GRIZZLY BEAR
Ursus arctos horribilis
Habitat- Grizzly bears are found in many different habitats, from dense forests to subalpine meadows, open plains and arctic tundra. In North America, grizzly bears are found in western Canada, Alaska, Wyoming, Montana, Idaho and a potentially a small population in Washington. Historically, they could be found from Alaska to Mexico and from California to Ohio. The grizzly bear was once common on the Great Plains. However, human encroachment has forced the remaining brown bear populations to move to rugged mountains and remote forests that are undisturbed by humans.
Population- Historically, there were around 50,000 grizzly bears in North America. Today, there are an estimated 1,800 grizzly bears remaining in five populations in the lower 48 states. Most of these bears are located in the Northern Continental Divide Population (including Glacier National Park) and the Yellowstone Population. Alaska is home to a healthy grizzly (sometimes called brown bear) population.
Diet- Grizzly bears are omnivores, and their diet can vary widely. They may eat …show more content…
Grizzly bears feed on ungulates primarily as winter-killed and wolf-killed carrion but also through predation on elk calves (Gunther and Renkin 1990, Mattson 1997). Some large male grizzly bears also prey on adult bison during early spring. Grizzly bears also dig up pocket gopher caches in localized areas where they are abundant. Other items consumed during spring include succulent grasses and sedges during early green-up, dandelion, clover, spring-beauty, horsetail, and ants. During spring, grizzly bears will also feed on whitebark pine seeds stored in red squirrel caches during years when there is an abundance of over-wintered seeds left over from the previous fall (Mattson and Jonkel
