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…

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…

Loss and degradation of sagebrush habitat throughout western North America has led to growing concern for conservation of greater sage-grouse (Centrocercus urophasianus) and repeated petitions to list the species under the Endangered Species Act.…

Large-scale changes to sagebrush habitats throughout western North America have led to growing concern for conservation of greater sage-grouse (Centrocercus urophasianus) and repeated petitions to list the species under the Endangered Species Act.…

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…

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…

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…

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…

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.…

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…
