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.

"The public lands of the western United States comprise some 450 million acres of grassland, steppe land, canyons, forests, and mountains. It's an American commons, and it is under assault as never before. Journalist Christopher Ketcham has been documenting the confluence of commercial exploitation and governmental misconduct in this region for over a decade. His revelatory book takes the reader on a journey across these last wild places, to see how capitalism is killing our great commons. Ketcham begins in Utah, revealing the environmental destruction caused by unregulated public lands livestock grazing, and exposing rampant malfeasance in the federal land management agencies, who have been compromised by the profit-driven livestock and energy interests they are supposed to regulate. He then turns to the broad effects of those corrupt politics on wildlife. He tracks the Department of Interior's failure to implement and enforce the Endangered Species Act--including its stark betrayal of protections for the grizzly bear and the sage grouse--and investigates the destructive behavior of U.S. Wildlife Services in their shocking mass slaughter of animals that threaten the livestock industry. Along the way, Ketcham talks with ecologists, biologists, botanists, former government employees, whistleblowers, grassroots environmentalists and other citizens who are fighting to protect the public domain for future generations. This Land is a colorful muckraking journey--part Edward Abbey, part Upton Sinclair--exposing the rot in American politics that is rapidly leading to the sell-out of our national heritage"--

It is the largest landholder in America, overseeing nearly an eighth of the country: 258 million acres located almost exclusively west of the Mississippi River, with even twice as much below the surface. Its domain embraces wildlife and wilderness, timber, range, and minerals, and for over 60 years, the Bureau of Land Management has been an agency in search of a mission. This is the first comprehensive, analytical history of the BLM and its struggle to find direction. James Skillen traces the bureau's course over three periods—its formation in 1946 and early focus on livestock and mines, its 1970s role as mediator between commerce and conservation, and its experience of political gridlock since 1981 when it faced a powerful antienvironmental backlash. Focusing on events that have shaped the BLM's overall mission, organization, and culture, he takes up issues ranging from the National Environmental Policy Act to the Sagebrush Rebellion in order to paint a broad picture of the agency's changing role in the American West. Focusing on the vast array of lands and resources that the BLM manages, he explores the complex and at times contradictory ways that Americans have valued nature. Skillen shows that, although there have been fleeting moments of consensus over the purpose of national forests and parks, there has never been any such consensus over the federal purpose of the public lands overseen by the BLM. Highlighting the perennial ambiguities shadowing the BLM's domain and mission, Skillen exposes the confusion sown by conflicting congressional statutes, conflicting political agendas, and the perennial absence of public support. He also shows that, while there is room for improvement in federal land management, the criteria by which that improvement is measured change significantly over time. In the face of such ambiguity—political, social, and economic--Skillen argues that the agency's history of limited political power and uncertain mission has, ironically, better prepared it to cope with the more chaotic climate of federal land management in the twenty-first century. Indeed, operating in an increasingly crowded physical and political landscape, it seems clear that the BLM's mission will continue to be marked by ambiguity. For historians, students, public administrators, or anyone who cares about American lands, Skillen offers a cautionary tale for those still searching for a final solution to federal land and resource conflicts.

Loosely autobiographical, thirty vignettes make up this collection that features a wide range of equine stories, each sharing a sense of love, loss, and survival.

As a follow-up to the 2013 report Using Science to Improve the Wild Horse and Burro Program: A Way Forward, this letter report reviews research project proposals submitted to the Bureau of Land Management and aimed at developing new or refining existing techniques and establishing protocols for the contraception or permanent sterilization of either male or female wild horses and/or burros in the field. Review of Proposals to the Bureau of Land Management on Wild Horse and Burro Sterilization or Contraception considers factors related to the scientific validity of the proposed technique(s), goals and objectives of the work, research methodology and design of the study, proposed statistical analysis and interpretation of anticipated data obtained, animal welfare implications and Institutional Animal Care and Use Committee approvals, feasibility, as well as the qualifications, expertise, and experience of the investigators. This report ranks the proposals in order of merit and provides a brief report on additional factors for the Bureau of Land Management to consider in selecting proposals to fund.

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
