Available in PDF, EPUB and Kindle. Book excerpt: 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.

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.

This book was released on 2008 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nine years after variable-density thinning (VDT) on the Forest Ecosystem Study, we examined low understory vegetation in 60 plots of eight stands (four pairs of VDT and control). We compared native, exotic, ruderal, and nonforest species richness among the stands. We used clustering, ordination, and indicator species analysis to look for distinctive patches of plant associations. Native, exotic, ruderal, and nonforest plant species diversity were higher in VDT stands compared to control stands for both forests. Differentiation of the understory into multiple distinct vegetation patches was not definitive, but there were trends toward greater heterogeneity in VDT stands.

Available in PDF, EPUB and Kindle. Book excerpt: 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?

Available in PDF, EPUB and Kindle. Book excerpt: The conservation of biodiversity has profound implications for managing natural resources with the need for scientific information as a foundation for management decisions increasing dramatically. The_ intent of this book is to look beyond the theory of biodiversity to_ the principles, practices, and policies needed for its conservation. Its objectives are to provide the scientific basis for understanding biodiversity, document case examples of theory and concepts applied at differing scales, and examine policies that affect its conservation.

Download or read book Wildlife and Invertebrate Response to Fuel Reduction Treatments in Dry Coniferous Forests of the Western United States written by David S. Pilliod and published by . This book was released on 2006 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper synthesizes available information on the effects of hazardous fuel reduction treatments on terrestrial wildlife and invertebrates in dry coniferous forest types in the West. We focused on thinning and/or prescribed fire studies in ponderosa pine (Pinus ponderosa) and dry-type Douglas-fir (Pseudotsuga menziesii), lodgepole pine (Pinus contorta), and mixed coniferous forests. Overall, there are tremendous gaps in information needed to evaluate the effects of fuel reduction on the majority of species found in our focal area. Differences among studies in location, fuel treatment type and size, and pre- and post-treatment habitat conditions resulted in variability in species responses. In other words, a species may respond positively to fuel reduction in one situation and negatively in another. Despite these issues, a few patterns did emerge from this synthesis. In general, fire-dependent species, species preferring open habitats, and species that are associated with early successional vegetation or that consume seeds and fruit appear to benefit from fuel reduction activities. In contrast, species that prefer closed-canopy forests or dense understory, and species that are closely associated with those habitat elements that may be removed or consumed by fuel reductions, will likely be negatively affected by fuel reductions. Some habitat loss may persist for only a few months or a few years, such as understory vegetation and litter that recover quickly. The loss of large-diameter snags and down wood, which are important habitat elements for many wildlife and invertebrate species, may take decades to recover and thus represent some of the most important habitat elements to conserve during fuel reduction treatments. Management activities that consider the retention of habitat structures (such as snags, down wood, and refugia of untreated stands) may increase habitat heterogeneity and may benefit the greatest number of species in the long run.

Download or read book Plant Biodiversity written by Abid A Ansari and published by CABI. This book was released on 2016-12-23 with total page 630 pages. Available in PDF, EPUB and Kindle. Book excerpt: Results of regular monitoring of the species diversity and structure of plant communities is used by conservation biologists to help understand impacts of perturbations caused by humans and other environmental factors on ecosystems worldwide. Changes in plant communities can, for example, be a reflection of increased levels of pollution, a response to long-term climate change, or the result of shifts in land-use practices by the human population. This book presents a series of essays on the application of plant biodiversity monitoring and assessment to help prevent species extinction, ecosystem collapse, and solve problems in biodiversity conservation. It has been written by a large international team of researchers and uses case studies and examples from all over the world, and from a broad range of terrestrial and aquatic ecosystems. The book is aimed at any graduate students and researchers with a strong interest in plant biodiversity monitoring and assessment, plant community ecology, biodiversity conservation, and the environmental impacts of human activities on ecosystems.
