Summary
Abstract: 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 coverage is intended for national-level studies of water resources.

Reviews_Applied_to_Data. The Ecoregions were plotted on a terminal to ensure
the EXPORT file was imported properly. No claims are made regarding the
accuracy of the original data or linework.

Quality The Ecoregions were plotted on a terminal to ensure the EXPORT file
was imported properly. No claims are made regarding the accuracy of
the original data or linework.

This coverage was imported from an ArcInfo Export (.e00) file supplied
by EPA Corvallis. Some item names were modified and others were
redefined to make the coverage more convenient to use, and to conform
to more conventional item names.
