Download or read book Landscape Permeability for Large Carnivores in Washington written by Peter H. Singleton and published by . This book was released on 2002 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: We conducted a regional-scale evaluation of landscape permeability for large carnivores in Washington and adjacent portions of British Columbia and Idaho. We developed geographic information system based landscape permeability models for wolves (Canis lupus), wolverine (Gulo gulo), lynx (Lynx canadensis), and grizzly bear (Ursus arctos). We also developed a general large carnivore model to provide a single generalization of the predominant landscape patterns for the four focal species. The models evaluated land cover type, road density, human population density, elevation, and slope to provide an estimate of landscape permeability. We identified five concentrations of large carnivore habitat between which we evaluated landscape permeability. The habitat concentration areas were the southern Cascade Range, the north-central Cascade Range, the Coast Range, the Kettle-Monashee Ranges, and the Selkirk-Columbia Mountains. We evaluated landscape permeability in fracture zones between these areas, including the I-90 Snoqualmie Pass area, the Fraser-Coquihalla area, the Okanogan Valley, and the upper Columbia and Pend Oreille River valleys. We identified the portions of the Washington state highway system that passed through habitat linkages between the habitat concentration areas and areas accessible to the focal species. This analysis provides a consistent measure of estimated landscape permeability across the analysis area, which can be used to develop conservation strategies, contribute to future field survey efforts, and help identify management priorities for the focal species.

Download or read book Connectivity Conservation written by Kevin R. Crooks and published by Cambridge University Press. This book was released on 2006-11-02 with total page 675 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the biggest threats to the survival of many plant and animal species is the destruction or fragmentation of their natural habitats. The conservation of landscape connections, where animals, plants, and ecological processes can move freely from one habitat to another, is therefore an essential part of any new conservation or environmental protection plan. In practice, however, maintaining, creating, and protecting connectivity in our increasingly dissected world is a daunting challenge. This fascinating volume provides a synthesis on the current status and literature of connectivity conservation research and implementation. It shows the challenges involved in applying existing knowledge to real-world examples and highlights areas in need of further study. Containing contributions from leading scientists and practitioners, this topical and thought-provoking volume will be essential reading for graduate students, researchers, and practitioners working in conservation biology and natural resource management.
Download or read book Key Topics in Conservation Biology 2 written by David W. Macdonald and published by John Wiley & Sons. This book was released on 2013-02-06 with total page 641 pages. Available in PDF, EPUB and Kindle. Book excerpt: Following the much acclaimed success of the first volume of Key Topics in Conservation Biology, this entirely new second volume addresses an innovative array of key topics in contemporary conservation biology. Written by an internationally renowned team of authors, Key Topics in Conservation Biology 2 adds to the still topical foundations laid in the first volume (published in 2007) by exploring a further 25 cutting-edge issues in modern biodiversity conservation, including controversial subjects such as setting conservation priorities, balancing the focus on species and ecosystems, and financial mechanisms to value biodiversity and pay for its conservation. Other chapters, setting the framework for conservation, address the sociology and philosophy of peoples’ relation with Nature and its impact on health, and such challenging practical issues as wildlife trade and conflict between people and carnivores. As a new development, this second volume of Key Topics includes chapters on major ecosystems, such as forests, islands and both fresh and marine waters, along with case studies of the conservation of major taxa: plants, butterflies, birds and mammals. A further selection of topics consider how to safeguard the future through monitoring, reserve planning, corridors and connectivity, together with approaches to reintroduction and re-wilding, along with managing wildlife disease. A final chapter, by the editors, synthesises thinking on the relationship between biodiversity conservation and human development. Each topic is explored by a team of top international experts, assembled to bring their own cross-cutting knowledge to a penetrating synthesis of the issues from both theoretical and practical perspectives. The interdisciplinary nature of biodiversity conservation is reflected throughout the book. Each essay examines the fundamental principles of the topic, the methodologies involved and, crucially, the human dimension. In this way, Key Topics in Conservation Biology 2, like its sister volume, Key Topics in Conservation Biology, embraces issues from cutting-edge ecological science to policy, environmental economics, governance, ethics, and the practical issues of implementation. Key Topics in Conservation Biology 2 will, like its sister volume, be a valuable resource in universities and colleges, government departments, and conservation agencies. It is aimed particularly at senior undergraduate and graduate students in conservation biology and wildlife management and wider ecological and environmental subjects, and those taking Masters degrees in any field relevant to conservation and the environment. Conservation practitioners, policy-makers, and the wider general public eager to understand more about important environmental issues will also find this book invaluable.
Download or read book Wolves in the Land of Salmon written by David Moskowitz and published by Timber Press. This book was released on 2013-04-15 with total page 519 pages. Available in PDF, EPUB and Kindle. Book excerpt: Long considered an icon of the wild, wolves capture our imagination and spark controversy. Humans are the adult wolf’s only true natural predator; its return to the old-growth forests and wild coastlines of the Pacific Northwest renews age-old questions about the value of wildlands and wildlife. As the vivid stories unfold in this riveting and timely book, wolves emerge as smart, complex players uniquely adapted to the vast interdependent ecosystem of this stunning region. Observing them at close range, David Moskowitz explores how they live, hunt, and communicate, tracing their biology and ecology through firsthand encounters in the wildlands of the Northwest. In the process he challenges assumptions about their role and the impact of even well-meaning human interventions.

Download or read book Forest Land Conversion Ecosystem Services and Economic Issues for Policy written by Robert A. Smail and published by DIANE Publishing. This book was released on 2010-10 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: The continued conversion and development of forest land pose a serious threat to the ecosystem services derived from forested landscapes. There are unavoidable challenges involved in quantifying the threats from forest conversion and their related costs to human well-being: (1) most attempts to quantify the costs of forest conversion on ecosystem services will necessarily rely on specific ecological science that is often emerging, changing, or simply nonexistent; (2) given the interconnected nature of ecosystem products and processes, any attempt to quantify the effects of forest conversion must grapple with jointness in production; (3) the ecology and the human dimensions of ecosystems are highly specific to spatial-temporal circumstances.

Book excerpt: "In The Future of the Wild, conservationist Jonathan S. Adams uses stories to show us how to think big.
