Abstract
Abstract Logging planning, felling, and cable yarding costs were determined for five group-selection treatments and a clearcut in a 90 yr old Douglas-fir (Pseudotsuga menziesii) stand in western Oregon. The harvesting system included manual felling and a yarder rigged in a standing skyline configuration with a mechanical slackpulling carriage. The clearcut treatment had the lowest total harvest cost; costs of the group-selection treatments were 7.3 to 31.5% higher than the clearcut. Yarding cost associated with road and landing changes, plus the cost of equipment moving, set up, and tear down allocated over different treatment volumes removed had the biggest influence on total cost for each silvicultural treatment.
