This book was released on 1996 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: Density manipulation is one of the most powerful tools available to silviculturists to achieve a broad range of silvicultural objectives. One of the most effective methods of planning density management in even-aged stands is through the use of stand density management diagrams. These diagrams graphically depict the temporal relationships between stand density, top height, quadratic mean diameter and mean tree volume. They allow the user to develop and project crop plans through time, to determine the optimum timing of thinnings, to determine the operational feasibility of thinnings, and to contrast potential outcomes from a number of stand management regimes. The stand density management diagrams for lodgepole pine, white spruce and interior Douglas-fir in this report were derived from managed stand yield tables produced by TASS, an individual tree, distance-dependent growth model. The report describes their use in planning thinning regimes and making preliminary yield estimations.

Book excerpt: "This book presents a synthesis of published information on mountain pine beetle (Dendroctonus ponderosae Hopkins [Coleoptera: Scolytidae]) biology and management with an emphasis on lodgepole pine (Pinus contorta Dougl. ex Loud. var. latifolia Engelm.) forests of western Canada. Intended as a reference for researchers as well as forest managers, the book covers three main subject areas: mountain pine beetle biology, management, and socioeconomic concerns. The chapters on biology cover taxonomy, life history and habits, distribution, insect-host tree interactions, development and survival, epidemiology, and outbreak history. The management section covers management strategy, survey and detection, proactive and preventive management, and decision support tools. The chapters on socioeconomic aspects include an economic examination of management programs and the utilization of post-beetle salvage timber in solid wood, panelboard, pulp and paper products."--Publisher's description.

Book excerpt: “One of the most profound and illuminating studies of this century to have been published in recent decades.”—John Gray, New York Times Book Review Hailed as “a magisterial critique of top-down social planning” by the New York Times, this essential work analyzes disasters from Russia to Tanzania to uncover why states so often fail—sometimes catastrophically—in grand efforts to engineer their society or their environment, and uncovers the conditions common to all such planning disasters. “Beautifully written, this book calls into sharp relief the nature of the world we now inhabit.”—New Yorker “A tour de force.”— Charles Tilly, Columbia University
Download or read book Stepping Back to Look Forward written by Charles H. W. Foster and published by Harvard University Forest. This book was released on 1998 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: This timely collection of essays - written by nine recognized forestry and environmental specialists - tells the story of the conservation, use, and changes in the Commonwealth's forests over time. The book traces the development of pre-settlement, colonial, and post-Revolutionary War forest practices, and concludes with recommendations as to how history might be used to inform and shape future policy. Underscored is the importance of private and local leadership, such as the unique Massachusetts town forest movement. Economic contributions and educational programs are detailed, as well as the ways Massachusetts' leadership has influenced national forestry. Written for the layperson, and reflecting the particular experience and style of each contributor, the history will appeal to a range of readers from local conservation activists to forestry professionals and policymakers.

Download or read book Silviculture written by Ralph D. Nyland and published by Waveland Press. This book was released on 2016-05-13 with total page 680 pages. Available in PDF, EPUB and Kindle. Book excerpt: Silviculture: Concepts and Applications reflects a belief that all the tools of silviculture have a useful role in modern forestry. Through careful analysis and creative planning, foresters can address a wide array of commodity and nonmarket interests and opportunities while maintaining dynamic and resilient forests. A landowner’s needs, circumstances, and site conditions guide a silviculturist’s judgment and decision making in finding the best ways to integrate the biologic-ecologic, economic-financial, and managerial-administrative requirements at hand. The Third Edition of this influential text provides a foundational basis for rigorous discussion of techniques. The inclusion of numerous real-world examples and balanced coverage of past and current practices broadens the concept of silviculture and the ways that managers can use it to address both traditional and emerging interests in forests. A thorough discussion of new and proven interpretations increasingly directs the attention of foresters toward the role silviculture plays in creating, maintaining, rehabilitating, and restoring forests that can sustain an expanding variety of ecosystem services.

Available in PDF, EPUB and Kindle. Book excerpt: The Clean Water Act (CWA) requires that wetlands be protected from degradation because of their important ecological functions including maintenance of high water quality and provision of fish and wildlife habitat. However, this protection generally does not encompass riparian areasâ€"the lands bordering rivers and lakesâ€"even though they often provide the same functions as wetlands. Growing recognition of the similarities in wetland and riparian area functioning and the differences in their legal protection led the NRC in 1999 to undertake a study of riparian areas, which has culminated in Riparian Areas: Functioning and Strategies for Management. The report is intended to heighten awareness of riparian areas commensurate with their ecological and societal values. The primary conclusion is that, because riparian areas perform a disproportionate number of biological and physical functions on a unit area basis, restoration of riparian functions along America's waterbodies should be a national goal.
