Abstract

Preliminary descriptions are presented for the 190 section ecological units delineated on the U.S. Department of Agriculture Forest Service 2007 map “Ecological Subregions: Sections and Subsections of the Conterminous United States.” Brief descriptions of the section map units provide an abstract primarily of the climate, physiography, and geologic substrate that combine to form ecosystems with distinctive vegetation and other unique ecological characteristics. Many descriptions are illustrated with a photograph of the landform and vegetation found in the section.
