Land-use Conflicts with Natural Vegetation in the United States

Abstract
There exists no current inventory of how much of the United States is occupied by natural vegetation, nor how much area is covered by particular plant communities. In this study, the potential existing vegetation-cover of the United States was determined by using a computer algorithm that was developed to subtract extant landuse data from the potential natural vegetation. This was done on a county-by-county basis for the 48 conterminous States.
