Description:
Ecoregions of the SARP region based on Omernik (1987) attributed to NHDplus catchments.  Ecoregions are areas with generally similar ecosystems and similar types, qualities, and quantities of environmental resources,.  Ecoregion boundaries were determined by examining patterns of vegetation, animal life, geology, soils, water quality, climate, and human land use, as well as other living and non-living ecosystem components. Level III ecoregions are delineated for regional analysis and decision-making.
