Abstract
Black bear (Ursus amerlcanus) damage to 108 lodgepole pine (Pinus contorta) trees was found in a mixed conifer habitat in central Oregon. No trees of three other conifer species were injured. Eighty-nine percent of the damage occurred in the same year. Nearly 20% of the freshly damaged trees had bark removed from more than 75% of the circumference and, judging from the fate of trees damaged in prior years, probably succumbed.
