We then developed a Bayesian network model that allows managers to estimate the potential effects of recreational management decisions in bear habitats. Decreased body condition and ultimately decreased reproductive success can occur if disturbance leads to decreased food intake or increased energy expenditure, theoretically having a population level impact [ 15 , 19 , 23 ]. My grizzlies and Kodiaks are the hardest to tame, but the easiest to train; generally you only have to teach them something once.

Bears eat carrion willingly but already since years our cattle-owners are obliged to take their dead animals to an animal carcass disposal centre. Though we edit our accounts for accuracy, we cannot guarantee all information in those accounts. The Scandinavian Brown Bear Project.

Bears that have access to salmon streams tend to be larger and have more offspring than other bears. Generally they seek a high remote mountain slope where deep snow will lie until spring to serve as insulation.
