White-tailed ptarmigan occupancy report
In 2010, the white-tailed ptarmigan (Lagopus leucura; WTPT) was petitioned to be listed as threatened under the Endangered Species Act. The petitioners cited climate change and its impacts to a species dependent on alpine habitats as the main threat…
WaTSS user manual: water temperature summary software
Water temperature is perhaps the single most important environmental parameter for fish (Magnusen et al. 1979). As ectothermic organisms, ambient temperature drives survival (Dickerson and Vinyard 1999, Bear et al. 2007, Underwood et al. 2012,…
Using GPS satellite transmitters to estimate survival, detectability on leks, lek attendance, inter-lek movements, and breeding season habitat use of male greater sage-grouse in northwestern Colorado
Implementing effective monitoring and mitigation strategies is crucial for conserving populations of sensitive wildlife species. Concern over the status of greater sage-grouse (Centrocercus urophasianus) populations has increased both range-wide and…
Using digital photographs and pattern recognition identify individual boreal toads (Anaxyrus boreas boreas)
Individual identification of animals can provide an array of useful capture-mark-recapture information, allowing researchers to estimate survival, movement, abundance, recruitment, and capture probability (Williams et al. 2002). This information can…
Southern White-tailed Ptarmigan (Lagopus leucura altipetens) Population Assessment and Conservation Considerations in Colorado
Status of the southern white-tailed ptarmigan (Lagopus leucura altipetens) in Colorado was assessed from 2013-2017 using a number of metrics to determine trends in abundance, survival, site fidelity, reproductive success, resource selection, and…
Raptor data integration, species distribution, and suggestions for monitoring
Where they exist, raptor monitoring databases have generated important insights into various aspects of raptor ecology, and can provide a sound foundation for specific management priorities for individual species or within the larger context of…

Pinyon jay breeding colony summary investigation Southwest Colorado 2020
Pinyon jays (Gymnorhinus cyanocephalus) are thought to be declining range-wide (Boone et al. 2018). Very little is known about their breeding status and habitat use in Colorado. In 2020, Colorado Parks and Wildlife examined six breeding colonies in…
Pilot study to evaluate avian response to conservation reserve program mid-contract management practices in northeastern Colorado
The Conservation Reserve Program (CRP) is a government program in which landowners are paid to maintain grass cover on land that was, and would otherwise be, used for row-crop agriculture. Overall, the CRP has had many documented benefits to…
Pilot study to assess northern bobwhite response to short-duration intensive grazing on Tamarack State Wildlife Area
Widespread suppression of historic disturbance regimes have reduced heterogeneity in vegetation communities on which many wildlife rely for various life events and stages. Northern bobwhites require areas of thicker grass cover for nesting within…
