Abstract:

This shapefile and raster image presents the National Hierarchical Framework of Ecological Units (ECOMAP 1993) by county for the coterminous United States. Assignment of the framework to individual counties is based on the predominant area by province and section to facilitate integration of county-referenced information with areas of uniform ecological potential. Included are maps illustrating county-scaled ecological subregion boundaries by division, province, and section; and numeric codes by Federal Information Processing Standard and USDA Forest Service Resources Planning Act region.

Purpose:

This shapefile is used as a base map for a variety of applications.

Supplemental_Information:

This shapefile is usually referred to as "Bailey's ecoregions" but limited to Southern States excluding the Dry Domain (prairie) ecoregions. The ecoregions included in the shapefile are within the following states: AL, AR, FL, GA, KY, LA, MS, NC, SC, TN,OK, TX, and VA.
