This book was released on 2002-02-01 with total page 199 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecological Dynamics on Yellowstone's Northern Range discusses the complex management challenges in Yellowstone National Park. Controversy over the National Park Service's approach of "natural regulation" has heightened in recent years because of changes in vegetation and other ecosystem components in Yellowstone's northern range. Natural regulation minimizes human impacts, including management intervention by the National Park Service, on the park ecosystem. Many have attributed these changes to increased size of elk and other ungulate herds. This report examines the evidence that increased ungulate populations are responsible for the changes in vegetation and that the changes represent a major and serious change in the Yellowstone ecosystem. According to the authors, any human intervention to protect species such as the aspen and those that depend on them should be prudently localized rather than ecosystem-wide. An ecosystem-wide approach, such as reducing ungulate populations, could be more disruptive. The report concludes that although dramatic ecological change does not appear to be imminent, approaches to dealing with potential human-caused changes in the ecosystem, including those related to climate change, should be considered now. The need for research and public education is also compelling.
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 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 Wildlife by : Paul A. Johnsgard
Download or read book Yellowstone Wildlife written by Paul A. Johnsgard and published by University Press of Colorado. This book was released on 2013-06-15 with total page 245 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Book Synopsis Coexisting with Large Carnivores by : Tim Clark
Download or read book Coexisting with Large Carnivores written by Tim Clark and published by Island Press. This book was released on 2013-04-10 with total page 307 pages. Available in PDF, EPUB and Kindle. Book excerpt: As in the rest of the United States, grizzly bears, wolves, and mountain lions in and around Yellowstone National Park were eliminated or reduced decades ago to very low numbers. In recent years, however, populations have begun to recover, leading to encounters between animals and people and, more significantly, to conflicts among people about what to do with these often controversial neighbors. Coexisting with Large Carnivores presents a close-up look at the socio-political context of large carnivores and their management in western Wyoming south of Yellowstone National Park, including the southern part of what is commonly recognized as the Greater Yellowstone Ecosystem. The book brings together researchers and others who have studied and worked in the region to help untangle some of the highly charged issues associated with large carnivores, their interactions with humans, and the politics that arise from those interactions. This volume argues that coexistence will be achieved only by a thorough understanding of the human populations involved, their values, attitudes, beliefs, and the institutions through which carnivores and humans are managed. Coexisting with Large Carnivores offers important insights into this complex, dynamic issue and provides a unique overview of issues and strategies for managers, researchers, government officials, ranchers, and everyone else concerned about the management and conservation of large carnivores and the people who live nearby.

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 Yellowstone Wolf by : Paul Schullery
Download or read book The Yellowstone Wolf written by Paul Schullery and published by University of Oklahoma Press. This book was released on 2003 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: All royalties from sales of this book go to Yellowstone’s wolf recovery project Few animals inspire such a mixture of fear, curiosity, and wonder as the wolf. Highly regarded but often misunderstood, the wolf has as many friends as enemies, and its reintroduction into Yellowstone National Park has sparked both fascination and controversy. Early in Yellowstone’s history, wolves were thought supernaturally evil, and scores were destroyed. Northern Rocky Mountain wolves were native to Yellowstone when the park was established in 1872, but “predator control” led to determined eradication, and by the 1940s they were gone. Amid much fanfare, however, wolves were reintroduced to one of the nation’s oldest national parks in the 1990s. This comprehensive reference documents the prehistory, management, and nature of the Yellowstone wolf. Historian-naturalist Paul Schullery has assembled the voices of explorers, naturalists, park officials, tourists, lawmakers, and modern researchers to tell the story of what may be the most famous wolf population in the world. This unique book includes numerous scientific studies of interest to wolf enthusiasts and scholars of western wildlife issues, conservation, and national parks. In a new afterword, Schullery discusses recent developments in the recovery project.
