Book Synopsis Pioneering Conservation in Alaska by : Ken Ross
Download or read book Pioneering Conservation in Alaska written by Ken Ross and published by University Press of Colorado. This book was released on 2017-10-01 with total page 569 pages. Available in PDF, EPUB and Kindle. Book excerpt: A companion volume to Environmental Conflict in Alaska, Pioneering Conservation in Alaska chronicles the central land and wildlife issues and the growth of environmental conservation in Alaska during its Russian and territorial eras. The Alaskan frontier tempted fur traders, whalers, salmon fishers, gold miners, hunters, and oilmen to take what they could without regard for long-term consequences. Wildlife species, ecosystems, and Native cultures suffered, sometimes irreparably. Damage to wildlife and lands drew the attention of environmentalists, including John Muir, who applied their influence to enact wildlife protection laws and set aside lands for conservation. Alaska served as a testing ground for emergent national resource policy in the United States, as environmental values of species and ecosystem sustainability replaced the unrestrained exploitation of Alaska's early frontier days. Efforts of conservation leaders and the territory's isolation, small human population, and late development prevented widespread destruction and gave Americans a unique opportunity to protect some of the world's most pristine wilderness. Enhanced by more than 100 photographs, Pioneering Conservation in Alaska illustrates the historical precedents for current natural resource disputes in Alaska and will fascinate readers interested in wildlife and conservation.

Book Synopsis Problems in Management of Locally Abundant Wild Mammals by : P.A. Jewell
Download or read book Problems in Management of Locally Abundant Wild Mammals written by P.A. Jewell and published by Elsevier. This book was released on 2012-12-02 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: Problems in Management of Locally Abundant Wild Mammals contains the proceedings of the Management of Locally Abundant Wild Mammals: A Workshop to Examine the Need for and Alternatives to the Culling of Wild Animals, held in Yarmouth Port, Massachusetts from September 29 to October 3, 1980. Contributors reexamine the scientific basis for possible management aimed at restraining local increase in numbers of locally abundant wild mammals, with emphasis on the issue of culling. This text is organized into six sections encompassing 19 chapters and begins with an overview of the dilemma of local overabundance or overpopulation of threatened mammals. In particular, it considers the extent to which past predictions have been fulfilled in practice, and whether understanding of the dynamics of living systems is adequate for useful prediction. This book also discusses the circumstances that allow a species to become so abundant and the adverse effects that arise. The chapters that follow present case studies that reflect experiences around the world concerning management of locally abundant mammals, including the white rhino in South Africa and deer in North America. This book also explores proposed solutions for problems involving the management of polar bear, the Northwest Atlantic humpback whale, and the British grey seal. This reference material is a valuable resource for zoologists, conservation biologists, and those with interest in the protection of wild mammals.
