BLACK BEAR PREDATION ON YOUNG CERVIDS - A SUMMARY
A literature search and personal communication with many field workers across North America, suggests that predation by black bear (Ursus americanus) upon neonate cervids may adversely affect recruitment in cervid populations. Such predation appears most important within the first two months followi...
