Brown Bear - Relationship With Humans

Relationship With Humans

Bears become attracted to human-created food sources, such as garbage dumps, litter bins, and dumpsters; they venture into human dwellings or barns in search of food as humans encroach into bear habitats. In the U.S., bears sometimes kill and eat farm animals. When bears come to associate human activity with a "food reward", they are likely to continue to become emboldened; the likelihood of human-bear encounters increases, as they may return to the same location despite relocation. The saying "a fed bear is a dead bear" has come into use to popularize the idea that allowing bears to scavenge human garbage, such as trash cans and campers' backpacks, pet food, or other food sources that draw the bear into contact with humans, can result in a bear's death.

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. "Placing a bear in habitat used by other bears may lead to competition and social conflict, and result in the injury or death of the less dominant bear."

Yellowstone National Park, an enormous reserve located in the western United States, contains prime habitat for the grizzly bear (Ursus arctos horribilis), and due to the enormous number of visitors, human-bear encounters are common. The scenic beauty of the area has led to an influx of people moving into the area. In addition, because there are so many bear relocations to the same remote areas of Yellowstone, and because male bears tend to dominate the center of the relocation zone, female bears tend to be pushed to the boundaries of the region and beyond. As a result, a large proportion of repeat offenders, bears that are killed for public safety, are females. This creates a further depressive effect on an already endangered species. The grizzly bear is officially described as "threatened" in the U.S. Though the problem is most significant with regard to grizzlies, these issues affect the other types of brown bears as well.

In Europe, part of the problem lies with shepherds; over the past two centuries, many sheep and goat herders have gradually abandoned the more traditional practice of using dogs to guard flocks, which have concurrently grown larger. Typically, they allow the herds to graze freely over sizeable tracts of land. As bears reclaim parts of their range, they may eat livestock. In some cases, the shepherds shoot the bear, thinking their livelihood is under threat. Many are now better informed about the ample compensation available, and will make a claim when they lose livestock to a bear.

It is likely that humans caused extinction of bear populations and fragmentation of their habitats since prehistorical time. It is, for instance, shown that bear populations from the Greater Caucasus and the Lesser Caucasus Mountains, separated by densely populated Transcaucasian Depression, are matrilineally isolated since early Holocene, i.e. after permanent human settlements appeared throughout the area
