Download or read book Endangered Rivers and the Conservation Movement written by Tim Palmer and published by Rowman & Littlefield Publishers. This book was released on 2004-02-09 with total page 381 pages. Available in PDF, EPUB and Kindle. Book excerpt: A dam proposal sparked the first great conservation battle in the United States when John Muir fought to safeguard Hetch Hetchy Valley in Yosemite National Park. Since then, people have worked to preserve free-flowing rivers from Florida to Alaska, and in doing so, they have changed the way natural resources are managed in America. In Endangered Rivers, Tim Palmer traces the growth of this movement and he chronicles the development of a national consciousness that values our rivers as lifelines for wildlife, fisheries, parks, wilderness, recreation, and communities. Based on careful research and hundreds of interviews, Palmer's information-packed narrative is regarded as a classic in the field of conservation. The first edition of this book is now updated and includes two new chapters that chart the course of conservation during the past twenty years and explore how the movement to protect rivers will likely change in the twenty-first century. This book will fascinate all who care about rivers and it will engage those who seek to understand environmental history, resources management, and the evolution of government programs in response to people's changing needs.
Download or read book Endangered and Threatened Species of the Platte River written by National Research Council and published by National Academies Press. This book was released on 2005-02-24 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: The tension between wildlife protection under the Endangered Species Act and water management in the Platte River Basin has existed for more than 25 years. The Platte River provides important habitat for migratory and breeding birds, including three endangered or threatened species: the whooping crane, the northern Great Plains population of the piping plover, and the interior least tern. The leading factors attributed to the decline of the cranes are historical overhunting and widespread habitat destruction and, for the plovers and terns, human interference during nesting and the loss of riverine nesting sites in open sandy areas that have been replaced with woodlands, sand and gravel mines, housing, and roadways. Extensive damming has disrupted passage of the endangered pallid sturgeon and resulted in less suitable habitat conditions such as cooler stream flows, less turbid waters, and inconsistent flow regimes. Commercial harvesting, now illegal, also contributed to the decline of the sturgeon. Endangered and Threatened Species of the Platte River addresses the habitat requirements for these federally protected species. The book further examines the scientific aspects of the U.S. Fish and Wildlife Service's instream-flow recommendations and habitat suitability guidelines and assesses the science concerning the connections among the physical systems of the river as they relate to species' habitats.
Download or read book Protecting Yellowstone written by Michael J. Yochim and published by UNM Press. This book was released on 2013 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: Yellowstone National Park looks like a pristine western landscape populated by its wild inhabitants: bison, grizzly bears, and wolves. But the bison do not always range freely, snowmobile noise intrudes upon the park's profound winter silence, and some tourist villages are located in prime grizzly bear habitat. Despite these problems, the National Park Service has succeeded in reintroducing wolves, allowing wildfires to play their natural role in park forests, and prohibiting a gold mine that would be present in other more typical western landscapes. Each of these issues--bison, snowmobiles, grizzly bears, wolves, fires, and the New World Mine--was the center of a recent policy-making controversy involving federal politicians, robust debate with interested stakeholders, and discussions about the relevant science. Yet, the outcomes of the controversies varied considerably, depending on politics, science, how well park managers allied themselves with external interests, and public thinking about the effects of park proposals on their access and economies. Michael Yochim examines the primary influences upon contemporary national park policy making and considers how those influences shaped or constrained the final policy. In addition, Yochim considers how park managers may best work within the contemporary policy-making context to preserve national parks.

Available in PDF, EPUB and Kindle. Book excerpt: "In Wide Rivers Crossed, Ellen Wohl tells the stories of two rivers—the South Platte on the western plains and the Illinois on the eastern—to represent the environmental history and historical transformation of major rivers across the American prairie. Wohl begins with the rivers’ natural histories, including their geologic history, physical characteristics, ecological communities, and earliest human impacts, and follows a downstream and historical progression from the use of the rivers’ resources by European immigrants through increasing population density of the twentieth century to the present day. The environmental changes in the South Platte and the Illinois reflect the relentless efforts by humans to control the distribution of water: to enhance surface water in the arid western prairie and to limit the spread of floods and drain the wetlands along the rivers in the water-abundant east. In addition, during the past two centuries crops replaced native vegetation; excess snowmelt and rainfall carried fertilizers and pesticides into streams; and levees, dams, and drainage altered distribution. These changes cascaded through networks, starting in small headwater tributaries, and reduced the ability of rivers to supply the clean water, fertile soil, and natural habitats they had provided for centuries. Understanding how these rivers, and rivers in general, function and how these functions have been altered over time will allow us to find innovative approaches to restoring river ecosystems. Wide Rivers Crossed looks at these historical changes and discusses opportunities for much needed protection and restoration for the future."
