Description:
The Ecoregion data set covers aquatic ecoregions of the conterminous U.S. It is provided by the USGS and is intended for national-level studies of water resources. Aquatic 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 at a map scale of 1:7,500,000. The USGS has requested that they be contacted via email for questions and information.
