Rangelands: A Resource Under Siege by P. J. Joss,P. W. Lynch,O. B. Williams Pdf
This volume comprises the proceedings of the Second International Rangelands Congress held in Adelaide, Australia in May 1984, and includes some 350 contributions drawn from 43 different countries. The Congress addressed the problem of the conflict between land-users and the degradation of this valuable resource. Some 40% of the Earth's land surface is and or alpine and therefore unsuitable for agricultural cultivation. Collectively, these lands are known as rangelands and in their natural state they constitute a habitat for grazing animals, both domestic and wild. Despite their low productivity, rangelands have been used for thousands of years as a source of food and fibre, but other uses such as mining, tourism, recreation and conservation are exerting increasing demands. The result is often conflict between land-users and degradation of the resource.
This book is open access under a CC BY-NC 2.5 license. This book provides an unprecedented synthesis of the current status of scientific and management knowledge regarding global rangelands and the major challenges that confront them. It has been organized around three major themes. The first summarizes the conceptual advances that have occurred in the rangeland profession. The second addresses the implications of these conceptual advances to management and policy. The third assesses several major challenges confronting global rangelands in the 21st century. This book will compliment applied range management textbooks by describing the conceptual foundation on which the rangeland profession is based. It has been written to be accessible to a broad audience, including ecosystem managers, educators, students and policy makers. The content is founded on the collective experience, knowledge and commitment of 80 authors who have worked in rangelands throughout the world. Their collective contributions indicate that a more comprehensive framework is necessary to address the complex challenges confronting global rangelands. Rangelands represent adaptive social-ecological systems, in which societal values, organizations and capacities are of equal importance to, and interact with, those of ecological processes. A more comprehensive framework for rangeland systems may enable management agencies, and educational, research and policy making organizations to more effectively assess complex problems and develop appropriate solutions.

Using Science to Improve the BLM Wild Horse and Burro Program by National Research Council,Division on Earth and Life Studies,Board on Agriculture and Natural Resources,Committee to Review the Bureau of Land Management Wild Horse and Burro Management Program Pdf
Using Science to Improve the BLM Wild Horse and Burro Program: A Way Forward reviews the science that underpins the Bureau of Land Management's oversight of free-ranging horses and burros on federal public lands in the western United States, concluding that constructive changes could be implemented. The Wild Horse and Burro Program has not used scientifically rigorous methods to estimate the population sizes of horses and burros, to model the effects of management actions on the animals, or to assess the availability and use of forage on rangelands. Evidence suggests that horse populations are growing by 15 to 20 percent each year, a level that is unsustainable for maintaining healthy horse populations as well as healthy ecosystems. Promising fertility-control methods are available to help limit this population growth, however. In addition, science-based methods exist for improving population estimates, predicting the effects of management practices in order to maintain genetically diverse, healthy populations, and estimating the productivity of rangelands. Greater transparency in how science-based methods are used to inform management decisions may help increase public confidence in the Wild Horse and Burro Program.
Rangeland Health by National Research Council,Board on Agriculture,Committee on Rangeland Classification Pdf
Rangelands comprise between 40 and 50 percent of all U.S. land and serve the nation both as productive areas for wildlife, recreational use, and livestock grazing and as watersheds. The health and management of rangelands have been matters for scientific inquiry and public debate since the 1880s, when reports of widespread range degradation and livestock losses led to the first attempts to inventory and classify rangelands. Scientists are now questioning the utility of current methods of rangeland classification and inventory, as well as the data available to determine whether rangelands are being degraded. These experts, who are using the same methods and data, have come to different conclusions. This book examines the scientific basis of methods used by federal agencies to inventory, classify, and monitor rangelands; it assesses the success of these methods; and it recommends improvements. The book's findings and recommendations are of interest to the public; scientists; ranchers; and local, state, and federal policymakers.

Wild Rangelands by Johan T. du Toit,Richard Kock,James Deutsch Pdf
Rangeland ecosystems which include unimproved grasslands, shrublands, savannas and semi-deserts, support half of the world’s livestock, while also providing habitats for some of the most charismatic of wildlife species. This book examines the pressures on rangeland ecosystems worldwide from human land use, over-hunting, and subsistence and commercial farming of livestock and crops. Leading experts have pooled their experiences from all continents to cover the ecological, sociological, political, veterinary, and economic aspects of rangeland management today. This book provides practitioners and students of rangeland management and wildland conservation with a diversity of perspectives on a central question: can rangelands be wildlands? The first book to examine rangelands from a conservation perspective Emphasizes the balance between the needs of people and livestock, and wildlife Written by an international team of experts covering all geographical regions Examines ecological, sociological, political, veterinary, and economic aspects of rangeland management and wildland conservation, providing a diversity of perspectives not seen before in a single volume

Concepts of Ecosystem Ecology by Lawrence R. Pomeroy,James J. Alberts Pdf
In this volume 19 leading experts offer a timely and coherent overview of the fundamental principles of ecosystem science. They examine the flux of energy and biologically essential elements and their associated food webs in major terrestrial and aquatic ecosystems, such as forests, grasslands, cultivated land, streams, coral reefs, and ocean basins. In each case, interactions between different eosystems, predictive models, and the application of ecosystem research to the management of natural resources are given special emphasis. A number of theoretical chapters provide a synthesis through critical discussion of current concepts of ecosystem energetics and dynamics.
