    Description

    This publication describes the 34 ecosystems into which all the land of the 48 contiguous states has been classified in the Forest-Range Environmental Study (FRES) of the Forest Service, U.S. Department of Agriculture. The description of each ecosystem discusses physiography, climate, vegetation, fauna, soils, and land use. For a number of the ecosystems, the descriptions include discussions of the productivity classes into which these units have been categorized. For each of these ecosystems, the herbage production in each class is given. An index relates the ecosystems to phytocoenoses.
