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.

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.

This well-received book, now in its second edition, is designed for an introductory course in statistics for students of statistics, mathematics and management. In addition, postgraduate students of a variety of disciplines such as psychology, sociology, anthropology, biology, nursing and criminal justice, as well as professionals, surveyors and administrators will also find this book extremely helpful. The book provides students with a strong foundation in the principles of statistics. It develops a thorough understanding of the fundamental concepts through extensive use of illustrative and motivating examples and shows how these concepts can be applied to real-life situations. The text explains each statistical technique and formula in a step-by-step manner with the help of small datasets. While discussing a wide range of topics, mathematical complexity has been kept at a bare minimum, and intuitive ideas have been given for each mathematical expression. Key concepts have been highlighted in boxes throughout the text. Chapter-end summaries in the form of flowchart capture all the important points. Chapter-end exercises with answers and the Question Bank containing about 150 questions offer the students the opportunity to test their ability to comprehend the concepts. Besides, this text illustrates the use of SPSS and Excel in carrying out statistical analysis.  Provides a new section on ‘Testing Normality’ of a given a dataset.  Expands Use of Technology sections with coverage of the use of Excel to perform statistical analysis.  Offers a new appendix containing Multiple-Choice Questions as brain-teasers.  Includes Excel example datasets, SPSS datasets, and the solutions to Question Bank on the companion CD. Solutions Manual containing the complete worked-out solutions to chapter-end exercises and Question Bank is available for instructors.

The first expert synthesis of the diverse studies conducted on wild equids worldwide. Wild horses, zebras, asses, and feral equines exhibit intriguing and complex social structures that captivate the human imagination and elicit a wide range of emotions that influence conservation and management efforts. This book, spearheaded by Jason I. Ransom and Petra Kaczensky, brings together the world's leading experts on equid ecology, management, and conservation to provide a synthesis of what is known about these iconic species and what needs to be done to prevent losing some of them altogether. The most comprehensive conservation book on wild equids in decades, this title will enlighten not only equid researchers, but also mammalogists, conservationists, and equine professionals. Readers will find new insight into the lives of the world's horses, zebras, and asses, understand the basis of our relationships with these animals, and develop a greater understanding of where equids come from and why they are worth conserving. Included in this book are detailed, state-of-the-science syntheses on Social structure, behavior, and cognition Habitat and diet Ecological niches Population dynamics Roles of humans in horse distribution through time Human dimensions and the meaning of wild Management of free-roaming horses Captive breeding of wild equids Conservation of wild equids Conservation of migrations Reintroductions Genetics and paleogenetics
