Abstract
This study was conducted to assess the costs of various site preparation methods with various levels of harvesting Site impacts, soil compaction and disturbance were examined. Three hawesting methods rare evaluated in pine pulpwood plantation and pine sawtimber stands. The harvesting methods tested were (1) conventional - harvesting all roundwood. (2) two-pass - first harvesting of energy uood followed by conventfonal harvesting of fiber and logs, and (3) one-pass - harvesting all in one operation. The site preparatoin mehtods tested were (1) shear-rake-pile. (2) single disk. (3) double disk, and (4) herbicide treatments.The results of the study indicate that conventional harvesting system can be used to harvest energy wood components of some stand types. The integration of biomass harvesting and site preparation can result in a credit to be applied to the harvesting or site preparation operations. One-pass harvesting has the most potential for reducing harvest costs for some stand hypes. Single disking has the most site preparatoin savings. In most cases, the soil characteristics were returned to comparable conditions after site preparation.
