Terrestrial Ecosystems for the Conterminous United States

Detailed Description
USGS used the same biophysical stratification approach in its first continental project, modeling the distribution of terrestrial ecosystems for the conterminous United States. Four major structural components for ecosystems – isobioclimates, land surface forms, surficial lithology, and topographic moisture potential – were modeled and then spatially combined into a set of biophysical settings to represent the unique ecosystems.
