The world's first national park is constantly changing. How we understand and respond to recent events putting species under stress will determine the future of ecosystems millions of years in the making. Marshaling expertise from over 30 contributors, Yellowstone's Wildlife in Transition examines three primary challenges to the park's ecology.

American ecologists seeking to influence the founders of the National Park Service had hoped that protection of the parks would create preserves where ?natural conditions? could exist in an idealized presettlement state. These hopes, however, produced a bitter irony. In order to secure a naturally functioning park, officials had to provide intensive management to preserve ?nature at work.? For the better part of the twentieth century, the forms this management has taken have polarized public opinion. ø James A. Pritchard?s Preserving Yellowstone?s Natural Conditions demonstrates that even the most up-to-date scientific policy could not reckon with public expectations and animal behavior. When Yellowstone stopped its bear feeding program in an attempt to restore naturally regulated bear populations, the public bemoaned the loss of the spectacle. The bears, meanwhile, had learned to associate humans with food, and the loss of reliable meals brought them into campsites. Park officials had to shoot bears that made a menace of themselves, leaving many people frustrated with the park?s attempts to preserve Yellowstone as a natural ecosystem. ø Pritchard believes that restoring natural conditions for bears and other animals is a sound idea. Yellowstone, he argues, represents an ecological anchor, a relatively untrammeled slice of nature. Despite decades of tampering, the park provides scientists and managers with an outdoor laboratory for examining natural processes that existed before extensive settlement.

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.

"This report provides evaluates [sic] the effectiveness of ecological process management at sustaining essential processes in Yellowstone National Park some 25 years after the initial assessment by Despain et al. (1986)... we provide select assessments that focus on keywildlife species and their habitats in the northern portion of the park and illustrate essential processes and current management issues. Then, in the final chapter, we discuss the future of ecological process management.? ? From Introduction.

Yellowstone Wildlife is a natural history of the wildlife species that call Yellowstone National Park and the Greater Yellowstone Ecosystem their home. Illustrated with stunning images by renowned wildlife photographer Thomas Mangelsen, Yellowstone Wildlife describes the lives of species in the park, exploring their habitats from the Grand Tetons to Jackson Hole. From charismatic megafauna like elk, bison, wolves, bighorn sheep, and grizzly bears, to smaller mammals like bats, pikas, beavers, and otters, to some of the 279 species of birds, Johnsgard describes the behavior of animals throughout the seasons, with sections on what summer and autumn mean to the wildlife of the park, especially with the intrusion of millions of tourists each year. Enhanced by Mangelsen’s wildlife photography, Yellowstone Wildlife reveals the beauty and complexity of these species’ intertwined lives and that of Yellowstone’s greater ecosystem.
