Relocation of the bear has been used to separate the bear from the human environment, but it does not address the problem of the bear's newly learned association of humans with food or the environmental situations which created the human-habituated bear. [199] Brown bears seem to confront humans as they would when fighting other bears: they rise up on their hind legs, and attempt to "disarm" their victims by biting and holding on to the lower jaw to avoid being bitten in turn. However, they have been recorded as inhabiting every variety of northern temperate forest known to occur. Habituated or food-conditioned bears can also be dangerous, as their long-term exposure to humans causes them to lose their natural shyness and, in some cases, to associate humans with food.

The more important of the carnivores which haunt the forests, valleys and mountain slopes are the bear (Ursus arctos), wolf, lynx, wild cat and fox (Vulpes melanotus). [35][36][37][38], DNA analysis shows that, apart from recent human-caused population fragmentation,[39] brown bears in North America are generally part of a single interconnected population system, with the exception of the population (or subspecies) in the Kodiak Archipelago, which has probably been isolated since the end of the last Ice Age. People who assert their presence through noises tend to be less vulnerable, as they alert bears to their presence.
