Book Description
People have long valued mature western redcedar for its strong, lightweight wood that is rot-resistant.The species has cultural importance for Northwest tribes who use the trees bark and roots as well as the wood. Redcedar is very shade-tolerant and is often found in the understory and midstory of Pacific Northwest forests. It is also very adaptable and can grow on a wide range of site conditions in both single- and mixed-species stands. In contrast to Douglas-fir, the subject of countless studies related to its growth potential and response to management in the region, very little has been reported for redcedar. A series of studies conducted over 30 years on the responses of young growth redcedar to a wide range of stand, site, and management conditions has led researchers with the Pacific Northwest Research Station to conclude that redcedar is very responsive to management. For example, the species responded well to both thinning and fertilization on a nutrient-poor site, it didnt experience thinning shock when released from overtopping competition, and in a range-wide analysis, its growth rates held up better under competition than Douglas-fir. These findings are helping land managers evaluate opportunities for growing redcedar to meet multiple economic and ecological objectives.

Book Description
Excerpt from Response to Commercial Thinning in a 110-Year Old Douglas-Fir Stand The Boundary Creek thinning-study area is in the Panther Creek subdivision of the Wind River Experimental Forest near Carson, Washington, on the Wind River District of the Gifford Pinchot National Forest. The study area encompasses about 70 acres at an elevation of about 2500 feet. It occupies a slump basin with uneven topography. Slopes are generally less than 30 percent.

Book Description
The objective of this paper is to provide a global review of the non-wood uses of conifers. For the purposes of this paper, conifers are defined as trees and shrubs of the botanical orders Coniferales, Taxales and Ginkgoales (Rushforth 1987). Although some services are briefly mentioned, the focus of this paper is on products which conifers provide species, which are important sources of non-wood forest products, and places where these products are harvested. With the exception of essential oils, which can be obtained from several parts of the tree, the products described are organized by the part of the tree from which they are obtained (e.g. foliage, bark and roots, resin, seeds and cones). Where possible, data on levels of production and international trade are presented. Problems associated with the sustainable management of these products and compatibility or conflicts with other land uses are also presented. Both contemporary and historical or traditional uses of non-wood products from conifers are discussed.

Book Description
This book is exclusively concerned with wood modification, although many of these processes are generic and can be applied to other lignocellulosic materials. There have been many rapid developments in wood modification over the past decade and, in particular, there has been considerable progress made in the commercialisation of technologies. Topics covered include: The use of timber in the 21st century Modifying the properties of wood Chemical modification of wood: Acetic Anhydride Modification and reaction with other chemicals Thermal modification of wood Surface modification Impregnation modification Commercialisation of wood modification Environmental consideration and future developments This is the first time that a book has covered all wood modification technologies in one text. Although the book covers the main research developments in wood modification, it also puts wood modification into context and additionally deals with aspects of commercialisation and environmental impact. This book is very timely, because wood modification is undergoing huge developments at the present time, driven in part by environmental concerns regarding the use of wood treated with certain preservatives. There has been considerable commercial interest shown in wood modification over the past decade, with products based upon thermal modification, and furfurylation now being actively being marketed. The next few years will see the commercialisation of acetylation and impregnation modification. This is a new industry, but one that has enormous potential. This book will prove useful to all those with an interest in wood modification including researchers, technologists and professionals working in wood science and timber engineering, wood preservation, and well as professionals in the paper and pulp industries, and those with an interest in the development of renewable materials.
