Grizzly bears (Brown bear or Ursus arctos) once inhabited most of the Western United States. They favored areas near streams and rivers, where conflicts with humans were likely. In the beginning of the 20th century, Grizzlies were eliminated from 95% of their range and survived only in remote wilderness areas.
Today, Grizzly bears are found in mountain ranges from the coast of British Columbia to the Rocky Mountains in Alberta. The home range of Grizzlies varies from 200-500 sq. km. for females to 1000-2000 sq. km. for males. Grizzlies need places with minimal human access. Human activities cause constant stress on Grizzly bears and other animals. Grizzly Bears - Description
Males reach their maximum weight in 12 years of age and are 330-1150 pounds. Females are fully grown in 8 years of age and reach 270-770 pounds. So a male Grizzly bear is 1.2 to 2.2 times as heavy as a female Grizzly bear. The largest males have more chances of breeding, and the largest females are more likely to have cubs.
Grizzly bears range in color from white and blonde to brown and black. The tips of fur are lighter in color giving the animals a Grizzled effect. This species has a distinguishing shoulder hump, which is actually a mass of muscle enabling the animal to use their paws more effectively. Grizzly bears have long and curved claws that are used for digging up roots and excavating dens.
