Description: Developed to support the Bureau of Land Management (BLM) / U.S. Forest Service (USFS) Greater Sage-Grouse (GRSG) Monitoring Framework, the Biophysical Settings Sagebrush Base data layer is a binary raster comprised of pixels representing 28 ecological systems which were determined to have the capability of supporting sagebrush vegetation while also providing suitable seasonal habitat for GRSG. Sagebrush vegetation was defined as sagebrush species or subspecies that provide habitat for GRSG and are also included in the Sage-Grouse Habitat Assessment Framework (Stiver et al., 2014). The resultant data layer was derived from the U.S. Geological Survey (USGS) LANDFIRE Version 1.2 Biophysical Settings (BpS) vegetation data product (http://www.landfire.gov). BpS represents the natural plant communities that may have been dominant on the landscape prior to Euro-American settlement, and is determined by both the current biophysical environment and an approximation of the historical disturbance regime. BpS is composed of vegetation map units based upon NatureServe’s terrestrial ecological systems classification, which is a nationally consistent set of mid-scale ecological units (Comer et al., 2003).
