Furthermore, because grizzly bears have babies at a very slow rate, it takes many years for the population to grow.
Most of the grizzly bears in the United States, excluding Alaska,live in Yellowstone and Glacier National Parks.As grizzlies are still protected by the ESA,hunting them is illegal. As bear population grow,it becomes very important to prevent encounters between humans and bears: 20 to 40 bears are killed each year to protect the safety of humans. People living in grizzly bear habitats are encouraged not to leave garbage lying around in case bears are attracted to the smell, and parks put up signs warning people not to stray off the path. Visitors are also warned not to alarm any bears they encounter.
