Soil disturbance assessment of a cable logging operation performing five silvicultural prescriptions
Evaluating alternative methods for regenerating second-growth Douglas-fir (Pseudotsuga menziesii) forests in the Pacific Northwest is an area of interest for resource managers. To meet future demands for timber supply as well as provide stands that are visually acceptable by the public and ecologically viable, a thorough understanding of these alternative silvicultural prescriptions in terms of stand productivity and site impacts from harvesting must exist. In addition, implementing these prescriptions during the harvest phase must be economically feasible. While some areas are located on gentle terrain that can be harvested using conventional ground-based systems, other areas are characterized by steep terrain, which must be harvested with cable systems. Knowledge of site impacts in terms of soil surface disturbance associated with each of these harvest systems is beneficial to resource managers.
