Book Description
This report provides carbon storage and flux estimates for the two national forests in Alaska using inventory data from permanent plots established in 1995-2003 and remeasured in 2004-2010. Estimates of change are reported separately for growth, sapling recruitment, harvest, mortality, snag recruitment, salvage, snag falldown, and decay. Although overall aboveground carbon mass in live trees did not change in the Tongass National Forest, the Chugach National Forest showed a 4.5% increase. For the Tongass National Forest, results differed substantially for managed and unmanaged forest: managed lands had higher per-acre rates of sequestration through growth and recruitment, and carbon stores per acre that were higher for decomposing downed wood, and lower for live trees and snags. The species composition of carbon stores is changing on managed lands, with a carbon mass loss for yellow-cedar but increases for red alder and Sitka spruce. On unmanaged lands, the Chugach National forest had carbon mass increases in Sitka spruce and white spruce, and the Tongass National Forest had increases in western red cedar and red alder. Figures and tables. This is a print on demand report.

Book Description
Tongass Odyssey is a biologist’s memoir of personal experiences over the past four decades studying brown bears, deer, and mountain goats and advocating for conservation of Alaska’s Tongass National Forest. The largest national forest in the nation, the Tongass encompasses the most significant expanse of intact old-growth temperate rainforest remaining on Earth. Tongass Odyssey is a cautionary tale of the harm that can result when science is eclipsed by politics that are focused on short-term economic gain. Yet even as those problems put the Tongass at risk, the forest also represents a unique opportunity for conserving large, intact landscapes with all their ecological parts, including wild salmon, bears, wolves, eagles, and other wildlife. Combining elements of personal memoir, field journal, natural history, conservation essay, and philosophical reflection, Tongass Odyssey tells an engaging story about an enchanting place.

Book Description
In recent years, conflicts between ecological conservation and economic growth forced a reassessment of the motivations and goals of wildlife and forestry management. Focus shifted from game and commodity management to biodiversity conservation and ecological forestry. Previously separate fields such as forestry, biology, botany, and zoology merged

Book Description
'At last a really useful book telling us how all the rhetoric about ecosystem approaches and sustainable forest management is being translated into practical solutions on the ground? CLAUDE MARTIN, WWF INTERNATIONAL For too long, foresters have seen forests as logs waiting to be turned into something useful. This book demonstrates that forests in fact have multiple values, and managing them as ecosystems will bring more benefits to a greater cross-section of the public? JEFFREY A. MCNEELY, CHIEF SCIENTIST, IUCN This book demonstrates that ecosystem approaches and sustainable forest management] are neither alternative methods of forest management nor are they simply complicated ways of saying the same thing. They are both emerging concepts for more integrated and holistic ways of managing forests within larger landscapes in ways that optimize benefits to all stakeholders? ACHIM STEINER AND IAN JOHNSON, FROM THE FOREWORD Recent innovations in Sustainable Forest Management and Ecosystem Approaches are resulting in forests increasingly being managed as part of the broader social-ecological systems in which they exist. Forests in Landscapes reviews changes that have occurred in forest management in recent decades. Case studies from Europe, Canada, the United States, Russia, Australia, the Congo and Central America provide a wealth of international examples of innovative practices. Cross-cutting chapters examine the political ecology and economics of forest management, and review the information needs and the use and misuse of criteria and indicators to achieve broad societal goals for forests. A concluding chapter draws out the key lessons of changes in forest management in recent decades and sets out some thoughts for the future. This book is a must-read for practitioners, researchers and policy makers concerned with forests and land use. It contains lessons for all those concerned with forests as sources of people's livelihoods and as part of rural landscapes. Published with IUCN and PROFOR

Book Description
Salvage logging—removing trees from a forested area in the wake of a catastrophic event such as a wildfire or hurricane—is highly controversial. Policymakers and those with an economic interest in harvesting trees typically argue that damaged areas should be logged so as to avoid “wasting” resources, while many forest ecologists contend that removing trees following a disturbance is harmful to a variety of forest species and can interfere with the natural process of ecosystem recovery. Salvage Logging and Its Ecological Consequences brings together three leading experts on forest ecology to explore a wide range of issues surrounding the practice of salvage logging. They gather and synthesize the latest research and information about its economic and ecological costs and benefits, and consider the impacts of salvage logging on ecosystem processes and biodiversity. The book examines • what salvage logging is and why it is controversial • natural and human disturbance regimes in forested ecosystems • differences between salvage harvesting and traditional timber harvesting • scientifically documented ecological impacts of salvage operations • the importance of land management objectives in determining appropriate post-disturbance interventions Brief case studies from around the world highlight a variety of projects, including operations that have followed wildfires, storms, volcanic eruptions, and insect infestations. In the final chapter, the authors discuss policy management implications and offer prescriptions for mitigating the impacts of future salvage harvesting efforts. Salvage Logging and Its Ecological Consequences is a “must-read” volume for policymakers, students, academics, practitioners, and professionals involved in all aspects of forest management, natural resource planning, and forest conservation.

Book Description
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 Description
The Ecological Importance of High-Severity Fires, presents information on the current paradigm shift in the way people think about wildfire and ecosystems. While much of the current forest management in fire-adapted ecosystems, especially forests, is focused on fire prevention and suppression, little has been reported on the ecological role of fire, and nothing has been presented on the importance of high-severity fire with regards to the maintenance of native biodiversity and fire-dependent ecosystems and species. This text fills that void, providing a comprehensive reference for documenting and synthesizing fire's ecological role. - Offers the first reference written on mixed- and high-severity fires and their relevance for biodiversity - Contains a broad synthesis of the ecology of mixed- and high-severity fires covering such topics as vegetation, birds, mammals, insects, aquatics, and management actions - Explores the conservation vs. public controversy issues around megafires in a rapidly warming world
