Grizzly bears are now found wild only in Canada and Alaska and in parks and reserves in Montana, Idaho, Wyoming and Washington. Largest American population is in Yellowstone National Park. They were once widespread throughout North America, and even as far south as Mexico but they were wiped out by hunting and habitat disturbance. It has been listed as an endangered species since 1975 and is now protected. There are probably still 50,000 grizzlies living in Canada and Alaska, with another 1,000 or so in the USA. But there were at least ten times this number two hundred years ago.
