SUMMARY: The best available scientific and commercial data indicate that the Greater Yellowstone Ecosystem (GYE) population of grizzly bears (Ursus arctos horribilis) has recovered and no longer meets the definition of an endangered or threatened species under the Endangered Species Act, as amended (Act). The United States Fish and Wildlife Service (Service) is also proposing to identify the GYE grizzly bear population as a distinct population segment (DPS). Therefore, we, the Service propose to revise the List of Endangered and Threatened Wildlife, under the authority of the Act, by removing the GYE population. The Service has determined that the GYE grizzly bear population has increased in size and more than tripled its occupied range since being listed as threatened under the Act in 1975 and that threats to the population are sufficiently minimized. The participating States of Idaho, Montana, and Wyoming must adopt the necessary post- delisting management objectives, which adequately ensure that the GYE population of grizzly bears remains recovered, into enforceable regulations before the Service will proceed with a final delisting rule.<<<Read More>>>
