Aquatic ecoregions of the conterminous United States

Metadata Updated: September 18, 2024

Ecoregions are based on perceived patterns of a combination of causal and integrative factors including land use, land surface form, potential natural vegetation, and soils (Omernik, 1987). This is a copy of the ecoregion coverage of Omernik (1987) with some item names modified.
This is NOT the most recent version of the ecoregion definitions, which can be obtained from: Environmental Protection Agency, Western Ecology Division, Corvallis, OR at http://www.epa.gov/wed/pages/ecoregions/level_iii.htm.
