DescriptionConventional harvesting equipment was tested for removing forest understory biomass (energywood) for use as fuel. Two types of systems were tested--a one-pass system and a two-pass system. In the one-pass system, the energywood and pulpwood were harvested simultaneously. In the two-pass system, the energywood was harvested in a first pass through the stand, and the pulpwood was harvested iris second pass. These systems were tested over a range of understory biomass amounts. Equations were developed to estimate the cost per green ton of energywood. The two-pass system exhibited high harvesting costs when biomass amounts were low, but costs moderated as biomass amounts increased. The one-pass system harvesting costs were not sensitive to the amount of energywood present.
