The selection of geological basins from the 1995 National Oil and Gas Assessment Province Boundaries that (1) intersected with the historical Sage-grouse geographic range, and (2) contained significant oil and/or natural gas reserves according to the U.S. Geological Central Energy Team. Data defining (1) can be found at: http://sagemap.wr.usgs.gov/ftp/regional/wdfw/sagerange.zip and (2) can be found at: http://certmapper.cr.usgs.gov/data/noga95/natl/spatial/shape/pr_natlg.zip. The present data layer was selected from (2) and reprojected to match the Albers projection used in the Rangewide Conservation Assessment.
