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.
