Skyline thinning production and costs : experience from the Willamette Young Stand Project

Creator:: Kellogg, L. D. (Loren D.), Miller, Mark E., Olsen, Eldon D., and Oregon State University. Forest Research Laboratory
Abstract:: Production rates and costs for skyline harvesting were examined over a range of residual thinning intensities, operational methods, and sites. The sites included three stands of 40- to 50-yr-old Douglas-fir on the Willamette National Forest in the Cascade Mountains of Oregon. Three silvicultural treatments were studied at two sites, and...

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...

Logging planning and layout costs for thinning : experience from the Willamette Young Stand Project

Creator:: Kellogg, L. D. (Loren D.), Milota, Ginger, Stringham, Bennett, and Oregon State University. Forest Research Laboratory
Abstract:: Logging planning and layout costs were examined for commercial thinning of 40- to 50-yr-old stands of Douglas-fir on the Willamette National Forest in the Cascade Mountains of Oregon. The study consisted of four replications of three silvicultural treatments. Thinning involved three types of logging systems: mechanized cut-to-length (a combination of...

Response of arthropods to different intensities of thinning in Oregon

Creator:: Yi, Hoonbok
Abstract:: The process of silvicultural thinning has become very controversial recently with regards to fire protection and management for old-growth conditions and biodiversity. Therefore, an unthinned control stand and 3 different thinning intensities were examined for their effects on the abundance, species richness, and diversity of arthropods in thinning treatments of...

A handful of trails : Willamette National Forest

Creator:: United States. Forest Service. Pacific Northwest Region
Abstract:: The trails included in this book will lead you to mountain-top vistas, lakes, waterfalls and old-growth forests, towering secondgrowth forests, rocky bluffs and alpine meadows. We've included a variety of trails: • short walks for those seeking fresh air and a place to stretch their legs • medium length trails...

Historic fires in the central Western Cascades, Oregon

Creator:: Burke, Constance J.
Abstract:: The history of fire between 1850 and 1977 in a portion of the Willamette National Forest in-the central Western Cascades of Oregon was documented using historical sources. Three types of records were available: (1) records and writings not primarily concerned with fire but yielding information about fire in context with...

Buffer strip dynamics in the Western Oregon Cascades

Creator:: Sherwood, Kim
Abstract:: Although buffer strips have long been used as a protection tool when logging near streams, long-term studies investigating buffer strip dynamics are rare. Steinblums et al. (1984) inventoried 40 buffer strips 1 to 15 years old in the western Oregon Cascades beginning in the summer of 1975. Numerous site and...

Thinning aged Douglas-fir : an analysis of mobilization costs and a log bucking strategy for revenue improvement

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...
