Practical methodology for operational layout of commercial skyline thinning systems

Creator:: Cornell, Jennie L., Kellogg, L. D. (Loren D.), and Oregon State University. Forest Research Laboratory
Abstract:: On-the-ground harvest unit layout, especially in skyline-thinning operations, is critical to meeting multiple resource objectives of the land manager and maintaining the economic viability of the timber harvesting operator. This phase of an operation can optimize the layout and harvesting of a sale or unit. Detailed layout by a knowledgeable...

Reducing hazardous fuels on woodland property: thinning

Creator:: Parker, Robert T., Bennett, Max, 1963-, and Oregon State University. Extension Service
Abstract:: Thinning is one of the most powerful forest management tools available to landowners for achieving a wide range of goals and objectives. Thinning influences: • Trees’ growth rates and potential economic value • Which species of trees and other plants will be in the stand • Trees’ resistance to insects...

Impacts of fuel reduction thinning treatments on oak and chaparral communities of southwestern Oregon

Creator:: Perchemlides, Keith A.
Abstract:: In response to concerns about excessive stand densities and high-severity wildfires, land managers in the western United States are carrying out extensive programs of fuel reduction thinning. How will these sudden reductions in canopy cover and associated changes in habitat affect native and exotic herbaceous vegetation and canopy species regeneration?...

Arthropod communities on understory plants in thinned and unthinned Douglas-fir forests in the Oregon Coast Range

Creator:: Doolittle, Alyssa M.
Abstract:: This study assessed the effects of thinning on arthropod communities on understory plants in the Central Oregon Coast Range. Arthropods were sampled from five understory plants in five pairs of thinned and unthinned, young (50-80 yrs), managed Douglas-fir stands, from late May to mid-July of 1998. Vine maple (Acer circinatum),...

Science basis for changing forest structure to modify wildfire behavior and severity

Creator:: Graham, Russell T., McCaffrey, Sarah, and Jain, Theresa B.
Abstract:: Fire, other disturbances, physical setting, weather, and climate shape the structure and function of forests throughout the Western United States. More than 80 years of fire research have shown that physical setting, fuels, and weather combine to determine wildfire intensity (the rate at which it consumes fuel) and severity (the...

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...

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...

Thinning with prescribed fire and timber harvesting mechanization for fuels reduction and forest restoration

Creator:: Matzka, Peter J.
Abstract:: In the Blue Mountains of northeastern Oregon, prescribed fire and mechanical harvesting economics were investigated for fuels reduction and forest restoration. Using a cut-to-length harvesting system, three single-grip harvesters and three forwarders produced significantly different production rates. For the harvesters, significant variables that affected production rates were found to be:...

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...

Botanical composition and diet quality of beef cattle grazing at three stocking rates following fuels reduction in mixed conifer forests

Creator:: Clark, Abe A.
Abstract:: An experiment was conducted to evaluate the influence of forest fuels reduction on the diet quality, botanical composition, relative preference, and foraging efficiency of beef cattle grazing at different stocking rates. A split plot factorial design was used, with the whole plots (3 ha) being fuel reduced or no treatment...
