Endangered and Threatened Wildlife and Plants; Grizzly Bear Listing on the List of Endangered and Threatened Wildlife With a Revised Section 4(d) Rule

요약

We, the U.S. Fish and Wildlife Service (Service or FWS), propose to revise the listing of the grizzly bear (Ursus arctos horribilis) in the lower-48 States under the Endangered Species Act of 1973, as amended (Act or ESA). After a review of the best scientific and commercial data available, we affirm that the currently listed grizzly bear population meets our requirements for consideration as a distinct population segment (DPS) under the Act and that the population remains likely to become an endangered species within the foreseeable future. However, we find that clarification of the geographic areas included within the DPS is warranted. Therefore, we propose to revise the listing by defining the boundaries of the contiguous U.S. grizzly bear DPS. The revised entity would include all geographic portions of the currently listed lower-48 entity that contain suitable habitat and where grizzly bears are currently found or are likely to be found in the future as populations recover. This area includes all of Washington and portions of Idaho, Montana, and Wyoming. The contiguous U.S. grizzly bear DPS would retain threatened species status. This proposed rule would promote conservation of
