Currently, aspen (Populus tremuloides) fibre on British Columbia crown land is not utilized to its full potential. In-woods chipping has been proposed as one operational method that would increase the utilization of aspen fibre from boreal aspen and mixedwood stands. Results of a cost analysis of in-woods chipping demonstrated a 10 to 27% reduction in the cost of harvesting and shipping fibre over that of logging for roundwood. However, in-woods chipping results in the disposal of wood and bark waste (hog) in harvested cutblocks. Concern has been expressed regarding the impact of this waste upon subsequent regeneration and growth of trembling aspen. This proposal is asking for money to fund the fifth-year re-measurements of suckers on the third of three aspen cutblocks treated with hog between 1997 and 1999 (Forest Renewal B.C. project HQ96401-RE). This year's re-measurements will represent the completion of the short-term objectives of this work.
