Available in PDF, EPUB and Kindle. Book excerpt: The discipline of silviculture is at a crossroads. Silviculturists are under increasing pressure to develop practices that sustain the full function and dynamics of forested ecosystems and maintain ecosystem diversity and resilience while still providing needed wood products. A Critique of Silviculture offers a penetrating look at the current state of the field and provides suggestions for its future development. The book includes an overview of the historical developments of silvicultural techniques and describes how these developments are best understood in their contemporary philosophical, social, and ecological contexts. It also explains how the traditional strengths of silviculture are becoming limitations as society demands a varied set of benefits from forests and as we learn more about the importance of diversity on ecosystem functions and processes. The authors go on to explain how other fields, specifically ecology and complexity science, have developed in attempts to understand the diversity of nature and the variability and heterogeneity of ecosystems. The authors suggest that ideas and approaches from these fields could offer a road map to a new philosophical and practical approach that endorses managing forests as complex adaptive systems. A Critique of Silviculture bridges a gap between silviculture and ecology that has long hindered the adoption of new ideas. It breaks the mold of disciplinary thinking by directly linking new ideas and findings in ecology and complexity science to the field of silviculture. This is a critically important book that is essential reading for anyone involved with forest ecology, forestry, silviculture, or the management of forested ecosystems.

Book excerpt: This publication provides highlights of forest inventories and surveys from 1993 to 2001. About 35 percent of eastern Oregon is forested. The amount of forest land in eastern Oregon has increased by about 650,000 acres from the 1930s, with increases in juniper forest land accounting for most of the change. Thirty-one tree species were tallied in forest inventories during the 1990s, with ponderosa pine the predominant species in all ecological provinces in eastern Oregon. The Forest Service, Bureau of Land Management, and other federal agencies manage about 71 percent of eastern Oregon forests; about 27 percent is privately owned; and the remaining 2 percent is managed by the Oregon Department of Forestry and other nonfederal public agencies. The volume of wood in eastern Oregon forests is about 25.7 billion cubic feet, of which about 312 million cubic feet per year were harvested between 1987 and 1999. In the same time period, annual mortality and removals exceeded annual growth for all ownerships. Down wood is an important forest component and shows increases with forest age. Insect defoliators, bark beetles, root diseases, and dwarf mistletoes are present on over 72 percent of forest land in eastern Oregon. Year-to-year defoliation or mortality trends can be detected with aerial surveys. Introduced plant species are present on over 50 percent of private and other public forest land. Diversity of lichens (indicators of air pollution, climate, and forest age and structure) is greatest in the Blue Mountains Province and lowest in the Intermountain Province. No ozone injury has been detected on sensitive forest trees and plant species in eastern Oregon.

Available in PDF, EPUB and Kindle. Book excerpt: Many terms often used to describe old-growth forests imply that these forests are less vigorous, less productive and less stable than younger forests. But research in the last two decades has yielded results that challenge the view of old-growth forests being in decline. Given the importance of forests in battling climate change and the fact that old-growth forests are shrinking at a rate of 0.5% per year, these new results have come not a moment too soon. This book is the first ever to focus on the ecosystem functioning of old-growth forests. It is an exhaustive compendium of information that contains original work conducted by the authors. In addition, it is truly global in scope as it studies boreal forests in Canada, temperate old-growth forests in Europe and the Americas, and global tropical forests. Written in part to affect future policy, this eminently readable book is as useful for the scientist and student as it is for the politician and politically-interested layman.

Book excerpt: In the past decade, there has been much debate over the environmental impact of forestry. People are justifiably concerned about what is happening to the local and global forest environments, but they are also confused by the polarized rhetoric that has characterized both sides of the debate. In Balancing Act, Hamish Kimmins calls for a balanced, more objective approach to forestry issues in order to bridge the gap between the most extreme opponents in the debate. He suggests that we need to begin with a common understanding of what forestry is about and how forest ecosystems work. He outlines the scientific and ecological aspects of the major environmental issues facing British Columbia and the world today, arguing that we need to disentangle the scientific from the value-based social aspects of these questions. He also contends that much of the current debate about forests and their management ignores the time dimension of ecosystems, and he calls for a more dynamic view of current environmental issues in forestry -- one that accounts for change. The first few chapters provide an outline of the basic principles of forestry and ecology, and subsequent chapters discuss the major environmental issues facing forestry in the 1990s. These include clearcutting, slashburning, management chemicals, old growth, biological diversity, 'new forestry, ' climate change, acid rain, the comparison between temperate and tropical forestry, and long-term decisions in forestry. Balancing Act is essential reading for those who are searching for an objective, accurate, and readable evaluation of the issues at the heart of the forestry/environment debate. By emphasizing that forests are not static but change over time, Kimmins adds an important, often ignored, dimension to the discussion. Only by understanding all the intricacies of the ecosystems can we learn to manage our forests in a sustainable fashion.

Available in PDF, EPUB and Kindle. Book excerpt: Forests are an important component in the visual appeal of landscapes. There is an increasing recognition of the importance of this subject among foresters and environmental scientists. Increasingly, forest resource managers must consider the aesthetic consequences of timber harvesting operations and management plans. This book is the first to address this subject area. It consists of 15 chapters and is divided into four parts. It brings together not only foresters and ecologists, but also landscape architects, psychologists and philosophers. It should therefore attract a wide readership. Contributors are leading research workers in their subjects, from Canada, the USA and UK.

Available in PDF, EPUB and Kindle. Book excerpt: Old-growth forests represent a lofty ideal as much as an ecosystem—an icon of unspoiled nature, ecological stability, and pristine habitat. These iconic notions have actively altered the way society relates to old-growth forests, catalyzing major changes in policy and management. But how appropriate are those changes and how well do they really serve in reaching conservation goals? Old Growth in a New World untangles the complexities of the old growth concept and the parallel complexity of old-growth policy and management. It brings together more than two dozen contributors—ecologists, economists, sociologists, managers, historians, silviculturists, environmentalists, timber producers, and philosophers—to offer a broad suite of perspectives on changes that have occurred in the valuing and management of old-growth forests in the Pacific Northwest over the past thirty years. The book • introduces the issues and history of old-growth values and conservation in the Pacific Northwest; • explores old growth through the ideas of leading ecologists and social scientists; • addresses the implications for the future management of old-growth forests and considers how evolving science and social knowledge might be used to increase conservation effectiveness. By confronting the complexity of the old-growth concept and associated policy and management challenges, Old Growth in a New World encourages productive discussion on the future of old growth in the Pacific Northwest and offers options for more effective approaches to conserving forest biodiversity.

The book will therefore appeal to a wide readership of aquatic ecologists and foresters, both professional and amateur alike". Scottish Forestry Royal Scottish Forestry Society"...the book makes a very significant contribution to our growing awareness of the ecological importance of driftwood. This contribution is founded on two particular aspects of the book: the writing style, which is clear and directed very much at the general reader; and the scope of the book, which is very broad and, to my knowledge, goes far beyond other reviews of the topic".

Available in PDF, EPUB and Kindle. Book excerpt: The North Pacific temperate rainforest, stretching from southern Alaska to northern California, is the largest temperate rainforest on earth. This book provides a multidisciplinary overview of key issues important for the management and conservation of the northern portion of this rainforest, located in northern British Columbia and southeastern Alaska. This region encompasses thousands of islands and millions of acres of relatively pristine rainforest, providing an opportunity to compare the ecological functioning of a largely intact forest ecosystem with the highly modified ecosystems that typify most of the world's temperate zone. The book examines the basic processes that drive the dynamic behavior of such ecosystems and considers how managers can use that knowledge to sustainably manage the rainforest and balance ecosystem integrity with human use. Together, the contributors offer a broad understanding of the challenges and opportunities faced by scientists, managers, and conservationists in the northern portion of the North Pacific rainforest that will be of interest to conservation practitioners seeking to balance economic sustainability and biodiversity conservation across the globe. Gordon Orians is professor emeritus of biology at the University of Washington. John Schoen is a senior science advisor at Audubon Alaska.
