Download or read book Wood Variation written by Bruce J. Zobel and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wood is the usual end product of a forestry operation. Because of its importance, numerous studies have been made relative to wood prop erties, the causes of wood variation, and how best to develop wood for desired products. There is voluminous literature related to these subjects, but it is neither well known nor appreciated by foresters because the publications are often not available or are not well understood by the forester or by those who use the wood. Frequently, the literature is confusing and contradictory, making it difficult for the nonspecialist to use what information is available. In order to produce and use wood efficiently, the variation pat terns within trees, among trees within species, and among species must be understood. This also requires some knowledge of the causes of variation and the effects of different wood properties upon utiliza tion. The information about variation patterns, their causes, and con trol and effect upon the product must be known by the tree grower, the tree breeder, and the tree harvester as well as by those who ultimately convert wood into a final, salable product.
Book Synopsis Wood Quality and its Biological Basis by : John Barnett
Download or read book Wood Quality and its Biological Basis written by John Barnett and published by John Wiley & Sons. This book was released on 2009-02-18 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wood is the most versatile raw material available to man. It isburned as fuel, shaped into utensils, used as a structuralengineering material, converted into fibres for paper production,and put to newer uses as a source of industrial chemicals. Its quality results largely from the chemical and physicalstructure of the cell walls of its component fibres, which can bemodified in nature as the tree responds to physical environmentalstresses. Internal stresses can accumulate, which are releasedcatastrophically when the tree is felled, often rendering thetimber useless. The quality of timber as an engineering materialalso depends on the structure of the wood and the way in which ithas developed in the living tree. Tree improvement for quality cannot be carried out without anunderstanding of the biological basis underlying wood formation andstructure. This volume brings together the viewpoints of bothbiologists and physical scientists, covering the spectrum from theformation of wood to its structure and properties, and relatingthese properties to industrial use. This is a volume for researchers and professionals in plantphysiology, molecular biology and biochemistry.

Book Synopsis Ecosystem Management in the Boreal Forest by : Sylvie Gauthier
Download or read book Ecosystem Management in the Boreal Forest written by Sylvie Gauthier and published by PUQ. This book was released on 2009 with total page 574 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forest Ecosystem Management. A management approach that aims to maintain healthy and resilient forest ecosystems by focusing on a reduction of differences between natural and managed landscapes to ensure long-term maintenance of ecosystem functions and thereby retain the social and economic benefits they provide to society.That is the definition of forest ecosystem management proposed in this book, which provides a summary of key ecological concepts supporting this approach. The book includes a review of major disturbance regimes that shape the natural dynamics of the boreal forest and gives examples from different Canadian boreal regions. Several projects implementing the forest ecosystem management approach are presented to illustrate the challenges created by current forestry practices and the solutions that this new approach can provide. In short, knowledge and understanding of forest dynamics can serve as a guide for forest management. Planning interventions based on natural dynamics can facilitate reconciliation between forest harvesting needs and the interests of other forest users.
Book Synopsis Size- and Age-Related Changes in Tree Structure and Function by : Frederick C. Meinzer
Download or read book Size- and Age-Related Changes in Tree Structure and Function written by Frederick C. Meinzer and published by Springer Science & Business Media. This book was released on 2011-06-29 with total page 511 pages. Available in PDF, EPUB and Kindle. Book excerpt: Millions of trees live and grow all around us, and we all recognize the vital role they play in the world’s ecosystems. Publicity campaigns exhort us to plant yet more. Yet until recently comparatively little was known about the root causes of the physical changes that attend their growth. Since trees typically increase in size by three to four orders of magnitude in their journey to maturity, this gap in our knowledge has been a crucial issue to address. Here at last is a synthesis of the current state of our knowledge about both the causes and consequences of ontogenetic changes in key features of tree structure and function. During their ontogeny, trees undergo numerous changes in their physiological function, the structure and mechanical properties of their wood, and overall architecture and allometry. This book examines the central interplay between these changes and tree size and age. It also explores the impact these changes can have, at the level of the individual tree, on the emerging characteristics of forest ecosystems at various stages of their development. The analysis offers an explanation for the importance of discriminating between the varied physical properties arising from the nexus of size and age, as well as highlighting the implications these ontogenetic changes have for commercial forestry and climate change. This important and timely summation of our knowledge base in this area, written by highly respected researchers, will be of huge interest, not only to researchers, but also to forest managers and silviculturists.

Available in PDF, EPUB and Kindle. Book excerpt: Canada's forests are one of its most important natural resources. Since the arrival of the earliet settlers, the forests have played a major role in the country's development, supplying the raw material for the necessities of life and for much of our industry. Completely revised and expanded, this edition of Canadian Woods is a comprehensive overview of a multi-faceted forest industry. Providing a complete review of the woods found in Canada and their commercial uses, it discusses the structure, the strength and physical properties, and the chemistry of wood, plus lumber production, wood drying, ood protection, and glues and gluing. Other chapters deal with the processing and use of woods and wood products, panel products, houses and structures, pulp and paper, and codes and standards in Canada. Lavishly illustrated with moer than 280 photographs and drawings, the newly revised Canadian Woods is an essential reference for students and practitioners in the forest professions and in primary and secondary forest industries.

Book Synopsis Qualité du bois et de la fibre d'épinette noire après coupe partielle by : Braido Dos Santos Diego Valerio
Download or read book Qualité du bois et de la fibre d'épinette noire après coupe partielle written by Braido Dos Santos Diego Valerio and published by Editions Universitaires Europeennes. This book was released on 2015-08-10 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les coupes partielles sont une alternative a la coupe totale en etant appliquees dans le but d'assurer l'approvisionnement en fibres et de maintenir la biodiversite ainsi que d'ameliorer la croissance radiale des arbres. Neanmoins, peu d'etudes ont evalue l'evolution de la qualite du bois avec le temps apres le traitement. L'impact des 3 intensites des coupes partielles a ete evalue sur la longueur et la largeur des tracheides ainsi que sur la largeur et la masse volumique du bois de l'epinette noire. Les variations intra-arbres de ces proprietes avant les coupes partielles furent aussi etudiees. Les mesures ont ete faites a differentes hauteurs dans l'arbre, sur 5 annees et sur 4 classes de DHP. La variation radiale de toutes les proprietes etudiees a ete plus prononcee que la longitudinale et plus importantes dans le bois juvenile. Malgre l'effet positif des coupes partielles sur la croissance annuelle, il n'a pas d'implications pratiques ni industrielles sur la qualite de la fibre et du bois d'epinette noire. Cette publication vise des lectorats des domaines academiques et industriels qui s'interessent aux impacts des pratiques sylvicoles sur la qualite du bois"
