Ecological Subregions: Sections and Subsections for the Conterminous United States
vector digital data
Washington, DC
USDA - Forest Service
The Soil Section feature class contains ecological section polygons attributed with soil characteristics to show relationships between ECOMAP 2007 and soil data from STATSGO, 2005. The EcomapSections 2007 data set describes the ecological sections within the conterminous United States. It contains regional geographic delineations for analysis of ecological relationships across ecological units. ECOMAP is the term used for a USDA Forest Service initiative to map ecological units and encourage their use in ecosystem-based approaches to forest land conservation and management. This is a collaborative effort with many partners. It is coordinated at the national and regional levels by USDA Forest Service staff and implemented in cooperation with State forestry agencies and others. ECOMAP mapping criteria are outlined in the National Hierarchical Framework of Ecological Units (https://www.ncrs.fs.fed.us/gla/reports/hierarchy.htm). The framework systematically divides the country into progressively smaller areas of land and water that have similar physical and biological characteristics and ecological processes.
The purpose of the Ecomap Sections and Subsections data sets is to provide a baseline map of the ecological boundaries. The data can be used for ecological analysis of resource distribution patterns and associations among different ecological land units.
