Book Synopsis National Capacity in Forestry Research by : National Research Council
Download or read book National Capacity in Forestry Research written by National Research Council. This book was released on 2002-06-21. Available in PDF, EPUB and Kindle. Book excerpt: Forests are major components of the earth's natural resources and they are increasingly critical to the welfare of the U.S. economy, environment, and population. Desires to improve forest management and productivity, preserve biodiversity, maintain ecologic integrity, and provide societal services, such as recreation and tourism, necessitate a strong forestry-research base. Given the clear importance of forestry research in sustaining forests for the future, the U.S. Department of Agriculture (USDA) Forest Service asked the Board on Agriculture and Natural Resources of the National Academies to undertake a study of the nation's capacity in forestry research. The Committee on National Capacity in Forestry Research was appointed to carry out the study, which was conducted to review the current expertise and status of forestry research and to examine the approaches of natural resources education and forestry-research organizations to meet future needs.

Book Synopsis Modelling Forest Development by : Klaus von Gadow
Download or read book Modelling Forest Development written by Klaus von Gadow. This book was released on 2001-11-30. Available in PDF, EPUB and Kindle. Book excerpt: The key to successful timber management is a proper understanding of growth processes, and one of the objectives of modelling forest development is to provide the tools that enable foresters to compare alternative silvicultural treatments. In a managed woodland, the most important periodic disturbances are the thinning operations, which are often carried out at regular intervals and which usually have a significant effect on the future evolution of the resource. Thus, a realistic model of forest development includes both natural growth and thinnings. One of the outstanding features of this book is its inclusion of thinning models at varying levels of resolution and consideration of differences in foresters' tree marking behaviour. Other interesting aspects include regional resource forecasting approaches, generalized stem taper functions, generalized diameter-height relations, new ways of describing and reproducing forest spatial structures, crown modelling and iterative competition modelling. Worked examples and code are provided where appropriate. The intended readership is graduate students.

Book Synopsis Forests on the Edge by :
Download or read book Forests on the Edge written by . This book was released on 2005. Available in PDF, EPUB and Kindle. Book excerpt: The private working land base of America's forests is being converted to developed uses, with implications for the condition and management of affected private forests and the watersheds in which they occur. The Forests on the Edge project seeks to improve understanding of the processes and thresholds associated with increases in housing density in private forests and likely effects on the contributions of those forests to timber, wildlife, and water resources. This report, the first in a series, displays and describes housing density projections on private forests, by watershed, across the conterminous United States. An interdisciplinary team used geographic information system (GIS) techniques to identify fourth-level watersheds containing private forests that are projected to experience increased housing density by 2030. Results indicate that some 44.2 million acres (over 11 percent) of private forests--particularly in the East, where most private forests occur--are likely to see dramatic increases in housing development in the next three decades, with consequent impacts on ecological, economic, and social services. Although conversion of forest land to other uses over time is inevitable, local jurisdictions and states can target efforts to prevent or reduce conversion of the most valuable forest lands to keep private working forests resilient and productive.

Book Synopsis Forest Service Research and Development by : Anu K. Mittal
Download or read book Forest Service Research and Development written by Anu K. Mittal. This book was released on 2011-05. Available in PDF, EPUB and Kindle. Book excerpt: In recent decades, managing the nation's public and private forests and rangelands has become increasingly complex, requiring a sound understanding of science and science-based tools to address these complexities. The Forest Service (FS) maintains a research and development program (FS R&D) to help provide scientific info. and tools. This report examined: (1) the scope of R&D carried out by FS R&D and some of its resulting accomplishments; (2) trends in resources used in performing FS R&D work and the effects of those trends on its research efforts and priorities; and (3) recent steps FS R&D has taken to improve its ability to fulfill its mission and challenges it faces in doing so. Illus. This is a print on demand report.
