Endangered and Threatened Wildlife and Plants; Review of 2017 Final Rule, Greater Yellowstone Ecosystem Grizzly Bears

We, the U.S. Fish and Wildlife Service (Service), announce our determination that our 2017 final rule to designate the population of grizzly bears in the Greater Yellowstone Ecosystem (GYE) as a distinct population segment and remove that population from the Endangered Species Act's List of Endangered and Threatened Wildlife does not require modification. After considering the best scientific and commercial data available and public comments on this issue received during a regulatory review, we affirm our decision that the GYE population of grizzly bears is recovered and should remain delisted under the Act. Accordingly, the Service does not plan to initiate further regulatory action for the GYE grizzly bear population.
