The Colorado Division of Wildlife (CDOW) proposes to conduct a study of the Parachute/Piceance/Roan (PPR) population of greater sage-grouse during 2007 and 2008. The PPR is one of several small, spatially fragmented populations of sage-grouse in Colorado. The CDOW is interested in working with energy companies and other land owners and managers in the PPR area to sustain the PPR grouse population and plan for future management actions. The objectives of the study are to obtain current, baseline information on the genetic characteristics; measures of reproduction and survival rates; and patterns of habitat use and seasonal movements of sage-grouse in this population.

Sage grouse (Centrocercus urophasianus) populations throughout North America have declined by at least 30% since the 1980's. Such declines have corresponded with habitat degradation caused by both natural and anthropogenic perturbations to sagebrush (Artemisia spp.) landscapes. Several populations now occur in highly fragmented and isolated habitats throughout Colorado. Future management of sage grouse will require knowledge of the seasonal requirements in fragmented landscapes. The primary goal of this study was to evaluate the ecological requirements of a small, naturally fragmented sage grouse population in northwestern Colorado. The topography of this region naturally fragmented the sagebrush habitats, thus affecting movements and habitat use. I analyzed sage grouse spatial distribution and seasonal movements (Chapter 2) to identify how this heterogeneous landscape may affect dispersion and migration. I also analyzed habitat use as it varied from the landscape to foraging site scale (Chapter 3). Radiotelemetry was used to identify movement and habitat use patterns. I provided management recommendations for this isolated population (Chapter 4) as an adaptive resource management framework, to progressively test habitat manipulations and enhancement projects.

Isolated populations of the Gunnison sage grouse (Centrocercus minimus) in fragmented habitats were studied from 1994 through 1996 to examine seasonal habitat use and movements near Dove Creek, Dolores County; Dry Creek Basin/Miramonte Reservoir, San Miguel County; and Green Mountain/Fruitland Mesa, Montrose County, Colorado. Use of sagebrush habitats near Dove Creek was less ($P 0.05$) than expected based on availability except from December through February. Agricultural fields (alfalfa, beans, wheat) predominated in Dolores County and were used throughout summer. Sagebrush (Artemisia tridentata) and sagebrush mixed with Gambel oak (Quercus grambelli) were used in fall and winter. Habitat use did not differ ($P 0.05$) from availability at Dry Creek Basin, but did differ ($P

Admired for its elaborate breeding displays and treasured as a game bird, the Greater Sage-Grouse is a charismatic symbol of the broad open spaces in western North America. Unfortunately these birds have declined across much of their range—which stretches across 11 western states and reaches into Canada—mostly due to loss of critical sagebrush habitat. Today the Greater Sage-Grouse is at the center of a complex conservation challenge. This multifaceted volume, an important foundation for developing conservation strategies and actions, provides a comprehensive synthesis of scientific information on the biology and ecology of the Greater Sage-Grouse. Bringing together the experience of thirty-eight researchers, it describes the bird’s population trends, its sagebrush habitat, and potential limitations to conservation, including the effects of rangeland fire, climate change, invasive plants, disease, and land uses such as energy development, grazing, and agriculture.
