This benchmark volume documents in comprehensive detail a major environmental crisis: rapidly declining amphibian populations and the disturbing developmental problems that are increasingly prevalent within many amphibian species. Horror stories on this topic have been featured in the scientific and popular press over the past fifteen years, invariably asking what amphibian declines are telling us about the state of the environment. Are declines harbingers of devastated ecosystems or simply weird reflections of a peculiar amphibian world? This compendium—presenting new data, reviews of current literature, and comprehensive species accounts—reinforces what scientists have begun to suspect, that amphibians are a lens through which the state of the environment can be viewed more clearly. And, that the view is alarming and presages serious concerns for all life, including that of our own species. The first part of this work consists of more than fifty essays covering topics from the causes of declines to conservation, surveys and monitoring, and education. The second part consists of species accounts describing the life history and natural history of every known amphibian species in the United States.

The Greater Yellowstone Ecosystem (GYE) contains the headwaters of the Missouri, Snake and Green Rivers. Average annual discharge from the GYE into these rivers totals 16.2 million acre-feet (5,280,000,000,000 gallons). Furthermore, the rivers and lakes of the GYE are internationally famous for their recreational and scenic values. However, trends in aquatic species status and watershed condition in the GYE have not been quantified. The purpose of this study is to compile and analyze existing ecosystem-scale data on the condition of aquatic and riparian habitats and salmonid fishes.

The Clean Water Act (CWA) requires that wetlands be protected from degradation because of their important ecological functions including maintenance of high water quality and provision of fish and wildlife habitat. However, this protection generally does not encompass riparian areasâ€"the lands bordering rivers and lakesâ€"even though they often provide the same functions as wetlands. Growing recognition of the similarities in wetland and riparian area functioning and the differences in their legal protection led the NRC in 1999 to undertake a study of riparian areas, which has culminated in Riparian Areas: Functioning and Strategies for Management. The report is intended to heighten awareness of riparian areas commensurate with their ecological and societal values. The primary conclusion is that, because riparian areas perform a disproportionate number of biological and physical functions on a unit area basis, restoration of riparian functions along America's waterbodies should be a national goal.

In 1991, the Herpatology Laboratory at Idaho State University began a collaborative project with the National Park Service and U.S. Fish and Wildlife Service to assess the occurrence and status of amphibians in the Greater Yellowstone Ecosystem. The program was expanded in 2000 and was fully implemented by 2007.

The demand for water resulting from massive population and economic growth in the southwestern U.S. overwhelmed traditional uses of riparian areas. As a consequence, many of these uniquely-structured ecosystems have been altered or destroyed. Within recent years people have become increasingly aware of the many uses and benefits of riparian zones a
