Alternate biomass harvesting systems using conventional equipment

Three harvesting methods were field tested in two stand types. Costs and stand utilization rates were developed for a conventional harvesting sys- tem, without energy wood recovery; a two-pass roundwood and energy wood system; and a one-pass system that har- vests roundwood and energy wood. The systems harvested 20-acre test blocks in two pine pulpwood plantations and in a natural pine sawtimber stand. The one-pass method resulted in the least cost and better utilization of biomass residue.
