The Endangered Species Act and the Distinct Population Segment Policy

The Endangered Species Act and the Distinct Population Segment Policy

The US Fish and Wildlife Service has proposed to delist the Yellowstone grizzly bear (Ursus arctos) as a distinct population segment, pursuant to the 1996 Distinct Population Segment Policy, on grounds that these bears have achieved their recovery goals. In this paper I discuss the Distinct Population Segment Policy and suggest that it does not provide a workable basis for classifying populations for purposes of delisting or down listing decisions, and I review aspects of the Yellowstone grizzly bear delisting decision.
