Abstract:: Research on skyline machines and techniques currently available for yarding smallwood is reviewed. Three categories of machines are discussed: used yarders (with a low initial cost) adaptable to smallwood, new and versatile yarders (with a high Initial cost) manufactured in the United States, and new, foreign-built yarders (with a low...

Abstract:: The Forest Engineering Department, Oregon State University, has evaluated several systems for thinning young timber stands on steep terrain. Stands averaged 35 to 40 years old and 25.4 to 35.6 cm (10-14 in.) dbh. Approximately 40 percent of the stems per hectare were removed in the thinning operations. This paper...

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...

Abstract:: The production rates and costs of harvesting smallwood were determined for a small yarder (Koller K-300) operating under variable conditions: the size of the crew, the addition of a skidder to swing logs from the landing, and the type of harvest method-employed, either conventional or hot thinning (simultaneous felling and...

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...

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...

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:: "The purpose of this publication is to compile a standardized set of terminology for mechanized logging machinery and logging methods for the Pacific Northwest. While other organizations have produced similar works with either a wider or narrower focus (Dean and Evans 1978, Mifflin and Lysons 1979, Ford-Robertson 1983, Granvik et...

Abstract:: Recognition of the problems and opportunities in mechanized harvesting should help in development of solutions and maximum realization of its potential. This paper presents feedback from five working groups, the members of which were involved in mechanized harvesting issues with various organizations in the Pacific Northwest. The groups identified needs...
