Estimated potential for sage-grouse movement among sage-grouse leks (Circuitscape; McRae 2006). Rescaled HSI values were used as a measure of landscape resistance
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...

Habitat similarity index (HSI) values for greater sage-grouse across their western range. HSI values represent the relationship of environmental values at map locations to themultivariate model of minimum requirements for sage-grouse deļ¬ned by land cover, anthropogenic variables, soil, topography, and climate.

This data set represents a preliminary attempt to define distinct areas of Sage-grouse occupation in North America. The 'boundaries' for subpopulations are not actually boundaries, but lines meant to encircle a specific group of leks. The difference may seem trivial, but it is significant. We did not establish an area associated with each population or subpopulation, and consequently we did not evaluate the associated habitat and/or landscape. This type of analysis would have required a specific assessment of the habitat within and between each of the identified populations and subpopulations. The descriptions of subpopulations are clearly a preliminary attempt to define distinct areas of occupation.
