EFFECTS OF BLACK BEAR PREDATION ON CARIBOU--A REVIEW

Abstract

I reviewed available literature concerning black bear (Ursus americanus) predation on caribou (Rangifer tarandus) in an effort to gain insight on the possible impacts of black bear predation on a potential re-introduction of woodland caribou (Rangifer tarandus caribou) to north-central Minnesota. Several case histories were reviewed and inferences were drawn from several black bear-moose (Alces alces) studies. I concluded that black bear predation on woodland caribou in the proposed re-introduction area would likely be a secondary source of caribou mortality and that between 6-30% of the calves and 0-5% adults might be killed annually by black bears.
