Download or read book Reforestation Trials and Secondary Succession with Three Levels of Overstory Shade in the Grand Fir Mosaic Ecosystem written by Dennis E. Ferguson and published by . This book was released on 2005 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Grand Fir Mosaic habitats are difficult to regenerate because of pocket gophers (Thomomys talpoides) and successional plant communities dominated by bracken fern (Pteridium aquilinum) and western coneflower (Rudbeckia occidentalis). This study tested reforestation practices recommended by previous research, tested hypotheses about the effects of overstory shade on regeneration success, and documented secondary succession. Natural regeneration is not a reliable reforestation method on Grand Fir Mosaic sites. Clearcut and planting was the best regeneration method if pocket gophers are controlled. Partial cutting and planting was the best regeneration method if pocket gophers were not controlled. Most gopher-caused seedling mortality occurred the first summer, first winter, and second winter after planting. The clearcut treatment resulted in the loss of shrub species and the dominance of bracken fern and/or western coneflower. In the partial cut treatment, shrubs were retained and there was less bracken fern and/or western coneflower than in the clearcut treatment.

Book excerpt: That is what this book is about. It is a framework for planning, in which habitat is the key to managing wildlife and making forest managers accountable for their actions. This book is based on the collective knowledge of one group of resource professionals and their understanding about how wildlife relate to forest habitats. And it provides a longoverdue system for considering the impacts of changes in forest structure on all resident wildlife.

Download or read book Wildlife habitat Relationships in Oregon and Washington written by David H. Johnson and published by . This book was released on 2001 with total page 764 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume provides information about the terrestrial, freshwater, and marine habitats of Oregon and Washington and the wildlife that depend upon them; it also supports broader and more consistent conservation planning, management, and research. The 27 chapters identify 593 wildlife species, define some 300 wildlife terms, profile wildlife communities, review introduced and extirpated species and species at risk, and discuss management approaches. The volume includes color and bandw photographs, maps, diagrams, and illustrations; and the accompanying CD-ROM contains additional wildlife data (60,000 records), maps, and seven matrixes that link wildlife species with their respective habitat types. Johnson is a wildlife biologist, engineer, and habitat scientist; and O'Neill is director of the Northwest Habitat Institute; they worked together on this publication project as its managing directors.

Available in PDF, EPUB and Kindle. Book excerpt: How can environmental degradation be stopped? How can it be reversed? And how can the damage already done be repaired? The authors of this volume argue that a two-pronged approach is needed: reducing demand for ecosystem goods and services and better management of them, coupled with an increase in supply through environmental restoration. Restoring Natural Capital brings together economists and ecologists, theoreticians, practitioners, policy makers, and scientists from the developed and developing worlds to consider the costs and benefits of repairing ecosystem goods and services in natural and socioecological systems. It examines the business and practice of restoring natural capital, and seeks to establish common ground between economists and ecologists with respect to the restoration of degraded ecosystems and landscapes and the still broader task of restoring natural capital. The book focuses on developing strategies that can achieve the best outcomes in the shortest amount of time as it: • considers conceptual and theoretical issues from both an economic and ecological perspective • examines specific strategies to foster the restoration of natural capital and offers a synthesis and a vision of the way forward Nineteen case studies from around the world illustrate challenges and achievements in setting targets, refining approaches to finding and implementing restoration projects, and using restoration of natural capital as an economic opportunity. Throughout, contributors make the case that the restoration of natural capital requires close collaboration among scientists from across disciplines as well as local people, and when successfully executed represents a practical, realistic, and essential tool for achieving lasting sustainable development.
Download or read book Stream Ecology written by J. David Allan and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: Running waters are enormously diverse, ranging from torrential mountain brooks, to large lowland rivers, to great river systems whose basins occupy subcontinents. While this diversity makes river ecosystems seem overwhelmingly complex, a central theme of this volume is that the processes acting in running waters are general, although the settings are often unique. The past two decades have seen major advances in our knowledge of the ecology of streams and rivers. New paradigms have emerged, such as the river continuum and nutrient spiraling. Community ecologists have made impressive advances in documenting the occurrence of species interactions. The importance of physical processes in rivers has attracted increased attention, particularly the areas of hydrology and geomorphology, and the inter-relationships between physical and biological factors have become better understood. And as is true for every area of ecology during the closing years of the twentieth century it has become apparent that the study of streams and rivers cannot be carried out by excluding the role of human activities, nor can we ignore the urgency of the need for conservation. These developments are brought together in Stream Ecology: Structure and function of running waters, designed to serve as a text for advanced undergraduate and graduate students, and as a reference book for specialists in stream ecology and related fields.
