The production potential of the Ingland-Jones Trailer Alp yarder in thinning young growth northwest conifers: a case study

Creator:: Neilson, Dennis Albert
Abstract:: Results of a recent production study indicate that a four man crew thinning young growth Douglas-fir [Pseudotsuga mensiezii (Mirb.) Franco] with an Iglarid-Jones Trailer Alp can produce 1360 to 1460 cubic feet (38 to 41 cubic metres; 8160 to 8750 bd. ft.,) per eight hour day on slopes of 10...

Thinning : an important timber management tool

Creator:: Emmingham, William H. and Elwood, Norman E.
Abstract:: Explains how seedlings grow into mature trees and how stands of trees develop. Describes basic tree growth and growth processes (photosynthesis, respiration, and translocation-assimilation). Discusses how thinning affects individual tree growth and stand growth, including growth responses, thinning shock, tolerance levels of common Pacific Northwest tree species, crown classification systems,...

Yields of repeated high and low commercial thinnings of immature coastal Western hemlock

Creator:: Hilt, Donald E.
Abstract:: Commercial thinnings in a 50-year-old stand of nearly pure, well stocked, even-aged western hemlock (Tsuga heterophylla) on the Hemlock Experimental Forest near Hoquiam, Washington, began in 1952 and ended in 1968. The experiment consisted of two replications of four different thinning treatments, high and low thinning, both at frequent and...

The use of a three-stage sample to estimate the effect of commercial thinning on the growth of two stands of Douglas-fir

Creator:: Graham, Joseph Nelson
Abstract:: A three stage sale was taken of two high-site, second growth Doug1as-fir (Pseudtsuga menziesii) stands located in the extreme northwestern portion of the Oregon Coast Range. Permanent plots were established during the first stage variable-plot cruise. A Hartley- List sample, taken from the first stage Douglas-fir in trees, selected second...

The effect of thinning intensity upon understory growth and species composition in an Oregon Coast Range Pseudotsuga menziesii stand

Creator:: Witler, Jerome Warren
Abstract:: Cover, frequency, and biomass of under story vegetation were estimated on 14 study plots in a central Oregon Coast Range Pseudotsuga menziesii stand. The treatments included a control and three different thinning intensities. Basal area of active growing stock, defined as young-growth P. menziesii with diameter at breast height of...

The evaluation of competitive stress index as a measure of stand density for young growth Douglas-fir

Creator:: Smith, Stephen H.
Abstract:: The study evaluates the use of Competitive Stress Index (CSI) as a quantitative measure of stand density in a young-growth Douglas-fir stand in Western Oregon which had been subjected to various thinning regimes. Operational applications of the index are examined and new methodologies presented for the analysis of tree and...

Simulating skyline yarding in thinning young forests

Creator:: Sinner, Hans-Ulrich
Abstract:: Cable logging systems are being applied frequently in thinning young-growth forests, but the dynamics of these systems are relatively unknown. This study is part of a research project to develop aerial logging systems for thinning and to analyze them for economic, silvicultural, and environmental implications. The objectives of my study...

Thinning young timber stands in mountainous terrain

Creator:: Kellogg, L. D. (Loren D.) and Oregon State University. Forest Research Laboratory
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...

The effect of forest stand thinning on selected strength and pulp-ing characteristics of Douglas-fir

Creator:: Johnson, Donna A.
Abstract:: The purpose of this study was to determine if amount and kind of thinning had an effect on wood specific gravity, modulus of rupture, modulus of elasticity, growth rate, or pulp yield and kappa number. The study involved 24 1/5-acre plots, three plots in each of eight thinning treatments. The...
