Book Description
"The beloved Yellowstone National Park underwent a management shift in 1969 that drastically altered its landscape. This book comes at a time when scientific results are sometimes withheld so that they do not challenge policy positions. The author charges that Yellowstone-supported research has produced a faulty ecological paradigm, whether consciously or not, in order to maintain status quo of the Park's "natural-regulation" policy." "Wagner's ecosystem model of the Park's northern range focuses on a low-elevation region of the Park where a large herd of Rocky Mountain elk winters. His study spans 132 years of ecological, hydrologic, archaeological, photographic, and historic evidence and synthesizes the herd's impact over time."--BOOK JACKET.

Book Description
Wagner, one of our most distinguished wildlife biologists, is a strong critic of ecological practices in the national parks. This book provides an assessment of the ecological history of Yellowstone's northern range, since before the park existed, showing the impact of US Park Service policies on the health of the areas they oversee. He demonstrates that elk had been historically rare throughout the region and that overgrazing by elk has seriously degraded the landscape and altered the structure of the area. This is a major contribution to reconstructing the ecology of this region over the course of the past 500 years. It is also a critique of US Park Service management policies and their stewardship of the nation's most cherished natural areas. Wagner's book will generate substantial attention and debate both in the scientific and policy/management communities.

Book Description
This book is an authoritative work on the ecology of some of America's most iconic large mammals in a natural environment - and of the interplay between climate, landscape, and animals in the interior of the world's first and most famous national park.Central Yellowstone includes the range of one of the largest migratory populations of bison in North America as well as a unique elk herd that remains in the park year round. These populations live in a varied landscape with seasonal and often extreme patterns of climate and food abundance. The reintroduction of wolves into the park a decade ago resulted in scientific and public controversy about the effect of large predators on their prey, a debate closely examined in the book. Introductory chapters describe the geography, geology and vegetation of the ecosystem. The elk and bison are then introduced and their population ecology described both pre- and post– wolf introduction, enabling valuable insights into the demographic and behavioral consequences for their ungulate prey. Subsequent chapters describe the wildlife-human interactions and show how scientific research can inform the debate and policy issues surrounding winter recreation in Yellowstone. The book closes with a discussion of how this ecological knowledge can be used to educate the public, both about Yellowstone itself and about science, ecology and the environment in general. Yellowstone National Park exemplifies some of the currently most hotly debated and high-profile ecological, wildlife management, and environmental policy issues and this book will have broad appeal not only to academic ecologists, but also to natural resource students, managers, biologists, policy makers, administrators and the general public. - Unrivalled descriptions of ecological processes in a world famous ecosystem, based on information from 16 years of painstaking field work and collaborations among 66 scientists and technical experts and 15 graduate studies - Detailed studies of two charismatic North American herbivore species – elk and bison - Description of the restoration of wolves into central Yellowstone and their ecological interactions with their elk and bison prey - Illustrated with numerous evocative colour photographs and stunning maps

Book Description
The world's first national park, Yellowstone is a symbol of nature's enduring majesty and the paradigm of protected areas across the globe. But Yellowstone is constantly changing. How we understand and respond to events that are putting species under stress, say the authors of Yellowstone's Wildlife in Transition, will determine the future of ecosystems that were millions of years in the making. With a foreword by the renowned naturalist E. O. Wilson, this is the most comprehensive survey of research on North America's flagship national park available today. Marshaling the expertise of over thirty contributors, Yellowstone's Wildlife in Transition examines the diverse changes to the park's ecology in recent decades. Since its creation in the 1870s, the priorities governing Yellowstone have evolved, from intensive management designed to protect and propagate depleted large-bodied mammals to an approach focused on restoration and preservation of ecological processes. Recognizing the importance of natural occurrences such as fires and predation, this more ecologically informed oversight has achieved notable successes, including the recovery of threatened native species of wolves, bald eagles, and grizzly bears. Nevertheless, these experts detect worrying signs of a system under strain. They identify three overriding stressors: invasive species, private-sector development of unprotected lands, and a warming climate. Their concluding recommendations will shape the twenty-first-century discussion over how to confront these challenges, not only in American parks but for conservation areas worldwide. Highly readable and fully illustrated, Yellowstone's Wildlife in Transition will be welcomed by ecologists and nature enthusiasts alike.

Book Description
Nature’s Burdens is a political and intellectual history of American natural resource conservation from the 1980s into the twenty-first century—a period of intense political turmoil, shifting priorities among federal policymakers, and changing ideas about the goals of conservation. Telling a story of persistent activism, conflict, and frustration but also of striking achievement, it is an account of how new ideas and policies regarding human relationships to plants, animals, and their surroundings have become vital features of modern environmentalism. In the 1960s and 1970s, Congress embraced the largely dormant movement to preserve distinctive landscapes and the growing demand for outdoor recreation, establishing an unprecedented number of parks, monuments, and recreation areas. The election of Ronald Reagan and a shift to a Republican-controlled Senate brought this activity to an abrupt halt and introduced a period of intense partisanship and legislative gridlock that extends to the present. In this political climate, three developments largely defined the role of conservation in contemporary society: environmental organizations have struggled to defend the legal status quo, private land conservation has become increasingly important, and the emergence of potent scientific voices has promoted the protection of animals and plants and injected a new sense of urgency into the larger cause. These developments mark this period as a distinctive and important chapter in the history of American conservation. Scrupulously researched, scientifically and politically well informed, concise, and accessibly written, Nature’s Burdens is the most comprehensive examination of recent efforts to protect and enhance the natural world. It will be of interest to environmental historians, environmental activists, and any general reader interested in conservation.

Book Description
During the nineteenth century, ivory hunting caused a substantial decrease of elephant numbers in southern Africa. Soon after that, populations of many other large and medium-sized herbivores went into steep decline due to the rinderpest pandemic in the 1890s. These two events provided an opportunity for woodland establishment in areas previously intensively utilized by elephants and other herbivores. The return of elephants to currently protected areas of their former range has greatly influenced vegetation locally and the resulting potential negative effects on biodiversity are causing concern among stakeholders, managers, and scientists. This book focuses on the ecological effects of the increasing elephant population in northern Botswana, presenting the importance of the elephants for the heterogeneity of the system, and showing that elephant ecology involves much wider spatiotemporal scales than was previously thought. Drawing on the results of their research, the authors discuss elephant-caused effects on vegetation in nutrient-rich and nutrient-poor savannas, and the potential competition between elephants on the one hand and browsers and mixed feeders on the other. Ultimately this text provides a comprehensive review of ecological processes in African savannas, covering long-term ecosystem changes and human-wildlife conflicts. It summarises new knowledge on the ecology of the sub-humid African savanna ecosystems to advance the general functional understanding of savanna ecosystems across moisture and nutrient gradients.

Book Description
This beautifully illustrated volume on the Yellowstone Wolf Project includes an introduction by Jane Goodall and an exclusive online documentary. The reintroduction of wolves to Yellowstone National Park was one of the greatest wildlife conservation achievements of the twentieth century. Eradicated after the park was first established, these iconic carnivores returned in 1995 when the US government reversed its century-old policy of extermination. In the intervening decades, scientists have built a one-of-a-kind field study of these wolves, their behaviors, and their influence on the entire ecosystem. Yellowstone Wolves tells the incredible story of the Yellowstone Wolf Project, as told by the people behind it. This wide-ranging volume highlights what has been learned in the decades since reintroduction, as well as the unique blend of research techniques used to gain this knowledge. We learn about individual wolves, population dynamics, wolf-prey relationships, genetics, disease, management and policy, and the rippling ecosystem effects wolves have had on Yellowstone’s wild and rare landscape. Featuring a foreword by Jane Goodall, beautiful images, a companion online documentary by celebrated filmmaker Bob Landis, and contributions from more than seventy wolf and wildlife conservation luminaries from Yellowstone and around the world, Yellowstone Wolves is an informative and beautifully realized celebration of the extraordinary Yellowstone Wolf Project.
