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.
