Grizzly bears (Ursus arctos horribilis) are found in North America, primarily in the western regions of the United States and Canada. They inhabit a variety of ecosystems, including forests, mountains, subalpine meadows, and coastal regions. Here are the main areas where grizzly bears are found:
United States:
- Greater Yellowstone Ecosystem: This region includes parts of Wyoming, Montana, and Idaho. It is home to one of the largest populations of grizzly bears in the lower 48 states.
- Northern Continental Divide Ecosystem: This ecosystem spans parts of Montana and Idaho. It is known for its rugged mountains and dense forests, providing suitable habitat for grizzly bears.
- Selkirk Mountains: Located in Idaho and Washington state, the Selkirk Mountains are home to a significant grizzly bear population.
- Cabinet-Yaak Ecosystem: This ecosystem includes parts of Montana and Idaho. It is characterized by mountainous terrain and dense forests, offering important habitat for grizzly bears.
Canada:
- British Columbia: British Columbia has the largest population of grizzly bears in Canada. They are found in various regions, including the Great Bear Rainforest, the Kootenay Mountains, and the Cariboo Mountains.
- Alberta: Grizzly bears are present in western Alberta, particularly in the Rocky Mountains and foothills.
- Yukon Territory: The Yukon Territory is home to a sizable population of grizzly bears, found in diverse habitats ranging from forests to alpine tundra.
- Northwest Territories: Grizzly bears are found in parts of the Northwest Territories, including the Mackenzie Mountains and the Dehcho Region.
It is important to note that grizzly bear populations are not uniformly distributed within these regions. Some areas may have higher densities of grizzly bears due to factors such as habitat quality, food availability, and human activities. Conservation efforts are in place to protect grizzly bears and their habitats across North America.
