Masked Bobwhite Biology And Conservation

Ranching is as much a part of the West as its wide-open spaces. The mystique of rugged individualism has sustained this activity well past the frontier era and has influenced how we viewÑand valueÑthose open lands. Nathan Sayre now takes a close look at how the ranching ideal has come into play in the conversion of a large tract of Arizona rangeland from private ranch to National Wildlife Refuge. He tells how the Buenos Aires Ranch, a working operation for a hundred years, became not only a rallying point for multiple agendas in the "rangeland conflict" after its conversion to a wildlife refuge but also an expression of the larger shift from agricultural to urban economies in the Southwest since World War II. The U.S. Fish and Wildlife Service bought the Buenos Aires Ranch in 1985, removed all livestock, and attempted to restore the land to its "original" grassland in order to protect an endangered species, the masked bobwhite quail. Sayre examines the history of the ranch and the bobwhite together, exploring the interplay of social, economic, and ecological issues to show how ranchers and their cattle altered the landÑfor better or worseÑduring a century of ranching and how the masked bobwhite became a symbol for environmentalists who believe that the removal of cattle benefits rangelands and wildlife. Sayre evaluates both sides of the Buenos Aires controversyÑfrom ranching's impact on the environment to environmentalism's sometimes misguided efforts at restorationÑto address the complex and contradictory roles of ranching, endangered species conservation, and urbanization in the social and environmental transformation of the West. He focuses on three dimensions of the Buenos Aires story: the land and its inhabitants, both human and animal; the role of government agencies in shaping range and wildlife management; and the various species of capitalÑeconomic, symbolic, and bureaucraticÑthat have structured the activities of ranchers, environmentalists, and government officials. The creation of the Buenos Aires National Wildlife Refuge has been a symbolic victory for environmentalists, but it comes at the cost of implicitly legitimizing the ongoing fragmentation and suburbanization of Arizona's still-wild rangelands. Sayre reveals how the polarized politics of "the rangeland conflict" have bound the Fish and Wildlife Service to a narrow, ineffectual management strategy on the Buenos Aires, with greater attention paid to increasing tourism from birdwatchers than to the complex challenge of restoring the masked bobwhite and its habitat. His findings show that the urban boom of the late twentieth century echoed the cattle boom of a century beforeÑcapitalizing on land rather than grass, humans rather than cattleÑin a book that will serve as a model for restoration efforts in any environment.

Conservation genetics focuses on understanding the role of genetic variation for population persistence. This book is about the methods used to study genetic variation in endangered species and whether genetic variation matters in the extinction of species.

In just the last few years, behavioral ecologists have begun to address issues in conservation biology. This volume is the first attempt to link these disciplines formally. Here leading researchers explore current topics in conservation biology and discuss how behavioral ecology can contribute to a greater understanding of conservation problems and conservation intervention programs. In each chapter, the authors identify a conservation issue, review the ways it has been addressed, review behavioral ecological data related to it, including their own, evaluate the strengths and weaknesses of the behavioral ecological approach, and put forward specific conservation recommendations. The chapters juxtapose different studies on a wide variety of taxonomic groups. A number of common themes emerge, including the ways in which animal mating systems affect population persistence, the roles of dispersal and inbreeding avoidance for topics such as reserve design and effective population size, the key role of humans in conservation issues, and the importance of baseline data for conservation monitoring and modeling attempts. Each chapter sheds new light on conservation problems, generates innovative avenues of interdisciplinary research, and shows how conservation-minded behavioral ecologists can apply their expertise to some of the most important questions we face today.
