HEADWATERS ECONOMICS GEOGRAPHIC DATA LIBRARY DOCUMENTATION TITLE: Geodataset Name: NAmer_Sagebrush Geodataset Type: SHAPE Geodataset Feature: POLYGON GENERAL DESCRIPTION: This dataset describes the distribution of Sagebrush and Associated Shrub-steppe Habitats in Western North America. DATA SOURCE(S): USGS, Snake River Field Station Scale of Original Source Maps: 1:24,000 and 1:100,000 Date of Original Source Maps: 2004 GEODATASET EXTENT: Western North America FEATURE ATTRIBUTE TABLES CODES AND VALUES: NA DATA LINEAGE SUMMARY: The dataset was provided by CommEn Space and was orginally created by Cara Meinke, USGS-FRESC Snake River Field. This map depicts the distribution of sagebrush and associated shrubsteppe habitat types using readily available data from a variety of source maps from WA, OR, CA, UT, NV, CO, WY, MT, ND, SD, AZ, NM, AB, and BC. Habitat was grouped from map sources that were classified with detailed information on specific sagebrush types, as well as coarse-scale maps that classified vegetation as only "shrub" in the case of ND and the Canadian provinces.
