Outlines the role of science in restoring or otherwise altering unwanted downstream effects of dams, including eroding river banks, changes in waterfowl habitat, threats to safe recreational use, and the loss of river sand bars, examining seven selected areas of the country -- the upper Salt River in central Arizona; the Snake River in Idaho, Oregon and Washington; the Rio Grande in New Mexico and Texas; the Chattahoochee River in Georgia; the Platte River in Wyoming, Colorado and Nebraska; the Green River in Utah; and the Colorado River in Arizona -- to focus on specific downstream effects of dams and the management issues related to their operation.

Running waters are enormously diverse, ranging from torrential mountain brooks, to large lowland rivers, to great river systems whose basins occupy subcontinents. While this diversity makes river ecosystems seem overwhelmingly complex, a central theme of this volume is that the processes acting in running waters are general, although the settings are often unique. The past two decades have seen major advances in our knowledge of the ecology of streams and rivers. New paradigms have emerged, such as the river continuum and nutrient spiraling. Community ecologists have made impressive advances in documenting the occurrence of species interactions. The importance of physical processes in rivers has attracted increased attention, particularly the areas of hydrology and geomorphology, and the inter-relationships between physical and biological factors have become better understood. And as is true for every area of ecology during the closing years of the twentieth century it has become apparent that the study of streams and rivers cannot be carried out by excluding the role of human activities, nor can we ignore the urgency of the need for conservation. These developments are brought together in Stream Ecology: Structure and function of running waters, designed to serve as a text for advanced undergraduate and graduate students, and as a reference book for specialists in stream ecology and related fields.

Safe Passages brings together in a single volume the latest information on the emerging science of road ecology as it relates to mitigating interactions between roads and wildlife. This practical handbook of tools and examples is designed to assist individuals and organizations thinking about or working toward reducing road-wildlife impacts. The book provides: an overview of the importance of habitat connectivity with regard to roads current planning approaches and technologies for mitigating the impacts of highways on both terrestrial and aquatic species different facets of public participation in highway-wildlife connectivity mitigation projects case studies from partnerships across North America that highlight successful on-the-ground implementation of ecological and engineering solutions recent innovative highway-wildlife mitigation developments Detailed case studies span a range of scales, from site-specific wildlife crossing structures, to statewide planning for habitat connectivity, to national legislation. Contributors explore the cooperative efforts that are emerging as a result of diverse organizations—including transportation agencies, land and wildlife management agencies, and nongovernmental organizations—finding common ground to tackle important road ecology issues and problems. Safe Passages is an important new resource for local-, state-, and national-level managers and policymakers working on road-wildlife issues, and will appeal to a broad audience including scientists, agency personnel, planners, land managers, transportation consultants, students, conservation organizations, policymakers, and citizens engaged in road-wildlife mitigation projects.

For more than 100 years, the Coeur d' Alene River Basin has been known as "The Silver Valley" for being one of the most productive silver, lead, and zinc mining areas in the United States. Over time, high levels of metals (including lead, arsenic, cadmium, and zinc) were discovered in the local environment and elevated blood lead levels were found in children in communities near the metal-refining and smelter complex. In 1983, the U.S. Environmental Protection Agency (EPA) listed a 21-square mile mining area in northern Idaho as a Superfund site. EPA extended those boundaries in 1998 to include areas throughout the 1500-square mile area Coeur d'Alene River Basin project area. Under Superfund, EPA has developed a plan to clean up the contaminated area that will cost an estimated $359 million over 3 decades-and this effort is only the first step in the cleanup process. Superfund and Mining Megasites: Lessons from Coeur d'Alene River Basin evaluates the issues and concerns that have been raised regarding EPA's decisions about cleaning up the area. The scientific and technical practices used by EPA to make decisions about human health risks at the Coeur d'Alene River Basin Superfund site are generally sound; however, there are substantial concerns regarding environmental protection decisions, particularly dealing with the effectiveness of long-term plans.
