title: Data from: Dusky grouse seasonal resource selection in the Great Basin isolated mountain ranges of Nevada, USA

description: Dusky Grouse Dendragapus obscurus are a montane forest grouse species with
 a paucity of information regarding their temporal and spatial resource use
 during critical times of high mortality and reproductive output. This lack
 of vital data may leave Dusky Grouse at risk of sub-optimal management in
 many areas of their distribution, especially in the isolated ‘sky island’
 mountain ranges of the Great Basin, where high elevation habitats are
 surrounded by sagebrush and chaparral flats. Many of these high elevation
 habitats are being altered and lost rapidly from increasing disturbance
 events and effects of climate change. Our objective was to evaluate Dusky
 Grouse resource selection in the Schell Creek, Duck Creek, and Egan ranges
 of White Pine County, Nevada during breeding, nesting, brood-rearing, and
 over winter to identify habitats of importance for concentrating
 conservation actions. We found that breeding male Dusky Grouse selected
 for aspen stands, nearness to water, and nearness to forest edges, while
 breeding female Dusky Grouse selected for mountain mahogany, aspen, and
 mountain shrub communities (i.e., sagebrush), and areas with high
 predicted probability of males. Nesting female Dusky Grouse selected for
 mountain shrub communities, intermediate elevation, low ruggedness, and
 high percent shrub cover. Brooding female Dusky Grouse selected for aspen
 and mountain shrub communities, nearness to water, high percent shrub
 cover, and intermediate elevation and ruggedness. Finally, wintering
 female Dusky Grouse selected for spruce-fir and pine conifer types, high
 elevation and ruggedness, and farther distances from forest edges, while
 selecting against high percent tree canopy cover. Our results suggest that
 Dusky Grouse may be a good indicator species of aspen and conifer health
 in the Great Basin mountain ranges. Conservation priority should be placed
 on these limited vegetation types, especially given the slow regeneration
 and growth in the region due to the arid climate and xeric soils.
