Description:

Abstract:

This map layer is commonly called Bailey's ecoregions and shows
ecosystems of regional extent in the United States, Puerto Rico, and the
U.S. Virgin Islands.  Four levels of detail are included to show a
hierarchy of ecosystems.  The largest ecosystems are domains, which are
groups of related climates and which are differentiated based on
precipitation and temperature.  Divisions represent the climates within
domains and are differentiated based on precipitation levels and patterns
as well as temperature.  Divisions are subdivided into provinces, which
are differentiated based on vegetation or other natural land covers.  The
finest level of detail is described by subregions, called sections, which
are subdivisions of provinces based on terrain features.  Also identified
are mountainous areas that exhibit different ecological zones based on
elevation.

Purpose:

These data are intended for geographic display and analysis at the national level, and for large regional areas. The data should be displayed and analyzed at scales appropriate for 1:7,500,000-scale data. No responsibility is assumed by the National Atlas of the United States in the use of these data.

Supplemental_Information:

The same data are available from both the National Atlas of the United
States and from the USDA Forest Service Inventory and Monitoring
Institute.

Detailed descriptions of the domains, divisions, and provinces represented
in this map layer are available at:
http://www.fs.fed.us/institute/ecoregions/ecoreg1_home.html.  Detailed
descriptions of the sections represented in this map layer are available

Process_Description:

The USDA Forest Service ecoregions shapefile for the 48 conterminous
States and the export file for Alaska were downloaded and reprojected to
a Lambert Azimuthal Equal Area projection using Arc/INFO.  The
shorelines were removed and replaced with shorelines from the National
Atlas States map layer.  Linework was cleaned and adjusted.  USDS Forest
Service ecoregions attribution for Hawaii, Puerto Rico, and the U.S.
Virgin Islands was added to the polygons for those areas defined by the
National Atlas shorelines.

The polygon attribution was checked and the following corrections were
made: For Ecocode = -263A the Province field was blank; this was
corrected to California Coastal Steppe-Mixed Forest-Redwood Forest
Province.  For Ecocode = M242A, Ecocode = M242B, and Ecocode = M242C
the Division was corrected from Marine Regime Mountains Redwood Forest
Province to Marine Regime Mountains.

Attribute_Definition:

A subdivision of a division.  A province represents variations in
vegetation or other natural land covers within a division.  Mountainous
areas that exhibit different ecological zones based on elevation
(elevational zonation) are distinguished according to the character of
