This study measured the incidence of red squirrel (Tamiasciurus hudsonicus Erxleben) feeding injuries to thinned lodgepole pine (Pinus contorta Dougl. Var. latifolia Englem.) during the first 7 years after spacing. Squirrel feeding damage in two manually spaced stands was monitored from 1979 to 1986 (Prince George) and 1980 to 1986 (Cariboo); squirrel populations were monitored from 1981 to 1986 in a juvenile (unspaced stand) and mature stand at each area. Several silvicultural recommendations are suggested to alleviate squirrel damage to spaced lodgepole pine.
