Wagner, one of our most distinguished wildlife biologists, is a strong critic of ecological practices in the national parks. This book provides an assessment of the ecological history of Yellowstone's northern range, since before the park existed, showing the impact of US Park Service policies on the health of the areas they oversee. He demonstrates that elk had been historically rare throughout the region and that overgrazing by elk has seriously degraded the landscape and altered the structure of the area. This is a major contribution to reconstructing the ecology of this region over the course of the past 500 years. It is also a critique of US Park Service management policies and their stewardship of the nation's most cherished natural areas. Wagner's book will generate substantial attention and debate both in the scientific and policy/management communities.

Yellowstone's northern range has inspired one of this century's most productive, if sometimes bitter, dialogues on the management of a wildland ecosystem. Document presents new scientific research about the range and synthesizes information that has previously been available only in specialized and technical journals. Interprets and summarizes the work of dozens of ecologists and other researchers from across the scientific community and provides Yellowstone National Park's formal administrative position on the northern range grazing issue.

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.

Livestock grazing is the most widespread commercial use of federal public lands. The image of a herd grazing on Bureau of Land Management or U.S. Forest Service lands is so traditional that many view this use as central to the history and culture of the West. Yet the grazing program costs far more to administer than it generates in revenues, and grazing affects all other uses of public lands, causing potentially irreversible damage to native wildlife and vegetation. The Western Range Revisited proposes a landscape-level strategy for conserving native biological diversity on federal rangelands, a strategy based chiefly on removing livestock from large tracts of arid BLM lands in ten western states: Arizona, California, Colorado, Idaho, Nevada, New Mexico, Oregon, Utah, Washington, Wyoming. Drawing from range ecology, conservation biology, law, and economics, Debra L. Donahue examines the history of federal grazing policy and the current debate on federal multiple-use, sustained-yield policies and changing priorities for our public lands. Donahue, a lawyer and wildlife biologist, uses existing laws and regulations, historical documents, economic statistics, and current scientific thinking to make a strong case for a land-management strategy that has been, until now, "unthinkable." A groundbreaking interdisciplinary work, The Western Range Revisited demonstrates that conserving biodiversity by eliminating or reducing livestock grazing makes economic sense, is ecologically expedient, and can be achieved under current law.

Brucellosis is a nationally and internationally regulated disease of livestock with significant consequences for animal health, public health, and international trade. In cattle, the primary cause of brucellosis is Brucella abortus, a zoonotic bacterial pathogen that also affects wildlife, including bison and elk. As a result of the Brucellosis Eradication Program that began in 1934, most of the country is now free of bovine brucellosis. The Greater Yellowstone Area (GYA), where brucellosis is endemic in bison and elk, is the last known B. abortus reservoir in the United States. The GYA is home to more than 5,500 bison that are the genetic descendants of the original free-ranging bison herds that survived in the early 1900s, and home to more than 125,000 elk whose habitats are managed through interagency efforts, including the National Elk Refuge and 22 supplemental winter feedgrounds maintained in Wyoming. In 1998 the National Research Council (NRC) issued a report, Brucellosis in the Greater Yellowstone Area, that reviewed the scientific knowledge regarding B. abortus transmission among wildlifeâ€"particularly bison and elkâ€"and cattle in the GYA. Since the release of the 1998 report, brucellosis has re-emerged in domestic cattle and bison herds in that area. Given the scientific and technological advances in two decades since that first report, Revisiting Brucellosis in the Greater Yellowstone Area explores the factors associated with the increased transmission of brucellosis from wildlife to livestock, the recent apparent expansion of brucellosis in non-feedground elk, and the desire to have science inform the course of any future actions in addressing brucellosis in the GYA.
