Black bear damage to lodgepole pine in central Oregon

Black bear damage to 108 lodgepole pine trees was found in 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.
