According to the National Wildlife Foundation, there are an estimated 32,500 grizzly bears remaining in the wild in the United States as of 2014. Of these, 31,000 are in Alaska, and the remainder are spread throughout the United States and Canada.
Grizzly bears thrive in many different types of habitats. They live in dense forests, subalpine meadows, open plains and arctic tundra. In the lower 48 United States, they are mainly located in Wyoming, Montana, Idaho and Washington.
Grizzly bears are typically solitary animals, but they are not very territorial. They have been seen feeding together in areas where food is abundant. When the younger bears grow up and leave their mother, they often set up their home range within a close distance of their mother's home range.
