This page was last edited on 23 April 2023, at 15:09. Coastal areas host the highest population densities year round because there is a larger variety of food sources available, but Brooks Camp hosts the highest population (100 bears).

Control actions and habitat loss extirpated them from 98 percent of their original habitat in the U.S., including the Great Plains and all habitats south of Yellowstone National Park and Grand Teton National Park in Wyoming, including California, Idaho, and Washington. They frequently prey on baby deer left in the grass, and occasionally they raid the nests of raptors such as bald eagles. Another factor currently being taken into consideration when designing conservation plans for future generations are anthropogenic barriers in the form of urban development and roads. [3], Coastal grizzlies, often referred to by the popular but geographically redundant synonym of "brown bear" or "Alaskan brown bear" are larger and darker than inland grizzlies, which is why they, too, were considered a different species from grizzlies.
