Abstract

The Southern Variant of the Forest Vegetation Simulator utilizes ecological units mapped in 1995 by the Forest Service, U.S. Department of Agriculture, to refine tree growth models for the Southern United States. The 2007 revision of the 1995 map resulted in changes of identification and boundary delineation for some ecoregion units. In this report, we summarize the major differences between the two maps and how the differences affect users of the Southern Variant of the Forest Vegetation Simulator. We also provide a table for converting ecoregions from their identifications on the 2007 map to their former identifications on the 1995 map.
