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.

The new Equid Action Plan provides current knowledge on the biology, ecology and conservation status of wild zebras, asses, and horses. It specifies what information is lacking, and prioritizes needed conservation actions. The Action Plan also provides chapters on equid taxonomy, genetics, reproductive biology, and population dynamics. These chapters highlight unsolved issues of taxonomy and genetics. They also provide information and insight into the special demographic and genetic challenges of managing small populations. The chapter on disease provides a review of documented equine disease and epidemiology and focuses on priorities for equid conservation health. The final chapter deals with the importance of developing an assessment methodology that explicitly considers the role of equids in ecosystems and the ecological processes that are necessary for ecosystem viability. The approach of combining ecological field studies and ecosystem modeling should prove useful for the scientific management and conservation of wild equids worldwide. These chapters provide research and conservation practitioners with new information and paradigms.
