Book Synopsis Greater Yellowstone's Native Ungulates by : Joel Berger

Book excerpt: At least three North American areas have been compared to Africa's Serengeti, probably because large concentrations of ungulates occur on both continents. Such comparisons are deceiving because the North American eco- systems harbor only about 15 to 25% of the ungulate species diversity found in the Serengeti. Migratory herbivores in both systems are confronted by ecological problems, including conflicts between people and wildlife once the herbivores move beyond park boundaries, and in the North American system, the loss of effective predators. The recent extinction of wolves from the Greater Yellowstone Ecosystem masks any direct effect on large herbivore movements today, al- though more than half of the Yellowstone Park ungulates migrate regularly to habitats outside park boundaries. If vestiges of ecosystem-oriented processes are to be preserved, some type of vision coupled with effective, coordinated management must be adopted. This paper addresses one component of this issue, migrant ungulates and their habitats. Three specific points are made. (1) Comparisons between the Greater Yellowstone Ecosystem and Serengeti, while questionable ecologically, are heuristic and serve conservation goals. (2) Both the loss of predators and different federally imposed land-use mandates have altered patterns of herbivore migration, behavior, and habitat use. While consequences of these human-caused disturbances cannot be predicted precisely, sufficient data from comparable regions allow the development of probable scenarios. (3) Throughout different periods during the last 100 years a variety of plans called for formal interagency cooperation; none has been successful. Until managers and politicians become more cognizant of historical failures stemming from the lack of coordinated ecosystem management during the last century, the same mistakes are likely to plague future generations.
Book Synopsis Browsing by Native Ungulates by : Charles Kay
Download or read book Browsing by Native Ungulates written by Charles Kay and published by . This book was released on 1995 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Long-term grazing exclosures were used to compare browsed versus unbrowsed shrubs in the Greater Yellowstone Ecosystem. Deciduous shrubs protected from wild ungulates exhibited significantly greater canopy-cover, height, size, and volume than unprotected plants. Browsed shrub populations were dominated by significantly smaller plants than were unbrowsed populations. Protected shrubs increased in canopy-coverage and size while browsed plants remained static or declined. Ungulate browsing in recent times has virtually eliminated shrub seed production in areas frequented by wintering elk. Shrubs measured inside exclosures produced up to 20,000 times more berries than unprotected plants. Individual unprotected shrubs with a few stems beyond the reach of ungulates displayed a similar pattern. Stems above the browse height (2.5 m) produced an abundance of berries while none were produced on that portion of the plants exposed to browsing. Old photographs and historical journals indicate that tall shrubs and berries were common prior to park establishment, so the present lack of berries and the browsingstunted shrub growth form were not the conditions prevailing in pre-European times. The virtual elimination of shrub seed production over much of the ecosystem suggests that ungulate populations are not in equilibrium with their food resources, as required under the ?natural regulation? paradigm. These circumstances are not unique to Yellowstone. Similar situations exist in other Western States where wild ungulate numbers are at historical highs. At many locations, large populations of native ungulates are having dramatic impacts on shrub growth and seed production. Without adequate seed production and recruitment, existing plants are not replaced when they die, and plant populations cannot be in long-term equilibrium with herbivores or the environment. By reducing or eliminating seed production, native ungulates may render long-term shrub restoration ineffective. The impact of native ungulates should be carefully considered in the planning and implementation of all shrub revegetation projects.
Book Synopsis The Ecology of Large Mammals in Central Yellowstone by : Robert A. Garrott
Download or read book The Ecology of Large Mammals in Central Yellowstone written by Robert A. Garrott and published by Academic Press. This book was released on 2008-11-25 with total page 712 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 Synopsis Yellowstone's Destabilized Ecosystem by : Frederic H. Wagner
Download or read book Yellowstone's Destabilized Ecosystem written by Frederic H. Wagner and published by Oxford University Press. This book was released on 2006-05-25 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 Synopsis Fire, Native Peoples, and the Natural Landscape by : Thomas Vale
Download or read book Fire, Native Peoples, and the Natural Landscape written by Thomas Vale and published by Island Press. This book was released on 2013-04-16 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: For nearly two centuries, the creation myth for the United States imagined European settlers arriving on the shores of a vast, uncharted wilderness. Over the last two decades, however, a contrary vision has emerged, one which sees the country's roots not in a state of "pristine" nature but rather in a "human-modified landscape" over which native peoples exerted vast control. Fire, Native Peoples, and the Natural Landscape seeks a middle ground between those conflicting paradigms, offering a critical, research-based assessment of the role of Native Americans in modifying the landscapes of pre-European America. Contributors focus on the western United States and look at the question of fire regimes, the single human impact which could have altered the environment at a broad, landscape scale, and which could have been important in almost any part of the West. Each of the seven chapters is written by a different author about a different subregion of the West, evaluating the question of whether the fire regimes extant at the time of European contact were the product of natural factors or whether ignitions by Native Americans fundamentally changed those regimes. An introductory essay offers context for the regional chapters, and a concluding section compares results from the various regions and highlights patterns both common to the West as a whole and distinctive for various parts of the western states. The final section also relates the findings to policy questions concerning the management of natural areas, particularly on federal lands, and of the "naturalness" of the pre-European western landscape.

Download or read book Yellowstone’s Wildlife in Transition written by P. J. White and published by Harvard University Press. This book was released on 2013-04-15 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
