The Endangered Species Act has classified the grizzly bear as a threatened species in the continental United States. However in 2007 the bears were removed from the list at Yellowstone National Park. Other reserves where the bears reside include locations in Alaska, Montana, Idaho, Washington, and Wyoming.
The grizzly bear (Ursus arctos ssp.) is any North American subspecies of brown bear, including the mainland grizzly (Ursus arctos horribilis), Kodiak bear (U. a. middendorffi), peninsular grizzly (U. a. gyas), and the recently extinct California grizzly (U. a. californicus â ) and Mexican grizzly bear (U. a.nelsoni â ).n other words, the grizzly and the brown bear are one species on two continents. Currently, Rausch and others classify three subspecies of the new North American brown bear: U. a. horribilis, middendorffi, and gyas.
