In this 2019 photo provided by the U.S. Fish and Wildlife Service is a grizzly bear (Ursus arctos horribilis) in Grand Teton National Park, Wyoming. Grizzly bears are slowly expanding in the northern Rocky Mountains but scientists say they need continued protections and have concluded no other areas of the country would be suitable for the fearsome animals. The Fish and Wildlife Service on Wednesday, March 31, 2021, released its first assessment in almost a decade on the status of grizzly bears in the contiguous U.S. (Joe Lieb/USFWS via AP)
