Abstract: The discovery of a distinct lineage of Cutthroat Trout in museum specimens collected from the San Juan basin precipitated an intensive search for any remaining extant populations across the putative native range of this fish. Tissue samples…

An electric fish barrier was installed on the east portal of South Canal to reduce fish entrainment associated with the construction of two hydropower plants in 2012. The objective of this study was to monitor fish entrainment and evaluate the…

Gunnison sage-grouse (Centrocercus minimus) have declined substantially from their historica range and were listed as threatened by the U. S. Fish and Wildlife Service in November of 2014. GUSG are distributed into seven isolated populations in…

Rangewide declines of greater sage-grouse and recent energy development within sagebrush habitat has led to concern for conservation of greater sage-grouse (Centrocercus urophasianus) (GRSG) populations across Colorado, including in North Park, which…

State agencies have long used micro-scale vegetation measurements to assess relationships between species and how they chose their habitat. Often species select small scale habitat based on vegetation structure, the height and density of certain…

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…

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…

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…

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…

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…
