    Analyses of time and cost data gathered on the Voight Creek Experimental Forest from six thinnings in a 50-year-old stand of Douglas-fir showed that average skidding distance and diameter of average tree cut were the chief factors affecting the production time in thinning these pulpwood stands. Cut per acre had negligible influence. Contractors' production efficiency over a 3-year period averaged 2.65 man-hours per cord. Delivered-to-plant harvesting costs totaled $16.37 per cord of pulpwood, including allowances for landowner's expense.
