Introduction. In order for wood to be used to make wood composites, feedstock must first be obtained from trees and logs, which in themselves contain material of variable quality depending on a number of factors such as species, site location, age and position within the stem (Larson, ).Products such as plywood and laminated veneer lumber (LVL) are made from plies that are obtained Cited by: 3.

Previous studies of the within tree variation in density of western hemlock have constructed 2 dimensional maps of the variation in wood density from pith to bark and longitudinally within the tree, and have concluded that wood from the outer part of the stem is denser than wood found near the centre of the tree, and wood density decreases with tree height.
Based on such information it should. In this thesis genecology, phylogeography, and quantitative genetics of red alder were investigated. Further, literature with respect to red alder product values, market demand, forest resources, and red alder biology were reviewed. Implications of these aspects for genetic resources management were evaluated and a breeding strategy for red alder in British Columbia was developed.
Genetic. Our lumber mills continued to have improved lumber recovery and better grade yield. Production increased almost 50 MMBF to set a new company record. The Real Estate segment continued to sell non-core timberlands at margins in excess of 60%.
Higher lumber prices for were affected by several factors, including: . With over half of our total revenues indexed to lumber, increased lumber sale prices contributed to strong results for We also benefited from higher cedar log prices and a greater mix of cedar.

This is an illegal but lucrative business, since the income of the trappers from selling these birds is very high. You often hear it said that it is necessary to clearcut Douglas fir because it needs full sunlight. And the fact of the matter is quite to the contrary: it is not necessary to create large clearcuts to reproduce Douglas fir * * * insofar as the ecological requirements of the species are concerned.

Structural composites such as laminated veneer lumber, parallel strand lumber, and wood composite I beams allowed the use of less wood for a given application, thereby further stretching wood supplies.
