Download or read book The Northern Yellowstone Elk Debate written by Craig L. Shafer and published by . This book was released on 2000 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Which management strategy, intervention or nonintervention, is best for the northern elk herd of Yellowstone National Park? This question was first raised in the early part of the twentieth century and resurfaced in the 1960s, prompting controversy that continues today. In response, Congress in 1997 requested that the National Academy of Sciences study the issue. This paper examines relevant National Park Service history and policy regarding this debate. Some of the primary factors scientists think have influenced elk abundance and distribution are profiled, and inherent semantic problems are examined. The 1969 natural regulation hypothesis, which has governed Yellowstone park policy since 1967, and its associated assumptions are defined. The interrelated technical issues that are key to the natural regulation hypothesis include migration and outside land conversion, historical elk population size, range expansion, baseline conditions, population stability, Native Americans, predation and fire, and sport hunting. In his paper he also revisits an obscure 1917 scientific hypothesis-that landscape alteration outside Yellowstone influences elk abundance inside the park-and restates it in broader, more modern terms: national park size influences the need for management intervention because of alteration of natural processes outside park boundaries. Some scientists perceive that intervention in the management of national park natural resources has decreased since 1872. Thus, this paper also asks whether the need for intervention is increasing as large spatial scale natural processes are progressively impeded outside the parks. Looking at the range of park natural units as a whole, a mixture of intervention and nonintervention may be the best approach.

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

Available in PDF, EPUB and Kindle. Book excerpt: "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.

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.

Download or read book Yellowstone Wolves written by Douglas W. Smith and published by University of Chicago Press. This book was released on 2020-12-28 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Elk Calf Survival and Mortality Yellowstone National Park written by Shannon Michelle Barber-Meyer and published by . This book was released on 2008 with total page 31 pages. Available in PDF, EPUB and Kindle. Book excerpt: We conducted a 3-year study (May 2003?Apr 2006) of mortality of northern Yellowstone elk (Cervus elaphus) calves to determine the cause for the recruitment decline (i.e., 33 calves to 13 calves/100 adult F) following the restoration of wolves (Canis lupus). We captured, fit with radiotransmitters, and evaluated blood characteristics and disease antibody seroprevalence in 151 calves6 days old (68M:83F). Concentrations (x, SE) of potential condition indicators were as follows: thyroxine (T4; 13.8 lg/dL, 0.43), serum urea nitrogen (SUN; 17.4 mg/dL, 0.57), c-glutamyltransferase (GGT; 66.4 IU/L, 4.36), gamma globulins (GG; 1.5 g/dL, 0.07), and insulin-like growth factor-1 (IGF-1; 253.6 ng/mL, 9.59). Seroprevalences were as follows: brucellosis (Brucella abortus; 3%), bovine-respiratory syncytial virus (3%), bovine-viral-diarrhea virus type 1 (25%), infectious-bovine rhinotracheitis (58%), and bovine parainfluenza-3 (32%). Serum urea nitrogen, GGT, GG, and IGF-1 varied with year; T4, SUN, andGGvaried with age (P 0.01); and SUN varied by capture area (P?0.02). Annual survival was 0.22 (SE?0.035, n?149) and varied by calving area but not year. Neonates captured in the Stephens Creek/Mammoth area of Yellowstone National Park, USA, had annual survival rates .33higher (0.54) than those captured in the Lamar Valley area (0.17), likely due to the higher predator density in Lamar Valley. Summer survival (20 weeks after radiotagging) was 0.29 (SE?0.05, n?116), and calving area, absolute deviation from median birth date, and GG were important predictors of summer survival. Survival during winter (Nov?Apr) was 0.90 (SE?0.05, n?42), and it did not vary by calving area or year. Sixty-nine percent (n?104) of calves died within the first year of life, 24% (n?36) survived their first year, and 7% (n?11) had unknown fates. Grizzly bears (Ursus arctos) and black bears (Ursus americanus) accounted for 58?60% (n ? 60?62) of deaths, and wolves accounted for 14?17% (n ? 15?18). Summer predation (95% of summer deaths) increased, and winter malnutrition (0% of winter deaths) decreased, compared with a similar study during 1987?1990 (72% and 58%, respectively). Physiological factors (e.g., low levels of GG) may predispose calves to predation. Also, the increase in bear numbers since wolf restoration and spatial components finer than the northern range should be considered when trying to determine the causes of the northern Yellowstone elk decline. This is the first study to document the predation impacts from reintroduced wolves on elk calf mortality in an ecosystem already containing established populations of 4 other major predators (i.e., grizzly and black bears, cougars [Puma concolor], and coyotes [Canis latrans]). The results are relevant to resource managers of the Yellowstone ecosystem in understanding the dynamics of the elk population, in providing harvest quota recommendations for local elk hunts to the Montana Department of Fish, Wildlife and Parks, the United States Fish and Wildlife Service regarding wolf and grizzly bear recovery, and to all areas worldwide where predators are increasing, by providing managers with information about potential carnivore impacts on elk populations. -- Abstract.
