USFWS proposes to revise the listing of the grizzly bear (Ursus arctos horribilis) in the lower-48 States under the ESA. After a review of the best scientific and commercial data available, they affirm that the currently listed grizzly bear population meets the 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. USFWS 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. Clarifying that the listing does not include areas outside of the grizzly bear's historical range will assist as recovery proceeds. USFWS are also proposing to revise protective regulations for the grizzly bear issued under section 4(d) of the Act. They will accept comments received or postmarked on or before 17 March 2025.
