Book excerpt: There is no question that the timber industry needs to adopt sustainable practices that ensure a future for the industry. This book goes well beyond simply growing commercial tree plantations for wood production. It explores new forests that can supply environmental services such as salinity mitigation and carbon sequestration together with commercial wood production in an environment beyond the boundaries of traditional forestry. New Forests targets agricultural landscapes affected by salinity and which generally have rainfall less than 650 mm per year. The book addresses vital issues such as where tree planting might best be pursued, what species and technologies should be used for establishment and later management, how productivity can be improved, what mix of environmental services and commercial goods is optimum, and whether the likely net benefits justify the change in land use and requisite investment. While the book is focussed on the low-rainfall, agricultural, inland zone of the Murray-Darling Basin wherever possible the scope of most chapters has been expanded to synthesise generic information applicable to other regions in Australia and elsewhere. The authors provide a comprehensive account of all the issues relevant to the development of these new forests, covering soils, the bio-physical environment, water use and irrigation strategies - including the use of wastewater, silviculture, pests and diseases, wood quality and products, and economics and policy implications.

Download or read book The Biology of Reaction Wood written by Barry Gardiner and published by Springer Science & Business Media. This book was released on 2014-01-08 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book is a fundamental reference source on reaction wood for wood scientists and technologists, plant biologists, silviculturists, forest ecologists, and anyone involved in the growing of trees and the processing of wood. It brings together our current understanding of all aspects of reaction wood, and is the first book to discuss both compression wood and tension wood. Trees produce reaction wood to maintain the vertical orientation of their stems and the optimum angle of each branch. They achieve this by laying down fibre cell walls in which differences in physical and chemical structure from those of normal fibres are expressed as differential stresses across the stem or branch. This process, while of obvious value for the survival of the tree, causes serious problems for the utilisation of timber. Timber derived from trees containing significant amounts of reaction wood is subject to dimensional instability on drying, causing twisting, bending and splitting. It is also difficult to work as timber, and for the pulp and paper industry the cost of removing the increased amount of lignin in compression wood is substantial. This has both practical and economic consequences for industry. Understanding the factors controlling reaction wood formation and its effect on wood structure is therefore fundamental to our understanding of the adaptation of trees to their environment and to the sustainable use of wood. The topics covered include: -Morphology, anatomy and ultrastructure of reaction wood -Cell-wall polymers in reaction wood and their biosynthesis -Changes in tree proteomes during reaction wood formation -The biomechanical action and biological functions of reaction wood - Physical and mechanical properties of reaction wood from the scale of cell walls to planks -The detection and characterisation of compression wood -Effects of reaction wood on the performance of wood and wood-based products - Commercial implications of reaction wood and the influence of forest management on its formation

Download or read book Agroforestry for Natural Resource Management written by Ian Nuberg and published by CSIRO PUBLISHING. This book was released on 2009-05-18 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: In its early days, agroforestry may have been viewed as the domain of the 'landcare enthusiast'. Today, integrating trees and shrubs into productive farming systems is seen as a core principle of sustainable agriculture. Agroforestry for Natural Resource Management provides the foundation for an understanding of agroforestry practice in both high and low rainfall zones across Australia. Three major areas are discussed: environmental functions of trees in the landscape (ecosystem mimicry, hydrology, protection of crops, animals and soil, biodiversity, aesthetics); productive functions of trees (timber, firewood, pulp, fodder, integrated multi-products); and the implementation of agroforestry (design, evaluation, establishment, adoption, policy support). The book also includes a DVD that features videos on forest measurement and harvesting, a Farm Forestry Toolbox and many regionally specific agroforestry resources. Written by leading researchers and practitioners from around Australia, Agroforestry for Natural Resource Management will be an essential resource for students in agroforestry courses, as well as a valuable introduction to the field for professionals in related areas.

Download or read book Wood Properties and Processing written by Miha Humar and published by MDPI. This book was released on 2020-05-23 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wood-based materials are CO2-neutral, renewable, and considered to be environmentally friendly. The huge variety of wood species and wood-based composites allows a wide scope of creative and esthetic alternatives to materials with higher environmental impacts during production, use and disposal. Quality of wood is influenced by the genetic and environmental factors. One of the emerging uses of wood are building and construction applications. Modern building and construction practices would not be possible without use of wood or wood-based composites. The use of composites enables using wood of lower quality for the production of materials with engineered properties for specific target applications. Even more, the utilization of such reinforcing particles as carbon nanotubes and nanocellulose enables development of a new generation of composites with even better properties. The positive aspect of decomposability of waste wood can turn into the opposite when wood or wood-based materials are exposed to weathering, moisture oscillations, different discolorations, and degrading organisms. Protective measures are therefore unavoidable for many outdoor applications. Resistance of wood against different aging factors is always a combined effect of toxic or inhibiting ingredients on the one hand, and of structural, anatomical, or chemical ways of excluding moisture on the other.

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.

Download or read book Wood Water Relations written by Christen Skaar and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wood is formed in an essentially water-saturated environment in the living tree, and the cell wall remains in this state until the water flow from the roots is interrupted, such as by felling the tree. The wood then begins to lose most of its moisture by drying, resulting in changes in most of its physical properties. These changes, and their relationship to the environment to which the wood is subsequently ex posed, are the subject of this book. The text consists of six chapters. The first chapter discusses cer tain empirical relationships between wood and water, methods of measuring wood moisture content, factors which affect its equilib rium moisture content, and the effect of moisture content on wood strength. The second chapter treats the thermodynamics of moisture sorption by wood, inc1uding enthalpy, entropy, and free energy changes. The third chapter discusses some of the theories which have been proposed to explain the sorption isotherms for hygroscopic ma terials such as wood. Chapter 4 considers hygroexpansion or the shrinking and swelling of wood associated with moisture change. Chapter 5 is concerned with how moisture moves through the cell wall of wood in response to both moisture and temperature gradients. The sixth and final chapter discusses the theoretical and practical aspects of the electrical resistance and dielectric properties of wood, in c1uding the principles involved in their application in electrical moisture meters.
