Available in PDF, EPUB and Kindle. Book excerpt: • • • John Harper • • • Nature conservation has changed from an idealistic philosophy to a serious technology. Ecology, the science that underpins the technol ogy of conservation, is still too immature to provide all the wisdom that it must. It is arguable that the desire to conserve nature will in itself force the discipline of ecology to identify fundamental prob lems in its scientific goals and methods. In return, ecologists may be able to offer some insights that make conservation more practicable (Harper 1987). The idea that nature (species or communities) is worth preserv ing rests on several fundamental arguments, particularly the argu ment of nostalgia and the argument of human benefit and need. Nostalgia, of course, is a powerful emotion. With some notable ex ceptions, there is usually a feeling of dismay at a change in the sta tus quo, whether it be the loss of a place in the country for walking or rambling, the loss of a painting or architectural monument, or that one will never again have the chance to see a particular species of bird or plant.

Download or read book Plant Reintroduction in a Changing Climate written by Joyce Maschinski and published by Island Press. This book was released on 2012-03-06 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: Considered an essential conservation tool, plant reintroductions have been conducted for many of the world's rarest plant species. The expertise and knowledge gained through these efforts constitute an essential storehouse of information for conservationists faced with a rapidly changing global climate. This volume presents a comprehensive review of reintroduction projects and practices, the circumstances of their successes or failures, lessons learned, and the potential role for reintroductions in preserving species threatened by climate change. Contributors examine current plant reintroduction practices, from selecting appropriate source material and recipient sites to assessing population demography. The findings culminate in a set of Best Reintroduction Practice Guidelines, included in an appendix. These guidelines cover stages from planning and implementation to long-term monitoring, and offer not only recommended actions but also checklists of questions to consider that are applicable to projects around the world. Traditional reintroduction practice can inform managed relocation-the deliberate movement of species outside their native range-which may be the only hope for some species to persist in a natural environment. Included in the book are discussions of the history, fears, and controversy regarding managed relocation, along with protocols for evaluating invasive risk and proposals for conducting managed relocation of rare plants. Plant Reintroduction in a Changing Climate is a comprehensive and accessible reference for practitioners to use in planning and executing rare plant reintroductions.

Download or read book Wildflowers of the Columbia Gorge written by and published by University of Washington Press. This book was released on 1988 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: As it sweeps through the Cascade Mountains, the Columbia River passes through an area of jagged cliffs and tumbling waterfalls--the Columbia Gorge. This Gorge, with its wide range of elevations and microclimates, is home to more species of flowering plants than any other region in the Pacific Northwest. Compiled by author and photographer Russ Jolley, this remarkable guide contains 744 of these plants. Each full-color photograph is accompanied by and entry listing the wildflower's common and scientific names, general habitat, blooming dates, and specific plant locations. To make the wildflowers easier to find, all blooming locations are within easy walking distance of roads and trailheads. Jolley also describes a series of field trips for readers unfamiliar with this area. Included, too, are a fold-out map of the Gorge, a convenient list of place names, and a table of blooming dates for all 744 flowering plants.

Available in PDF, EPUB and Kindle. Book excerpt: As the human impact on the earth leads to ever increasing environmental degradation, the restoration of dwindling populations of numerous plant and animal species has become urgent. In this volume, contributors examine the conceptual, planning, and applied aspects of recovery of rare or endangered species. It is unique in its treatment of both plants and animals, and in its presentation of scientific approaches to implemented restorations. Experts report on the restoration efforts and plans for the restoration of a wide variety of species including the dune thistle, lakeside daisy, woodland caribou, kit fox, and black-footed ferret and end with a broad overview, suggesting future opportunities and problems.
Download or read book Restoring Diversity written by Donald A. Falk and published by . This book was released on 1996 with total page 536 pages. Available in PDF, EPUB and Kindle. Book excerpt: The reintroduction of rare and endangered species to their natural habitat is one of emerging tools of ecosystem management. Yet despite hundreds of ongoing projects, the biological underpinnings of such activity are poorly understood, and important questions remain. Restoring Diversity provides biological, policy, and regulatory foundations for successful restoration of rare plants. Topics considered include the strategic and legal context for rare plant restoration, the biology of restoration, use (and misuse) of mitigation in rare plant conservation, and case studies from across the United States. Restoring Diversity presents model guidelines for the reintroduction of endangered plants - guidelines that incorporate ideas contained in the book's chapters with the wide-ranging experience of experts in the field. It is a pathbreaking work that not only unifies concepts in the field of restoration, but also fills significant technical and policy gaps and provides operational tools for successful restorations.

Available in PDF, EPUB and Kindle. Book excerpt: A sophisticated ecological analysis of ranching in northern Nevada featuring a new chapter and new epilogue by the authors.First published in 1985, Cattle in the Cold Desert has become a classic in the environmental history of the Great Basin, brilliantly combining a lively account of the development of the Great Basin grazing industry with a detailed scientific discussion of the ecology of its sagebrush/grassland plant communities. The volume traces the history of white settlement in the Great Basin from about 1860, along with the arrival of herds of cattle and sheep to exploit the forage resources of a pristine environment and, through the history of John Sparks, a pioneer cattleman, illustrates how the herdsmen interacted with the sagebrush/grasslands of the cold desert West. As the story unfolds on two levels—that of the herdsmen adapting their livelihood to the challenging conditions of the Great Basin's scanty forage, aridity, and fierce winters, and that of the fragile ecology of the desert plant communities responding to the presence of huge herds of livestock—we see the results of a grand experiment initiated by men willing to venture beyond the limits of accepted environmental potential to settle the Great Basin, as well as the often ruinous consequences of the introduction of domestic livestock into the plant communities of the region. The result is a remarkably balanced and insightful discussion of the grazing industry in the Intermountain West. This new paperback edition includes an additional chapter that addresses the impact of wild mustangs on the Great Basin rangelands, and an epilogue that discusses changes in rangeland management and in rangeland conditions, especially the impact of recent wildfires. As concern over the future of the Great Basin's unique rangeland environment and its principal agricultural industry grows, Cattle in the Cold Desert remains essential reading for everyone who cares about this underappreciated region of the American West.
