In-woods processing of aspen logs for pulp chips would allow industry to access and utilize aspen fibre in pure and mixedwood stands where conventional logging and haulage practices are not economically possible. This would have the effect of increasing fibre yield for individual cutblocks and at the landscape level. However, the disposal of the debarking waste (hog) on the cutblock may have an impact on future regeneration of aspen stems. During the years 1996 through 1998, three aspen cutblocks in the Dawson Creek Forest District were treated with aspen hog from an in-woods chipper. The purpose of these field treatments was to determine the effect of disposal of debarking waste on the regeneration of the treated aspen cutblocks. This proposal requests funding for fifth-year re-measurements of one set of treatment established in 1997. The information will be used by foresters exploring ways of increasing the yield of the forest land base and to determine the impact of in-woods chipping practices on stand yield and local ecosystem health.
