The Pacific Northwest is a global ecological "hotspot" because of its relatively healthy native ecosystems, a high degree of biodiversity, and the number and scope of restoration initiatives that have been undertaken there. Restoring the Pacific Northwest gathers and presents the best examples of state-of-the-art restoration techniques and projects. It is an encyclopedic overview that will be an invaluable reference not just for restorationists and students working in the Pacific Northwest, but for practitioners across North America and around the world.

Since adoption of the Northwest Forest Plan (NWFP) in the early 1990s, there has been a fundamental shift in forest management practices on federal lands in western Oregon and Washington. Commoditydriven clearcut regeneration harvests have given way to thinnings intended to enhance development of late-successional forest habitats and to conserve important aquatic and riparian ecosystems. Density Management in the 21st Century: West Side Story presents abstracts and peer reviewed papers from a regional conference highlighting more than twenty years of research related to forest thinning in the NWFP area. Presentations from the BLM Density Management and Riparian Buffer Study provide a focal point, with presentations from additional studies providing for a more complete overview of the west-side thinning science. The contributions are organized as five topical themes: The Regional and Landscape Context for Density Management in the Northwest Forest Plan Era; Implementation and Influences of Density Management in the Terrestrial Ecosystem; Riparian and Aquatic Ecosystems and their Responses to Thinning and Buffers; Socioeconomics and Operations; and Thinning and Adaptation. Collectively, the contributions summarize many important forest dynamics and ecosystem responses to partial overstory removals. Interactions between aquatic and riparian ecosystem conservation measures and upland harvest are emphasized. Targeting resource management practitioners, decision-makers and researchers, the collected works provide a reference to the current and future roles and issues of density management as a tool for forest ecosystem management.

"A primary mission of the U.S. Department of Agriculture Forest Service is multiple resource management, and one of the emerging themes is forest restoration. The National Silviculture Workshop, a biennial event co-sponsored by the Forest Service, was held May 7-10, 2007, in Ketchikan, Alaska, with the theme of "Integrated Restoration of Forested Ecosystems to Achieve Multiresource Benefits." This proceedings presents a compilation of state-of-the-art silvicultural research and forestry management papers that demonstrates integrated restoration to yield multiple resource benefits. These papers highlight national perspectives on ecosystem services, forest restoration and climate change, and regional perspectives on forest restoration and silvicultural practices to achieve multiple resource benefits from researchers and forest practitioners working in a broad array of forest types in the United States."

Public debate has stimulated interest in finding greater compatibility among forest management regimes. The debate has often portrayed management choices as tradeoffs between biophysical and socioeconomic components of ecosystems. Here we focus on specific management strategies and emphasize broad goals such as biodiversity, wood production and habitat conservation while maintaining other values from forestlands desired by the public. We examine the following proposition: Commodity production (timber, nontimber forest products) and the other forest values (biodiversity, fish and wildlife habitat) can be simultaneously produced from the same area in a socially acceptable manner. Based on recent research in the Pacific Northwest, we show there are alternatives for managing forest ecosystems that avoid the divisive arena of 'either-or' choices. Much of the work discussed in this book addresses two aspects of the compatibility issue. First, how are various forest management practices related to an array of associated goods and services? Second, how do different approaches to forest management affect relatively large and complex ecosystems?

Researchers involved with the Pacific Northwest (PNW) Research Station Sustainable Wood Production Initiative have outlined some of the barriers and opportunities for sustainable wood production in the region. Sustainable wood production is defined as the capacity of forests to produce wood, products, and services on a long-term basis and in the context of human activity and use. The collective findings of these papers suggest that in the future, the regions wood supply will primarily come from private land, and the barriers and opportunities related to sustainable wood production will have more to do with future markets, harvest potential, land use changes, and sustainable forestry options than with traditional sustained yield outputs. Private lands in the PNW should be able to sustain recent historical harvest levels over the next 50 years, but regional changes in sawmilling capacity and uncertain market conditions may affect wood production in the region. Public perceptions of forestry, land use changes, and alternative forestry options are also discussed. These papers present preliminary findings and proposals for future work designed to help us understand the key issues related to sustainable wood production.

Silvicultural practices in the Douglas-fir region evolved through a combination of formal research, observation, and practical experience of forest managers and silviculturists, and changing economic and social factors. This process began more than a century ago and still continues. It has had a great influence on the economic well-being of the region and on the present characteristics of the regions forests. This long history is unknown to most of the public, and much of it is unfamiliar to many natural resource specialists outside (and even within) the field of silviculture. We trace the history of how we got where we are today and the contribution of silvicultural research to the evolution of forest practices. We give special attention to the large body of information developed in the first half of the past century that is becoming increasingly unfamiliar to both operational foresters andperhaps more importantlyto those engaged in forestry research. We also discuss some current trends in silviculture and silviculture-related research.

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.
