As worldwide threats to biodiversity increase and extinction rates rise to 1000 times the natural background extinction rate, the conservation of biological diversity is emerging as a major public policy issue. The report examines the response of natural systems to stressors, the factors which determine the vulnerability of species, and the ultimate and proximate causes currently depleting biological diversity in the United States. Included is an overview of the effects of 13 stressors on 59 categories of organisms in the contiguous United States.
