This metadata references the polygonal ARC/INFO GIS cover showing the current and historic distribution of potential habitat, or range, of the Greater Sage-grouse (Centrocercus urophasianus) and Gunnison Sage-grouse (Centrocercus minimus) in Western North America. This data was initially researched and compiled by Dr. Michael A. Schroeder, research biologist for the Washington State Department of Fish and Wildlife. The initial draft of current and historic range data was mapped and submitted to state, federal, or provincial natural resource agencies and other experts for review, comment, and editing. The final product represents the best available science and expert review available at the time of compilation.Definition...

This map depicts regions within the range of the Greater Sage-grouse that are non-Sage-grouse habitat. This information was complied using coverage of sagebrush for the western United States and a coverage of grassland habitats within 5km of an active Sage-grouse lek. This map has a 540m resolution.

This map depicts the distribution of sagebrush and associated shrubsteppe habitat types using readily available data from a variety of source maps from WA, OR, CA, UT, NV, CO, WY, MT, ND, SD, AZ, NM, AB, and BC. Habitat was grouped from map sources that were classified with detailed information on specific sagebrush types, as well as coarse-scale maps that classified vegetation as only "shrub" in the case of ND and the Canadian provinces. This map is a 90-meter grid, but source material included 30 to 90-meter grids, and 1:24,000 and 1:100,000 polygon coverages.

This map depicts the proportion of non-Sage-grouse habitat with 18km of each pixel. The map was produced using a moving window analysis on the Distribution of Non-Sage Grouse Habitat in the Conservation Assessment Area with a search radius of 18km. The product of the moving window was the mean pixel value within the window. This map has a 540m resolution.

This map depicts the proportion of non-Sage-grouse habitat with 54km of each pixel. The map was produced using a moving window analysis on the Distribution of Non-Sage Grouse Habitat in the Conservation Assessment Area with a search radius of 54km. The product of the moving window was the mean pixel value within the window. This map has a 540m resolution.
