Brown bear
Even in populations living in protected areas, humans are still the leading cause of mortality for brown bears. The largest amount of legalized brown bear hunting occurs in Canada, Finland, Russia, Slovakia and Alaska. Hunting is unregulated in many areas within the range of the brown bear. Even where hunting is legally permitted, most biologists feel that the numbers hunted are excessive considering the low reproduction rate and sparse distribution of the species. Brown bears are also killed in collisions with automobiles, which is a significant cause of mortality in the United States and Europe.
