In the past, the Grizzlies lived on the vast territories from Alaska to Texas and Mexico.
There is a perception that the decline of the grizzly population began during the Spanish colonization of the Americas. With the advent of Europeans and the growth of large-scale settlements, the usual habitat of the grizzly began to steadily decline. For Indians the bear was a totem animal and played an important role in the mythology of many tribes. However, even they were hunting grizzly, using its meat for food, skin for clothing, and claws and teeth as ornaments. For immigrants from Europe, the bear has become a competitor in the extraction of food and was a potential threat to life that led to his mass killings.
Currently, the largest population of grizzly bear inhabits Yellowstone national Park. The total population is currently estimated at 50 000 individuals
