrying capacity.

Impacts of wolves to ungulates, big game, and big game hunting
Summary of TWG feedback: Although statewide impacts to ungulate populations and hunting
opportunities have not occurred in other states and are unlikely in Colorado, wolves can have local
impacts to ungulate recruitment due to predation of young ungulates. Wolves prefer elk and will also
prey on deer and other ungulates; moose may be targets of predation where they are abundant.
Reduction in big game hunting opportunities and targeted wolf control have sometimes occurred locally
in other states to address negative ecological or economic effects of reduced ungulate populations.
Ungulate populations are impacted by a complexity of interacting factors.
Predators like the gray wolf may select for prey compromised by infectious diseases, which could prove
useful in reducing infectious disease prevalence in ungulate populations, primarily when pathogens are
directly transmitted among hosts. The strength of a potential disease reduction depends on numerous
factors, including specific disease etiology, the strength of selection for infectious individuals, and
overall predation rates. It is unclear whether wolves will have a measurable effect on chronic wasting
disease (CWD) in Colorado, where environmental contamination is likely to be a primary transmission
route and where CWD is already well-established in mule deer, a species that wolves generally do not
select for in the presence of elk.
●

●

●

At a statewide level, wolves are unlikely to have a major impact on overall big game populations
or hunting opportunities in Colorado based on evidence from northern Rocky Mountain states.
Ungulate populations are impacted by a complexity of interacting factors.
Impacts of wolves to ungulates are a local rather than statewide issue; ungulate management in
response to gray wolf impacts should also be localized.
Wolf-prey selection demonstrates a strong preference for elk over deer, where elk are present.
The impact of predation is focused on recruitment because wolves tend to eat young elk; they
will prey on a variety of age classes of different ungulate species (including reproductive and
non-reproductive age): however, their preference is for young and old elk. This impact occurs in
combination with presence of other predators and ungulate habitat limitations. Wolf predation
occurs throughout the year, with some seasonal variability and peak kill rates in late winter.
In other states where wolves are present with other carnivores, reduction in big game hunting
opportunities (particularly cow hunting or through changes in license type) has sometimes
occurred to maintain ungulate population size. Declines in ungulate population size have
occurred when reductions in recruitment due to predation have occurred in combination with
cow hunting. Therefore, recent big game management in other states where wolves are present
has focused on reducing or eliminating cow hunting opportunities to avoid population declines.
In some states, under both federal and state management authority, wolf control may be
considered if it was determined that wolves were a contributing factor to negative performance
of big game populations.
o Wolf impacts to ungulate populations are localized, typically occur in the presence of
impacts from multiple large carnivores, and examples of impacts and subsequent
management of wolf impacts to big game are rare; some areas such as NW Montana
and the LoLo area of Idaho have been managed for wolf impacts to big game.

�Under federal management authority, it was only allowed for nonessential experimental
populations in States that had Service-approved wolf management plans (i.e., ID, MT,
WY), although when this might be considered changed slightly over time.
o Many state wolf management plans also consider wolf impacts to big game populations
and when wolf control may be considered to improve the performance of big game
populations. These considerations vary by state. In Montana, Idaho and Wyoming, there
are regulated hunting seasons. Both Washington and Oregon have very similar language
as to what is proposed for how wolves could be managed should there be demonstrated
effects on local ungulate populations.
In addition to considerations for infectious disease and CWD (discussed above), there are
considerations for potential wolf effects on ungulate population health and noncommunicable
disease. Gray wolves preferentially select for relatively weak prey, including old and diseased
(i.e., noncommunicable) prey, which may reduce disease prevalence such as arthritis.
Moose are generally not a significant portion of wolf diet; however, wolf predation of moose is
variable and the impacts to the moose population are localized, dependent in part on the size of
the moose population. Wolves are more likely to select moose where moose populations are
higher. In Yellowstone, moose are rare and moose predation is low. In locations where moose
populations are low, there is potential for relatively higher impacts from wolf predation, even if
wolf predation of moose is low.
o Moose are challenged by a variety of problems that overshadow wolf predation; these
include living on the southern end of their range, including habitat, parasites and ticks,
bear predation, and potential competition with elk on winter range; challenges are
driven by climate and heat stress at the southern end of their range and this can be
compounded by climate change. Moose populations in Colorado are doing well.

Interactions on other wildlife species, particularly other large predators and/or other
threatened and endangered species
Summary of TWG feedback: Wolves are important components of trophic networks where they are
present on the landscape and their presence may have interactions with other large carnivores. The
presence of wolves will not have an impact on populations of threatened and endangered species in
Colorado, specifically lynx and Gunnison sage grouse.
●
●
●
●
●
●

●

Various species benefit from carcasses of prey killed by wolves.
Abundance and distribution of carrion/carcasses in the winter may benefit wolverines.
Wolves will kill individual coyotes; Yellowstone data show that coyote populations survive but
may change their pack dynamics and behaviors.
Wolves, lions, and bears may interact and cause some limited mortality for each other.
Wolf kill rates may decrease in the presence of grizzly bears (not present in Colorado); grizzly
bears are dominant on wolf kill carcasses in summer and wolves will stick with carcasses thus
reducing kill rates.
The effects of wolves on lion populations are variable. Northern Yellowstone research did not
find a population effect of wolves on lions. Lions may move down in elevation in the absence of
wolves. Mountain lion kill rates may increase in presence of wolves because wolves are
dominant to lions on carcasses, and lions may increase their kill rates as a result.
Wolves will eat beavers; in the Great Lakes states, beaver can represent half of wolf diets and
30% of biomass consumed: however, there is generally not a population effect on beavers. Wolf
predation of beavers is potentially more opportunistic than bear predation of beavers.

There is no reason to believe that there will be a significant impact of wolves on lynx or the
Gunnison Sage-grouse and Greater Sage-grouse.

Management of conflict with humans and domestic pets
Summary of TWG feedback: Attacks by wolves on humans are exceedingly rare; education and outreach
for recreationists and other public lands users should include best practices and guidance, including how
to differentiate wolves and coyotes. Flexibility to address rare instances of wolf habituation in areas
dominated by humans is important.
Wolf attacks on pets are uncommon; education, outreach, and management should be used to
proactively prevent conflict. It is important that public messaging emphasizes the risks assumed when
domestic and hunting dogs are present in areas with wolves.
●
●
●

●
●
●

●

Strong public messaging should emphasize that dogs can be an attractant for wolves, and,
although rare, wolves will kill dogs. Recreationists and hunters should all be aware of this risk
when taking dogs into wolf country.
Hunters that use hunting hounds should be aware of wolf presence where they are hunting and
factor that into their decisions regarding whether to hunt with dogs in that area. Wolves do kill
hunting hounds, particularly those that hunt far away from people.
Livestock guardian dogs remain an important consideration for conflict minimization; livestock
producers with livestock guardian dogs should also be aware of the risk of wolves to dogs. The
use of larger livestock guardian dogs to protect against wolves can also have potential impacts
for domestic pets and hunting dogs, due to conflicts between the livestock guardian dogs and
pets/hunting dogs sharing the same landscape.
Consideration of recreationists’ experience and purpose on the landscape can help inform
education.
There can be issues with mistaken identity: dogs can be misidentified as wolves; recreationists
that are shooting coyotes could mistakenly shoot wolves.
Distinguish between tolerant and habituated wolves:
○ Tolerant wolves may walk through campsites or pass by people. Wolves that become
more tolerant of people are more susceptible to poaching and hunting.
○ Wolves may occasionally become habituated. For example, in Yellowstone National
Park, wolves may occasionally take human food or items from campsites.
○ Hazing is a key part of the toolkit for managing habituated wolves and is an effective
tool used on a case-by-case basis.
■
Effectiveness of hazing is increased when it is implemented early, before wolves
become more bold and habituated.
■
Hazing and aversive conditioning can also be challenging for a management
agency because of the need to catch the animals consistently in the act of the
behavior that you want to discourage.
■
Having hazing available to producers can support early intervention.
■
A phased approach to hazing and habituation could be considered based on
population status.
■
There have been two instances in Yellowstone of lethal take for aggressive and
habituated wolves.

State and federal law allow take of wolves that are threatening human safety.
Management of a wolf that kills a pet or hunting dog will depend on the context; it is
important for state agencies to have flexibility.
Flexibility to address other situations such as wolves denning in human-dominated areas
with various tools and on a case-by-case basis is recommended. It is difficult to
anticipate all scenarios for interactions with humans, recreationists, livestock, other
wildlife, etc.
Well-trained staff that are good at communicating and managing is important.

Wolf monitoring and expectations for stakeholders and public
Summary of TWG feedback: Monitoring and research should be based on restoration and management
goals, use a variety of techniques, and be connected to other elements of wolf management, including
conflict minimization. While robust monitoring is valuable at early stages of reintroduction, limitations
to monitoring will increase with wolf population growth, requiring transition to a population estimate
approach. It is important to consider effective messaging and coordination with stakeholders and the
general public when communicating monitoring objectives and data; lead with trust and share data on
an as-needed basis.

There is value in collaring every wolf that is reintroduced for monitoring and data collection
purposes and to learn from and improve upon for future releases; however, it is important to
educate the public and set expectations that not every wolf in Colorado will be collared as the
population grows. There is a risk that the public will incorrectly perceive that the agency is
failing in its monitoring efforts over time as fewer wolves are collared and monitored.
It is important to understand that collars tell managers where wolves have been but not where
they are present; monitoring cannot necessarily prevent conflict, but it can increase education
on wolf behaviors, patterns, and presence in an area. It can also help in educating people on
what to look for with respect to livestock conflict minimization.
○ Some non-lethal tools (i.e., radio-activated guard (RAG) boxes) rely on radio collars;
there may be interest in collaring for these purposes, aside from collaring for the state
monitoring program. RAG boxes can be used to scare wolves away over a short distance.
Ideally, they would be used to alert ranchers of wolf presence, particularly in areas of
prior depredation.
○ Immediately following a depredation event can also be an effective time to capture and
collar wolves.
○ Collar reliability and longevity varies, and GPS collars are less reliable than VHF collars. A
combination of collars can support an effective monitoring program. 1
Monitoring and research programs should be based on the wolf restoration and management
goals and objectives.
○ Colorado’s downlisting and delisting thresholds provide recovery goals to guide
monitoring program design.
○ Population growth rate is an important indicator for recovery goals. It can be informed
by abundance monitoring (e.g., minimum counts, population estimations, number of
packs), survival monitoring (adult and pup), recruitment (including reproduction and
survival, as well as immigration), and distribution (e.g., den locations).

See the November 2021 TWG Restoration Logistics Report, Pages 17-18, for additional discussion of collars.

�Survival monitoring is an indicator of performance rather than population size. Survival
is affected by conflict management, including lethal control.
Monitoring and research program design, costs, and effectiveness are interrelated with the
entirety of the wolf program, including conflict management.
○ It is essential for those conducting monitoring and those leading conflict management
and depredation investigations to communicate and effectively coordinate with each
other. Monitoring approaches and costs should evolve with the wolf population size,
from minimum counts and intensive ground (i.e., camera) and aerial monitoring toward
population estimates.
○ A wolf reintroduction and management plan should include a research effort to develop
a population estimate model beginning in the early stages of reintroduction. Such a
model will support a long-term monitoring program that does not rely on intensive
capture and collaring as the population size grows.
Monitoring and research are a year-round effort involving a variety of techniques to locate and
collar wolves.2
○ While a lot of monitoring work can be accomplished from the air and with aerial
captures, these techniques are more effective when there are already a lot of collars
deployed.
○ A fixed wing pilot with experience locating and tracking uncollared wolves from the air
can be an enormous asset in improving the success of helicopter capture efforts.
○ Foothold traps are an important tool for monitoring in other states. Injury rates for
foothold traps are low. Use of traps for all wildlife management in Colorado is extremely
limited per state Constitution; traps can be used for some conflict mitigation and
research purposes.
○ Significant groundwork and scouting are also needed to locate wolves, particularly in
early phases of restoration; groundwork increases absent the use of other techniques
listed above.
Adopt an approach to monitoring, information- and data-sharing that leads with trust.
○ Sharing data should be discretionary on an as-needed basis – for example, when
working with producers to minimize and manage conflict, or with research partners –
rather than a want-to-know basis.
○ Legal implications, including open records laws, should be considered prior to the
decision to share data. The statutory and regulatory basis for not sharing data should be
made clear to the public.
○ Information-sharing can be general in nature; it does not necessarily need to involve
sharing of specific telemetry data or other more sensitive information.
○ Sharing information with the ranching community provides transparency and factual
information, can build early trust, and can empower communities to understand the
data.
○ This must be balanced against protecting wolves from illegal take; however, there have
been positive experiences in other states in sharing monitoring data and locations.
○ Trust is reciprocal; there is risk in sharing information but agencies and ranchers must
be able to trust each other.
○ Monitoring activities can also include the public and private property owners.

�Social and/or economic dimensions wolf management
Summary of TWG feedback: Social and economic dimensions are critical to understand, measure, and
incorporate into decisions on wolf management. Perceptions of wolves and perspectives on
management vary among people, are generally consistent within interest groups, and often reflect
deeply held beliefs and values. There is high potential for social controversy and conflict, particularly as
related to expectations and acceptance for use of non-lethal practices, lethal control, recreational
harvest/regulated public hunting, and wolf population numbers. Some research suggests that economic
benefits can be substantial and much larger than economic costs, however economic benefits and costs
are not distributed equally across stakeholders and the public. Consider the breadth of existing social
science research, economic indicators, and stakeholder and public feedback when making management
decisions, and incorporate new social and economic research into future decisions. Education and
outreach can also inform and be informed by social science. It is critical to have trusted, responsive
managers on the ground and consistency of management.
●

Social and economic dimensions of wolf management consider a variety of stakeholders,
interests, and values, for example rural/agricultural and urban.
○ There is high potential for controversy and conflict among different perspectives with
respect to wolf restoration and management. There are deeply held, conflicting cultural
beliefs or values regarding wolves that are unlikely to change.
○ Social and economic dimensions affect all aspects of wolf management, including
restoration, conflict management, compensation and whether and how to approach
population management.
○ There is a broad spectrum of perspectives and research to consider specifically in
relation to social dimensions of wolf management, social acceptance, and recreational
harvest (or, regulated public hunting of wolves). Related to these issues are varying
perspectives on ethics and fair chase where regulated public hunting is allowed. These
topics will be controversial and contextual; demand, acceptance and/or opposition for
harvest will vary by cultures and geographies. Whether allowance or disallowance of
recreational harvest/regulated public hunting will change fundamental beliefs is unclear.
In addition to being informed by social considerations, allowance or disallowance of
regulated public hunting will also be informed by legal considerations including
interpretation of authorities relative to the definition of gray wolves in CRS 33-2-105.8
as being a nongame species.
○ There is also high potential for social controversy regarding whether and/or how to set
recovery criteria population goals, define self-sustaining populations, and manage
populations.
○ Failure to adequately consider different viewpoints can lead to politically driven swings
in management.
○ Wolf management and issues in other places, and especially in and around National
Parks, affect the national dialogue and state management; management around
National Parks involving more national interest groups and polarization can increase the
amount of social conflict.
○ Trust in messengers is important; different messengers are effective for different
audiences.

�Having responsive, trusted managers on the ground is important for navigating diverse
cultures and contexts with respect to wolves.
Existing and future social and economic science can inform management decisions.
○ Research should be balanced with experiential insights and learning from managers and
partners on the ground.
○ Social, economic and biological/ecological research each have the potential to be
interpreted to confirm and/or serve different perspectives and positions.
○ Stakeholder representation and leadership in development of the plans increases trust
and acceptance; general survey data are not enough.
○ Social/economic indicators (positive and negative) combined with on-the-ground
insights can inform future suitability assessments and zonal management by helping to
understand patterns of conflict, economic benefits, etc. (see discussion above).
○ A TWG member suggested engaging social scientists and economists to help expand on
insights synthesized in this report, including by summarizing public opinion surveys
conducted since the early 1990s, research insights from the 2020 Colorado election
results on Proposition 114, and other existing literature.
Social indicators to help inform management could include:
○ Consider the CSU and USDA-APHIS-WS model for habitat suitability/conflict (includes
ecological and social data (voting patterns)).
○ Consider ongoing CSU/CPW social science research in Colorado.
○ Behaviors and attitudes in response to wolf presence (for example, adoption of and
attitudes toward non-lethal conflict minimization practices and/or compensation, or
evidence of poaching or illegal take).
○ Perceptions and values. Consider examples of research from the Northern Rockies. For
example, in Montana, social science research has been conducted in 2012 and 2017 and
is scheduled to be repeated in 2022; it initially included surveys of big game license
holders, wolf license holders, landowners and wolf advocates, and then became a
general household survey. It included general wolf acceptance questions and questions
on tolerance of specific management actions (reactive to what was done); managers
noted that information collected from such surveys can be informative to management
but does not necessarily help with the issue of building trust.
Economic indicators to help inform management could include:
○ Impacts from any changes (if applicable) in ungulate harvest management correlating
with wolf restoration, with consideration of pre- and post-restoration license sales as
well as the relationship between hunting license sales and outfitting and ranching
economics.
○ Positive economic consequences (for example, for the outdoor industry, reduced vehicle
collisions, etc.).
○ Economic costs to producers of direct and indirect losses, non-lethal and lethal
management, and funding availability for management.
○ Economic costs to agencies (management, compensation, education/outreach,
additional staffing, resources, etc.).
○ If there is a net economic benefit, consider how, if possible, it can be quantified and
directed toward where the costs are incurred.
○ Economic assessments, particularly those that demonstrate significant positive benefits
of wolf restoration, could also be valuable to inform legislators/legislation and support
general assembly funding for wolf management.

�Introduction from the Stakeholder Advisory Group (SAG)
With the reintroduction of wolves, Colorado has an opportunity to restore its biodiversity while honoring the
livelihoods and traditions of our diverse communities. The Colorado Wolf Restoration and Management Plan
Stakeholder Advisory Group was convened to seek consensus among wolf advocates, ranchers, hunters,
outfitters, and conservationists who were tasked to explore the social, economic, and scientific aspects of wolf
reintroduction and management in an effort to benefit both wildlife and people.
This charge may have seemed impossible in a world of often polarized opinions. Over the course of 15 months of
relationship-building, difficult conversations, and information gathering, the SAG ultimately reached consensus
on a wide range of important issues that will guide CPW as wolves are returned to the state. Throughout, the
SAG fostered civil discussion and understanding across differences, often resulting in strong convergence even
on the most contentious issues.
In the SAG’s attempts to reach consensus, members recognized that there are areas where interests and beliefs
remained disparate and there was disagreement, as will be the case with the public. However, for Colorado’s
wolf program to be successful, there is a need to realize that there are real people affected by any decisions and
recognize people have more in common than apart. Everything will have unintended consequences that need to
be considered and can be lessened by having early conversations that lead to effective actions. Room needs to
be made for individual perspectives and locally-based solutions that help resolve challenges and reduce
divisions.
Across all topics, SAG members discussed the importance of achieving restoration of wolves with thriving
ungulate populations, rural communities, and agricultural economies. Discussions emphasized utilizing sciencebased, adaptive, and impact-based management at the local level that involves leaving wolves wherever they
are if they are not causing problems, minimizing conflict, and addressing issues on a case-by-case basis using a
variety of management tools. SAG members also underscored the critical need for long-term funding as well as
outreach and engagement to support wolf reintroduction and management.
Per the SAG’s charter, consensus recommendations in this report ‘will receive priority consideration by CPW.’
Accomplishments of the SAG include consensus on the following topics:
● A variety of restoration logistics recommendations provided by the Technical Working Group.
● Preventative, nonlethal wolf-livestock conflict minimization.
● Outcomes and principles for livestock compensation. The SAG also developed and voted on eight
compensation plan alternatives, reaching a high level of support for several of the alternatives regarding
compensation ratios and production losses.
● Impact-based management assumptions. The SAG also developed and reached consensus on a variety of
elements for a framework for impact-based management techniques allowed during various phases of
wolf management in Colorado.
● A statement on regulated public hunting of wolves including a recommendation that a decision on this
topic should not be made in the restoration and management plan to be finalized in 2023.
● Ungulate management recommendations regarding strategies to manage ungulate populations and
hunter opportunities in the context of wolf reintroduction and management.
● Funding recommendations to support and sustain a successful wolf restoration and management plan.
● Outreach and education recommendations to increase trust, transparency, and awareness as a
component of a successful restoration and management plan.

�About the Stakeholder Advisory Group (SAG)
This is a final summary and compilation of considerations and recommendations provided by the
Stakeholder Advisory Group (SAG) for the Colorado Wolf Restoration and Management Plan process.
Per the SAG’s charter, consensus recommendations in this report ‘will receive priority consideration
by CPW.’
The report synthesizes the SAG reports on restoration logistics; livestock compensation; nonlethal
conflict risk reduction; impact-based management; ungulate management and sportsperson
opportunities; regulated public hunting; education, engagement, and outreach; and funding. The fulllength reports for each topic are included as in chapters in this report.
The Colorado Wolf Restoration and Management Plan Stakeholder Advisory Group (SAG) offers a broad
range of perspectives and experience to inform the social implications of wolf restoration and
management strategies for the Colorado Wolf Restoration and Management Plan (hereafter, Plan). SAG
members were selected through an open application process by Colorado Parks and Wildlife (CPW) for
diversity in demographics, backgrounds, geographic regions, perspectives, and knowledge in order to
constitute a vibrant, diverse and inclusive stakeholder voice in the planning process reflective of the
issues and topics to be addressed in the wolf restoration and management plan. The SAG has a number
of wolf proponents, sportspersons, scientists, ranchers, outfitters, and many other stakeholders who
provide valuable and meaningful input to the agency’s planning process. The SAG was conscientiously
convened to represent the wide variety of perspectives that people in the state have on wolves;
however, the SAG was not intended to proportionately represent the general population, rather to
assure adequate representation from critical stakeholder groups. The SAG is comprised of 17 voting
members and 3 non-voting members. See Appendix A for the member list and Appendix B for SAG
biographies. It also includes representation from the Southern Ute Tribe; however, this representation is
not a substitute for government-to-government consultation.
The CPW-led planning process inclusive of the SAG was approved by the Parks and Wildlife Commission,
which is the sole body responsible for creating and approving the Plan as directed by the statute (CRS
33-2-105.8). Colorado Parks and Wildlife (CPW) is responsible for writing the Plan. The Parks and
Wildlife Commission (PWC) serves as the decision-making body responsible for approving the Plan. The
SAG serves in an advisory capacity to Colorado Parks and Wildlife, offering non-binding input into the
development of Plan content. The SAG is not a decision-making body and has no authority on wolf
management policy, research, or operations.
The SAG strives to make decisions based on the consensus of all voting members, where possible.
Where the SAG was able to achieve consensus, its input will receive priority consideration by CPW. Per
the SAG charter, consensus is defined as general agreement that is shared by all the people in a group; it
reflects a recommendation, option, or idea that all participants can support or abide by, or, at a
minimum, to which they do not object. In other words, consensus is a recommendation, option, or idea
that all can live with. See Appendix D for the SAG charter.
Where consensus did not exist, or where it existed and a roll call vote was requested, a roll call vote was
taken and the votes of individual voting members present for the vote were recorded along with a
summary of the rationale for supportive and dissenting views. Votes taken were recorded for each SAG

�member on a 1-5 consensus scale reflecting the following: 1) enthusiastically support; 2) support; 3) can
abide by or live with/does not object; 4) object; and 5) strongly object. CPW and the PWC are
encouraged to review and consider the details of each vote to understand nuances and insights in
situations where consensus was not reached, and to better understand why members objected,
supported, or could live with a particular idea.
SAG votes reflect level of support on an issue, not level of consensus; further, a majority or minority of
votes does not indicate passage or failure of a recommendation. Because the SAG is an appointed
stakeholder body rather than elected representatives, vote results are intended to help illustrate
individual, stakeholder views and are not indicative of the proportion of those opinions in Colorado’s
general population.
The SAG met once monthly in-person from June 2021 to August 2022, including a joint meeting with the
Technical Working Group (TWG) in December 2021 and virtually in January 2022. A total of 15 meetings
were held with the SAG, inclusive of the SAG-TWG joint meeting. Meetings of the SAG were open to inperson public observation (virtual in the case of the January meeting) and each offered a public
comment period. Meeting summaries were developed and published for each meeting. See Appendix C:
Stakeholder Advisory Group Meeting Dates and Locations for a list of meeting dates and locations.

Report on Wolf Restoration Logistics Recommendations
November 2021
This report summarizes Wolf Restoration &amp; Management Plan Stakeholder Advisory Group (SAG)
feedback regarding wolf restoration logistics. SAG feedback below is made in reference to the Technical
Working Group’s (TWG) report and recommendations on restoration logistics, and particularly the
‘Summary of TWG feedback’ sections of that report.
The summaries of the SAG’s August 2021, September 2021, and October 2021 meetings may also be
referenced for further detail of SAG member perspectives, questions and suggestions to the TWG
regarding clarification of the language and rationale of its report.
The SAG voting members have consensus in support of, and/or without objections to, the TWG’s
recommendations on the following:
Capture considerations:
● Donor populations
● Capture methods at source
● Age ratios
● Color ratios
● Sex ratios
● Genetic considerations
● Animal reputation
● Disease issues at source sites
● What to do with injured animals at source site
● Transportation method from source to Colorado
Animal handling considerations:
● What to feed during period of captivity, with the recommendation that native ungulate meat
should be preferred over carnivore logs.
● Where and how to hold animals prior to shipping and in Colorado
● Immobilization drugs to be used, with the recommendation that should a better, reversible drug
other than Telazol become available, it should be considered.
● Collars/marks on animals initially reintroduced into the state
● Samples collected from animals
● Veterinarian care in captivity
● Disease testing and vaccine treatment
Reintroduction considerations:
● Reintroduction technique (hard vs. soft release)
● Time of year

�The voting SAG members also discussed the TWG’s recommendations on the following reintroduction
considerations, and provided the following feedback:
●

Considerations for where wolves could be released. SAG members recommended that the
following factors also be considered, in addition to those discussed by the TWG: recreation in
various forms and contexts; finer detailed spatial sensitivity to local livestock operations and
potential acute social conflicts; need for direct engagement with immediately affected
communities; and the Brunot Agreement lands (i.e., consideration of management and Tribal
consultation needs; not, however, a recommendation to apply a spatial buffer to these lands; a
spatial buffer to sovereign Tribal lands is discussed in the TWG report and was suggested by SAG
members). It was also suggested that considerations for release sites include deer or elk
population Data Analysis Unit (DAU) trends and whether they are below or above objective, as
well as impacts on populations of other wildlife species of concern, beyond deer and elk, such as
moose, bighorn sheep, lynx and sage grouse. There was not consensus (i.e., full support and/or
no objection) for these recommendations; there was a range of support for the TWG
recommendations with the above additions, along with various concerns and two formal
objections that primarily addressed the process, timing, and/or implications of voting on this
specific topic during the SAG October 2021 meeting. SAG members emphasized that their
support for the considerations for where wolves could be released does not automatically imply
support for specific release locations. There were also concerns that a 75 mile buffer from state
and Tribal borders would overly constrain release locations that might otherwise be ecologically
and/or socially suitable.

●

Number of release sites (and release areas). SAG members did not vote on this topic. They
discussed arguments for a smaller number of release sites including better ability to manage,
concentrate resources, and minimize widespread conflict or social tension. Arguments for a
greater number of release sites included maintaining the ability to be flexible in reintroduction;
distributing reintroduction over a greater area rather than targeting a smaller number of
communities; and the possibility that using multiple areas might better align with the intent of
those who voted in support of wolf restoration. Comments cautioned against overly constraining
locations and sites.

●

Pace of wolf reintroduction and when to stop and/or pause reintroduction. SAG members did not
vote on these topics. They suggested the importance of adaptive management to assess both
the success of wolves and additional factors, including conflict minimization, ungulate
population trends, and social attitudes. Arguments for a slow pace included listening to requests
from the Western Slope to reintroduce wolves cautiously and slowly; to account for the presence
of naturally migrating wolves in Colorado; and to ensure that staffing, financial capacity and
ability to respond to conflict is not overwhelmed. Arguments for a medium or fast release pace
included ensuring a critical mass of wolves; accounting for potential illegal mortality as well as
other challenges to survival; minimizing genetic bottlenecks; avoiding loss of investment due to
any of these factors; and consideration of when lethal management tools could become
available as related to pace of introduction and the presence vs. rarity of wolves on the
landscape; it was suggested that these arguments are similar to those for wolf reintroduction, in
general. There was concern as to whether a ‘medium’ pace is a foregone conclusion because it
is defined as being between slow and fast paces.

Recommendations on Preventative, Nonlethal
Wolf-Livestock Conflict Minimization
March 2022
This report summarizes consensus recommendations of the voting members of the Colorado Wolf Restoration
and Management Plan Stakeholder Advisory Group (SAG) regarding preventative, nonlethal wolf-livestock
conflict minimization.

Conflict minimization program principles: Overview
●
●
●
●
●
●
●
●
●
●
●

Conflict minimization should be encouraged and explored as the first line of defense.
Support both preventative and post-depredation non-lethal practice implementation; emphasize and
implement proactive actions where possible and reactive actions as needed.
Provide financial, technical, and operational assistance to promote and implement conflict minimization
and risk reduction practices.
Apply and update, as relevant, regulations to support non-lethal conflict minimization practices.
Emphasize context specificity.
Recognize that not all efforts will prevent loss, while encouraging and supporting implementation and
innovation.
Emphasize producer education and outreach, leveraging experiences and lessons of other producers.
Provide sufficient agency capacity and funding for implementation.
As necessary based on resources, prioritize support for those that have experienced losses or are likely
to in the near future.
Use public-private partnerships to support CPW in funding, education, and implementation for conflict
minimization.
Adapt the conflict minimization program over time as needed.

Funding &amp; capacity
●

The conflict minimization program must be robustly and consistently funded for success.
o Establish and maintain separate funding sources for conflict minimization and compensation,
while providing for adaptability of the program over time to assess and address needs for each.
o Recognize that long-term funding will be necessary and while there are many potential
opportunities, funding sources can be complex and challenging to secure, with competition for a
variety of priorities.
o Funding for each source will ideally be appropriated from taxpayer money (state and/or federal)
and/or through multi-year public funds or grants (such as Great Outdoors Colorado (GOCO)
and/or federal programs), as well as other sources such as NGOs and private organizations.
▪ Sources should be additive to existing funding streams, provide longevity, and be
insulated from political debates.
o Establish a competitive grant or review program to review conflict minimization project
proposals.

�o

Enable additional sources (NGOs, private organizations, etc.) to contribute to funding for conflict
minimization.
▪ Establish a conflict minimization fund and solicit or encourage external funding
contributions early and/or prior to reintroduction while interest is high, so that it is
available when needed in both the short- and long-term.
▪ External organization funding should support projects and materials; state and federal
funding should be used to fund agency staff positions, capacity and services.
▪ Match funding mechanisms can be encouraged but should not be required; match could
help to increase competitiveness but a requirement should not stand in the way of good
projects.
▪ Flexibility for external funding contributions is important.

●

CPW capacity should include both depth and breadth of expertise on wolf and large carnivore conflict
minimization and management.
o Provide a wolf specialist(s) that offers coordination, leadership, consistency and emergency
response across the state. The specialist should also broadly understand carnivore conflict
minimization. CPW should fund this capacity.
o Require training for all District Wildlife Managers (DWMs) to create a breadth of experience and
insight for all carnivore damage and conflict minimization (bear, lion, wolf).

●

The economics of conflict minimization are a critical consideration for conflict minimization funding,
implementation, and management, and will be context-specific.
o Economics and efficacy of tools should be considered to inform:
▪ Funding needs and sources for the program.
▪ Management approaches that consider feasibility of conflict prevention.
o Economic considerations should be included in training for producers. Community-specific
training and insights of resource economists and those with practical experience over time will
be important.
o The specific tools needed, and costs (material and labor) of implementation will vary by
situation.
o Conflict minimization plans ideally should holistically consider not only wolves, but the
economics and resiliency of the ranch.

Delivery and implementation of conflict minimization tools
●

Incorporate producer perspectives and concerns in design and implementation of a program.
o Producers want to be proactive and preventative in protecting their livestock.
o Conflict minimization can feel overwhelming to producers. Concerns include but are not limited
to:
▪ Capacity
▪ Cost (to individuals and for the program as a whole)
▪ Uncertainty over effectiveness of practices for specific circumstances
▪ Interaction with other contracts, leases, and conservation strategies/requirements
▪ Guard dogs and liability
o There is a particular need to provide early support to producers in initial wolf release areas.

●

Success of conflict minimization depends on providing not just the tools and materials, but also
support to producers through technical knowledge, training, funding, labor and capacity to effectively
implement them.

o

There are details about the implementation for each tool that matter for success. It is important
to have the support and insight of people who have experience and knowledge on how to
implement and use these tools effectively.
Successful use of some tools and materials requires knowledge of both how and when to deploy
them and also how and when to remove them. For example, fladry has a limited period of
efficacy and should be lent out and reclaimed for use by multiple producers.
The costs and labor requirements of specific tools should be considered when anticipating the
level of financial and capacity support that will be needed for conflict minimization.

●

Outreach and training should occur proactively and continuously, and should provide practical insights
from producers.
o Training and shared learning should occur proactively and in an ongoing manner.
o Training and messaging should be improved and adapted over time based on initial learnings
and experiences.
o Training should include producer-to-producer insights from those with on-the-ground
experience.
o Examples should include realistic, authentic perspectives on conflict minimization, including
when it has and has not worked. Examples should include success stories as well as challenges
beyond a limited set of case studies.
o Training should include economic considerations (material and labor costs).
o Customize training and outreach with personal and local/community scale approaches.
o Include field demonstrations as part of training in order to provide hands-on, experiential
learning about conflict minimization tools.

●

A community level approach can foster broader implementation of conflict minimization.
o Some conflict minimization practices are more effective at a community level, and community
wide implementation can help to mitigate displacement of impacts among neighboring
producers.
o Under a community level approach, there are a variety of potential partners with community
connections that can help to develop a proactive effort.
o There are existing community cooperatives and structures used by producers to fund and
support conflict minimization, and there are also other kinds of community cooperatives (e.g.,
conservation districts, watershed groups, etc.) that could provide a basis and structure for
collaboration.

●

Producers have different relationships with different agencies and organizations; leverage these
relationships for success and do not rely on a single messenger.
o Consider the role of and potential for resources to support U.S. Department of Agriculture
Animal and Plant Health Inspection Service - Wildlife Services (USDA APHIS-WS), Colorado
Department of Agriculture (CDA), Colorado State University (CSU) Extension and other
organizations in conflict minimization.
o Consider the role of both wildlife and agricultural expertise.
o A diversity of expertise and public and private sector organizational representation can be
beneficial in providing information and training.

●

There is a need for better understanding of how implementation of conflict minimization tools and
strategies on federal lands interacts with federal land management expectations, policies, permit
requirements and allowances.
o There may be opportunities for policy level state or regional discussion on these issues;
however, decisions are often specific to allotment conditions and modifying permits is difficult.

�About the Stakeholder Advisory Group
The Colorado Wolf Restoration and Management Plan Stakeholder Advisory Group (SAG) offers a broad
range of perspectives and experience to inform the social implications of wolf restoration and
management strategies for the Colorado Wolf Restoration and Management Plan. SAG members were
selected by Colorado Parks and Wildlife (CPW) for diversity in demographics, backgrounds, geographic
regions, perspectives, and knowledge in order to constitute a vibrant, diverse and inclusive stakeholder
voice in the planning process. The SAG is comprised of 17 voting members and 3 non-voting members.
CPW is responsible for writing the Wolf Restoration and Management Plan. The Parks and Wildlife
Commission (PWC) serves as the decision-making body responsible for approving the Wolf Restoration
and Management Plan. The SAG serves in an advisory capacity to Colorado Parks and Wildlife, offering
non-binding input into the development of plan content. The SAG is not a decision-making body and has
no authority on wolf management policy, research or operations.
The SAG strives to make decisions based on the consensus of all voting members, where possible.
Where the SAG is able to achieve consensus, its input will receive priority consideration by CPW. Per the
SAG charter, consensus is defined as general agreement that is shared by all the people in a group; it
reflects a recommendation, option or idea that all participants can support or abide by, or, at a
minimum, to which they do not object. In other words, consensus is a recommendation, option or idea
that all can live with. Where consensus does not exist, a vote will be taken and the votes of individual
members will be recorded along with a summary of the rationale for supportive and dissenting views.

�CPW WOLF RESTORATION &amp; MANAGEMENT PLAN STAKEHOLDER ADVISORY GROUP
COMMENTS ON PROPOSED WOLF HAZING REGULATION
December 22, 2021
SUBMITTED to THE PARKS AND WILDLIFE COMMISSION

Regulation Issue Paper:
https://cpw.state.co.us/Documents/Commission/2021/November/Item.19-W-10-IssueHazing.pdf
Key Concepts:
•
•

•

•

•

•
•

We support hazing of wolves as tool to reduce the potential for livestock depredation by
wolves, and we also support the prohibition on causing injury to wolves.
The regulation should make it clear that allowable activities are intended to reduce the
immediate threat to livestock. Pursuing wolves for extended time or distance defeats the
purpose of training wolves to avoid livestock, greatly increases the likelihood of harm to
the wolves, and must be prohibited.
Inadvertent injury or death caused by hazing could occur. The draft regulation considers
such harm as a violation. Some SAG members feel that such unintended harm should
not be considered a violation of the law; others feel that is should be a violation.
Livestock guardian animals can potentially injure or kill wolves. The Mexican gray wolf
program has language that addresses such circumstances and does not hold the guard
animal’s owner liable for an illegal take under those circumstances. The wording from
the Mexican gray wolf 10(j) rule is as follows: "Take of Mexican wolves by livestock
guarding dogs, when used in the traditional manner to protect livestock on Federal and
non-Federal lands, is allowed."
Most of the techniques permitted by the proposed regulation would clearly not cause
injury to wolves. All permitted hazing techniques should be evaluated for their potential
to cause injury to wolves with that information provided to the Commission for its
consideration. The Commission should be provided with any information or evaluation of
the potential for injury specifically from rubber bullets and rubber buckshot. Some SAG
members feel that methods that have a high potential for injury should not be permitted.
Aircraft use by the public should not be permitted for wolf hazing, but it may be a tool for
agency use in limited circumstances.
Horses should be included in the same category as vehicles (e.g., ATVs) to ensure that
hazing by range riders or other employees or agents is a legal method. As
Commissioner May noted at the November 18 Commission meeting, range riders
moving wolves away from livestock could be viewed as a form of hazing and if so,
should be explicitly included as an allowable technique; we suggest doing so by adding
“horses” to the same section as ATVs and vehicles.

Our suggested specific modifications to the proposed regulation include:

•

Adding “employees and agents” to “livestock owners” (Section 1) to make it clear they
are authorized to use the hazing techniques.
Adding “livestock guard animals” (Section 1) so that hazing to prevent injury to those
animals by hazing wolves is permissible.
Adding “including horses” after “ATVs and vehicles...” in Section 1.a.iv so that horseback
hazing is specifically permitted.
Inserting “...but not limited to...” after “such as” in Section 1.a.v to clarify that scare
techniques other than those listed are permitted.

�Outcomes, Principles and Recommendations Across All Alternatives
Desired outcomes of a livestock compensation plan
● Livestock owners are fairly compensated for losses and are not financially harmed.
● Conflicts are minimized.
● Wolves are restored.
● Trust and support are built across communities.
Principles of a livestock compensation plan
● Build trust, transparency, relationships, and good will with agricultural communities.
● Be consistent, equitable, fair, and robust.
● Value both fair compensation and personal responsibility.
● Be simple and straightforward.
● Provide opportunity for choice and options.
● Recognize different kinds of grazing contexts.
● Promote conflict minimization.
● Support with sustainable funding and capacity.
● Use State-Federal partnerships and public-private partnerships where appropriate for
implementation and funding.
● Emphasize education and outreach.
● Maintain fiscal responsibility.
Education and outreach
● Education and outreach are important components of the delivery and communication of a
livestock compensation program.
● Incorporate education and outreach for producers to ensure awareness and understanding of
the program and administrative processes.
● Incorporate education and information for the public.
Conflict minimization &amp; risk reduction program elements
SAG members recommend that any compensation plan be implemented in conjunction with a robust
conflict minimization program. Some compensation plan alternatives considered by the SAG directly
incentivize producers’ use of nonlethal conflict risk reduction techniques. The SAG recommends a
conflict risk reduction program with the following elements:
● Provide financial, technical, and operational assistance to promote and implement conflict
minimization and risk reduction practices.
● Apply and update, as relevant, regulations to support nonlethal conflict minimization practices.
● Support both preventative and post-depredation nonlethal practice implementation; emphasize
and implement proactive actions where possible and reactive actions as needed.
● Emphasize context specificity.
● Recognize that not all efforts will prevent loss, while encouraging and supporting
implementation and innovation.
● Emphasize producer education and outreach, leveraging experiences and lessons of other
producers.
● Provide sufficient agency capacity and funding for implementation.
● As necessary based on resources, prioritize support for those that have experienced losses or
are likely to in the near future.
● Use public-private partnerships to support CPW in funding, education, and implementation.

�SAG Vote Results on Livestock Compensation Plan Alternatives
SAG members developed and discussed eight compensation plan alternatives. Descriptions of and SAG
feedback for each alternative are provided in the subsequent sections of this report. SAG members
voted at their January 2022 meeting to indicate their preferred alternative as well as their level of
support or objection on a consensus scale defined in the SAG charter. The votes of individual members
are included in the table on the next page.
In summary:
● There was not consensus support for any one alternative (i.e., all members in support of or
without objection to an alternative).
● SAG-developed alternatives for ex post (after the fact) compensation had the greatest number
of voting SAG members supporting or not objecting:
o Alternative 4: Itemization for compensation of production losses and missing livestock
(15/17 SAG members supporting/not objecting)
o Alternative 3: Simple compensation ratio for missing livestock (14/17 SAG members
supporting/not objecting)
o Alternative 5: Producer chooses between simple ratio (Alternative 3) or itemization
(Alternative 4) (13/17 members supporting/not objecting)
▪ Alternative 5 had the highest number of SAG members selecting it as their
preferred alternative (11/17 members preferred it over all other options; no
other option was preferred by more than 2 SAG members).
● SAG-developed alternatives for ex ante or outcome-based compensation had a majority of
voting SAG members supporting or not objecting:
o Alternative 6: Outcome-based compensation in addition to ex post Alternative 1 (11/17
SAG members supporting/not objecting)
o Alternative 7a: Outcome-based compensation parallel to ex post Alternatives 1 and 2
(9/17 SAG members supporting/not objecting)
o Alternative 7b: Outcome-based compensation parallel to ex post alternatives 3, 4, and 5
(9/17 SAG members supporting/not objecting)
● Existing ex post compensation alternatives had the lowest number of voting SAG members
supporting or not objecting:
o Alternative 1: Current CPW game damage process (8/17 SAG members supporting/not
objecting)
o Alternative 2: 2004 Wolf Working Group recommendations (7/17 SAG members
supporting/not objecting)

�Summary of SAG Discussion of Livestock Compensation Plan Alternatives
An overview of each alternative is provided below, followed by a summary of SAG feedback (rationale for
support, opposition, and additional considerations).1 Appendix A includes a more detailed description of each
alternative, inclusive of a description of the method of confirmation of depredation events; compensation and
eligibility for missing losses, indirect/production losses, ex ante compensation; and additional considerations.
Each alternative assumes the SAG-developed desired outcomes, principles, and conflict minimization and
education elements described above. In addition, the alternatives assume the following regarding program
administration and funding:
● The livestock compensation program is administered by CPW’s game damage program.
● Funding is through appropriations as enumerated in 33-2-105.8 C.R.S.
● Colorado Department of Agriculture has exclusive jurisdiction over depredating animals per 35-40-101
C.R.S.
● Administration and funding for ex ante/outcome-based alternatives 6, 7a, and 7b are to be determined.
● The livestock compensation program should be periodically evaluated and updated if needed (specific
recommendations for evaluation of certain alternatives are also offered in the detailed appendix).

Cross-cutting discussion themes
The following cross-cutting themes emerged during SAG member discussions of the alternatives (these themes
were recurrent, although not necessarily reflective of full consensus):
● Emphasis on desired outcomes and principles (e.g., fairness and no financial harm, nonlethal conflict
minimization, wolf restoration, trust and relationships, simplicity, choice, personal responsibility,
funding and fiscal responsibility, etc.; see page 2).
● Importance and interpretation of existing statute.
● Emphasis on basing compensation on best available science.
● Need for a robust conflict minimization program along with a compensation plan.
● Recognition of different values and perspectives regarding grazing, wildlife and public lands.
● Interest in compromise and collaboration across different perspectives.
● Concern regarding the impact of a compensation plan (whether perceived as too generous or too
conservative) on producer tolerance and/or public trust.
● Recognition of the range of economic losses caused by wolves to producers.
● Recognition of the role of working lands in supporting habitat and biodiversity.
● Concern regarding unduly blaming wolves for livestock losses and/or creating perverse incentives;
concern with lack of discussion of positive impacts of wolves.
● Recognition that details of specific alternatives will need to be further developed.
● Recommendation for periodic evaluation of any compensation plan.
● Interest in further consideration of outcome-based compensation options in the future.
● Interest in harmonization of compensation programs for different predators.
● Likely need to develop new intergovernmental agreements or memoranda of understanding with Tribes
to address sovereignty and jurisdiction-related issues such as participation in the State’s compensation
program and Tribal leadership and/or partnership in investigations of losses on Tribal lands.

SAG meeting summaries from October 2021 through January 2022 may also be referenced for additional discussion of
livestock compensation plan elements and alternatives. SAG discussions were also informed by feedback of the Technical
Working Group (TWG) to Colorado Parks and Wildlife regarding the technical merit of potential compensation plan
elements; see separate TWG report.

�Alternative 1: Current CPW game damage program
Overview
CPW’s current game damage program used for big game, including carnivores such as black bear and mountain
lion, provides 100% Fair Market Value (FMV) for confirmation under a preponderance of evidence standard.
SAG feedback (individual comments, not necessarily reflecting consensus):
Rationale for support for Alternative 1
● Consistency with the existing program is fair and easily administered.
● Support for a program that compensates for verified death and injury and not additional losses and/or
unverified losses.
● Wolves should be treated similarly to bears and mountain lions regarding compensation programs.
Compensation for unverified losses and/or other losses (above that provided in Alternative 1 or 2) may
create conditions where wolves receive undue blame for losses.
Rationale for opposition to Alternative 1
● Alternatives 1 and 2 do not recognize the real economic challenges faced by the agricultural community
and do not account for all losses that wolves have been documented to cause, such as missing livestock
and production losses. Some suggest that the law requires that these other losses must be covered.
● This alternative does not support outcomes of building trust and keeping livestock producers from
being financially harmed. Concern that a compensation plan that is too conservative will impact social
tolerance of wolves by producers.
Additional considerations for Alternative 1
● CPW’s existing game damage program could be a baseline for compensation, and the other alternatives
could be additions to gain social support from the agricultural community.
● Consider the importance and interpretation of existing statute in selecting a compensation program for
wolf depredation.
● Regardless of the original intent of the law or the existing program, recommendations developed
through the wolf management and planning process may help establish new precedents for livestock
compensation due to wolves.
● There is interest in receiving an official attorney general’s office opinion about the interpretation of 332-105.8 with regards to the State needing to “pay fair compensation to owners of livestock for any
losses of livestock caused by gray wolves."

Alternative 2: 2004 Wolf Working Group recommendations
Overview
The 2004 Colorado Wolf Management Working Group developed recommendations to compensate for
confirmed losses due to wolves at 100% FMV and at 50% FMV for probable losses.
SAG Feedback (individual comments, not necessarily reflecting consensus):
Rationale for support for Alternative 2
● Support for the concept of compensating probable losses in addition to confirmed losses.
● Support for a program that compensates for verified death and injury and not additional losses and/or
unverified losses, generally consistent with the compensation program for bear and mountain lions.

Wolf Plan Appendix C-24

24 of 107

�Compensation for unverified losses and/or other losses (above that provided in Alternative 1 or 2) may
create conditions where wolves receive undue blame for losses.
Rationale for opposition to Alternative 2
● Alternative 2 cannot be harmonized with Colorado’s existing game damage program because it
proposes a different standard for verification.
● While compensating for probable losses due to wolves, this alternative does not fairly compensate
producers for all losses, such as missing livestock and production losses, due to wolves.
● Concern that a compensation plan that is too conservative will impact social tolerance of wolves by
producers.
Additional considerations for Alternative 2
● Alternative 2 requires definitions and standards for verification for 'confirmed' and 'probable’ losses.
There are questions as to whether probable losses are already effectively covered within the existing
preponderance of evidence standard.

Proposed new confirmation standard for Alternatives 3, 4, and 5
Overview
Alternatives 3, 4 and 5 propose a new standard for the confirmation or verification of depredation events.
Specifically, the proposal is for 100% FMV for a depredation event (death or injury) for livestock (including guard
and herding animals) that the investigating officer reasonably determines is the result of a wolf depredation,
resolving any unknowns in the producer’s favor.
SAG feedback on the proposed alternative confirmation (individual comments, not necessarily reflecting
consensus):
Rationale for support for new confirmation standard
● The new standard was proposed by some SAG members based on producers’ input to them that
proving loss and entitlement for compensation for disturbed carcasses and missing animals is
impossible under a preponderance of evidence standard because disturbed, scavenged, or lost animals
cannot fulfill the burden of proof required of producers.
● The alternative standard was suggested to mitigate the burden of proof, avoid penalizing producers,
and resolve unknowns in their favor regarding disturbed/scavenged carcasses and missing animals.
● The new standard was also suggested to keep the process simple for CPW, to maintain positive
relationships between CPW and producers, and to enhance social acceptance of predators on the
landscape.
● The new standard would allow investigators flexibility to address varying scenarios of depredation
investigation and confirmation, offering a more practical approach to allow investigative officers to
make a reasonable determination based on their training and experience, including about disturbed
carcasses or missing animals.
Rationale for opposition to a new confirmation standard
● Opposition to compensation of full market value (or greater, in the case of a compensation ratio) on less
than a preponderance of evidence standard (which requires greater than 50% certainty).
● The new standard may create conditions where wolves receive undue blame for losses.
● The new standard would be inconsistent with the confirmation standard for bears and lions and may
impact the ability for compensation programs for wolves and other depredators to be harmonized in the
future.

Wolf Plan Appendix C-25

25 of 107

�Additional considerations regarding an alternative standard
● A new standard for determining wolf depredation requires additional legal scrutiny and potential
statutory change independent of a compensation plan.
● The new standard could be considered in the specific circumstance that CPW or APHIS-WS are not able
to respond to a claim in a timely manner.

Alternative 3: Simple compensation ratio for missing livestock
Overview
SAG members developed an alternative to compensate for depredations (death and injury) at 100% FMV
confirmed according to the proposed new standard above and to compensate for missing livestock (sheep,
calves and yearlings) up to a capped compensation ratio. Under the alternative, there must be a depredation
event due to gray wolves to claim missing livestock, and the number claimed cannot exceed actual documented
livestock loss. A two-tiered approach would provide a higher ratio for producers that employ nonlethal conflict
mitigation measures. Compensation for confirmed depredation of livestock (including guard and herding
animals) is for any livestock; the compensation ratio for missing animals is only for sheep, calves, and yearlings.
SAG feedback (individual comments, not necessarily reflecting consensus):
Rationale for support for Alternative 3
● Support for compensating for losses that wolves have been documented to cause, including missing
livestock.
● Support for a compensation ratio that could account for some additional production losses.
● Support for a simple option for compensation without being overly burdensome to agency capacity or
producers.
● Support for two tiers of a compensation ratio to incentivize the use of nonlethal conflict minimization
tools.
● Supports outcomes of building trust with the livestock community and keeping livestock producers from
being financially harmed.
● Support that the approach compensates for actual losses to the producer because claims are limited to
actual documented missing livestock.
Rationale for opposition to Alternative 3
● A ratio may be too generous; some losses are the cost of doing business.
● The alternative may result in compensation for losses that are not due to wolves and may cause wolves
to receive undue blame for missing livestock.
● A compensation ratio will create perverse incentives such that sick or injured livestock may be allowed
to be taken by large game predators in order to claim a missing livestock compensation ratio; this in
turn may disincentivize nonlethal mitigation of conflict and does not achieve desired outcomes.
● Producers should be responsible for verifying the location of livestock to avoid and confirm all losses.
● Nonlethal conflict minimization and mitigation tools are not adequately valued in this alternative as
they are not required to receive the lower ratio.
● Compensation for loss on public lands should consider that public lands grazing lease costs are low, with
impacts to the environment.
● Does not adequately compensate for production losses.

● The rates originally proposed by SAG members were a ratio of 5 for sheep and calves (2.5 for yearlings),
increased to a ratio of 7 for sheep and calves (3.5 for yearlings) if the producer employs nonlethal
conflict mitigation measures. These rates were proposed based on a literature review specific to
"missing" animals (resulting in an average of 5 and a maximum of 7 using six studies that referenced
specific numerical values for missing animals or detection rates); review of other states’ programs; and
consideration for building relationships and tolerance for wolves.
● SAG discussion resulted in revising the proposal to include a two-tier ratio without specified rates, with
the recommendation that compensation ratio rates should be determined by a team of experts based
on the best available science.
● There is concern about the limited amount of literature on compensation ratios and disagreement
among studies regarding appropriate compensation rates. There is concern about basing compensation
ratios on other states’ programs, such as Wyoming.
● A compensation ratio could also be used to account for some production losses. The ratio might under
limited circumstances account for some production losses, such as in cases where some missing
livestock may not be due to wolves and producers may still claim them according to eligibility and the
proposed cap. However, the ratios discussed (7 and below) were based on studies that only consider
missing livestock; one study suggests that compensation ratios would need to be 2 to 3 times larger
than the 7:1 ratio used in Wyoming to offset indirect/production impacts.
● Consider an average statewide deduction to account for other losses not caused by wolves and
potentially covered by the ratio.
● As an alternative to requiring that a depredation occur in order to claim missing livestock, consider
using affidavits or contracts to verify presence of wolves in a herd.
● The use of the term “compensation ratio,” rather than “multiplier,” better conveys the limitations of
compensation within a predetermined cap.
● There is concern that verification of nonlethal conflict mitigation practices to confirm eligibility for a
higher ratio could result in a ‘check the box’ exercise; CPW officers could verify practices onsite when
investigating depredations.

Alternative 4: Itemization for compensation of production loss and missing livestock
Overview
SAG members developed an alternative to compensate for depredations (death and injury) at 100% FMV
confirmed according to the proposed new standard above and to compensate for itemized missing livestock and
production losses. Missing livestock claimed (sheep, calves and yearlings only) cannot exceed actual
documented livestock loss and would factor in a baseline (pre-wolf reintroduction) loss rate. General
considerations are provided for how a producer might itemize production losses (losses unaccounted for by
direct depredation, such as decreased weaning weights and decreased conception rates) with reference to
baseline data. The alternative suggests that a depredation incident is required to itemize losses, however other
eligibility criteria could be considered. Conflict minimization practice implementation is not a requirement but
could be considered as an additional incentive for compensation.
SAG feedback (individual comments, not necessarily reflecting consensus):
Rationale for support for Alternative 4
● Support for compensating for losses that wolves have been documented to cause, including missing
livestock and additional production losses. Fair compensation includes direct and indirect losses.
● Provides an opportunity for producers to prove and be compensated for actual impacts and losses due
to wolves, including depredation, missing livestock (without a cap on the actual number of missing

�●
●

livestock that can be claimed), and verified production losses such as decreased weaning and/or
conception rates.
The alternative best compensates the losses that occur once wolves are depredating livestock by paying
the difference between the normal cost of doing business prior to wolf depredation and the additional
losses that occur following wolf depredation.
Supports outcomes of building trust with the livestock community and keeping livestock producers from
being financially harmed.

Rationale for opposition for Alternative 4
● Lack of simplicity for producers and for agency staff.
● Potential fiscal impacts of a program that allows compensation for all missing livestock and production
losses due to wolves.
● Compensation of production losses is too generous; some losses are the cost of doing business.
● Nonlethal conflict mitigation tools are not adequately valued in this alternative.
● The alternative may result in compensation for losses that are not due to wolves (including those due to
other predators and to other conditions such as climate change); this may cause wolves to receive
undue blame for livestock impacts.
Additional considerations for Alternative 4
● Examples provided within the alternative for how a producer might itemize losses are general
considerations; details would need to be further refined. Some concerns were offered regarding how to
construct baseline averages (including how many years are included; the role of drought years in the
average; and the impact of operational size on interannual baselines).
● Consider inclusion of mature cattle, goats and other livestock in itemizing missing livestock.
● Some losses, such as loss of forage, were considered by some as outside the scope of a compensation
program; others supported that they could be addressed through the stipulation for consideration of
other losses on a case-by-case basis.

Alternative 5: Producer chooses between simple compensation ratio (Alternative 3)
OR itemization (Alternative 4)
Overview
SAG members developed an alternative to compensate for depredations (death and injury) at 100% FMV
confirmed according to the proposed new standard above and to allow producers to choose between receiving
a simple compensation ratio for missing livestock (Alternative 3) or itemizing to claim missing livestock and
production losses (Alternative 4).
SAG feedback (individual comments, not necessarily reflecting consensus):
Rationale for support for Alternative 5
● Provides producers with choices to better meet different needs and capacity to itemize losses.
● See rationales for Alternatives 3 and 4 regarding support for compensating for missing livestock and
production losses via compensation ratio or itemization.
Rationale for opposition to Alternative 5
● See rationales for Alternatives 3 and 4 regarding opposition to compensating for missing livestock and

�Additional considerations for Alternative 5
● A compensation ratio may not need to be as high nor as precise in reflecting missing livestock rates
when combined with the opportunity to instead itemize losses.

Alternative 6: Outcome-based compensation in addition to ex post (pay for performance)
Overview
SAG members developed an alternative to compensate producers for depredations at 100% FMV for
confirmation under a preponderance of evidence standard (current game damage program; Alternative 1) and
to provide conservation performance payments for wolf survival, independent of direct or indirect impacts.
Conservation performance payments would be allocated by algorithm, based on a points system considering
wolf pack home ranges, overlap with ranches and livestock exposure/risk, wolf survival to end of year, and
implementation of nonlethal preventative conflict minimization practices.
SAG feedback (individual comments, not necessarily reflecting consensus):
Rationale for support for Alternative 6
● This alternative creates a market-like program that incentivizes desired outcomes: wolf restoration and
presence on the landscape, maintenance of working lands and wildlife habitat, livestock production,
and implementation of nonlethal conflict minimization.
● Provides compensation both for confirmed depredations and additional economic support for the
outcomes noted above. See rationale for support for Alternative 1 for ex post compensation.
● Incentivizes prevention of conflict without requiring any specific strategies or tools.
● Incentivizes finding carcasses in time to get them investigated and compensated for confirmed
depredations.
● Economic approaches suggest that it is more effective to reward the outcomes that society values (both
livestock and wolves staying alive) than to pay for undesired outcomes (i.e., depredation and loss).
Rationale for opposition to Alternative 6
● The outcome-based alternatives lack social and economic certainty to garner adequate buy-in at the
outset of reintroduction.
● The lack of economic data needed to appropriately and meaningfully fund pay for presence limits the
potential effectiveness of the strategy.
● Concern about fairness in distribution of pay for presence funds vs. the actual impacts; wolves could be
present but not depredating in some operations while they are present and depredating in others.
● The alternative does not compensate for all losses that wolves have been documented to cause, such as
missing livestock and production losses. Some suggest that the law requires that these other losses
must be covered. See rationale for opposition to Alternative 1 for ex post compensation.
● Would require increased agency capacity and monitoring.
Additional considerations for Alternative 6
● Continue developing outcome-based alternatives for the future. Outcome-based compensation could
be considered as future program alternatives when more Colorado-specific wolf-livestock
compensation and socioeconomic costs and benefits are available.
● Like all alternatives, cost will increase with wolf population, however individual wolf value can decrease
with population increase.

�Alternatives 7a and 7b: Outcome-based compensation parallel to ex post alternative 1, 2, 3, 4,
or 5 (pay for performance/practices)
Overview
SAG members proposed an alternative to compensate for nonlethal conflict mitigation practices under which
producers could bid competitively to opt out of a parallel ex post program. The producer bid would include
proactive practices as well as the amount the producer would accept to opt out of ex post; proposals would be
reviewed by a board and ranked based on wolf presence, risk, practices, and bid. This alternative can be
complementary to other financial and technical assistance programs for nonlethal conflict minimization. The
approach was suggested by an economist and is based roughly on the competitive bidding process in the USDA
Conservation Stewardship Program.
The distinction between Alternatives 7a and 7b is the parallel ex post program from which the producer bids to
opt out. In 7a, the parallel ex post compensation program is either Alternative 1 or Alternative 2 (compensation
for confirmed death or injury). In 7b, the parallel ex post compensation program is Alternative 3, 4, or 5
(inclusive of compensation for confirmed death or injury, missing livestock, and some production losses).
SAG feedback (individual comments, not necessarily reflecting consensus):
Rationale for support for Alternative 7a and/or 7b
Arguments supporting both options
● The alternative creates a market-like program that incentivizes desired outcomes: wolf restoration and
presence on the landscape, maintenance of working lands and wildlife habitat, livestock production,
and implementation of nonlethal conflict minimization.
● Economic approaches suggest that it is more effective to reward the outcomes that society values (both
livestock and wolves staying alive) than to pay for undesired outcomes (i.e., depredation and loss).
● Incentivizes prevention of conflict, including creative and pooled practices, without requiring any
specific strategies or tools.
Arguments supporting Alternative 7a only
● Providing Alternative 1 or 2 as the parallel ex post program keeps costs lower and provides a stronger
incentive for a producer to bid to opt out in order to receive funding for preventative practices.
● See Alternatives 1 and 2 for rationale for support for these ex post compensation programs.
Arguments supporting Alternative 7b only
● Providing Alternative 3, 4, or 5 as the parallel ex post program gives the producer a choice to opt in or
out of a program that compensates for missing livestock and production losses.
● See Alternatives 3, 4, and 5 for rationale for support for these ex post compensation programs.
Rationale for opposition to Alternative 7a and/or 7b
Arguments opposing both options
● The outcome-based alternatives lack social and economic certainty to garner adequate buy-in at the
outset of reintroduction.
● The lack of economic data needed to appropriately and meaningfully fund this alternative limits the
potential effectiveness of the strategy.
● Increased burden of agency staff in tracking wolf activity and reviewing bid proposals.

Concern about fairness in distribution of pay for performance/practice funds vs. the actual impacts;
wolves could be present but not depredating in some operations while they are present and
depredating in others, including those that implement conflict minimization.

Arguments opposing 7a only
● See Alternatives 1 and 2 for rationale for opposition to these ex post compensation programs.
Arguments opposing 7b only
● See Alternatives 3, 4, and 5 for rationale for opposition to these ex post compensation programs.
● Providing Alternative 3, 4, or 5 for the ex post compensation program is more costly; the funding for the
pay for performance program would need to be scaled to match the funding of the ex post program.
● By covering additional losses (missing livestock, production losses) in the ex post option, the alternative
decreases the incentive for producers to opt out of ex post and to implement preventative practices.
Additional considerations for the Alternatives 7a and 7b
● Continue developing outcome-based alternatives for the future. Outcome-based compensation could
be considered as future program alternatives when more Colorado-specific wolf-livestock
compensation and socioeconomic costs and benefits are available.
● Available funding would need to be adequate to incentivize opting out of ex post.
● Like all alternatives, cost will increase with wolf population; ranking of bids should evolve as wolf
population spreads.

(Nelson 2009; Breck et al. 2011; Dickman et al. 2011; Harris 2020; Macon 2020).

�Appendix B: About the Stakeholder Advisory Group
The Colorado Wolf Restoration and Management Plan Stakeholder Advisory Group (SAG) offers a broad
range of perspectives and experience to inform the social implications of wolf restoration and
management strategies for the Colorado Wolf Restoration and Management Plan. SAG members were
selected by Colorado Parks and Wildlife (CPW) for diversity in demographics, backgrounds, geographic
regions, perspectives, and knowledge in order to constitute a vibrant, diverse and inclusive stakeholder
voice in the planning process. The SAG is comprised of 17 voting members and 3 non-voting members.
CPW is responsible for writing the Wolf Restoration and Management Plan. The Parks and Wildlife
Commission (PWC) serves as the decision-making body responsible for approving the Wolf Restoration
and Management Plan. The SAG serves in an advisory capacity to Colorado Parks and Wildlife, offering
non-binding input into the development of plan content. The SAG is not a decision-making body and has
no authority on wolf management policy, research or operations.
The SAG strives to make decisions based on the consensus of all voting members, where possible.
Where the SAG is able to achieve consensus, its input will receive priority consideration by CPW. Per the
SAG charter, consensus is defined as general agreement that is shared by all the people in a group; it
reflects a recommendation, option or idea that all participants can support or abide by, or, at a
minimum, to which they do not object. In other words, consensus is a recommendation, option or idea
that all can live with. Where consensus does not exist, a vote will be taken and the votes of individual
members will be recorded along with a summary of the rationale for supportive and dissenting views.

Report on Impact-based Management Recommendations
June 2022
Overview

This report summarizes Wolf Restoration and Management Plan Stakeholder Advisory Group (SAG) feedback
on impact-based management recommendations discussed and developed between January 2022 and May
2022.
Discussions resulted in SAG consensus on impact-based management assumptions that support flexibility
through an adaptive management framework. The assumptions include:
● The presence of wolves in Colorado will have both positive and negative impacts.
● Wolves will be left wherever they are if they are not causing problems.
● If wolves show up in places where conflict is likely (e.g., in proximity to livestock), practical
measures should be taken to avoid problems through the use of non-lethal methods.
● If wolves are causing problems, manage to resolve the problem. When negative impacts occur, they
should be addressed on a case-by-case basis utilizing a combination of appropriate management
tools, including education, non-lethal conflict minimization, lethal take of wolves, and damage
payments. Proactive and reactive nonlethal conflict minimization should be encouraged and explored
as a first line of defense, with consideration of individual and community-level approaches. Lethal
management should not generally be a first line of defense, however there may be certain conditions
under which lethal take may be used first to support effective conflict management.
The assumptions also discuss engagement, outreach, and capacity to address impact-based management. The
entire list of consensus assumptions is presented in this report.
The SAG also developed and reached consensus on a variety of elements within an impact-based
management framework for different Phases of wolf reintroduction in Colorado. Phase 1 correlates with
state endangered status; Phase 2 correlates with state threatened status; and Phase 3 correlates with state
delisted, nongame status. Management recommendations are provided for when state authority is in place
(i.e., the species is federally delisted); all management actions will be consistent with state and federal
regulations.
A summary of the framework recommendations is provided here. See the report’s details for specific
permitting, reporting, and investigation requirements; additional considerations; and SAG rationale for support
or opposition for various techniques. Where consensus was not reached, a roll call vote was documented.
Cross-cutting consensus:
● Allow education across all Phases and scenarios.
● Allow nonlethal, non-injurious and potentially injurious conflict minimization techniques, across all
Phases and management scenarios.

�Livestock interactions:
● Consensus:
o Allowance of lethal control by state and federal agents and by producers or their agents for
wolves caught in the act of biting, wounding, grasping, or killing livestock or working dogs.
State statute CRS 33-2-106.4 requires permits for lethal control of a state listed species (in
Phases 1 and 2), as well as reporting and investigation.
o Discretion to CPW to make determination as to whether a situation is characterized as
chronic depredation, and if so, what management actions should be taken, including
whether lethal take should be allowed.
o Allowance of lethal control of chronically depredating wolves following depredation event(s),
after evaluation of circumstances, by state and federal agents across all Phases and by
producers with limited duration permits in Phase 3 (correlating with state delisted, nongame).
o No allowance of translocation of wolves when present but not causing conflict or when
livestock depredation occurs.
● 14 out of 15 SAG voting members supported or did not object to the following; 1 objected:
o Allowance of lethal take of chronically depredating wolves by a producer or agent with a
limited duration permit in Phases 1 and2 (state endangered and threatened).
o Allowance of lethal control by state/federal agents for wolves caught in the act of
chasing in all Phases, and by producers or their agents, with permit and prior
depredation in area required in Phases 1 and 2.
Other wildlife species interactions:
● Consensus: Allowance for consideration of translocation of wolves in Phases 1, 2, and 3, with
considerations, when ungulate populations are significantly below objectives in a geographic unit or
area (i.e., data analysis unit, or DAU) and/or for impacts to other species of concern (e.g., grouse, lynx,
etc.).
● Other items: SAG members did not have consensus regarding lethal control of specific wolves or wolf
packs confirmed by CPW to be having an unacceptable impact on wild ungulate populations in a
geographic unit or area (i.e., a DAU) or to be significantly reducing or likely to extirpate other species
of concern (see discussion and Appendix B for voting results).
Other situations
● Consensus:
o Allow lethal control of wolves involved in attacks on humans.
o Allow removal of a wolf pack denning within municipal boundaries or high-density
population areas.
o Do not allow regulated public hunting of wolves in Phases 1, 2, and 3.
o Allow additional provisions for agency operations, typically involving agreements and
arrangements where state and federal wildlife agencies work in cooperation towards
wildlife management activities.
● Other items: Regarding lethal control of wolves attacking pets and/or hunting dogs, an informal poll
reflected mixed preferences among SAG members across different Phases and options.

�Impact-Based Management Assumptions
The SAG developed consensus impact-based gray wolf management assumptions, which were adapted
from those provided by the 2004 Wolf Working Group.
Consensus is defined as general agreement that is shared by all the people in a group. It reflects a
recommendation, option, or idea that all participants can support or abide by, or, at a minimum, to
which they do not object. In other words, consensus is a recommendation, option, or idea that all can
live with.
The management plan is predicated on managing wolves in Colorado using “impact-based”
management within an adaptive management framework that will allow the state the maximum
flexibility to manage wolves. The assumptions inherent in this impact-based approach are as follows:
Goals and Range of Impacts
a) Goals of impact-based management include restoration of wolves, minimization of conflicts,
minimization of lethal take, and building of trust across communities. Impact-based
management should consider biological, ecological, social, agricultural, and economic
dimensions of wolf management and should recognize and consider diverse perspectives on
these topics.
b) The presence of wolves in Colorado will have both positive and negative impacts.
c) Impacts will vary in intensity and location based on a variety of factors including wolf
distribution, density, and behavior; distribution, species, and density of livestock and wild
ungulates; and land ownership patterns. Some impacts, such as the possibility of increased
tourism, may be viewed as negative or positive by different stakeholders and communities.
d) Negative impacts can include but are not limited to: depredation and harassment of livestock;
loss of pets, herd dogs, and guard animals; dispersal of wild ungulates and possible resulting
property damage; changes in hunting or viewing opportunities; changes in hunting license sales
that could decrease revenue for wildlife management; and declines below management
objectives in ungulate populations and/or in ungulate recruitment rates. Some negative impacts
may be low on a statewide scale but can be acute on a local or individual scale, with social and
economic impacts for those that are affected.
e) Positive impacts, where they occur, should be recognized and utilized, and may include, but are
not limited to: an additional tool for managing ungulates in management units where they are
overpopulated; dispersal of wild ungulates resulting in habitat improvement due to less
pressure on the landscape, especially in riparian areas; a decreased possibility of disease
transmission and/or prevalence (including but not limited to Chronic Wasting Disease) from
ungulate overpopulation and concentration; and social, economic and/or non-monetary values,
such as intrinsic value, existence value, and other possible values for present and future
generations.
Managing Impacts
f) Wolves will be left wherever they are if they are not causing problems.
g) Monitoring of wolf populations, livestock, wild ungulates, other wildlife species, hunter
opportunity and success, and human attitudes is an essential aspect of impact-based
management. Monitoring of other biological, economic and social dimensions may also be
conducted by other actors beyond CPW.
h) If wolves show up in places where conflict is likely (e.g., in proximity to livestock), practical

�measures should be taken to avoid problems through the use of nonlethal methods. CPW and
Wildlife Services – in partnership with Tribes in the case of problems on the sovereign lands of
Tribal nations – will work with livestock producers to investigate, assess the situation, and take
appropriate action. Public and private organizations may also provide support for conflict
minimization.
i) If wolves are causing problems, manage to resolve the problem. When negative impacts occur,
they should be addressed on a case-by-case basis utilizing a combination of appropriate
management tools, including education, nonlethal conflict minimization, lethal take of wolves,
and damage payments. Proactive and reactive nonlethal conflict minimization should be
encouraged and explored as a first line of defense, with consideration of individual and
community-level approaches. Lethal management should not generally be a first line of defense,
however there may be certain conditions under which lethal take may be used first to support
effective conflict management.
j) Flexibility in the array of management tools is essential to accommodate changing
circumstances over time and to allow discretion for managers to consider biological and social
context on the ground.
k) Where the state has jurisdiction, management must be in compliance with federal and state
regulations. Use of management of tools may be phased based on state listing status, balancing
consistency across phases with specific legal considerations.
l) Successful wildlife management includes both public and private lands; provide consistency of
management across land jurisdiction where possible.
m) As with any wildlife management program, the wolf management program will evolve through
time; creative and adaptive management should be applied.
Engagement, Outreach &amp; Capacity to Support Impact-Based Management
n) CPW may, at its discretion, reconvene the Stakeholder Advisory Group and/or Technical
Working Group or other advisory group. This group would assist in finding resolution to
unexpected or non-routine developments that are likely to occur.
o) A high degree of cooperation and coordination among management agencies within the state,
among states, among state and federal partners, and between the state and Tribes is necessary
to ensure that management actions and damage payments are efficient and timely. Cooperation
and coordination between management agencies and the private sector can be beneficial to
support conflict minimization.
p) Education and outreach to foster shared learning and understanding of issues, management
actions, and consequences is a key component of successful wolf management in Colorado.
Effectiveness of education and outreach is impacted by coordination and agreement on
messaging. It is important to provide producers and their agents clarity on allowable actions,
legal parameters, and required permits and/or verifications.
q) Sufficient funds and capacity should be made available to implement all aspects of this plan.

Note that sufficient evidence must be available following lethal control for wolves chasing livestock such that a law enforcement
officer has the ability to determine wolves were in the act of chasing livestock. Without sufficient evidence, lethal control is not
justified for wolves chasing livestock.

Definition of CHASING is from CRS 35-40-100.2(5) as part of "Pose a threat"

Permit required under state law CRS 33-2-106.4. Upon good cause shown and where necessary to alleviate damage to property or to
protect human health, endangered or threatened species may be removed, captured, or destroyed but only pursuant to permit
issued by the division and, where possible, by or under the supervision of an agent of the division. Provisions for removal, capture, or
destruction of nongame wildlife for the purposes set forth in this subsection (4) shall be set forth in regulations issued by the
commission pursuant to section 33-2-104(1). Issuance of a permit accompanied by information and encouragement of nonlethal
tools.

Nonlethal tools should be explored and encouraged before lethal; lethal management should not generally be a first line of defense.
There may be certain conditions under which lethal take may be used sooner or first to support effective conflict management and a
successful recovery (e.g., specific scenarios, situations where non-lethals are less likely to be effective, etc.); managers should consider
context on the ground (biological and social considerations for population growth, pack dynamics and distribution of wolves, recent
and proximal depredations, etc.). Such scenarios where lethal control is implemented must be reported within 24 hours and injured
or dead livestock or dogs or physical evidence that would lead a reasonable person to believe that an attack would occur at any
moment on livestock or dogs must be evident to verify the wolf attack.

While the likelihood of observing a wolf in the act of biting, wounding grasping killing or chasing is rare and the likelihood of
implementing lethal control in this context is also rare, this management approach provides producers with tools to respond, should
the situation occur.

Non-lethal injurious harassment means scaring off a wolf (or wolves) without killing but with potential for minor injury to the wolf
and includes rubber bullets, bean bag projectiles.
Not currently allowed under CPW regulations, previous 10(j) rules have allowed.

Non-injurious harassment of wolves includes scaring off an animal(s) by making loud noises (e.g. confronting the animal(s) without
doing bodily harm). If known injury or death of a wolf occurs, CPW must be notified within 48 hours. Training will be provided by
CPW staff at the time of deployment of materials.

This is an important and effective tool both proactively and reactively to depredation events

Additional /other considerations across phases

This plan is predicated on managing wolves in Colorado using “impact-based” management within an adaptive management framework that will allow the State the maximum flexibility to manage wolves. The assumptions inherent in this impact-based approach are that the presence of wolves in Colorado will have both
positive and negative impacts. The positive impacts of having wolves on the landscape will be recognized and utilized without having to implement direct wolf management practices. The negative impacts of wolves may involve direct intervention. Negative impacts can include but are not limited to: depredation and
harassment of livestock; loss of pets, herd dogs and guard animals; and declines below management objectives in ungulate populations and/or in ungulate recruitment rates. This table describes what the intervention may be implemented to address the negative impacts of having wolves on the landscape. The management
descriptions below will be in compliance with federal and state regulations.

�SAG Consensus/Voting Outcomes and Discussion for Impact-Based Management
Recommendations
SAG members developed and achieved consensus on a variety of impact-based gray wolf management
recommendations, as reflected in the table above and summarized in narrative form in this section. In the
absence of full consensus, roll call votes were taken; the votes are recorded in the tables in Appendix A. For
several items, as noted below, 14 out of 15 SAG voting members supported or did not object; 1 objected.
Phases refer to the following:
● Phase 1 correlates with state endangered status
● Phase 2 correlates with state threatened status
● Phase 3 correlates with state delisted, nongame status
The Technical Working Group (TWG) has developed Technical Recommendations for Colorado State
Listing/Delisting Thresholds and Phasing, in which it provided feedback for specific population recovery
thresholds corresponding to these Phases. The SAG was charged with developing recommendations
regarding management within these Phases. Phases refer to state status, and management
recommendations are provided for when state authority is in place (i.e., the species is federally delisted). All
management actions will be consistent with state and federal regulations.
This section provides a brief summary of consensus or voting outcomes for items in the impact-based
management table, along with brief discussion of rationale for support, opposition (where relevant), and/or
additional considerations. Specific rationales and/or additional considerations reflect a range of feedback from
SAG discussion, and do not necessarily reflect consensus of all members.

Cross-cutting education and nonlethal conflict minimization themes
Consensus items:
● Allow education across all Phases and scenarios.
● Allow nonlethal non-injurious and potentially injurious conflict minimization techniques, across all
Phases and depredation conditions.
Discussion:
● SAG discussion frequently emphasized the impact-based management assumption (i) that proactive
and reactive nonlethal conflict minimization should be encouraged and explored as a first line of
defense, with consideration of individual and community-level approaches. Lethal management
should not generally be a first line of defense, however there may be certain conditions under which
lethal take may be used first to support effective conflict management.
● Discussion also emphasized the importance of outreach and education, particularly for producers
and agents in order to explain what management actions are allowed, and with what permitting,
reporting, and investigation requirements.
● Discussion also emphasized the importance of funding and capacity for wolf management.

�Livestock interactions
Lethal control of wolves biting, wounding, grasping, or killing livestock and workings dogs
The SAG had consensus for allowance of lethal control for wolves caught in the act of biting, wounding,
grasping, or killing livestock or working dogs, as follows:
● Phase 1, 2, and3: Allowed by state and federal agents
● Phase 1 and 2: Limited duration permit for lethal take may be issued to a producer or agent on
private or public land; proof of attack required following lethal take - requires reporting, and
investigation demonstrating evidence to justify act.
● Phase 3: Allowed by a producer or agent without a permit on private and public lands, permissible
for producers to take action on wolves when biting, wounding, grasping, or killing - requires
reporting, and investigation demonstrating evidence to justify act.
Rationale for support
● Allowance of lethal control of wolves caught in the act of biting, wounding, grasping, or killing
livestock is simple to understand and communicate because of the stipulation that wolves must have
‘teeth on’ livestock or working dogs.
● While the feasibility of lethally firing on an attacking wolf is low, this allowance provides a range of
tools for producers to respond to and defend livestock. This flexibility also creates good will and
potentially increases trust.
● State statute CRS 33-2-106.4 requires permits for lethal control of a state listed species (i.e., Phases 1
and 2); allowing producers to lethally take a depredating wolf with no permit in Phase 3 reflects the
change in value of individual wolves as wolf populations grow larger in Colorado.
● Emphasis on nonlethal conflict minimization as a first line of defense is reflected in the provision that
issuance of a permit is accompanied by information and encouragement of nonlethal tools; education
can also be incorporated into the investigation process to minimize future conflict.
● Consistency of rules on private and public lands provides clarity to producers and avoids
difficulty of distinguishing land ownership type.
Additional considerations
● Lethal rounds may be more likely to be on hand than rubber buckshot when responding to caughtin-the-act depredation when no wolves were previously confirmed to be present. Other nonlethal
tools may be limited and less effective when the wolf already has ‘teeth on’ livestock or working
dogs.
● If wolves are known to be in the general area, the process for a producer to obtain a permit
should be streamlined and efficient. Prior depredation is not recommended as a permit
requirement for a wolf that is caught with ‘teeth on.’
● There is some concern for burdensome verification requirements to confirm evidence of wolf
depredation. Emphasize flexibility to allow use of video or photographic evidence when
investigations cannot be conducted in a timely manner. There needs to be clarity of what evidence
is acceptable.

�death or injury to livestock or damaging agricultural products or resources). Refer to Appendix A, Table A-i
for the vote results on the following:
● Phase 1, 2, and 3: Allowed by state and federal agents
● Phase 1 and 2: Limited duration permit for lethal take may be issued to producer or agent on
private or public land based on a prior depredation event (your livestock or in area) - requires
reporting, and investigation demonstrating evidence to justify act.
● Phase 3: Allowed by a producer or agent without a permit on private and public lands,
permissible for producers to take action on wolves when chasing - requires reporting, and
investigation demonstrating evidence to justify act.
Rationale for support
● While the feasibility of lethal control of a chasing wolf is unlikely, allowing producers to attempt to
take chasing wolves may prevent depredation and also creates good will and potentially increases
trust.
● State statute CRS 33-2-106.4 requires permits for lethal control of a state listed species (i.e., Phases 1
and 2); allowing producers to lethally take a depredating wolf with no permit in Phase 3 reflects the
change in value of individual wolves as wolf populations grow larger in Colorado.
● The permit requirement of a prior depredation to a producer’s livestock or in the producer’s area in
Phases 1 and 2 underscores that lethal take of chasing wolves in early Phases is intended to be
directed to wolves that have already been involved in conflict.
● There is potential value in lethally controlling individual wolves who display emboldened behaviors
in order to mitigate production losses to livestock and/or to prevent the whole pack from adopting
these conflict behaviors.
● The experience of producers and agents in the field enables them to determine chasing
behaviors and differentiate them from other behaviors.
● The Technical Working Group (TWG)’s proposed temporal requirements to move from state
endangered to threatened and delisted status mean that wolf populations could be large while still
listed as state endangered, supporting allowance of lethal take at earlier Phases.
Rationale for opposition
● Even with robust education, chasing and testing behaviors are difficult to discern in the field and in the
moment of potential conflict.
● Allowance of lethal take for chasing would create a low bar for someone to use as an excuse for lethal
take when other nonlethal techniques could be used. Chasing behavior provides an opportunity to
train wolves away from livestock using nonlethal techniques.
● Allowance of lethal take for chasing wolves in early Phases may not support a self-sustaining
population and may face public opposition.
Additional considerations
● Provide education to producers and their agents regarding nonlethal techniques that can be used
to deter chasing behavior, and information to understand wolf body language and behaviors.
● There must be robust investigation to verify chasing if a wolf is taken. Use of existing statutory
definitions and ‘necessary to prevent’ language would streamline and simplify standards for
allowance and investigation of chasing.
● There was interest in a clearer definition for chasing to better capture a sense of “imminent
threat;” this could be included in all Phases.
● The definition of a depredation ‘event’ may need to be clarified in the framework as including
death, damage, or injury.

�Lethal control of chronically depredating wolves
The SAG had consensus support regarding control of chronically depredating wolves following depredation
event(s):
● It should be left to the discretion of CPW to make a determination as to whether a situation is
characterized as chronic depredation, and if so, what management actions should be taken,
including whether lethal take should be allowed.
● Allowance of lethal control of chronically depredating wolves following depredation event(s):
o Phase 1, 2, and 3: Allowed by state/federal agents (consistent with federal law) after
evaluation of circumstances.
o Phase 3: Limited duration permits for lethal take may be issued to producer or agent on
public or private land after evaluation of circumstances. Evaluation will consider status and
number of wolves in the state, among other considerations (see Table 1 for details). Permits
will only be issued if state/federal agencies do not have the resources to implement lethal
control actions - requires reporting, and investigation demonstrating evidence to justify the
act.
14 out of 15 SAG voting members supported or did not object, and 1 objected, regarding the following:
Refer to Appendix A, Table A-ii for the vote results on this topic.
● Allowance of lethal control of chronically depredating wolves following depredation event(s):
o Phase 1 and 2: Limited duration permits for lethal take may be issued to producer or agent
on public or private land after evaluation of circumstances. Evaluation will consider status
and number of wolves in the state, among other considerations (see Table for details). Only
issued if state/federal agencies do not have the resources to implement lethal control
actions - requires reporting, and investigation demonstrating evidence to justify the act.
Rationale for support of agency discretion to determine chronic depredation
● Flexibility on a case-by-case basis will allow better development and maintenance of
relationships and trust with livestock producers.
● Discretion allows context-specific evaluation of a variety of considerations such as the status and
number of the wolves in the state, documented repeated depredation and harassment in a limited
geography caused by wolves, previously implemented practices to minimize/reduce depredation,
likelihood that additional and continued wolf related mortality will continue if control is or is not
implemented, and intentional use of attractants that may be luring or baiting wolves to the location.
● Allowing discretion for the agency to determine chronic depredation would be more effective to deal
with outlying or extreme cases of depredation. Chronic depredation may be the exception, rather
than the norm.
● Fixed numeric thresholds (i.e., x depredation in y amount of time) may be too restrictive or too
liberal; do not sufficiently allow for evaluation of the context and conflicts; have not been met with
success in other states; and can damage relationships and trust between agencies and livestock
producers.
Rationale for support of lethal take of chronically depredating wolves
● Support for state and federal agency allowance:
o It is important to lead with trust in and flexibility for state and federal agents to lethally
control chronically depredating wolves.

Final Report of SAG Recommendations, Fall 2022

Wolf Plan Appendix C-59

�The public may be more willing to trust state and federal agents to remove chronically
depredating wolves in earlier stages of reintroduction.
o State and federal agents’ abilities to investigate and track wolves may increase ability to
target the wolves that are chronic depredators.
Support for producer or agent allowance:
o Agency capacity limitations may affect ability to address chronic depredation as the wolf
population grows larger.
o The Technical Working Group (TWG)’s proposed temporal requirements to move from state
endangered to threatened and delisted status mean that wolf populations could be large
while still listed as state endangered, supporting allowance of lethal take by producers at
earlier Phases.
o Although it is preferential, particularly in early Phases, for state and federal agents to
remove chronic depredators, it is important to allow producers to lethally take wolves when
state and federal agencies lack capacity to efficiently address problems.
o It is important to trust agencies to give out permits to landowners judiciously, including in
earlier Phases of reintroduction.
o Landowners may be better situated to respond quickly to chronic depredation,
particularly given the remoteness of their operations as well as the producers’ and
agents’ knowledge of the terrain within which they operate.
o

●

Rationale for opposition of producer/agent lethal take of chronically depredating wolves in Phases 1 and 2
● Allowing livestock producers to take wolves that are state endangered or threatened would be met
with significant public backlash.
● There is concern that producers will not be as effective at targeting chronic depredating
individuals.
● State and federal agencies should be funded to provide capacity to manage chronic depredators at
lower wolf populations.
Additional considerations
● Additional hiring of state and federal agency staff can mitigate capacity issues; adequate funding to
address capacity issues to respond to depredation is needed.
● Clear communication between levels of agency leadership is important in addressing chronic
depredation. Discretion for determining whether a situation meets the characteristics of being a
chronic depredation circumstance, and if so, what management to apply, is addressed at a
programmatic or leadership level; it is not a field-level determination.
● If permits are issued to producers or agents, close communication and coordination between
producers/agents and state or federal agents could improve a landowner’s certainty of effectively
targeting wolves that are chronic depredators.
● Producer permits should be allowed only within defined proximity of investigated and
confirmed livestock depredations.
● Evaluation criteria for defining chronic depredation and determining management actions should
be used as examples within a holistic framework, rather than a prescriptive checklist.
● A policy statement on lethal control for chronic depredations could be crafted based on
literature review, e.g., “Lethal control of wolves is appropriate when conflicts are likely to
continue, nonlethal methods have been attempted and/or are unlikely to be successful,
domestic animals were clearly killed by wolves, and there is no evidence of intentional feeding
or unnatural attraction of wolves. If implemented, lethal control should be targeted to wolves
involved in conflict, swift, effective, as humane as possible, and closely monitored.”

Do not consider translocation of wolves when present but not causing conflict. Translocation
should also not be considered to displace depredating wolves to other areas where they may
continue to cause conflict.
The definition of a depredation ‘event’ may need to be clarified in the framework as including
death, damage, or injury.

Other wildlife species interactions
The SAG had consensus for consideration of allowance of translocation of specific wolves or wolf packs
confirmed by CPW to be having an unacceptable impact on wild ungulate populations in a geographic unit or
area (i.e., a DAU) and/or for impacts to other species of concern (e.g., threatened and endangered species
such as grouse, lynx, or other species of conservation need etc.).
The SAG discussed but did not have consensus for the following: Refer to Appendix A, Tables A-iii and A-iv
for the vote results on these topics.
● Lethal control of specific wolves or wolf packs confirmed by CPW to be having an unacceptable
impact on wild ungulate populations in a geographic unit or area (i.e., a DAU):
o Not allowed in Phases 1 and 2. (10 out of 15 SAG voting members supported or did not
object; 5 objected)
o Allowed with considerations in Phase 3 (see table for details of considerations). (12 out of 15
SAG voting members supported or did not object; 3 objected)
● Lethal control of specific wolves or wolf packs confirmed by CPW to be significantly reducing or likely
to extirpate other species of concern:
o Not allowed in Phases 1 and 2. (8 out of 15 SAG voting members supported or did not
object; 7 objected)
o Allowed with considerations in Phase 3 (see table for details of considerations). (13 out of 15
SAG voting members supported or did not object; 2 objected)
Rationale for support for translocation of wolves:
● Translocation of wolves should be considered if wolves cause ungulate populations to decline to
below objective in a given management area, or if other species of concern are impacted.
● Translocation would redistribute impacts of wolves to areas where ungulate herds or other
species of concern are less likely to experience significant impact.
● Translocation of wolves for the above reasons may be more effective at earlier Phases of restoration
and less effective when a larger population of wolves is widely dispersed throughout Colorado.
Rationale for support of lethal take of wolves impacting ungulates or other species of concern:
In any Phase:
● Flexibility of management tools to respond to impacts on ungulates should be similar to those
available for livestock interactions.
o Livestock producers have more options for addressing and/or being compensated for
impacts than hunters or outfitters.
o Short of translocating wolves, the primary option to relieve impacts on ungulates
without lethal take of wolves is to decrease hunting opportunities.
● Impact-based management of wolves for impacts to ungulates should include ability to respond to
local impacts that may be acute in one region even if there are not impacts across the state.

Final Report of SAG Recommendations, Fall 2022

Wolf Plan Appendix C-61

61 of 107

�Local impacts of concern could include decline in ungulate populations leading to
decline in cow hunting licenses, upon which many Colorado families depend for an
annual meat source.
o Ability to respond to local impacts with lethal control can also mitigate impacts to CPW’s
overall funding, which relies heavily on hunting licenses including from out-of-state hunters.
There is concern for a decline in interest from out-of-state hunters due to perceived negative
impacts from wolves on the landscape.
Though unlikely to occur, flexibility to respond to impacts to other species of concern should be
allowed in any Phase; Colorado has invested resources in a variety of species of concern.
o

●

In Phase 3 only:
● While likelihood of need for and use of lethal take to control wolf impacts to ungulates or other
species may be low, higher wolf populations in Phase 3 support flexibility for lethal take, with
considerations as described in Table 1. This flexibility would be accompanied by multi-year data or
other information, collected through Phases 1 and 2, indicating that wolves are a major cause of
ungulate herds not meeting objectives or of significant impacts to other species of concern.
Rationale for opposition of lethal take of wolves impacting ungulates or other species of concern:
In any Phase:
● Wolves are natural predators of ungulates and thus should not be managed for their natural
behavior.
● Wolves’ natural predation of ungulates should not be considered a negative impact; wolves may prey
more frequently on elderly or sick elk, creating a healthier herd overall.
● There should be a high standard of evidence that wolves are the cause of decline of ungulate
populations. Other environmental factors (e.g., climate and disease) contribute to impacts on
ungulates and other wildlife species.
In Phases 1 and 2 only:
● Insufficient time to collect multi-year data on impacts of wolves to ungulates or species of
concern, and lower wolf populations, would not support lethal take of wolves for impacts to
ungulates or other species of concern early in restoration.
Additional considerations
● Use a standardized unit of area to guide evaluation of wolf impact. Specifically, use a data
analysis unit (DAU), which has precedence guiding ungulate management objectives.
o SAG members discussed whether DAUs apply to every management scenario in Colorado
for which lethal take of wolves due to impacts on ungulates would be considered. Some
suggested special management units may need to be considered as well to align with
existing management and because wolf effects on ungulates may occur at scales smaller
than a DAU.
o Others suggested DAUs are the only appropriate metric. DAUs are the smallest scale at
which CPW conducts sampling, surveying, and modeling for ungulates.
o Detecting and measuring effects at smaller scales may be challenging because of animal
movements within the DAU, and a special, targeted monitoring scheme, if designed, would
not be consistent with how CPW manages other ungulate populations.
o CPW should determine which unit area metrics are appropriate.
● There were calls to better understand:

Final Report of SAG Recommendations, Fall 2022

Wolf Plan Appendix C-62

62 of 107

�Impacts on elk herds like habitat loss from fires, population growth, and climate change, along
with the number of elk a wolf is expected to take each year, and subsequent impacts on the
number of elk licenses made available and declines in agency revenue.
o How quickly the agency would be able to respond to impacts that are measured through
studies.
SAG members discussed relevance of the North American model of wildlife conservation for these
scenarios; some suggested the model could be interpreted to support management of wolves for
impacts to ungulates; others expressed concern that this model is not suitable for wolf
management because of the wolf’s current status as an endangered species and because current
law prohibits use of license fees for wolf management. Further, various stakeholders have differing
views on the model’s historic and present success.
Consider additional activities to manage ungulates to proactively mitigate and/or avoid any
potential significant declines to ungulate populations that could impact hunters, outfitters, livestock
producers that use hunting/outfitters as an additional income source, and rural economies; and to
mitigate the kind of social conflict ongoing in the Northern Rocky Mountain states. More detailed
discussion of opportunities for management of ungulates will occur separately.
o

●

●

Other situations
The SAG had consensus on management for the following additional situations:
● Allow lethal control of wolves involved in attacks on humans.
● Allow removal of a wolf pack denning within municipal boundaries or high-density population
areas.
● Do not allow regulated hunting of wolves in Phases 1, 2, and 3.
● Allow additional provisions for agency operations, including lethal and nonlethal take by state or
federal agencies for scientific purposes, to avoid conflict with human activities, to relocate a wolf to
enhance survival and recovery prospects, to aid or euthanize sick, injured wolves, to salvage dead
specimens, to aid in law enforcement investigations involving wolves, and to manage wolves with
abnormal physical or behavioral characteristics.
Regarding lethal control of wolves attacking pets and/or hunting dogs, no formal roll call vote was taken.
● An informal poll of SAG members’ preferences was taken in lieu of robust conversation due to time
constraints and SAG feedback regarding prioritization of this discussion topic. The informal poll
reflected mixed preferences among SAG members across different Phases and options. Allowance of
lethal take of wolves when attacking pets generally received more informal opposition and more
responses of ‘no preference’ than allowance of lethal take for wolves when attacking hunting dogs.
● Brief discussion of considerations to allow lethal take of wolves attacking pets included:
o Concern for a lower standard to allow take of wolves attacking pets compared to livestock (i.e.,
no permit required for take of wolves attacking pets); the existing standard for bear and lion
does not allow lethal take when attacking pets, however there is potential for interspecies
aggression among wolves and dogs; pets should be managed, rather than wolves, to avoid
conflicts; and consideration of pets’ role as ‘family’ members. Members suggested not allowing
lethal take of wolves only chasing rather than biting/wounding/killing) pets.
o Additionally, some members suggested a different allowance for lethal take when wolves
attack hunting dogs, given hunting dogs’ role in wildlife management and/or their role in
and cost to hunters and hunting and outfitting businesses.

The Colorado Wolf Restoration and Management Plan Stakeholder Advisory Group (SAG) offers a broad
range of perspectives and experience to inform the social implications of wolf restoration and
management strategies for the Colorado Wolf Restoration and Management Plan. SAG members were
selected by Colorado Parks and Wildlife (CPW) for diversity in demographics, backgrounds, geographic
regions, perspectives, and knowledge in order to constitute a vibrant, diverse, and inclusive stakeholder
voice in the planning process. The SAG is comprised of 17 voting members and 3 non-voting members.
CPW is responsible for writing the Wolf Restoration and Management Plan. The Parks and Wildlife
Commission (PWC) serves as the decision-making body responsible for approving the Wolf Restoration
and Management Plan. The SAG serves in an advisory capacity to Colorado Parks and Wildlife, offering
non-binding input into the development of plan content. The SAG is not a decision-making body and has
no authority on wolf management policy, research, or operations.
The SAG strives to make decisions based on the consensus of all voting members, where possible.
Where the SAG is able to achieve consensus, its input will receive priority consideration by CPW. Per the
SAG charter, consensus is defined as general agreement that is shared by all the people in a group; it
reflects a recommendation, option or idea that all participants can support or abide by, or, at a
minimum, to which they do not object. In other words, consensus is a recommendation, option or idea
that all can live with. Where consensus does not exist, a vote will be taken and the votes of individual
members will be recorded along with a summary of the rationale for supportive and dissenting views.

Report on Ungulate Management Recommendations
August 2022
This report summarizes consensus recommendations of the Colorado Wolf Restoration and
Management Plan Stakeholder Advisory Group (SAG) regarding strategies to manage ungulate
populations and hunter opportunities in the context of wolf reintroduction and management.
In conjunction with the recommendations made in this report, the SAG’s report on impact-based
management also provides insight on direct management of wolves in response to ungulate populations
significantly below objectives that can be caused by wolf predation.

Discussion
Although impacts to outfitters and hunters are not addressed in Proposition 114, the SAG feels it is
important to address them as part of the plan. A SAG member reported the concern that some
members of the hunting community are not supportive of how their concerns have been addressed
within the SAG process. Many SAG members are concerned that the tension and frustrations that have
led to anti-wolf policies experienced in Idaho and Montana are beginning in Colorado. SAG members
encourage the Commission to work early and proactively to address these tensions and frustrations.
The SAG understands that it is difficult to predict specific numerical impacts and location of impacts of
wolves on ungulates. Wolves may bring about negative impacts at localized levels to certain ungulate
populations while some herds may be largely unaffected with little to no impacts. Additionally, wolves
may help certain populations become healthier through predation and altering habitat use.
While these outcomes will play out as wolves repopulate western Colorado, the real and perceived
social and economic impacts are already present among the hunter/outfitter community. There is
concern that wolves will reduce hunter opportunity due to declining herd numbers, deer and elk will be
pushed out of designated permit areas that outfitters operate in and result in their businesses not being
able to provide the services they are permitted to provide, and numerous other concerns. For more
detailed descriptions on both the positive and negative impacts wolves may have on a localized level,
the SAG recommends reviewing the impact-based management report.
Whether it’s positive or negative impacts being discussed, the SAG recognizes there is some speculation
involved about impacts in Colorado based on science and previous observations where wolves have
been present. It would be beneficial for CPW and Colorado to develop proactive measures prior to wolf
restoration that will address potential impacts to livestock producers or hunters and outfitters.
Therefore, it is critical for CPW to develop a proactive approach to potential and perceived negative
impacts that may stoke greater barriers to sustainable wolf populations and deliver clear and consistent
messaging on the handling of wolf/ungulate interactions. In this way, CPW can create trust and buy-in

�from the public and contribute to the long-term sustainability of both wolves and ungulate populations
and ultimately individuals and communities living with them in Colorado.
Based on evidence and direct communication with biologists from the Northern Rockies, if and where
impacts occur, they will be at a local level (in Colorado, likely at a DAU or GMU scale). Local level impacts
on ungulates, both real and perceived, may have an outsized role in catalyzing opposition to wolves and
may serve as one of the greatest long-term challenges to wolf sustainability. Monitoring will be key to
understanding impacts and responding accordingly through impact-based management (see the SAG’s
impact-based management report for more on this topic).
The SAG understands that wolves alone are not the focus of ungulate management but another layer
that must be incorporated into the current models. Ungulates face multiple stressors including but not
limited to ever-increasing non-consumptive recreational impacts, multiple predators, habitat
encroachment/loss, drought/aridification and more. With all these factors in mind, it is important to
remember CPW’s main tool for ungulate population management is through hunting. Managed hunting
of ungulate game populations provides the backbone source of revenue for CPW, provides numerous
outlets for economic activity, and provides an extremely valuable source of protein/food.
In closing, the SAG offers the following recommendations, understanding that there is not a collective
assumption wolves will negatively impact ungulate herds. Rather, these recommendations are offered
for consideration of how to manage already existing concerns and proactively address them should they
occur in the future. The details of such recommendations would require further discussion.

Recommendations
●

Prioritize, ramp up and maintain monitoring of ungulate populations and actively manage for
impacts at a local level. Where consistent monitoring identifies localized impacts (causespecific), integrate data into the planning and management strategies at the local level. Causespecific factors could include habitat fragmentation, increased recreation, or drought, along
with predation.

●

Continue growing ungulate herds. The SAG recognizes that CPW is making efforts to bring
certain ungulate populations that are currently below objective back within objective. In this
vein, the SAG would suggest continuing these efforts, as well as proactively expanding efforts to
grow ungulate herds on a GMU or DAU basis, particularly where wolves are predicted to occupy,
and managing/maintaining these herds at the upper end of objectives. This approach could
provide a win-win in the sense that an abundance of ungulates will provide a buffer against
potential wolf-caused population decline, provide ample prey base for rapid and successful wolf
population growth, and, if population declines fail to appear over time, the opportunity will exist
to increase hunt-based ungulate management. Additionally, prioritize wolf release sites where
ungulate populations are NOT under objective. This recommendation should be taken into
consideration in addition to other ungulate management factors.

●

Develop and implement an Education and Outreach communications campaign. A consensus
recommendation from the SAG is to create an active communications campaign for target
audiences. CPW should provide education and outreach that gives consistent baseline
information for agency actions with respect to ungulate management (license allocation, quota

Wolf Plan Appendix C-71

�reduction, herd counts, etc.) and science around Colorado’s wolves, in order to mitigate
controversies with best available science and provide transparent, relevant, and easy-tounderstand information to impacted communities. This recommendation hinges on a proactive
approach to outreach by putting information into the hands of the public vs. the public needing
to seek it out. In reference to this recommendation, CPW has stated the cost of $1.7 million to
pursue the next levels of outreach and social science driven education. More specific details on
this communications campaign are provided in the attached addendum. Refer as well to the
SAG’s recommendations on outreach and education for more on these topics.
●

Consider a compensation program for affected outfitter businesses and/or clients. See
attached documents on other state voucher/set aside programs. There are a variety of options
the SAG discussed with this recommendation. The basic premise revolves around outfitters
whose permitted area shows a data-backed connection between declining ungulate herds and
wolf predation. CPW may provide vouchers to these affected operators that could provide an
alternate means of generating revenue for the outfitter, thereby keeping their business alive
until a wolf/ungulate balance is achieved. Alternatively, CPW could create or support other
compensation avenues for outfitter businesses that cannot provide services related to wolf
presence. A separate compilation of data directly from the Northern Rockies’ state wildlife
agencies is being submitted separately but in conjunction with these recommendations. As a
related concept, consider working with the US Forest Service, Bureau of Land Management, and
private landowners, as applicable, to explore reserved common permits for outfitters.

●

Create new opportunities and promote current opportunities for the public to provide nonhunting income to support wolves and wildlife management. This recommendation stems
from the idea that those who voted for Proposition 114 and want wolves on the landscape
should have the opportunity to provide financial support to CPW for the management of wolves,
impacts on ungulate populations, and habitat to support both. Refer as well to the SAG’s
recommendations on funding for more on these topics.

●

Solidify robust and consistent funding. The SAG recognizes that robust and consistent funding is
necessary to accomplish the recommendations above. Solidifying reliable and adequate sources
of additional funding to implement ideas such as a top-notch communications campaign and
increased monitoring are paramount to the success and associated costs of Colorado wolves,
while also maintaining the ungulate populations that CPW and hunter dollars have invested so
much in already. In the 2022 budget, the General Fund provided $2.1 million for wolf planning.
A preliminary estimate for actual needs would be an amount of up to $3 million annually for
funding of directly related expenses; this number could potentially be more when considering
adjacent expenses that are indirectly or partially related to wolf restoration and management,
for example research and communications. Refer to the SAG’s recommendations on funding for
more on these topics.

Conclusion
The SAG recognizes the issue of ungulate management is challenging and highly variable. Ultimately,
CPW staff and the CPW Commission are tasked to take actions that are best for a successful wolf
recovery in conjunction with maintaining healthy ungulate populations and maintaining hunter
opportunity.

�Appendix:
Avoiding Real and Perceived Loss of Hunting Opportunity and Montana/Idaho Outcomes
Additional input provided by Adam Gall and John Howard
Whether wolves will greatly impact hunting opportunity and/or success is difficult to determine
due to the number of variables at play. In looking at data from the Northern Rockies, we believe
the impacts will be at a localized level. Sometimes as specific as a particular creek drainage or
basin where wolves might or will impact the presence of elk.
This presents an opportunity to take early proactive action in the field and in communications to
avoid the Montana/Idaho Outcomes. To change the narrative.
Biologists in MT and ID report the failure to take more proactive action scaling back elk licenses
in areas of predation (from many species) was a missed opportunity. It allowed a largely data
free narrative to develop over time born out of the frustration with the absence of various state
and federal actions and engagement. Working with the data and experiences from the
Northern Rockies, these are a few suggestions for the Commission to proactively avoid the
Montana/Idaho outcome:
1) Continue growing the elk herds. While efforts to do so have been under way for the
past several years, we believe the hunting community fails to understand this effort. In
addition, this conversation tends to be tags versus predators and now wolves. While
reduction in cow elk harvest is an important lever in elk population growth, there are
many factors: other predator control (lions in particular, bears in the spring), drought
mitigation, conservation of calving and winter range, habitat improvement, recreation
planning and restraint. CPW knows how to manage elk, but two public announcements
we believe would cause immediate relief and support in the hunting community. We
have trial tested these ideas with various leadership levels of major conservation groups
in Colorado and received an overwhelmingly positive response.
a. Raise the elk herd population goal publicly (consider deer and moose);
b. When the agency considers localized conditions within a DAU/GMU where
wolves are present or likely present in the future, the agency will consider a
larger population goal for that DAU/GMU.
c. This comes at the expense of short-term loss of opportunity for hunters,
potential for increased damage on livestock operators, and a decrease in
revenue for CPW. However, the increased herd numbers should offer mediumand long-term greater hunting opportunity countering any actual or perceived
narrative blaming wolves for elk population decline. If such a growth is
unneeded in the future, CPW knows how to manage the population down.

�d. Such a strategy can unite the diverse stakeholders around greater food sources
for wolves, preserving and perhaps expanding hunting opportunity, and most
importantly avoiding the Montana/Idaho outcome.
2) Targeted Active Communications Campaign – The Critical Step
a. CPW should retain a Colorado based advertising agency with experience in
conservation. A model is GOCO’s Generation Wild campaign, although on a much
smaller and targeted scale;
b. An advertising agency should be retained to work with agency staff to design a
proactive communication plan with the following goals:
i. Provide a baseline of information for the agency’s actions;
ii. Provide a baseline of information for science around Colorado’s wolves;
iii. Address controversies with the best available science;
iv. Provide impacted communities with information in forms and format
they accept and understand.
c. Tactics
i. Target impacted communities;
ii. Receive back in real time effectiveness of such communication (this is not
only possible in social media now, but also traditional media);
iii. Adjust immediately to real time feedback to improve communications;
iv. Explain transparently what actions the agency is taking;
v. Explain transparently the science from CPW’s research;
vi. Lead the conversation, don’t react to it;
vii. Always seek to target messages appropriately to different groups across
the state – addressing not just what they want to hear but also what they
do not want to hear, but on their terms.
d. How is this different from CPW’s current communications?
i. It’s active – it takes particular messages out across multiple channels in a
coordinated fashion;
ii. CPW is great at passive communication of data – “It’s all up on the
website”.
iii. Our proposal takes that mountain of data and shapes it into succinct
messages – “wolves do not impact hunting” or “wolves do impact
hunting locally, but our planning has accounted for it” or “elk populations
are up and we are in a new golden age of hunting”.
iv. Not propaganda, but a compelling invitation for greater engagement with
the facts on the ground.
v. GOCO could have put data on how the outdoors impacts kids and moms
on a website. What made Generation Wild a success was the active
engagement via media, games, contests, events, and other tactics that
drove the message that Moms and Kids in the outdoors is key to health
and a happy life.

�Colorado Wolf Restoration and Management Plan
Stakeholder Advisory Group (SAG)
to Colorado Parks and Wildlife (CPW)
Statement on Regulated Public Hunting of Wolves
July 2022
Overview &amp; summary of key points
This report summarizes feedback from the Colorado Wolf Restoration and Management Plan Stakeholder
Advisory Group (SAG) regarding regulated public hunting of wolves.
1. The SAG does not have consensus on whether to allow regulated public hunting of wolves. The
SAG has not sought a formal vote nor consensus on this topic.
2. The SAG recommends, by consensus, that a decision on regulated public hunting of wolves
should not be made in the restoration and management plan to be finalized in 2023. The SAG
recommends that it is premature for a decision to be made on regulated public hunting in the
upcoming 2023 plan. The SAG recognizes that any decision on this topic would only be relevant if
wolves have achieved a self-sustaining population in Colorado as required by 33-2-105.8. The
SAG further recognizes that these conditions will not be relevant, if at all, for many years. Some
SAG members are concerned that a decision on regulated public hunting in the planning process
may overshadow other key elements of the plan and that it should not be decided at this time.
Other SAG members suggest that while they agree it should not be decided upon now, it is
important for the Commission to discuss the topic prior to state delisting. Other SAG members
believe public hunting of wolves should not be allowed.
3. The SAG recommends, by consensus, that any future discussion and/or decision on regulated
public hunting of wolves should be impact- and science-based, with consideration of biological
and social science as well as economic and legal considerations. The SAG anticipates that an
abundance of biological, social, and economic data and information will be gathered when
wolves are reintroduced to and are present in Colorado over time. The SAG recommends that
this information be used to inform future decision making regarding regulated public hunting,
along with consideration of interpretation of legal authorities relative to the definition of gray
wolves in CRS 33-2-105.8. Some SAG members feel it is premature to detail the considerations
that should inform a future decision.
4. The SAG recognizes, by consensus, that the concept of regulated public hunting is distinct from
targeted lethal control. The SAG provided feedback on targeted lethal control of wolves in its
June 2022 report on impact-based management. Within the consensus impact-based
management assumptions in that report, the SAG recommended, ‘when negative impacts occur,
they should be addressed on a case-by-case basis utilizing a combination of appropriate
management tools, including education, non-lethal conflict minimization, lethal take of wolves,
and damage payments.’ The SAG also offered consensus recommendations in that report
regarding allowance of targeted lethal control in specific situations.

�Colorado Wolf Restoration and Management Plan
Stakeholder Advisory Group (SAG)
to Colorado Parks and Wildlife (CPW)
Report on Outreach and Education
August 2022
Overview and guiding recommendations
This report summarizes feedback from the Colorado Wolf Restoration and Management Plan
Stakeholder Advisory Group (SAG) regarding outreach and education, including 1) consensus
recommendations described on this page and 2) a compilation of suggestions for specific audiences and
messages offered by each sector of the SAG.
The SAG offers, by consensus, the following priority recommendations regarding the value and need
for outreach and education:
1. Targeted outreach and education are an essential component of a successful restoration and
management program that can increase trust, transparency, and awareness.
2. Substantially increase funding for education and outreach; effective outreach and education
requires robust agency capacity, dedicated funding, and resources.
The following consensus recommendations should also guide outreach and education related to wolf
management:
● Outreach and education should occur proactively, continuously, and reactively.
● General as well as audience-specific messages and mechanisms are needed; diverse audiences
use and/or prefer different communications approaches and formats, including bilingual
messaging.
● Include messaging about what is in the plan; agency actions and how the plan is being
implemented; goals and expectations; and positive and negative impacts of wolves at various
scales.
● Identify trusted messengers; consider where trust in the agency is strong or weak as a potential
lever or barrier to effective communication.
● Common messaging should be amplified through partnerships; there is power in diverse
stakeholders communicating similar messages to their sectors.
● Messaging can help build awareness and empathy for different perspectives; highlight how
different stakeholders are working together across different points of view; and illustrate
impacts with personal stories.
● Social science research can help inform outreach and education strategies and messages; the
effectiveness of communications tools and messaging should be monitored to inform and adapt
them for greater success.
● Outreach and communication should highlight opportunities for a variety of
interests/stakeholders to support funding of the wolf plan.
● Balance information on wolves with other wildlife messaging; wolves are a member of the suite
of native species in Colorado.
● Counter misinformation and misperceptions with best available science.

�Key messages by audience
The SAG has discussed a variety of potential audiences for outreach and education. The following
sections synthesize feedback on key messaging topics, by target sector. They are offered as a
compilation of feedback from SAG discussion and do not necessarily reflect SAG consensus on all points.
Messages suggested for the agriculture, sportsperson, and wolf advocacy sectors reflect the compilation
of feedback from breakouts of each of those sectors, respectively; they are not necessarily a reflection
of SAG consensus nor consensus of the broader constituencies of each sector beyond those that
participated in each of the SAG sector discussions. Messages suggested for outdoor recreationists, local
and municipal decision makers, and the general public are a compilation of messages suggested by all
SAG members; once again, they do not necessarily reflect consensus on all points.

Agricultural community (messages suggested by SAG agriculture members)
Key messages to provide to the agricultural community:
● Describe what the management plan says and relevant issues for livestock producers.
Specifically, describe options available for compensation, conflict minimization, and use of
nonlethal or lethal tools; the resources that are available and how to access them; and the
reporting and investigation process.
● Producers are valued; ranching and open space benefits and ecosystem services are valued.
● Impacts will be local; impacts to specific producers can be significant while statewide impacts
are small.
Key messages the agricultural community would like to get across:
● Ranching supports wildlife by providing connections and habitat across public and private lands;
private lands are necessary for wildlife habitat, especially animals’ winter range.
● Livestock producers do not hate wolves.
● Livestock producers want to keep livestock alive, healthy, happy, and safe; producers do not
want to see livestock suffer.
● Livestock compensation does not cover all costs to producers; stress and mental health issues
are real and significant; the agricultural community would like to understand what financial
support others are willing to provide to support wolf restoration.

Sportspersons and outfitters (messages suggested by SAG sportspersons/outfitters members)
Key messages to provide to sportspersons and outfitters:
● There is a plan to manage wolves and the species’ reintroduction.
● Impacts will be local, not statewide.
● There is a strategy to stabilize and maintain ungulate populations and to grow populations
where possible, with consideration of all impacts, including to wolves.
Key messages the sportsperson and outfitter sector would like to get across:
● Sportspeople are the key component of financial support and physical support for science-based
wildlife management.
● Over time, wolves should be managed like all wildlife.

�Wolf advocates (messages suggested by SAG wolf advocacy members)
Key messages to provide to wolf advocates:
● There will be impacts to individuals and communities from wolves.
● It is important to understand the concerns of impacted individuals and local communities.
● There will be compensation for livestock losses by law, but producers sometimes are unsatisfied
with the programs as they feel they do not compensate for all losses, leading to decreased
tolerance for wolves.
● Wildlife management takes effort and money.
Key messages wolf advocates would like to get across:
● There are positive impacts of wolves, including restoring biodiversity and wildlife diversity;
tourism and economic benefits from wolf-based tourism; and contributing to healthier riparian
systems (e.g., more songbirds).
● Wolves will not decimate ungulate populations or the livestock industry.
● (Particularly for the agricultural community) Most wolves do not kill livestock; some do.
● Wolves do not pose a significant threat to human safety.
● Wolves should not be managed like all other wildlife (e.g., advocates do not have a favorable
view of management of bears and cougars).
● Even when they are distributed throughout western Colorado, wolves will be far less common
than coyotes, black bears, or cougars.

Outdoor recreationists (The following messages are a compilation of messages suggested by all SAG
members. The suggestions do not necessarily reflect consensus on all points.)
Key messages to provide to outdoor recreationists:
● Historically, wolves do not attack people; wolves pose no significant personal danger to human
safety.
● Wolves may approach you out of curiosity. Know what to do if approached.
● Your activity, presence, and pets have an impact on wildlife and habitat, including wolves.
● There will not be significant loss of recreation opportunity due to wolf reintroduction or their
presence on the landscape.
● Be aware of wolves’ impacts on lands used for recreation, including positive impacts such as the
opportunity to wildlife watch and negative impacts such as potential closures due to denning
sites.
● Recreation benefits from wildlife management; encourage recreationists to contribute directly
to wildlife and wolf management and make options for contribution clear (i.e., emphasizing
“donate now” opportunities on the CPW website).
Additional FAQ and best practice considerations for messaging to outdoor recreationists:
● What to do if you see a wolf.
● Leash your dog: it is safer on leash for wildlife and your dog.
● Wolves are wild animals: give them space and do not approach or feed them.
● It is illegal to chase or harass a federally endangered species.
● Don’t handle wolf scat.
● Wolf pups likely aren’t abandoned; leave wolf dens alone.

How to report wolf sightings to local CPW offices.
(For hunters) Lead bullet fragments left in carcasses [gut piles] can cause lead poisoning of
scavengers; switching to copper bullets can help.
Don’t leave stock tied up in vulnerable areas.
The difference between coyotes and wolves: e.g., tracks, scat (use pictures/graphics).
Proper food storage practices.
Include wolves in existing messaging for bears, cougars, etc.
Provide information near wolf locations (i.e., at visitor centers and trailheads; use QR codes).

Local and municipal decision makers (The following messages are a compilation of messages

suggested by all SAG members; however, the suggestions do not necessarily reflect consensus on all
points.)
Key messages to provide to local and municipal decision makers:
● The benefits and costs to reintroduce and manage wolves in their area.
● General facts about wolf biology; the wolf reintroduction and management plan; plans for
livestock compensation, ungulate management, and conflict mitigation.
● We are counting on decision makers for accurate messaging to the broader public.
● Wolf impacts tend to be more localized and may impact individual producers rather than entire
regions; local decision makers can help messaging to have an appropriate scale.
● Facts about what resources are available to impacted constituents.
Additional considerations for messaging approaches to decision makers:
● Work with local leadership first; be proactive in their role in communicating with the broader
public; emphasize the importance of local leadership in communication.
● Emphasize the importance of decision makers’ partnership with CPW; leverage relationships
between local CPW staff and leaders.
● Leverage existing groups (e.g., CCI, Club 20, Action 22) to hold workshops on wolf restoration
and management.
● Use factsheets to make information accessible and easily digestible.
● Local leaders are an important source of information at the local scale and can communicate
issues in their communities.
Key messages decision makers would like to get across:
● We are here to support our constituencies.
● We have/need the resources to support you.

General public (The following messages are a compilation of messages suggested by all SAG
members; however, the suggestions do not necessarily reflect consensus on all points.)

Key messages to provide to the general public:
● The plan, timing, and process of wolf reintroduction (e.g., ‘We are bringing wolves to Colorado
by the end of 2023.’)
● Why wolves are being reintroduced when they are already here and why the state is spending
money on restoration efforts.
● We don’t have to choose among ranching, hunting, and restoration.
● This is a historic moment for Colorado.

General facts about wolf biology (wolves are a native species and being restored to the state).
Funding for wolf restoration is currently being allocated from the general fund.
We need funding to protect animals and reduce conflict with livestock.
CPW is the authority of correct information; the agency is made up of experts on this topic.
Management is impact-based and adaptive.
Impacts from wolves may be positive or negative.
The wolf planning process actively engages a diverse set of stakeholders to inform a plan that
acknowledges and strives to address a variety of concerns.
Ungulate populations are impacted by a variety of factors.

Additional considerations for messaging approaches to the general public:
● Focus on the middle ground; highlight personal stories; showcase intersectionality of interests.
● Highlight systems and processes in place for wolf issues.
● Direct delivery: local television, radio, businesses, professional sports teams, op-eds, news
articles.
● Address myths about safety with education.
● Humanize CPW; increase agency transparency with the public.
● Review images and graphics to ensure they are accurate to the real world (e.g., photos of
livestock guard dogs, not burros; pictures of livestock on the range and not dairy cows).

�Colorado Wolf Restoration and Management Plan
Stakeholder Advisory Group (SAG)
to Colorado Parks and Wildlife (CPW)
Report on Funding Recommendations
June 2022
The following funding recommendations reflect the consensus of the Wolf Restoration and
Management Plan Stakeholder Advisory Group (SAG).
The SAG recognizes that wolf restoration and management will be accompanied by both positive
economic benefits and localized personal negative economic impacts, especially to our more rural
neighbors. To the extent possible we all should try to equitably distribute those positive economic
benefits and mitigate the negative impacts.
Short-term and long-term funding will be necessary for a variety of needs related to wolf restoration
and management, including but not limited to: staff capacity, reintroduction logistics, management and
conflict minimization materials and activities, depredation compensation, monitoring and research, and
education and outreach. We urge all to remember that conservation and equity take time and
consistent energy and funding.
Proposition 114 asks the General Assembly to ‘make such appropriations as are necessary to fund the
programs authorized and obligations… and… may adopt such other legislation as will facilitate the
implementation of the restoration of gray wolves to Colorado.’
The SAG is concerned that the ongoing costs of the wolf restoration and management program have not
been fully anticipated by the fiscal note supporting CRS 33-2-105.8 in SB21-105, and that funding to
address these costs has not been fully identified. Growth in future annual funding needs should be
anticipated due to growth in the wolf management program.
The SAG recommends that opportunities for private donations be actively marketed through a
communications campaign; that a full list of potential public and private funding sources that can be
used for wolf restoration and management, along with their restrictions, be documented and
maintained; and that funding sources that cannot be used for wolf restoration and management also be
clearly communicated.
To support and sustain a successful wolf restoration and management plan that maximizes positive
benefits and minimizes and mitigates negative impacts, the SAG urges full funding for the program.
Specifically, the SAG recommends:
1. Annual Appropriations. Until such time as a sustainable funding model is established, the SAG
suggests that full funding be provided by the Colorado State Legislature; this number would be
estimated annually by CPW based on wolf-related needs. A preliminary estimate would be an
amount of up to $3 million annually for funding of directly related expenses. This number could

1
Wolf Plan Appendix C-88

�potentially be more when considering adjacent expenses that are indirectly or partially related
to wolf restoration and management, for example research and communications.
2. Wolf Cash Fund or Wolf-Specific Account. To provide long-term, sustainable funding, the SAG
suggests exploration of the use of an existing cash fund, the creation of a new wolf restoration
and management cash fund, or the creation of a wolf-specific account. Annual appropriations do
not guarantee multi-year, long-term funding; establishment or leveraging of an existing cash
fund or other wolf-specific account early in and/or prior to wolf reintroduction can help to
secure public and private funding while interest is high, so that it can be available when needed
in both the short- and long-term. The SAG suggests that this fund or account be provided initial
seed funding by the Colorado State Legislature, and then be supported by a variety of public and
private funding sources. Marketing of opportunities for private donations should be conducted
through a communications campaign. CPW may consider opportunities for the fund or account
to support both holistic, unrestricted funding needs as well as separate, program-specific needs
for compensation and nonlethal conflict minimization. Any cash fund or account should not
compromise CPW’s enterprise status.
3. External Endowment Fund. To enhance opportunities to identify and fundraise from external
sources, the SAG encourages support for the development of an external endowment that is
managed and administered separately, but with input and partnership from Colorado Parks and
Wildlife. The endowment fund would specifically support nonlethal aspects of wolf
management, as well as other programs to explore and develop the projected positive economic
benefits that can come with the restoration of a keystone wildlife species. The specific terms
and governance of the endowment will need to be determined, including whether and how the
fund provides supplemental funding to CPW and/or external entities for nonlethal wolf
management and conflict minimization activities. Full funding for the agency’s annual budget
and programs should be provided directly to the agency through public funding and should not
be reliant on the external endowment. Opportunities for private donations would be actively
marketed through a communications campaign. SAG members are interested to support next
steps for continued exploration and creation of an endowment.

�VI.

Consensus and Voting
a. Consensus
The SAG shall strive to make decisions based on the consensus of all voting members,
where possible. Where the SAG is able to achieve consensus, its input will receive
priority consideration by CPW.
Consensus is defined as general agreement that is shared by all the people in a group; it
reflects a recommendation, option or idea that all participants can support or abide by,
or, at a minimum, to which they do not object. In other words, consensus is a
recommendation, option or idea that all can live with.
Final assessment of consensus: Level of agreement will be assessed and recorded on
final recommendations, options or ideas. A quorum must be present, as defined above.
When conducting a final assessment of level of agreement on a proposed
recommendation, option or idea, each member will indicate whether they can support
or abide by it, and do not object; if no participants object, then consensus exists and will
be recorded, along with a summary of rationale and perspectives as relevant. If any
participant objects, then there is not consensus, and a vote will be taken.
Informal assessment of consensus: When informally assessing level of agreement during
the course of SAG discussions, the table below may be utilized to assess perspectives on
a draft recommendation, option or idea. As relevant, the group will discuss whether, and
if so how, the recommendation, option or idea could be improved and/or how concerns
could potentially be better addressed. Informal assessment of support for a
recommendation or alternative may be conducted iteratively throughout the process
and will not be recorded.
Consensus exists if ALL participants are at level 1-3:

I enthusiastically support this recommendation, option or idea.
I support this recommendation, option or idea.
I do not fully agree with the decision, however I can abide by or live with this recommendation,
option, or idea; I do not object.
I object to this recommendation, option or idea.
I strongly object to this recommendation, option or idea; I cannot support, live with or abide by
it.

b. Voting
Where consensus does not exist on a final recommendation, option, or idea, a vote shall
be taken and the votes of individual members will be recorded along with a summary of
the rationale for supportive and dissenting views. A quorum must be present, as defined
above. Total vote counts, the votes of individual members, and the summary of rationale
and views will be included in the report of the SAG to CPW.
c. Proxies

�No member shall be permitted to vote by proxy or delegate.
d. Reports
A final assessment of the SAG’s level of support for a recommendation, option, or idea
will be conducted publicly and recorded in a report to CPW. The report will reflect the
recommendations or options considered, level of agreement for each recommendation
or option, and a summary of the rationale for both supportive and dissenting views.
Interim reports on specific topics, options or alternatives may be provided by the SAG to
CPW throughout the process. A final report authored by the facilitator with review by
the SAG will compile interim and final feedback on all topics from the SAG to CPW.
VII.

Meetings and Records
a. Regular Meetings
CPW shall establish a schedule for SAG meetings in consultation with the facilitators. The
SAG shall meet one day a month on average. Additional meetings will be called as
necessary by CPW.
b. Facilitation
The CPW Director will contract facilitators to facilitate the work of the SAG. CPW staff
person(s) will be appointed to coordinate with facilitators in the development of
schedules, agendas, materials, and processes for the SAG.
c. Conduct of Meetings
The facilitator will manage meetings of the SAG in the most informal manner possible.
SAG votes will be conducted formally by roll call of the SAG.
d. Public Meetings
The SAG does not have authority to adopt rules or create policy and is not subject to the
Colorado Open Meetings Law. Nonetheless, to support openness and transparency, all
meetings of the SAG shall be open to public observation in person. Information about
meetings will be provided publicly in advance. SAG members may discuss the work of
the group with each other outside of SAG meetings.

e. Public Comment
Public comment opportunities will be offered at SAG meetings. CPW shall determine
when opportunities for public comment will be offered, and in what format. Public
comment opportunities at in-person meetings will be provided only to in-person
attendees. Public comment opportunities at virtual meetings with no in-person meeting
component will be provided to virtual attendees.
f.

Minutes shall be kept of all SAG meetings and shall include at least names of all SAG
members present, the location of the meeting (physical location or virtual meeting), a
summary of the issues or matters discussed, any public comment received, and the
outcome of any formal votes taken; including the vote of individual SAG members when

and manage gray wolves in Colorado and take the steps necessary to begin
reintroduction of gray wolves by December 31, 2023.
On January 14, 2021, the Commission adopted the Division of Parks and Wildlife’s
(Division’s) “proposed blueprint for public involvement to inform the development of
a Colorado Wolf Restoration and Management Plan.” The blueprint contemplates the
formation of advisory groups and states:
The PWC will convene two groups, in consultation with CPW, to
support the management planning process: a Technical Working
Group (TWG) and a Stakeholder Advisory Group (SAG; described
below). These groups are advisory bodies to the PWC. They are
not decision-making bodies and have no authority on wolf
management policy, research, or operations. Blueprint, p. 2.
The SAG is comprised of 19 individuals “with a broad range of interests in wolves and
wolf management and conservation.” Blueprint, p. 3. The SAG has held numerous

�meetings across the state and has made written recommendations to the Commission
on the social considerations of wolf restoration, including payment of fair
compensation to owners of livestock, wolf hazing, and wolf restoration logistics.
On June 30, 2021, the Division issued the SAG Governance Charter. The Charter
explains the operating principles and responsibilities of SAG members and outlines
procedures for reaching consensus recommendations. SAG meetings are to be
conducted “in the most informal manner possible” and are “open to public
observation in person.” Charter, p. 4.
The Division has recently learned that members of the public are using smart phones
or other electronic devices to make audio or video recordings of SAG proceedings,
specifically group deliberations and discussions. The purpose of this amendment is to
expressly prohibit any person, including CPW staff, Keystone Policy Center staff, and
members of the public from making audio and or video recordings of SAG discussions
inside the meeting room and to prohibit any person from live streaming such
meetings. This amendment does not prohibit still photography, stenography, or any
other form of documenting the proceedings. This amendment only applies to
proceedings in the meeting room and not to gatherings in the lobby or hallway outside
such meeting room.
The SAG’s primary charge – to develop recommendations for the Commission
regarding the social considerations of wolf restoration and management – touches on
controversial and divisive topics. In order to promote candid discussion among SAG
members on such topics, the Division, in consultation with the Chair of the
Commission, has determined it is reasonably necessary to take the action described in
this amendment.
Numerous SAG members have expressed concern that such recordings, if posted on
social media or otherwise widely shared, could lead to undesirable outcomes,
including threats, intimidation, and embarrassment, and otherwise chill participation.
The Commission and Division appreciate the SAG members’ service, particularly that
of the volunteer citizen members of the SAG, and believe such concerns are well
founded.
Division staff shall post the attached notice on the meeting room for all future SAG
meetings and the Colorado Parks and Wildlife website.

�History of Colorado Wolves
Gray wolves historically occupied all portions of the state of Colorado and are considered a native species to the state. The species was
eradicated from Colorado in the mid 1940’s. After the reintroductions of wolves to Yellowstone National Park and central Idaho in the
mid 1990’s, wolves have been periodically confirmed to have traveled into Colorado, but a self-sustaining population has not been
present since the time of eradication.
Background leading up to 2023 restoration effort
On Nov. 3, 2020, Proposition 114 was approved by Colorado voters
and is now codified into state statute at CRS 33-2-105.8. State law directs the Parks and Wildlife Commission (hereafter, Commission) to
“develop a plan to restore and manage gray wolves in Colorado, using
the best scientific data available” and “hold statewide hearings to acquire information to be considered in developing such a plan, including scientific, economic, and social considerations pertaining to such
restoration.” The voter-approved statute required the Commission to
take the steps necessary to begin restoration of gray wolves in Colorado west of the Continental Divide no later than Dec. 31, 2023.
To develop the Wolf Restoration and Management Plan (hereafter,
Plan), CPW worked with the Keystone Policy Center to hold public
meetings, collecting feedback from more than 4,000 individuals. Additionally, CPW appointed two advisory bodies: a Technical Working Group (TWG) and a Stakeholder Advisory Group (SAG). The
Technical Working Group consisted of agency and academic scientists and managers with experience in wolf reintroduction and management, as well as others who provided a variety of perspectives
and scientific and policy expertise toward the development of conservation objectives, management strategies, and damage prevention
and compensation planning. The Stakeholder Advisory Group
(SAG) consisted of wolf advocates, sportspersons, tribal representatives, outfitters, and livestock owners, with some members who represented multiple perspectives, who addressed such issues as when
lethal and non-lethal measures would be appropriate and provided
recommendations to staff as they drafted a wolf reintroduction plan.
The primary goal of the Plan is to identify the steps needed to recover and maintain a viable, self-sustaining wolf population in Colorado while concurrently working to minimize wolf-related conflicts
with domestic animals and people. CPW presented the draft Plan to
the Parks and Wildlife Commission on December 9, 2022. CPW and
the Commission then held a series of public meetings where the
public voiced their concerns and support with materials presented in
the draft Plan. Those were discussed by the Commission who recommended edits.

The Final Colorado Wolf Restoration and Management Plan
(available at: https://cpw.state.co.us/Documents/Wolves/2023-FinalCO-Wolf-Plan.pdf) was approved by the Parks and Wildlife Commission on May 3, 2023, through a unanimous 11-0 vote. The Plan
was the culmination of two-and-a-half years of extensive statewide
stakeholder meetings and public outreach to develop a science-based
approach that incorporated the biological needs of the gray wolf and
the social concerns of Colorado’s citizens.
The Plan sets recovery benchmarks for removing gray wolves
from the state Endangered and Threatened species list. The recovery
goals in the Colorado Wolf Restoration and Management Plan are
not directly relevant to federal recovery goals.

Legal Status of Gray Wolves in
Colorado
Federal
Throughout Colorado, wolves are federally listed as an Endangered Species, under the Endangered Species Act (ESA) for which
the USFWS has management authority. As a federally listed species,
take is prohibited. Take, as defined under the ESA, means "to harass,
harm, pursue, hunt, shoot, wound, kill, trap, capture, or collect, or to
attempt to engage in any such conduct.” A nonessential, experimental status has been established for the wolf population in Colorado
under Section 10(j) of the ESA. This status relaxes some of the take
prohibitions and allows opportunistic hazing; non-injurious, intentional hazing; lethal removal for wolves “in the act” of attacking livestock; and in situations where livestock depredation has been
deemed ‘chronic’ and it has been determined that an agency directed
control action is appropriate.
There are no Federal Recovery goals for gray wolves in Colorado.
State
Gray wolves are listed as State Endangered under CPW regulations (#1002 A.1.)). Wolves are classified as a nongame species
(#1004. A. 6.).
The Wolf Restoration and Management Plan describes state
downlisting and delisting goals. To be downlisted from State Endangered to State Threatened, there must be a minimum count of 50
wolves (see Monitoring section below) for a period of 4 years. To be
delisted from State Threatened to State delisted, nongame status,
there must be a minimum count of 150 wolves for a period of 2
years, or 200 wolves, with no time constraint.
There is currently no population objective (maximum desired
population size) for wolves in Colorado.

�Restoration of Wolves

The restoration of wolves is a multi-year effort, with intentions to
release 10-15 wolves per year for 3-5 years. Releases will occur in locations west of the Continental Divide, with a 60-mile buffer from
Tribal lands to the south, and the northern and western borders of
the state. 2023-2024 was the first year of reintroductions of wolves to
Colorado. Upon the completion of this 3-5 year effort, CPW will
continue to monitor the wolf population and will supplement the
restoration effort with additional releases if necessary.
The restoration of wolves in 2023-2024 was conducted in three
separate but related phases - capture, translocation, and release. Each
of these phases are described below.

Capture
The winter of 2023-2024 was the first year of the implementation
of the restoration of wolves to the state. An agreement was made between Colorado Parks and Wildlife and the Oregon Department of
Fish and Wildlife (ODFW) to transfer up to 10 wolves from Oregon
to Colorado.
The capture effort began on December 17, 2023 (Table 1). Five
wolves were captured on the first day, and were released in Colorado
on December 18th, 2023. Four additional wolves were captured December 18 and 19, and the 10th wolf was captured on December 21,
2023. This wolf was released in Colorado on December 22, 2023,
marking the end of the capture and translocation efforts of wolves
for the 2023-2024 winter.

The wolves were transported in aluminum crates, unsedated,
and all wolves handled the trip without incident.

�Translocation
Nine of the 10 wolves that were transported to Colorado for the
purposes of restoration were done using private aircraft. A volunteer
private pilot donated the use of their airplane via the organization
LightHawk Conservation Flying to transport 9 wolves in 3 separate
shipments (5 wolves on 12/18/23, 2 wolves on 12/19/2023, and 2
wolves on 12/20/23). The last animal transported to Colorado was
done via vehicle as this was most logistically feasible.
All wolves were transported in aluminum crates (40.5”L x 27.5”W
x 34”H), unsedated, and all wolves handled the trip without incident.
Release
Within Colorado, release locations were constrained by several
geographic criteria. State statute requires that wolves be released only
west of the Continental Divide (CRS 33-2-105.8). Further, CPW
buffered neighboring states and tribal lands by 60 miles so that reintroduced wolves would not immediately travel out of Colorado. State
and private lands were considered as potential release areas. Only
state lands were used for the release sites in 2023-2024.
Immediately upon arrival at the airport, crated wolves were transported to vehicles for delivery to the release site. Three separate release sites were used to reintroduce wolves. All releases occurred on
state lands, and per state statute, west of the Continental Divide. Release timeline and release counties are described in Table 1, above.

Population Monitoring
There were 12 known wolves in Colorado at the end of the calendar year 2023 (Figure 1 &amp; Table 2). Wolf population counts are done
at the end of the calendar year when biologists can distinguish between adult and juvenile wolves, and wolves are often traveling together in packs. The 12 wolves include the 10 wolves that were
translocated from Oregon in December 2023. Two additional wolves
persisted in Colorado in 2023 from natural colonization and reproduction.

12

Minimum Number of Known Wolves

Upon capture, wolves were assessed for candidacy for translocation. To be considered for translocation, wolves had to be 1-5 years
old (no pups were candidates for translocation); not be breeding
males or females (per request of source state); had to have at least 3
functional canine teeth; had to have both eyes present, functional,
and in good condition; had to have a body condition of fair or better;
had to not have any fractures or missing limbs; had to have no evidence of mange or lice infestation; had to have no severe injury or
injury that was untreatable with on-site care at capture; had to not be
from a currently chronically depredating pack; and had to have a
negative heartworm test. None of the wolves that were captured were
deemed to be unsuitable for translocation.
At the time of capture, each wolf was fitted with a GPS/VHF collar, which continues to be used to monitor the released wolves.
Wolves were captured in Oregon using a helicopter and a spotter
plane. Thirteen CPW staff traveled to Oregon to participate in the
capture effort. Additionally, there were two ODFW biologists, the
helicopter pilot and gunner, the fixed-wing spotter plane pilot and
spotter biologist, totaling 19 individuals who carried out the capture
operation.

have been in that watershed more months. A watershed is a geographic unit that drains water into a specific waterbody at a HUC
10 scale
here. For more information: https://water.usgs.gov/GIS/huc.html
Survival and Reproduction
There were no recognized wolf packs in Colorado in 2023-2024.
Wolf packs will only be recognized after a breeding pair of wolves reproduce (see Glossary). Translocated wolves associated with both
their translocated packmates and other translocated wolves for varying amounts of time. Translocated wolves are also associated with
wolves already in Colorado.
Survival was 100% for known wolves in the state of Colorado in
the 2023-2024 biological year, with no known wolf mortalities. As
stated in the Plan, survival rate for translocated wolves of less than
70% over 6 months would initiate a translocation protocol review.
There was no known wolf reproduction in the state of Colorado in
2023-2024.
Wolf-Prey Relationships
There was no formal examination of wolf predation on wild ungulates in Colorado in 2023-2024. CPW biologists opportunistically
investigated wolf predation events.
There are several High Intensity Elk/Deer Monitoring Areas
which overlapped where wolves were present in 2023-2024. In these
Monitoring Areas, elk and mule deer were outfitted with GPS collars
to monitor survival, cause-specific mortality, and other aspects of
ungulate ecology. These programs will continue in future years.
4

Management

Where wolves and livestock share the landscape, there will be conflict. CPW has developed protocols to investigate and address this
conflict both proactively and retroactively.
Conflict Minimization
Upon District Wildlife Managers (DWM) receipt of a notification
from a livestock producer that there is a need or a desire for conflict
minimization tools, the DWM will contact the Wolf Conflict Coordinator. A site assessment is conducted in conjunction with the Wolf
Conflict Coordinator, DWM, and the landowner, evaluating the materials needed and the scale of impact. A timeline is developed and,
if appropriate, materials are deployed. A total of 24 requests were
made during the 2023-2024 reporting period (Table 3).
Conflict minimization materials are deployed based on the following prioritization scale;
• Proximity of livestock to wolves (localizing vs traveling).
• History of depredation associated with the pack of wolves.
• If the requester has had a confirmed depredation.
• Willingness of the landowner to implement AND maintain
deployed tools.
At the end of the reporting period, CPW had 15 miles of fladry, 85

Colorado Parks and Wildlife collaborated with the Brainerd Foundation, People and Carnivores,
the wolf specialists at Montana Fish, Wildlife &amp; Parks, and the Wildlife Conservation Society to
co-brand a hands-on resource guide that is meant to be a useful introduction for ranchers and
livestock owners to implement effective strategies to prevent wolf depredations.

This illustration from the resource guide highlights some of the risk-management tools that may be appropriate for use
depending on the livestock producer's operation. There are many resources available to further help them identify and implement
the most appropriate strategies to reduce indirect impacts or loss. Producers may consider contacting their local wildlife manager
to learn more about additional resources to assist with cost-share programs, equipment and list of suppliers.

Summary of projects/tools deployed
Between April 1, 2023, and March 31, 2024, 7.25 Miles of fladry
were deployed for 5 locations. This encompassed 7 projects (4 producers) in Jackson County. An estimated average of 200 pairs of cattle were protected for the five locations for a duration of 45-73 days.
For the 5 locations where fladry was deployed during the 2023 calving season, no livestock were lost to wolf depredation while the
fladry was deployed.
Non-lethal tools were deployed as requested, as described in Table 3.

owned materials that may be deployed in collaboration with CPW
included 6 Miles of fladry, 30 foxlights, 60 trail cameras. It is anticipated that these materials will accumulate in the coming years.

�Livestock Depredation Background
When a livestock owner reported suspected wolf-caused depredation(s) to CPW, a CPW representative would meet the livestock
owner at the place where the damage occurred to conduct an on-site
inspection and field necropsy. Claim paperwork would be provided
to the livestock owner (regardless of CPW's determination), and the
claim process was explained by investigating CPW staff. After the investigation was completed (time can vary based on the situation),
the claim would be recommended for approval or denial based on
available evidence documented at the scene. The claimant bore the
burden to prove, by a preponderance of evidence, that damage to
livestock was caused by wolves, for which the state was liable. Please
see the Wolf Restoration and Management Plan and CPW Regulations for details on the Compensation Program.
Summary of Investigations and Compensation
In the 2023-2024 reporting period, CPW staff confirmed 3 wolf depredations (3 sheep), in 1 separate incident. The claimant was paid
$489.00, for a total of $489.00 dispersed in this reporting period
(Table 4).

Table 5. Take permits requested, denied and issued, 2023-2024.

Take Permits
Wolves are federally protected as an Endangered Species under
the Endangered Species Act, so ‘take’ of individuals can only occur
under specific circumstances as defined in the 10(j) rule (Table 5).
See also the Wolf Restoration and Management Plan, Chapter 5,
Wolf Management.
Intentional harassment, deliberate and pre-planned harassment of
wolves, including by less-than-lethal munitions that are designed to
cause physical discomfort and temporary physical injury but not
death, must be permitted via an "Injurious Non-Lethal Hazing” permit. This permit provides specific methods that may be used to haze
wolves (bean bags, rubber buckshot, and/or double balls). Specific
direction on how to deploy these methods and where to aim are provided in the permit. Permittees are required to inform CPW within
72 hours of striking a wolf with any of these methods under the permit. These permits are valid for 1 year.
Take of wolves in the act of attacking livestock or working dogs
must be permitted by a retroactive “In the Act Of ” permit. Attacking
livestock or working dogs includes the actual biting, wounding,
grasping, or killing of livestock or working dogs or chasing, molesting, or harassing by wolves that would indicate to a reasonable person that such biting, wounding, grasping, or killing of livestock or
working dogs is likely to occur at any moment.
CPW received requests to lethally remove depredating wolves,
first by a North Park producer and a second request from the North
Park Stockgrowers Association. This situation was not deemed to be
chronic by CPW and USFWS, in consultation with one another.
Therefore, it would not be appropriate for a landowner to request a
Chronic Depredation permit. CPW did not consider issuing permits
to address Chronic Depredation that would allow a landowner to lethally remove a wolf not in the act of attacking livestock. When a situation is deemed chronic, Chronic Depredation permits to
landowners will only be issued when agency resources are not able
to address the situation directly.

Disclaimer: Research results will not be reported until peer-review
and publication has been completed. See publication list. Please refer
to the CPW Mammals Research Annual Report for additional project information and preliminary research results: Wildlife research
report - mammals. Colorado Parks and Wildlife, Fort Collins, Colorado, USA (https://cpw.state.co.us/Documents/Research/Mammals/
Publications/2023-Wildlife-research-report-Mammals.pdf).
Several biological and ecological research projects related to
wolves in Colorado are underway, primarily in the pilot or testing
stages. CPW’s goal is to refine aspects of these projects over the next
few years in order to develop and deploy rigorous long-term research projects. More details will be shared about these projects in
the near future. Biological and ecological research topics were determined based on public interest, information needed for wildlife conservation, and CPW staff and Commission input.
Biological and ecological research topics include:
• Elk movement, space use, and aggregation patterns in and
out of hunting seasons and with exposure to wolf predation
risk in North Park, Colorado
• Moose recruitment in North Park, Colorado
• Indirect effects of predators on livestock in northwest Colorado
• Wolf social dynamics and space use following translocation
to Colorado
CPW has several social science/human dimensions research projects related to wolves, the largest of which assessed the social outcomes associated with wolf restoration and the public involvement

process in Colorado. This study examined perspectives of various
segments of the population including members of the stakeholder
advisory group (SAG), other interested stakeholders, and members
of the public using a combination of qualitative (interviews) and
quantitative (surveys) methods.
Current human dimensions research topics include:
• History, science, and social values influencing gray wolf recovery in Colorado
• Social trust, social conflict, and social learning
• Wolf management acceptability
• Assessing stakeholder perspectives about engagement process
criteria and evaluation outcomes
CPW is collaborating with partners at Colorado State University,
Colorado State University Extension, and livestock producers. Funding sources for this research come from the National Science Foundation, Colorado General Fund, Rocky Mountain Elk Foundation,
and Colorado State University.

�Agency Collaboration

CPW and the Colorado Department of Agriculture (CDA) entered into a Memorandum of Understanding (MOU) to coordinate
and collaborate in assisting agricultural producers in reducing livestock-predator conflict in concert with each other’s statutory and
regulatory roles and responsibilities. This focuses on the advancement of the adoption of non-lethal management tools, handling
public and media relations, and providing training.
CPW has partnered with the US Department of Agriculture, National Wildlife Research Center to conduct genetic analyses of materials related to wolf genomics.

Education, Outreach and
Media Responses

The CPW Gray Wolf Reintroduction email newsletter (https://
mailchi.mp/state/gray-wolf-reintroduction-enews-edition?e=122f9567de) was launched in March 2021. CPW has issued
32 email newsletters in the reporting period, all archived and listed
on CPW’s Wolves in Colorado webpage. The newsletter has more
than 5,330 subscribers. The goal of these monthly email newsletters
is to provide subscribers with the latest information and news about
wolves in Colorado, including available educational resources, wolf
movement updates, wolf biology facts, and more. The subscriber
number continues to grow as we promote the eNews via press re-

leases, social media, and Colorado Outdoors Online blogs. The average click rate for eNews was 43%, which is considered high for an
email newsletter.
To support public awareness and understanding of the wolf reintroduction work, the CPW Education Section developed a set of resources available for internal and external use. Field staff were
provided with presentations geared towards public and school/youth
requests. These presentations included in-person and virtual training opportunities for staff before use. CPW Regional, and some Area
offices, have also been supplied with wolf biofact kits to use with
these presentations. These biofact kits include a pelt, track plates,
replica skulls, teeth and scat.
For the public, a series of 4 educational videos covering content
including the history, reintroduction process, basic biology, and living with wolves on the landscape were developed. A standards-aligned lesson plan on wolves that can be used by field staff or
teachers in the classroom environment was also developed. These
materials are available on the CPW website and have been presented
through workshops to educators and others.
Media Response
CPW prepared numerous press releases during the reporting period, which are archived at this link(https://cpw.state.co.us/aboutus/
Pages/NewsReleases.aspx). Media response occurred at the local, regional, state, national, and international levels. Social media was active on various channels, including Facebook, X (Twitter),
Instagram, Youtube, and Vimeo.
The latest information about wolves
has been released through a variety
of mediums including (clockwise from
below): YouTube, Instagram, the Gray Wolf
Reintroduction eNews, press releases and
brochures.

Appendix

Glossary
Biological Year - April 1, 2023 -March 31, 2024. The 2023-2024
Annual Report covers this period. Activities that have occurred since
April 1, 2024 will be incorporated into the annual report covering
the 2024-2025 Biological year.
Breeding pair/male/female - The dominant pair, male, or female
that breeds in a wolf pack. The term “alpha” has fallen out of favor.
Group - Wolves that consistently travel together without documented reproduction.
Pack - A pack is made up of the breeding wolves and their offspring from that and previous years. Non related and more distantly
related wolves may also be members of a pack. A group of wolves
will only be named as a pack after documented reproduction.
Wolf ID - Each collared wolf is given an unique identifier. This 4
number code indicates the year that the animal was initially captured,
and the consecutive order in which it was captured. For the last 2 digits, an odd number indicates that the animal is male; an even number
indicates that the animal is female. Therefore 2301, was the first male
captured in 2023. 2302 would be the first female captured in 2023.

How to Report a
Wolf Sighting in Colorado
Colorado Parks and Wildlife Managers have many tools to help monitor wolves in Colorado, such as GPS and radio collars, signs of tracks, hair and scat, and wolf sightings from
the public. Your information will help CPW monitor this species.
Have you seen a wolf?
Help Colorado Parks and Wildlife biologists monitor
wolves by filling out the Wolf Sighting Form. Whenever possible, please provide a photo or video, the exact
location coordinates, and other detailed information
for confirmation purposes. Your identity and the location of the sighting are protected by CPW and will not
be publicly shared.

How to identify a gray wolf
Gray wolves are about twice the size of coyotes. They
can measure up to 6 feet in length, including tail, and
stand approximately 30 inches in height at the shoulder. For more information, see the handout Coyote or
gray wolf: How to spot the differences.

Living With
Wolves

© JERRY NEAL/CPW

HOW TO AVOID WILDLIFE CONFLICTS

cpw.state.co.us
cpw.state.co.us

�What to Do if You Live in
Wolf Country

Generally, wolves are calm and elusive. Wolves are
habitat generalists, but are most commonly found in
areas with plentiful deer and elk populations. Wolves
avoid humans and are unlikely to approach people or
homes.

What to Do if You
Encounter a Wolf

Aggressive behavior from wild wolves toward
humans is very rare. Encounters with wolves are an
interaction—you should follow these guidelines and
assess how the wolf responds to your action so you
can choose what to do next. Each situation is unique.

We can live with these native predators if we respect
gray wolves and their habitat. To reduce the risk of
problems with wolves on or near your property, we
urge you to follow these simple precautions.

Do not approach a wolf, especially one
that is feeding or with pups, or if you have
a dog with you. Most wolves will try to
avoid a confrontation. Give them a way to
escape.

It is very rare for wolves to cause a direct
threat to humans.

Maintain visual contact with the wolf so
you can see what it is doing and where it
is. Talk calmly yet firmly to it and make
enough eye contact so that it knows you
have seen it. Most wolves will run away.

☐ Make lots of noise if you come and go during the
times when wolves are most active—dusk to dawn.
☐ Don’t feed wolves or any other wildlife.
☐ Keep pets close to your home at all times of
day, and bring them in at night. Don’t feed pets
outside. Store all garbage securely.
☐ Place livestock in enclosed sheds or barns at night
when available/appropriate. Close doors to all
outbuildings so wildlife cannot get inside.
☐ Please see CPW's Wolf Resource Guide
cpw.info/Wolf-Resource-Guide
(cpw.info/Wolf-Resource-Guide) for more
information about protecting livestock.

Recreating in Wolf Country
To reduce the likelihood of an encounter, or of an
encounter turning into an attack, general alertness of
surroundings is highly recommended.
Look around — scan the sides of hills,
forests or open meadows.
▶ Make noise so you don’t surprise wildlife.
▶ Hike with a sturdy walking stick or bear spray.
▶ Keep pet dogs on a leash or close to you with voice
control at all times.

If you have a dog with you, keep the dog
away from the wolf. Dogs can aggravate
wolves, and the situation can escalate if
dogs are acting aggressively toward wolves.
If there is shelter or a vehicle nearby, face
the wolf and stand upright while backing
away slowly. Running may stimulate a
predatory instinct to chase and attack.
If you cannot retreat, stand your ground,
face the wolf and try to appear larger. For
example, raise your arms, stand on a
stump or a rock or open your jacket. Place
obstacles you may have, like a bike,
between you and the wolf.
If the wolf behaves more aggressively (eyes
locked on you, ears forward or
backwards), yell loudly, clap and wave
your walking stick in front of you. An air
horn may also be effective.
If the wolf gets even more aggressive (ears
lowered, growling/snarling, baring teeth),
be ready to fight back or deploy bear spray
at an approaching wolf.
In the very unlikely event that a wolf
attacks you, fight back. Remain standing,
and try to get back up if you are knocked
down. A wolf ’s underbelly and face,
including its eyes, can be sensitive areas to
target with fingers or sharp objects if you
have to strike back.

�G

ray wolves are habitat generalists. If you live
or recreate in the foothills or mountains of
Colorado, you are in wolf country. Wolves are not
normally a danger to humans, but you should treat
wolves with the same respect you give any other wild
animal. With a better understanding of wolves and
their habitat, we can coexist with these magnificent
animals.

What We Know About
Wolves

The gray wolf (Canis lupus) historically ranged across
much of the Northern Hemisphere and beyond, from
the Arctic to Mexico and from coast to coast. Once
distributed statewide, the gray wolf was extirpated
from the state in the 1940s. It took nearly 80 years
before wild wolf pups were born again in Colorado,
which occurred in 2021.
CPW’s Wolf Restoration and Management Plan
calls for wolves to be released over 3-5 years (1015 animals per year) into select areas west of the
Continental Divide. Release locations will not occur
within 60 miles of neighboring states so that released
wolves are more likely to remain in Colorado. It is
anticipated that wolves will eventually inhabit many
areas of Colorado, but releases will use this buffer
with the intent of limiting immediate dispersal into
neighboring states. Wolves are also likely to disperse
to areas east of the Continental Divide.

How Big Are Gray Wolves?
GRAY WOLF
Species:

Canis lupus

Present in Colorado?
Adult Weight:

YES

Physical appearance
The gray wolf is the largest of the
wild canids. Wolves look like large
dogs and their coloring ranges
from black to pale gray. Wolves
occasionally are more tawny colored
or even white.
Gray wolves are about twice the size
of coyotes. They can measure up to
six feet in total length, including tail,
and stand approximately 30 inches
in height at the shoulder. Female
wolves weigh around 80-90 pounds,
while males weigh around 90-110
pounds.
The gray wolf has a long bushy tail
and erect, slightly rounded ears. Its
legs are longer, feet larger and chest
narrower than a dog of similar size.
Wolves have larger and blockier
snouts/muzzles and shorter and
more rounded ears than coyotes,
who have longer, narrower features.
Wolves also have distinctively
bushier and shorter tails.
Tracks
Depending on the substrate, wolf
tracks are about 5 inches long by 4
inches wide, with four symmetrical
toes and identifiable claws; coyote
tracks are similar, but are only
about half that size. Large dogs,
such as livestock guardian dogs,
can have tracks with similar
dimensions to wolves.

�Habitat

Mating and breeding

Wolves may be found anywhere in Colorado, but are
predominantly likely to be found in regions where elk
and deer are abundant. Wolf habitat includes riparian
areas, mountains, forests and open meadows. Wolves
generally avoid steep and rocky terrain and areas of
human activity.

A wolf ’s natural life span is about six years in the
wild. Wolves are sexually mature at two years old, but
may not breed until they are older. In each pack, the
behaviorally dominant male and female are usually
the breeders, and they prevent subordinate adults
from mating by physically harassing them. Breeding
occurs in February, and gestation is approximately
nine weeks. In April, breeding females produce a litter
of four to six pups, on average; typically only one litter
is produced per pack per year. Wolves generally den
in underground burrows that the breeding female
digs out. The breeding male and other packmates
provide food for the nursing mother.

Wolves are very territorial, meaning they protect
the area where they hunt and raise young from
wolves that are not in their pack. Wolves define their
territory by scent marking, urinating and defecating.
The size of the territory depends on the terrain,
how much food is available and proximity to other
wolf packs. Wolves also communicate through
vocalizations and may let another pack know they are
in the area by howling.
Hunting and feeding
Wolves are most active from dusk to dawn, although
they do travel and hunt in daylight. Wolves prefer
to eat ungulates like deer, elk and moose; however
they also eat other small mammals and, occasionally,
livestock. In Colorado, elk will likely make up the
majority of wolves’ diets.
Wolves are cursorial hunters, meaning they chase
their prey to capture them. Members of the same
pack hunt together, and larger packs are better at
killing large prey. The vast majority of wolf hunts are
unsuccessful, and hunting is dangerous to the wolf.
Injuries acquired during hunting are a leading cause
of natural mortality for wolves, such as being kicked
or gored.
Habits
Wolves are social animals, living in a family group
known as a pack. A pack usually consists of 6-10
animals: a male and female (the breeding pair), pups
from the previous year (yearlings) and the current
year’s pups. Wolves disperse from the pack they
were born in around age 2 or 3. Wolves that do not
disperse may remain in the pack as subordinate
adults, and occasionally, an unrelated adult will join
the pack. The dominant pair tends to lead the pack by
raising the young, selecting denning and rendezvous
sites, and maintaining the territory. The territory
may cover 20-120 square miles. The size of their
territory depends on factors like suitable habitat, food
availability and wolf density. Wolves naturally require
a lot of space, which can sometimes lead to conflict
with humans.

At six weeks old, the pups are weaned and the adults
begin to bring them meat. Adults eat the meat at a
kill site, then return and regurgitate the food for the
pups to eat. The hungry pups jump and nip at the
adults’ muzzle to stimulate regurgitation. The pack
leaves the den when the pups are 6-12 weeks old. The
female carries the pups in her mouth to a rendezvous
site or nursery area. The rendezvous site is the focus
of the pack’s social activities for the summer months
and is usually near water. By August, the pups wander
up to 2 to 3 miles from the rendezvous site and use
it less often. The pack leaves the site in September or
October and the pups, now mobile, follow the adults.

Report a sighting

CPW receives and investigates many potential wolf
sightings each year.
We have a wolf sighting form available on our website
and we encourage you to fill it out if you believe you
have seen a wolf in your area.
We ask that any photos or videos be included with
these reports if available.

�Introduction and Thanks

The CPW Commission has passed regulations that
align with US Fish and Wildlife Service guidelines
and provide landowners with a wide variety of options
and resources to minimize conflict and potential wolf
depredation. This includes commonly accepted hazing
techniques such as fladry (fencing), range riders, guard
animals, and scare devices.
Specific regulations are subject to change through
approvals from the CPW Commission; the most recent
regulations can be found in https://cpw.state.co.us/
Documents/RulesRegs/Regulations/Ch10.pdf.
Livestock owners concerned about wolves on their
property should contact their local CPW office to

work closely with our district wildlife managers on
implementing the strategies listed in this guide.
Running livestock in wolf range is challenging. Costeffective risk management can increase profitability.
While there is no silver bullet, there are some proven
techniques for reducing risk of wolf-livestock conflict.

Guard
Animals

The goal of this brochure is to outline different tools
that may suit your operation. Your local wildlife agency
or other organizations can offer additional help in
evaluating and identifying options and may offer cost
sharing, materials, or labor to assist your efforts.
Colorado Parks and Wildlife would like to thank
Brainerd Foundation, People and Carnivores, Montana
Fish, Wildlife and Parks wolf specialists, and the
Wildlife Conservation Society for providing CPW
with permission to co-brand this useful document in
Colorado.

�Management Intensive Grazing

Management Intensive Grazing
(MIG): Also known as mob grazing,
uses higher stocking densities with
frequent pasture changes.
Where It Works Best:
Any size pasture
Cattle, sheep, goats, and horses

Livestock Guarding Dogs

Considerations:
• Close proximity of cattle may increase risk of
disease depending on the time of year MiG is used
and the age of livestock.
• MiG takes advantage of stock’s natural response to
predators. Stock naturally bunch up in response to
predators, making them less vulnerable, and can
reduce issues of weight loss.
• Steep terrain may make MiG challenging.

Livestock Guarding Dogs (LGD) are
specially bred and reared dogs that
bond to and watch over livestock.
They watch for potential threats and
use escalating aggression to move
wolves away.
Where It Works Best:
Up to 1,000-acre pastures
Sheep, goats, horses, and cattle

When It Works:
Yearlong: typically late spring through fall

When It Works:
Yearlong

Advantages:
• Periodic herd management increases human
presence, which may discourage wolves from
frequenting pastures and aid in early detection of
wolves.
• Prompt doctoring of sick or injured stock
minimizes high-risk animals.
• Frequent pasture changes make the location of
livestock less predictable for wolves.
• MiG practices beneﬁt range health.

Advantages:
• Dogs travel with the livestock.
• Dogs provide around-the-clock vigilance.
• Dogs’ scent marking and barking behaviors signal
an occupied territory to wolves.
• Dogs alert people to trouble

Disadvantages:
• MiG requires more labor.
• May require building and moving temporary
electric fence.

COLORADO PARKS &amp; WILDLIFE • Wolves: Hands-on Resource Guide to Reduce Depredations

Considerations:
It is mportant to match the right breed of Livestock
Guard Dogs (LGD) with your ranch needs:
• There are over 30 breeds of livestock guard dogs.
The right number and breed of LGDs for your
ranch will depend on the size of operation and wolf
activity.
• There are two diﬀerent behaviors
• Roamers: LGD breeds that tend to be more
oriented toward driving predators away. A good
example of these breeds include: Anatolian,
Komondor, Turkish Kangal, and Akbash.
• Tenders: LGD breeds that tend to stick closer to
livestock and even attempt to gather up stock
when confronted with threats. A good example
of these breeds include: Tatra, Maremma, and
Pyrenees.
• Select your LGD for intellect instead of aggression
• Evaluate and assess how the dogs are working
to make adjustments (# of dogs, behavior, breed)
when needed. When dogs are in close proximity
to wolf dens or homesites there is the potential for
wolves to view LGD as territorial intruders. During
these times, consider keeping LGD and livestock in
alternate pastures or increase vigilance of riders.
• Use at least 3 dogs. Larger groups increase the dogs’
safety and have greater potential to deter wolves.
• Dogs should be socialized to people for ease of vet
care, moving dogs, and encounters with public.
• Provide dogs with protective collars to reduce
mortality in wolf conﬂicts.
• Introduce dogs before conﬂicts arise so they can
learn their landscape and establish presence.
• When used in smaller pastures, you may need to
train LGD to electric fences to discourage roaming
onto roads or near non-tolerant neighbors.

Disadvantages
• Dogs are not as eﬀective with highly dispersed
livestock.
• Dogs can be viewed as a competitor especially in
wolf territories and can be vulnerable to attack.
• Dogs require additional expenses of food and vet
care.

�Livestock Guarding Donkeys

Donkeys watch over livestock,
look for potential threats and use
escalating aggression to move
predators away.
Where It Works Best:
Up to 1,000 acre pastures
Sheep, goats, horses, and cattle
When It Works:
Yearlong
Advantages:
• Travel with the livestock.
• Provide around the clock vigilance.
• No extra feeding needed, forage with livestock.
• Low cost, minor maintenance.
• Provide an alert presence.
• Not prone to wandering.
• Long life expectancy.
Disadvantages:
• Too many donkeys in one pasture may lead to
congregating only with each other rather than
displaying protective behaviors.
• Are not as eﬀective in larger dispersed herds.
Considerations:
• Consider Jennies rather than Jacks.
• Use larger donkey breeds (eg., mammoth donkeys).
• Introduce young donkeys for at least 1-2 weeks to
allow bonding with livestock.
• Donkeys can be aggressive toward dogs, so initially
limit and supervise their interaction with ranch
dogs. Dogs will learn to work around donkeys.
6

Carcass Management

Range Riders and Herders

Removing or disposing of
attractants (carcasses) that may
lure wolves into close proximity of
livestock.
Where It Works Best:
Any size pasture
All livestock including poultry
When It Works:
Yearlong, typically spring and fall when death loss is
greatest.
Advantages:
• Reduces potential conﬂicts by minimizing attractants.
• Most ranches already spend time moving carcasses
to a deadpile; the same amount of time can be
devoted to staging carcasses for removal by a local
contractor to either a carcass composting facility or a
landﬁll that accepts carcasses.
Disadvantages:
• Burying carcasses can be diﬃcult in freezing ground.
Considerations:
• Consider burying or burning carcasses regularly.
• Reduce access to carcasses or carcass pits with woven
wire, electric fence, ﬂadry, or a combination of these
tools.
• Community level carcass pickup programs with
central disposal or composting sites have proven
successful.
• Terrain, road access, or deep snow may make
removal diﬃcult.

COLORADO PARKS &amp; WILDLIFE • Wolves: Hands-on Resource Guide to Reduce Depredations

Range riders and herders manage
herd and range health, herd
distribution, and help in early
detection of carnivore-livestock
interactions.
Where It Works Best:
640 acres or greater for cattle, sheep and goats
When It Works:
Yearlong
Advantages:
• Allows for earlier detection and management of
injured, sick, or dead livestock.
• Provides proactive management of livestock
distribution in relation to range health as well as
carnivore presence.
• Human presence and non-lethal harassment
deters wolves.
• Improves information exchange on predator
activity between the livestock producer and
managing agencies.
• Allows producer to know when preventative
eﬀorts need to be stepped up.

Disadvantages:
• Limited mobility of a single rider.
Considerations:
• Using riders and herders to reduce conﬂicts can
be even more eﬀective if used in conjunction with
other tools, especially livestock guard dogs and
management intensive grazing.
• Herders live with livestock and range riders spend
periods of time with livestock.
• Depending on scale, a rider can cover a number of
ranches and even a watershed.
• Range rider eﬀectiveness depends on allotment
size, terrain, and distribution and visibility of
livestock on the range.

�Fladry/Electrified Fladry

Scare Devices
• Areas with high wind may require more
maintenance due to ﬂags entangling with
vegetation or wrapping around wire.

Fladry (flagging interspersed on a
single strand of twine) is a portable
barrier strung around livestock
pastures or holding areas. The
flagging triggers an innate fear and
avoidance in wolves because it is
a novel stimulus. By electrifying
the fladry, a wolf’s fear response is
reinforced with an electric shock.

Considerations:
• Fladry equipment has limited availability,
conservation groups and wildlife agencies may
have supplies available for loan.
• Electriﬁcation of ﬂadry is not as eﬀective in dry
ground areas but including an earth-return-wire
(AKA groundwire) can resolve this issue.
• Needs vigilance to keep it maintained and
working properly. Wolves eventually habitate
to ﬂadry, so it should be moved or electriﬁed to
reduce or prevent habituation.
• Ideal for smaller pastures (calving pastures, horse
pastures, sheep night pens, and protecting deadpits).

Where It Works Best:
Any size pasture, typically with enclosures &lt; 640 acres
(1 mile per side)
All livestock, including poultry
When It Works:
Yearlong
Advantages:
• Fladry requires relatively small quantities of
materials.
• Easily transported, laid out, and erected.
• Requires less planning than a permanent fence.
• Can be stored when not needed.
• Can be reused.
• Especially advantageous when moving livestock
frequently and supplies/labor are limited.
Disadvantages:
• May require extra maintenance in heavy snow
areas or areas of heavy vegetation growth (as this
may result in grounding issues).

COLORADO PARKS &amp; WILDLIFE • Wolves: Hands-on Resource Guide to Reduce Depredations

• Scare devices may not be welcomed in areas of
high human presence.
• May be difficult to obtain due to federal
regulations on (pyrotechnics), limited suppliers or
manufacturers.
Considerations:
• Ideal for short duration in areas of frequent wolf
use.
• Ideal when used in addition to other tools.
• Varying the scare devices can increase
eﬀectiveness.
• RAG boxes require radio collars and only work if
a radio-collared wolf is present.
• MAG boxes may be more appropriate as they are
not aﬀected by steep rocky terrain like RAG boxes
are. MAG boxes can be triggered by any motion.

Scare devices like motion or radio
activated (MAG/RAG) boxes,
sirens, strobe lights, pyrotechnics,
scarecrows, and radios change wolf
behavior by causing fear.
Where It Works Best:
Small pastures/pens (&lt;60 acres) or areas with frequent
wolf use for short durations (2-3 months)
When It Works:
Yearlong
All livestock, including poultry
Advantages:
• Certain scare devices (sirens, lights, MAG/RAG
boxes) can alert people to the presence of an
animal as well as scare animals away.
• Relatively low cost.
• Simple and portable tool.
• Can be used to discourage wolves from placing
dens or homesites near livestock.
Disadvantages:
• Wolves may habituate and quickly learn to ignore
the device.

�High-risk Landscape Management

Risk of wolf/livestock encounters
can be reduced by understanding
and adjusting ranching practices
during times and areas of high risk.
Typically these are areas of high
prey abundance (elk calving and
wintering ground) and wolf activity
(dens).

Herd Composition
Considerations:
• Evening/dusk feeding should start 2 weeks prior
to encourage day calving when predators are less
active.
• Plan calving to correspond with wild ungulate
birth pulse (May-June), thus livestock are not
the only vulnerable or high-risk prey on the
landscape.
• To increase herd security, utilize high stocking
rates for short duration (more Animal Days/Acre)
in pastures with good forage in high use wolf
travel paths.
• Delay turnout to pastures when wolves are
denning or at homesites in or near pastures.
• Consider pastures with low ungulate activity
and/or encourage hunting or hazing (check
regulations) to disperse localized ungulates.
• Bring into corrals or barn at night.
• Night pen in an electric fence.

Where It Works Best:
Any size pasture
Cattle, sheep, goats, and horses
When It Works:
Yearlong: typically in seasons of high ungulate
densities or wolf use.
Advantages:
• Lowers risk of depredation and vulnerability of
livestock by avoiding high-risk landscapes.
• Maintains use of forage and pastures in high-risk
areas by altering the timing of use.
Disadvantages:
• Potentially more labor intensive.
• Requires changes to husbandry practices.

COLORADO PARKS &amp; WILDLIFE • Wolves: Hands-on Resource Guide to Reduce Depredations

Mixing different age classes
and breeds of livestock reduces
vulnerability to predation.
Where It Works Best:
Any size pasture
Sheep, cattle, goat, horses, and mules
When It Works:
Yearlong
Advantages:
• Stronger maternal instincts may reduce
vulnerability of young.
• Experienced animals are less likely to ﬂee and more
likely to stand their ground, making them diﬃcult
for wolves to attack.
• Experienced animals may avoid areas of high
predator presence and inﬂuence other stock to do
the same.

• Handling younger animals may be more diﬃcult
with protective mothers.
• Classes and breeds may self-segregate, operating as
independent herds within in the same pasture.
Considerations:
• Mix experienced older age classes with (younger)
naïve livestock.
• Add a few aggressive or vigilant breeds to your
herd.
• Retain and promote livestock with stronger
maternal instincts.
• It is riskier to run yearlings or naïve livestock.

Disadvantages:
• Retaining older, experienced stock primarily for
protective purposes may impact proﬁtability.
• Sorting diﬀerent classes or breeds for shipping/
marketing may be an additive chore/cost.
• Horned cattle have associated risks to handlers and
dogs.
