Geometry Type: esriGeometryPolygon

Description: The Ecomap 2025 contains a feature class for five different levels of the National Hierarchical Framework of Ecological Units (the Hierarchy. FSM 2060): Ecological Domains, Ecological Divisions, Ecological Provinces, Ecological Sections, and Ecological Subsections. The Ecomap 2025 data set describes the ecological hierarchy within the conterminous United States. Each feature class contains polygons attributed with the code and name of the ecological unit along with the codes and names of broader scale units into which a given ecological unit is nested. 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 and range 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 (Cleland et al. 1997, FSM 2060). The framework systematically divides the country into progressively smaller areas that have similar geophysical and biological characteristics and ecological processes.
