    dct:description """This tabular data set represents the estimated area of level 3 ecological landscape regions (ecoregions), 
as defined by Omernik (1987), compiled for every MRB_E2RF1 catchment of the Major River Basins 
(MRBs, Crawford and others, 2006). The source data set is Level III Ecoregions of the Continental 
United States (U.S. Environmental Protection Agency, 2003).
		
The MRB_E2RF1 catchments are based on a modified version of the U.S. Environmental Protection 
Agency's (USEPA) ERF1_2 and include enhancements to support national and regional-scale 
surface-water quality modeling (Nolan and others, 2002; Brakebill and others, 2011).
		
Data were compiled for every MRB_E2RF1 catchment for the conterminous United States covering 
New England and Mid-Atlantic (MRB1), South Atlantic-Gulf and Tennessee (MRB2), the Great Lakes, 
Ohio, Upper Mississippi, and Souris-Red-Rainy (MRB3), the Missouri (MRB4), the Lower Mississippi, 
Arkansas-White-Red, and Texas-Gulf (MRB5), the Rio Grande, Colorado, and the Great basin (MRB6), 
the Pacific Northwest (MRB7) river basins, and California (MRB8).""" ;
