Environmental problems in coastal ecosystems can sometimes be attributed to excess nutrients flowing from upstream watersheds into estuarine settings. This nutrient over-enrichment can result in toxic algal blooms, shellfish poisoning, coral reef destruction, and other harmful outcomes. All U.S. coasts show signs of nutrient over-enrichment, and scientists predict worsening problems in the years ahead. Clean Coastal Waters explains technical aspects of nutrient over-enrichment and proposes both immediate local action by coastal managers and a longer-term national strategy incorporating policy design, classification of affected sites, law and regulation, coordination, and communication. Highlighting the Gulf of Mexico's "Dead Zone," the Pfiesteria outbreak in a tributary of Chesapeake Bay, and other cases, the book explains how nutrients work in the environment, why nitrogen is important, how enrichment turns into over-enrichment, and why some environments are especially susceptible. Economic as well as ecological impacts are examined. In addressing abatement strategies, the committee discusses the importance of monitoring sites, developing useful models of over-enrichment, and setting water quality goals. The book also reviews voluntary programs, mandatory controls, tax incentives, and other policy options for reducing the flow of nutrients from agricultural operations and other sources.

This book focuses on the global threats to coastal environments from invasive, non-native species and examines how these alien biological species adversely alter landscapes and socioeconomic conditions as well as the psychological attitudes and perceptions of local inhabitants and tourists. Designed for the professional or specialist in marine science, coastal zone management, biology, and related disciplines, this volume appeals to those not only working directly with invasive flora and fauna species, but also those individuals involved in a wide array of coastal related fields. Examples and case studies of coastal invasive species are drawn from many different geographic areas worldwide, including North and South America, Europe, Oceania, the Caribbean, Southeast Asia, and Africa.

The ongoing growth of human populations within US coastal regions continues to increase habitat loss, eutrophication, organic loading, overfishing, and other anthropogenic stressors in estuarine waters. The National Estuarine Research Reserve System (NERRS) is a federally funded initiative that addresses these critical estuarine problems and coastal resource issues at 25 sites in 21 states. Now estuarine and watershed scientists, resource managers, community planners, and other professionals dealing with coastal zone issues have an expert resource describing the NERRS program, organization, goals, and management strategy. Estuarine Research, Monitoring, and Restoration first defines the components and technical aspects of the NERRS program, then provides valuable insight into the program through the presentation of six case studies of NERRS sites. This book examines estuarine problems including degraded water quality, reduction of biodiversity, and problematic invasive species, then analyzes the human impacts affecting estuaries. The comprehensive analysis of the six estuarine reserve locations characterizes each region's physical, chemical, and biological conditions from the perspective of the NERRS program. These case studies include a cross section of sites from three coasts, each study emphasizing the importance of unified efforts of government and citizens to successfully maintain the ecology of these critical areas.

Aldo Leopold, father of the "land ethic," once said, "The time has come for science to busy itself with the earth itself. The first step is to reconstruct a sample of what we had to begin with." The concept he expressedâ€"restorationâ€"is defined in this comprehensive new volume that examines the prospects for repairing the damage society has done to the nation's aquatic resources: lakes, rivers and streams, and wetlands. Restoration of Aquatic Ecosystems outlines a national strategy for aquatic restoration, with practical recommendations, and features case studies of aquatic restoration activities around the country. The committee examines: Key concepts and techniques used in restoration. Common factors in successful restoration efforts. Threats to the health of the nation's aquatic ecosystems. Approaches to evaluation before, during, and after a restoration project. The emerging specialties of restoration and landscape ecology.
