Book excerpt: Reductions of stand densities by precommercial thinning has become an important management tool to establish stabilized stands of western larch and to concentrate stand growth potential on fewer trees. The intent of the study reported was to provide basic information on the relationship between tree spacing and the two major wood quality parameters, wood density and branch size, to support stand management decisions. Wood density profiles and branch measurements were obtained from sample trees chosen from four Montana sites representing different stocking levels. Results are presented and discussed with regard to such parameters as tree height, diameter, tree volume, wood density, branch size, and the use of one- and two-stage thinning.

Book Synopsis Influence of Spacing and Crown Recession on Wood Quality of Intensively-managed Young-growth Douglas-fir by : James Michael Robbins
Download or read book Influence of Spacing and Crown Recession on Wood Quality of Intensively-managed Young-growth Douglas-fir written by James Michael Robbins and published by . This book was released on 2000 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: Intensive management of young-growth Douglas-fir plantations has emphasized volume growth over wood quality. A better understanding of the variables that affect wood quality is needed so that wood quality and stand yield can be systematically combined into a silviculture program. This experiment utilized two separate experiments to establish the relationship bebtwen wood quality, stand density, and artificial pruning. The influence of initial stand density on branch diameter, wood density, and tracheid length was explored utilizing 56 trees, 19 and 21 years old, at two sites in central western Oregon. Trees were sampled from Nelder plots ranging in density from 309 trees/ha to 18,730 trees/ha. The effects of fixed-height pruning on wood density and tracheid length were investigated using trees 23, 26, and 28 years old, after ten years of growth following pruning. Mean branch diameter, maximum branch diameter, number of branches/m, longevity of radial branch growth, and longevity of terminal branch growth all increased with decreasing initial tree density. After accounting for initial tree density, 1:2 rectangularity of spacing did not affect indicators of wood quality relative to 1:1 rectangularity of spacing. When age was held constant, there was no evidence that either wood density or tracheid length at breast height varied with initial tree density or crown characteristics. In contrast, there was evidence that ring density, earlywood density, and percent latewood increased linearly with initial tree density at the 5.27 m sampling height. There was no significant change in growth rate or wood density at breast height (1.37 m) or 5.27 m as a result of pruning 15% or less of the live crown length. In contrast, pruning to 5.5 m at age 13 resulted in a one-year decrease in earlywood width and an increase in percent latewood at 1.37 m. At the 5.27 m sampling height, there was a temporary increase in earlywood density, percent latewood, and mean ring density. Pruning at age 13 to 3.4 m and 5.5 m resulted in an increase in mean, earlywood, and latewood tracheid length of approximately 6% for three years. Wide initial spacing, combined with pruning appears to be the best choice for improving wood quality of Douglas-fir. Even though juvenile wood volume will be greater due to wide spacing, the increase in log diameter and clear wood volume will enhance log grade, especially if pruning occurs early in the rotation and is combined with commercial thinning to promote diameter growth.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Thinning Western Larch Overstocking threatens production on more than 1 million acres of western larch (larix occidentalis Nutt.) in the northern Rocky Mountains Dense stands have developed on favorable seedbeds found on many large burns and cutover areas in this region. The great number of stems in many of these stands precludes Optimum growth and development of individual trees because growth is being distributed over too many stems per acre. These trees are likely to remain overcrowded for long periods if stands are unmanaged. Trees in such stands will not reach commercially desirable size within a reasonable time. The obvious solution to the over stocking problem is thinning. Few western larch stands have been thinned, and little information has been published on thinnings in larch. Forest managers are now guided principally by information developed in other forest types This paper reports results of two western larch thinning studies located on the Lolo National Forest in western Montana. Briefly, the results show that diameter, basal area, height, and cubic-foot volume growth can be improved by thinning. Concentrating growth on fewer trees per acre Will produce larger trees earlier.

This book was released on 2018-10-07 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Levels-of-Growing-Stock Study in Thinned Western Larch Pole Stands in Eastern Oregon In terms of timber management, the primary factor influencing the residual stocking level is the forester's estimate of the minimum size tree that will be merchantable in the future. The larger the trees must be to support a commercial thinning, the fewer trees should be left after precommercial thinning; and conversely, if smaller trees are merchantable, the residual stocking should be higher. Western larch (larix occidentalis Nutt.) is a valuable seral species in the mixed conifer forests of north eastern Oregon because of its fast growth rate and desirable wood proper ties. Even-aged larch stands generally become established following fire or other forest disturbances. These stands are often heavily overstocked as seedlings. Stand density control by thinning is an essential part of the management of young larch stands. Because of the shade intolerance of larch, tree crowns in unthinned stands are reduced in size resulting in a decrease in rates of diameter and height growth as early as 9 years of age (schmidt The increasing utilization of larch and other species and the associated intensification of forest management raises questions regarding suitable stocking level regimes for managed larch stands.
