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,...

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...

Increasing the productivity of a small yarder : crew size, skidder swinging, hot thinning

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

An efficient optimizing model for determining thinning regime and rotation age using the stand projection system growth simulator

Creator:: Yoshimoto, Atsushi
Abstract:: The PATH algorithm, which is the efficient dynamic programming algorithm developed by Paredes and Brodie (1987) was interpreted from a different point of view. This modification of the PATH algorithm by the calculus of variations vastly diminished the calculation task and memory required to store optimal stands at each stage....

Response of young Douglas-fir to 16 years of intensive thinning

Creator:: Tappeiner, J. C. (John C.), Bell, John F., Brodie, J. Douglas (John Douglas), 1938-, and Oregon State University. Forest Research Laboratory
Abstract:: A 20-year-old Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco] stand in the Oregon Coast Range was thinned from about 1,700 to about 350 trees/ac. Subsequent thinnings, under eight different regimes, occurred at ages 23, 27, 30, and 32. Average net periodic cubic-volume growth was strongly influenced by thinning regime, varying from about...

Effect of thinning and fertilization on wood properties and intra-ring characteristics in young Douglas-fir

Creator:: Bodner, Josef
Abstract:: The purpose of this study was to determine if thinning, fertilization or a combination of thinning and fertilization had an effect on overall average specific gravity, modulus of elasticity, modulus of rupture, fiber length and intra-ring characteristics. Material for this experiment consisted of 7 trees randomly selected from each of...

A simulation of the comparative costs and benefits of skyline strip thinning

Creator:: LeDoux, Chris B.
Abstract:: Strip thinning is recognized as a way of commercial thinning young-growth stands. strip thinning has been used worldwide. The purpose of this study was to explicitly evaluate the costs and benefits associated with skyline strip thinning in young Douglas-fir (Pseudotuqo menzesii Franco) stands in the Pacific Northwest and to compare...
