The composition (density, moisture content, piece-size, volume and pile profile) of full-tree logging residues left at roadside after the delimbing and topping operations was measured for both black spruce and jack pine stands. The performance of a modified prototype logging residue processor (LPR) which reclaimed and comminuted this material was also tested. Costs for the processed material loaded into a van for future conversion into energy and also for reclaiming the forest growing site under the roadside piles by spreading the comminuted residues over the cutover have been given.
