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 of "Current Range" - The current sage-grouse
distribution is the range believed to be occupied in the late 1990's,
based on the best information available.
