Creator:: Pilkerton, Stephen J.
Abstract:: Contract harvest operations have become the preferred approach to reducing the largest cost component of timber production through free market competition amongst logging contractors bidding or negotiating for work. The goal of this research was to investigate economic components of harvesting operations not previously studied for steep slope thinning harvests...

Abstract:: Harvesting productivity rates and costs were determined for three silvicultural treatments used in commercial ground-based thinning of young stands to achieve timber management objectives and enhance wildlife habitat. Treatment definitions were based on residual trees per acre (tpa) after thinning. The treatments were light thin (115 residual tpa), light thin...

Abstract:: Young Douglas-fir stands were commercially thinned to achieve vegetation- and wildlife-related objectives. Harvesting and forwarding production and costs were compared among three mechanized thinning treatments: light thin [(115 residual trees per acre (tpa)], light thin with 0.5-ac openings (92 residual tpa), and heavy thin (53 residual tpa). The sites were...

Creator:: Feeney, Daniel John
Abstract:: This thesis describes the results of a project conducted to determine the economics of forest road maintenance alternatives between periods of timber harvesting. An open road and a closed road alternative will be compared to the economics of clearcutting an entire area and obliterating the road system until reentry at...
