Book Description
"Wetlands" has become a hot word in the current environmental debate. But what does it signify? In 1991, proposed changes in the legal definities of wetlands stirred controversy and focused attention on the scientific and economic aspects of their management. This volume explores how to define wetlands. The committee--whose members were drawn from academia, government, business, and the environmental community--builds a rational, scientific basis for delineating wetlands in the landscape and offers recommendations for further action. Wetlands also discusses the diverse hydrological and ecological functions of wetlands, and makes recommendations concerning so-called controversial areas such as permafrost wetlands, riparian ecosystems, irregularly flooded sites, and agricultural wetlands. It presents criteria for identifying wetlands and explores the problems of applying those criteria when there are seasonal changes in water levels. This comprehensive and practical volume will be of interest to environmental scientists and advocates, hydrologists, policymakers, regulators, faculty, researchers, and students of environmental studies.

Book Description
This book brings together in compact form a broad scientific and sociopolitical view of US wetlands. This primer lays out the science and policy considerations to help in navigating this branch of science that is so central to conservation policy, ecosystem science and wetland regulation. It gives explanations of the attributes, functions and values of our wetlands and shows how and why public attitudes toward wetlands have changed, and the political, legal, and social conflicts that have developed from legislation intended to stem the rapid losses of wetlands. The book describes the role of wetland science in facilitating the evolution of a rational and defensible system for regulating wetlands and will shed light on many of the problems and possibilities facing those who quest to protect and conserve our wetlands.

Book Description
New focused text introduces readers to wetland ecosystems and systems approaches to studying wetlands With its comprehensive coverage of wetland science, management, and restoration, Mitsch and Gosselink's Wetlands has been the premier reference on wetlands for more than two decades. Now, the coverage of specific wetland ecosystem types from earlier editions of this acclaimed work has been updated, revised, and supplemented with additional content in order to create this new text focusing exclusively on wetland ecosystems. This book now complements Wetlands, Fourth Edition. Following an introduction to ecosystems in general and wetland ecosystems in particular, Wetland Ecosystems examines the major types of wetlands found throughout the world: coastal wetlands, freshwater marshes and forested swamps, and peatlands. The final chapter reviews three fundamental systems approaches to studying wetlands: mesocosms, full-scale experimental ecosystems, and mathematical modeling. This new text features: Updated descriptions of the hydrology, biogeochemistry, and biology of the main types of wetlands found in the world New content introducing general ecosystems, wetland ecosystems, whole ecosystem and mesocosm experiments with wetlands, and systems ecology and modeling A detailed description of the ecosystem services provided by wetlands A broad international scope, including many examples of wetlands located outside North America Two new coauthors offering new perspectives and additional insights into the latest ecosystem and modeling techniques An abundance of illustrations helps readers understand how different biological communities and the abiotic environment in wetland ecosystems interact and function. Tables and text boxes provide at-a-glance summaries of key information. Lastly, each chapter concludes with a list of recommended readings. This text has been designed as an introduction for students and professionals in wetland ecology and management, general ecology, environmental science, and natural resource management.

Book Description
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.
