Abstract
Barking damage by snowshoe hares (Lepusamericanus Erxleben) and red squirrels (Tamiasciurushudsonicus Erxleben) is common in overstocked stands of juvenile lodgepole pine (Pinusconforta Dougl.) in central British Columbia. Average proportion of potential crop trees damaged by hares was 30.0% and by squirrels was 37.7%. Most hare feeding injuries occurred in heavily stocked (> 20 000 stems/ha) stands, whereas squirrel damage was most common in less dense stands. Both animal species damaged trees in thinned stands, and hence may have a serious impact on stocking control programs in lodgepole pine.
