Brown bear <=SEP=> The brown bear ( Ursus arctos ) is a large bear with the widest distribution of any living ursid . The species is distributed across much of northern Eurasia and North America . It is one of the two largest terrestrial carnivorans alive today , rivaled in body size only by its close cousin , the polar bear ( Ursus maritimus ) , which is much less variable in size and averages larger due to this . There are several recognized subspecies , many of which are quite well-known within their native ranges , found in the brown bear species .   The brown bear 's principal range includes parts of Russia , Central Asia , China , Canada , the United States ( mostly Alaska ) , Scandinavia and the Carpathian region ( especially Romania ) , Anatolia , and Caucasus . The brown bear is recognized as a national and state animal in several European countries .   While the brown bear 's range has shrunk and it has faced local extinctions , it remains listed as a least concern species by the International Union for Conservation of Nature ( IUCN ) with a total population of approximately 200,000 . As of 2012 , this and the American black bear are the only bear species not classified as threatened by the IUCN . However , the Californian , North African ( Atlas bear ) , and Mexican subspecies were hunted to extinction in the nineteenth and early twentieth centuries , and many of the southern Asian subspecies are highly endangered . One of the smaller-bodied subspecies , the Himalayan brown bear , is critically endangered , occupying only 2 % of its former range and threatened by uncontrolled poaching for its parts . The Marsican brown bear , one of several currently isolated populations of the main Eurasian brown bear race , in central Italy is believed to have a population of just 30 to 40 bears .

Grizzly bear <=SEP=> The grizzly bear ( Ursus arctos ssp . ) , less commonly known as the silvertip bear , is a large subspecies of brown bear inhabiting North America . Scientists generally do not use the name grizzly bear but call it the North American brown bear .   Multiple morphological forms sometimes recognized as subspecies exist , 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 † ) and Mexican grizzly bear ( U. a. nelsoni † ) . On average bears near the coast tend to be larger while inland Grizzlies tend to be smaller .   The Ussuri brown bear ( U. a. lasiotus ) inhabiting Russia , Northern China , and Korea is sometimes referred to as black grizzly although it is a different subspecies from the bears in America .

Kodiak bear <=SEP=> The Kodiak bear ( Ursus arctos middendorffi ) , also known as the Kodiak brown bear , sometimes the Alaskan brown bear , inhabits the islands of the Kodiak Archipelago in southwest Alaska . Its Alutiiq name is taquka-aq . It is the largest recognized subspecies of brown bear , and one of the two largest bears alive today , the other being the polar bear .   Physiologically , the Kodiak bear is very similar to the other brown bear subspecies , such as the mainland grizzly bear ( Ursus arctos horribilis ) and the now-extinct California grizzly bear ( U. a. californicus † ) , with the main difference being in size . While there is generally much variation in size between brown bears in different areas , most usually weigh between 115 and 360 kg ( 254 and 794 lb ) . The Kodiak bear , on the other hand , commonly reaches sizes of 300 to , and has even been known to exceed weights of 680 kg on occasion . Despite this large variation in size , the diet and lifestyle of the Kodiak bear does not differ greatly from that of other brown bears .   Ever since the first humans arrived in Alaska over the Bering land bridge , encounters between people and Kodiak bears have occurred . Today , these encounters have become relatively more common as a result of the increase in the human population in the region . Such encounters have included the hunting of bears by humans for their fur or meat , and , less commonly , attacks by bears upon humans . More recently , as conservation efforts have become more commonplace , concerns over the sustenance and stability of the Kodiak bear population have arisen . The IUCN classifies Ursus arctos , the species to which the Kodiak belongs , as being of `` least concern '' in terms of endangerment or extinction . However , the IUCN does not differentiate between subspecies ; therefore , it is unknown whether the Kodiak bear population is as healthy as is stated . As a result , the Alaska Department of Fish and Game , along with , to a lesser extent , the United States Fish and Wildlife Service , closely monitors the number of bears hunted in the state .
