Book excerpt: Shelterwood cuttings on Swain Mountain Experimental Forest were measured to determine performance six to eight years after the shelterwood cutting and before shelterwood removal. Use of appropriate selecting criteria minimized windthrow of seed trees. Regeneration remained red fir, even where the major seed source was white fir. Density of seed trees may affect seedling growth only after the fourth year. Adequate regeneration can be attained and maintained at 25 trees per hectare (10/acre). In addition, the total number of seedlings produced each year was apparently not related to cone production in nearby stands.

Available in PDF, EPUB and Kindle. Book excerpt: In a 1964-1967 study on the Challenge Experimental Forest, seedfall was evaluated in 2-, 5-, and 10-acre circular clearcuttings. During the 4 years, 10 seed crops, ranging from light to bumper, were produced by ponderosa pine. white fir, Douglas-fir, and incense cedar. Seedfall ranged from 76 to 40,691 sound seed per acre (188 to 100,547/ha) for a single species in a given year. From 89 to 100 percent of each species' seed fell within an area 1 1/2 times the height of the average dominant tree. Overall, seed distribution was highly variable.

Book excerpt: Research interest in the forests of Oregon and Washington east of the Cascade Range can be traced back to 1897, when Fredrick V. Coville of the Division of Forestry, U.S. Department of Agriculture, reconnoitered the Cascade Range Forest Reserve to report on forest growth and sheep grazing there in an 1898 report. Subsequent forest survey in the late 1890s and early 1900s was stimulated by anticipation of the timber boom that would follow arrival of a railroad. In 1908, Gifford Pinchot's new Forest Service sent young Thornton Taft Munger to study the encroachment of lodgepole pine (Pinus contorta Dougl. ex Loud.) on the more valuable ponderosa pine (Pinus ponderosa Dougl. ex Laws.) stands. By the end of the year, Munger was in charge of the North Pacific District's one-man Section of Silvics, which evolved to become the Pacific Northwest Forest Experiment Station in 1924 with him at the helm. The forest research effort east of the Cascade Range picked up speed with establishment in 1931 of the Pringle Falls Experimental Forest to research the ecologically and economically viable silvicultural systems that would convert the stagnant old-growth forests into more-productive secondgrowth forests. During the ensuing six and one-half decades, a small group of Forest Service researchers and their university counterparts working at the experimental forest and, beginning in 1963, the Bend Silviculture Laboratory, pioneered and pursued the practical silvicultural research that both led and responded to the evolution of their science.

Book Synopsis The Practice of Silviculture by : Mark S. Ashton
Download or read book The Practice of Silviculture written by Mark S. Ashton and published by John Wiley & Sons. This book was released on 2018-03-19 with total page 776 pages. Available in PDF, EPUB and Kindle. Book excerpt: The most up-to-date, comprehensive resource on silviculture that covers the range of topics and issues facing today’s foresters and resource professionals The tenth edition of the classic work, The Practice of Silviculture: Applied Forest Ecology, includes the most current information and the results of research on the many issues that are relevant to forests and forestry. The text covers such timely topics as biofuels and intensive timber production, ecosystem and landscape scale management of public lands, ecosystem services, surface drinking water supplies, urban and community greenspace, forest carbon, fire and climate, and much more. In recent years, silvicultural systems have become more sophisticated and complex in application, particularly with a focus on multi-aged silviculture. There have been paradigm shifts toward managing for more complex structures and age-classes for integrated and complementary values including wildlife, water and open space recreation. Extensively revised and updated, this new edition covers a wide range of topics and challenges relevant to the forester or resource professional today. This full-color text offers the most expansive book on silviculture and: Includes a revised and expanded text with clear language and explanations Covers the many cutting-edge resource issues that are relevant to forests and forestry Contains boxes within each chapter to provide greater detail on particular silvicultural treatments and examples of their use Features a completely updated bibliography plus new photographs, tables and figures The Practice of Silviculture: Applied Forest Ecology, Tenth Edition is an invaluable resource for students and professionals in forestry and natural resource management.

Book Synopsis Regional Silviculture of the United States by : John W. Barrett
Download or read book Regional Silviculture of the United States written by John W. Barrett and published by John Wiley & Sons. This book was released on 1995-02-28 with total page 662 pages. Available in PDF, EPUB and Kindle. Book excerpt: A valuable working resource for professionals. An excellent text for advanced forestry students . . . This unique book provides students and professionals with a broad-based knowledge of contemporary silviculture theory and practice.Throughout, the authors emphasize fundamental questions of edaphic,physiographic, and climatic site factors, as well as ecologicalrelationships and silvical characteristics of major tree species.Updated and expanded to reflect the many scientific, socioeconomic,and public policy trends that have had a profound impact onsilviculture over the past decade, this Third Edition of RegionalSilviculture of the United States: * Brings together the knowledge and expertise of fourteen leadingexperts from around the nation * Provides a rational framework with which to critically assessforest data and to develop innovative silvicultural solutions * Features region-by-region coverage of the eleven major foresttypes in the continental U.S. and Alaska * Offers a detailed look at practices that promote a wide range offorest resources--from wood production and outdoor recreation, towildlife habitat and range forage production * Now includes more in-depth coverage of such crucial themes asbiodiversity, endangered species, habitat fragmentation, foresthealth, landscape management, neotropical migrants, and more "...silviculture is not reducible to a series of rules; it must beflexible and adaptable to a variety of conditions. Much of it is anart as well as a synthesis of ecology and economics. There is nosingle best answer to how a stand should be managed. Andinstitutional and societal constraints must be considered." --fromthe Preface by John W. Barrett Regional Silviculture of the United States, Third Edition is not a"cookbook,"offering pat recipes for solving "typical" silviculturalproblems. Instead, it arms those responsible for the developmentand care of forests with something far more valuable--a rationalframework for the analysis of forest data and the development ofinnovative solutions tailored to specific forest types and theshifting politicoeconomic constraints under which silviculturalistsmust work. One way in which this book achieves that goal is by providingreaders with a broad-based knowledge of contemporary silviculturetheory and practice. In chapters organized according to the elevenmajor forest regions of the continental U.S., fourteen recognizedexperts from around the nation--each of them a specialist in aparticular region of operation--offer their valuable insights andobservations on silviculture in general and on varioussilvicultural practices with which they are familiar. Throughout,the authors are attentive to fundamental considerations of edaphic,physiographic, and climatic site factors, as well as ecologicalrelationships and silvical characteristics of major treespecies. This Third Edition of John W. Barrett's classic has been revisedand expanded to encompass a number of important themes which haverisen to prominence within silviculture over the past decade,including biodiversity, endangered species, habitat fragmentation,forest health, landscape management, and neotropicalmigrants. Timely, authoritative, and comprehensive in scope, RegionalSilviculture of the United States, Third Edition is a valuableresource for foresters, forestry students, ecologists,environmental scientists, and all those concerned with development,management, and preservation of our most valuable nationaltreasure.
