Evaluation of alternative population monitoring strategies for greater sage-grouse (Centrocercus urophasianus) in the Parachute-Piceance-Roan population of northwestern Colorado
Robust estimates of population size and population trends provide the scientific basis for managers to make appropriate and defensible recommendations regarding land-use decisions, harvest regulations, and mitigation efforts for wildlife. When linked…
Evaluating lek-based monitoring and management strategies for greater sage-grouse in the Parachute-Piceance-Roan population 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 populations has increased range-wide and in Colorado due to population…
Columbian sharp-tailed grouse demographic response to habitat improvements
The Columbian sharp-tailed grouse (CSTG, Tympanuchus phasianellus columbianus) is one of 6 subspecies of sharp-tailed grouse in North America. Historically its distribution ranged from the northwest in British Columbia to the southwest in Colorado.…
Avian response to plague management on Colorado prairie dog colonies
Range-wide declines in prairie dog (Cynomys sp.) populations have occurred, and the largest limiting factor in recent decades appears to be the high mortality and colony extirpation associated with plague (Antolin et al. 2002), caused by the…
Assessment of greater sage-grouse response to pinyon-juniper removal in the Parachute-Piceance-Roan population of northwestern Colorado
Greater sage-grouse (Centrocercus urophasianus) in the Parachute-Piceance-Roan (PPR) region of western Colorado face at least two major potential stressors: projected habitat loss from energy development and a long-term decline in habitat suitability…
Official state watercraft inspection and decontamination (WID) protocols and procedures
Aquatic nuisance species (ANS) or aquatic invasive species (AIS) are also called non-native species, exotic species, non-indigenous species, noxious weeds, or pests. ANS can be plants or animals. Invasive aquatic plants are introduced plants that…
Official Colorado watercraft inspection and decontamination procedures: trainer’s workbook: certification curriculum for authorized agents
The purpose of this workbook is to provide consistent guidance to State of Colorado Aquatic Nuisance Species (ANS) Trainers who are responsible for certification of individuals as Authorized Agents for the purpose of ANS Watercraft Inspection and…
Boat compendium for aquatic nuisance species (ANS) inspectors
The purpose of this compendium is to provide guidance to certified boat inspectors and decontaminators on various watercraft often used for recreational boating in Colorado. This book is not inclusive of all boats that inspectors may encounter, but…
Brown-capped rosy-finch population assessment pilot study
The Brown-capped Rosy-Finch (BCRF; Leucosticte australis) is a small, hardy passerine that resides in high elevation alpine environments throughout the year. It has the smallest range of the three closely related species of Rosy-Finch (L. atrata, L.…
American pika (Ochotona princeps) 2015 monitoring survey
Concern about American pika (Ochotona princeps, pika) populations stemmed from limited research linking climate change to population extirpations in the Great Basin and Sierra Nevada Mountains (Beever et al. 2003, Moritz 2007). In October 2007, the…
