USDA - Forest Service ECOMAP Team 20170504 vector digital data GTR WO-76 Washington, DC USDA - Forest Service The data sets used were developed from multi-layer soil characteristics, based on the USDA State Soil Geographic Database (STATSGO). More information about the data sets may be obtained through the Soil Information for Environmental Modeling and Ecosystem Management web page, http://www.soilinfo.psu.edu USDA - Forest Service ECOMAP Team 20170504 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. 20070101 publication date Complete As needed -124.762615 -66.798038 49.386392 24.530689 None porosity soil ecoregion plasticity K factor pH permeability ecomap available water capacity bulk density section ISO 19115 Topic Categories biota geoscientificInformation None United States None The USDA Forest Service makes no warranty, expressed or implied, including the warranties of merchantability and fitness for a particular purpose, nor assumes any legal liability or responsibility for the accuracy, reliability, completeness or utility of these geospatial data, or for the improper or incorrect use of these geospatial data.
