Tractor thinning productivity and costs : experience from the Willamette Young Stand Project

Creator:

Kellogg, L. D. (Loren D.), Davis, Chad T. (Chad Thomas), and Oregon State University. Forest Research Laboratory

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...

Production and costs of cut-to-length thinning : experience from the Willamette Young Stand Project

Creator:

Kellogg, L. D. (Loren D.), Spong, Ben, and Oregon State University. Forest Research Laboratory

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...
