The purpose of the NGB rapid ecoregional assessment is to demonstrate and document a large- (regional-) scale rapid spatial assessment of potential change in selected resource values as a result of certain change agents. Specifically, the focus of the assessment is on the current extent of sagebrush, juniper, and salt desert shrub; sagebrush-juniper interface; location of greater sage-grouse habitat; location of mule deer winter range; location of large wildfires; and extent of cheatgrass (and potential for cheatgrass to expand). The assessment identifies geographicspecific priority areas in the region and enables land managers to develop local management strategies and associated actions designed to ameliorate impacts from the identified change agents on the specified resource values.--Page 1.
