Relicts of a Beautiful Sea


Book Description

Along a tiny spring in a narrow canyon near Death Valley, seemingly against all odds, an Inyo Mountain slender salamander makes its home. "The desert," writes conservation biologist Christopher Norment, "is defined by the absence of water, and yet in the desert there is water enough, if you live properly." Relicts of a Beautiful Sea explores the existence of rare, unexpected, and sublime desert creatures such as the black toad and four pupfishes unique to the desert West. All are anomalies: amphibians and fish, dependent upon aquatic habitats, yet living in one of the driest places on earth, where precipitation averages less than four inches per year. In this climate of extremes, beset by conflicts over water rights, each species illustrates the work of natural selection and the importance of conservation. This is also a story of persistence--for as much as ten million years--amid the changing landscape of western North America. By telling the story of these creatures, Norment illustrates the beauty of evolution and explores ethical and practical issues of conservation: what is a four-inch-long salamander worth, hidden away in the heat-blasted canyons of the Inyo Mountains, and what would the cost of its extinction be? What is any lonely and besieged species worth, and why should we care?

Battle Against Extinction


Book Description

In 1962 the Green River was poisoned and its native fishes killed so that the new Flaming Gorge Reservoir could be stocked with non-native game fishes for sportsmen. This incident was representative of water management in the West, where dams and other projects have been built to serve human needs without consideration for the effects of water diversion or depletion on the ecosystem. Indeed, it took a Supreme Court decision in 1976 to save Devils Hole pupfish from habitat destruction at the hands of developers. Nearly a third of the native fish fauna of North America lives in the arid West; this book traces their decline toward extinction as a result of human interference and the threat to their genetic diversity posed by decreases in their populations. What can be done to slow or end this tragedy? As the most comprehensive treatment ever attempted on the subject, Battle Against Extinction shows how conservation efforts have been or can be used to reverse these trends. In covering fishes in arid lands west of the Mississippi Valley, the contributors provide a species-by-species appraisal of their status and potential for recovery, bringing together in one volume nearly all of the scattered literature on western fishes to produce a monumental work in conservation biology. They also ponder ethical considerations related to the issue, ask why conservation efforts have not proceeded at a proper pace, and suggest how native fish protection relates to other aspects of biodiversity planetwide. Their insights will allow scientific and public agencies to evaluate future management of these animal populations and will offer additional guidance for those active in water rights and conservation biology. First published in 1991, Battle Against Extinction is now back in print and available as an open-access e-book thanks to the Desert Fishes Council.

The Thin Green Line


Book Description

When first established decades ago, most U.S. military installations were far from major cities and towns. That is no longer true. A growing population and changing land development patterns over the past several decades have led to lands vital to military readiness being surrounded by urban, suburban, and other types of development. Such development, especially large residential tracts, can limit the installation's operational capability. Complaints about noise, dust, and smoke from aircraft, weapons, and vehicles force commanders to curtail training of certain types or during certain hours. As development destroys or displaces native species of plants and animals, military posts become their critical refuge, and their presence further restricts military operations. These constraints have been so severe in some cases that installations have had to close. Such pressures are called encroachment. Encroachment can be defined as issues external to military operations that affect military installation testing, training, and other operations and overall military readiness. Recognizing the gravity of the problem, Congress provided legislative authority to allow military departments to partner with government or private organizations to establish buffer areas near training and testing areas. The Office of the Secretary of Defense(OSD) created the Conservation Partnering Program (now known as the Readiness and Environmental Protection Initiative (REPI)2) to implement this authority.
