This report analyzes the economic worth of harvesting and hauling jack pine full trees to a central processing plant to recover conventional forest products at the same time as branches and tops for energy. The report summarizes results of winter and summer field tests of cut-and- skid and feller-forwarder harvesting methods. Results indicate that energy biomass recovered may be attractive where hauling occurs over private roads and oversized loads are allowed. Some scenarios are positive even when energy values are zero due to the high productivity of centralized equipment.
