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.
Book Synopsis Productivity of Western Forests by :
Download or read book Productivity of Western Forests written by and published by . This book was released on 2005 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: In August 20-23, 2004, a conference was held in Kamilche, WA, with the title S2Productivity of Western Forests: A Forest Products Focus. S3 The meeting brought together researchers and practitioners interested in discussing the economic and biological factors influencing wood production and value. One of the underlying assumptions of the meeting organizers was that management activities would be practiced within a framework of sustaining or improving site productivity; thus, several papers deal with methods to protect or improve productivity or discuss new studies designed to test the effects of various practices. This proceedings includes 11 papers based on oral presentations at the conference, 3 papers based on posters and 2 papers describing the Fall River and Matlock Long-Term Site Productivity study areas visited on the field tours. The papers cover subjects on forest harvesting activities, stand establishment, silviculture, site productivity, remote sensing, and wood product technologies.

Book Synopsis Compatible Forest Management by : Robert A. Monserud
Download or read book Compatible Forest Management written by Robert A. Monserud and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 532 pages. Available in PDF, EPUB and Kindle. Book excerpt: Public debate has stimulated interest in finding greater compatibility among forest management regimes. The debate has often portrayed management choices as tradeoffs between biophysical and socioeconomic components of ecosystems. Here we focus on specific management strategies and emphasize broad goals such as biodiversity, wood production and habitat conservation while maintaining other values from forestlands desired by the public. We examine the following proposition: Commodity production (timber, nontimber forest products) and the other forest values (biodiversity, fish and wildlife habitat) can be simultaneously produced from the same area in a socially acceptable manner. Based on recent research in the Pacific Northwest, we show there are alternatives for managing forest ecosystems that avoid the divisive arena of 'either-or' choices. Much of the work discussed in this book addresses two aspects of the compatibility issue. First, how are various forest management practices related to an array of associated goods and services? Second, how do different approaches to forest management affect relatively large and complex ecosystems?
Book Synopsis Methods for Integrated Modeling of Landscape Change by :
Download or read book Methods for Integrated Modeling of Landscape Change written by and published by . This book was released on 2004 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Interior Northwest Landscape Analysis System (INLAS) links a number of resource, disturbance, and landscape simulations models to examine the interactions of vegetative succession, management, and disturbance with policy goals. The effects of natural disturbance like wildfire, herbivory, forest insects and diseases, as well as specific management actions are included. The outputs from simulations illustrate potential changes in aquatic conditions and terrestrial habitat, potential for wood utilization, and socioeconomic opportunities. The 14 chapters of this document outline the current state of knowledge in each of the areas covered by the INLAS project and describe the objectives and organization of the project. The project explores ways to integrate the effects of natural disturbances and management into planning and policy analyses; illustrate potential conflicts among current policies, natural distrubances, and management activities; and explore the policy, economics, and ecological constraints associated with the application of effective fuel treatments on midscale landscapes in the interior Northwest.
Book Synopsis Development of Douglas-fir Log Quality, Product Yield, and Stand Value After Repeated Thinnings in Western Oregon by : Glenn A. Christensen
Download or read book Development of Douglas-fir Log Quality, Product Yield, and Stand Value After Repeated Thinnings in Western Oregon written by Glenn A. Christensen and published by . This book was released on 1997 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forest managers are beginning to take an interest in management of young Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) in Western Oregon and Washington. Studies have established the relationship between growth and levels-of-growing-stock but few have established a link to wood quality and value. This study used data collected from a long term stocking study and established how log quality, product yield, and stand value were affected by repeated early thinnings across a wide range of stand densities. Methods developed by Briggs and Fight (1992) using the ORGANON and TREEVAL computer models to quantify Douglas-fir log quality, product yield and associated dollar value were used. Five thinning densities were considered on plots which are a part of the levels-of-growing-stock (LOGS) cooperative located west of Corvallis in Western Oregon. At stand age 30 all thinning densities consisted of low quality and value log grades. By stand age 50 log quality improved considerably for all treatments. Projections made to stand age 100 show additional improvements in log quality and dollar value. All thinning treatments had a greater proportion of volume in higher quality logs than the unthinned control. Total standing volume was reduced as thinning intensity increased. Gross stand value was found to be highly related to standing board foot volume. By stand age 100 the lightest thinned treatments had the greatest total value and volume. Product yield recovery was found to be fairly consistent between thinning treatments in the mix of lumber grades produced throughout the 80 year analysis period. This was attributed to little change in limb size between treatments and through time. Gross dollar value of lumber produced was found to be highly related to volume yield. The lightest thinned treatments had the greatest standing volume and value in lumber by stand age 100.
