Available in PDF, EPUB and Kindle. Book excerpt: Wetlands Lost. The 1,879 thousand hectares of coastal wetlands in the Gulf of Mexico (GOM) comprise 58% of the U.S. coastal wetland total (Turner and Gosselink 1975). These wetlands occur in every GOM state, although two-thirds of the GOM total are in Louisiana, and are typically associated with estuaries, bays, rivers, and the lee-side of barrier islands. The objective of this book is to facilitate and encourage the restoration of these and other wetlands by reviewing the details of construction and costs (which can range from $1 to $45,000 per hectare), and by evaluating case studies for levels of success. Each approach is presented in brief chapters outlining the essential points of "what, why, and how" the approach can be planned and implemented. The driving purpose, or goal, of this book is to accelerate regional wetland gains and to promote cost-effective practices in wetland restoration. Why do we think that this book is necessary? The area of wetlands has been diminishing almost everywhere for the last several hundred years, but particularly this century, as the twin juggernauts of population growth and per capita resource exploitation expanded. In 1927, as the Great Depression in the U.S. was about to start, there were 2 billion people on the planet. There were 6 billion people on the Earth in the year 2000 and by 2054 there will be 9 billion. Two hundred years ago there were 89.5 million ha of wetlands in the contiguous 48 U.S. states (Dahl 1990). By 1997 this area had shrunk to 42.7 million ha (Dahl 2001). From the 1970s to the mid-1980s, the annual wetland loss rate was 117,400 ha (Dahl and Johnson 1991). The official national policy of "no net loss" may be why the wetland loss rate slowed to 23.7 thousand ha yr-1 from 1986 to 1997 (Dahl 2001). Although wetland loss rates have also declined in coastal Louisiana in recent years, Louisiana experienced particularly high coastal wetland loss rates of 12.5 thousand ha yr-1 (0.86% yr-1) from 1956 to 1978 (Baumann and Turner 1990). Thus, wetland loss has become a national concern (National Research Council 1991; Dahl 2001, National Research Council 2001) and particularly in the northern Gulf of Mexico. We hope to contribute to the reversal of these wetland losses by presenting wetland restoration and creation approaches appropriate for the Northern Gulf of Mexico, and perhaps elsewhere.

Available in PDF, EPUB and Kindle. Book excerpt: The study of estuaries and coasts has seen enormous growth in recent years, since changes in these areas have a large effect on the food chain, as well as on the physics and chemistry of the ocean. As the coasts and river banks around the world become more densely populated, the pressure on these ecosystems intensifies, putting a new focus on environmental, socio-economic and policy issues. Written by a team of international expert scientists, under the guidance of Chief Editors Eric Wolanski and Donald McClusky, the Treatise on Estuarine and Coastal Science, Ten Volume Set examines topics in depth, and aims to provide a comprehensive scientific resource for all professionals and students in the area of estuarine and coastal science Most up-to-date reference for system-based coastal and estuarine science and management, from the inland watershed to the ocean shelf Chief editors have assembled a world-class team of volume editors and contributing authors Approach focuses on the physical, biological, chemistry, ecosystem, human, ecological and economics processes, to show how to best use multidisciplinary science to ensure earth's sustainability Provides a comprehensive scientific resource for all professionals and students in the area of estuarine and coastal science Features up-to-date chapters covering a full range of topics

Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2000-10-31 with total page 862 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tidal salt marshes are viewed as critical habitats for the production of fish and shellfish. As a result, considerable legislation has been promulgated to conserve and protect these habitats, and much of it is in effect today. The relatively young science of ecological engineering has also emerged, and there are now attempts to reverse centuries-old losses by encouraging sound wetland restoration practices. Today, tens of thousands of hectares of degraded or isolated coastal wetlands are being restored worldwide. Whether restored wetlands reach functional equivalency to `natural' systems is a subject of heated debate. Equally debatable is the paradigm that depicts tidal salt marshes as the `great engine' that drives much of the secondary production in coastal waters. This view was questioned in the early 1980s by investigators who noted that total carbon export, on the order of 100 to 200 g m-2 y-1 was of much lower magnitude than originally thought. These authors also recognized that some marshes were either net importers of carbon, or showed no net exchange. Thus, the notion of `outwelling' has become but a single element in an evolving view of marsh function and the link between primary and secondary production. The `revisionist' movement was launched in 1979 when stable isotopic ratios of macrophytes and animal tissues were found to be `mismatched'. Some eighteen years later, the view of marsh function is still undergoing additional modification, and we are slowly unraveling the complexities of biogeochemical cycles, nutrient exchange, and the links between primary producers and the marsh/estuary fauna. Yet, since Teal's seminal paper nearly forty years ago, we are not much closer to understanding how marshes work. If anything, we have learned that the story is far more complicated than originally thought. Despite more than four decades of intense research, we do not yet know how salt marshes function as essential habitat, nor do we know the relative contributions to secondary production, both in situ or in the open waters of the estuary. The theme of this Symposium was to review the status of salt marsh research and revisit the existing paradigm(s) for salt marsh function. Challenge questions were designed to meet the controversy head on: Do marshes support the production of marine transient species? If so, how? Are any of these species marsh obligates? How much of the production takes place in situ versus in open waters of the estuary/coastal zone? Sessions were devoted to reviews of landmark studies, or current findings that advance our knowledge of salt marsh function. A day was also devoted to ecological engineering and wetland restoration papers addressing state-of-the-art methodology and specific case histories. Several challenge papers arguing for and against our ability to restore functional salt marshes led off each session. This volume is intended to serve as a synthesis of our current understanding of the ecological role of salt marshes, and will, it is hoped, pave the way for a new generation of research.
