This map is commonly called Bailey's ecoregions and shows ecosystems of regional extent in the United States, Puerto Rico, and the U.S. Virgin Islands, based on conditions in 1994. 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. Also included are maps of the Bailey Ecoregions of the United States in multiple formats and sizes.

Also included are maps of the Bailey Ecoregions of the United States in multiple formats and sizes.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.Data were originally published on 02/23/2016. Minor metadata updates were made on 07/21/2016 and 12/19/2016. On 12/03/2019, the metadata was updated to include links to this National Geospatial Data Asset (NGDA) which was also available as a map service. Effective 03/12/2021, these data were no longer considered an NGDA so the link to the map service was removed on 03/22/2024 along with a few other minor metadata updates.
