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

Download or read book Restoration of Aquatic Ecosystems written by National Research Council and published by National Academies Press. This book was released on 1992-01-01 with total page 580 pages. 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.

Available in PDF, EPUB and Kindle. Book excerpt: “Wetland Habitats of North America is essential reading for everyone who studies, manages, or visits North American wetlands. It fills an important void in the wetland literature, providing accessible and succinct descriptions of all of the continent’s major wetland types.” Arnold van der Valk, Iowa State University “Batzer and Baldwin have compiled the most comprehensive compendium of North American wetland habitats and their ecology that is presently available—a must for wetland scientists and managers.” Irving A. Mendelssohn, Louisiana State University "If you want to gain a broad understanding of the ecology of North America’s diverse wetlands, Wetland Habitats of North America is the book for you. Darold Batzer and Andrew Baldwin have assembled an impressive group of regional wetland scientists who have produced a virtual encyclopedia to the continent’s wetlands. Reading the book is like a road trip across the Americas with guided tours of major wetland types by local experts. Your first stop will be to coastal wetlands with eight chapters covering tidal wetlands along the Atlantic, Gulf, and Pacific coasts. Then you’ll travel inland where you can visit any or all of 18 types ranging from bottomland swamps of the Southeast to pothole marshes of the Northern Prairies to montane wetlands of the Rockies to tropical swamps of Central America and desert springs wetlands. All in one book—I’m impressed! Every wetlander should add this book to her or his swampland library. Ralph Tiner, University of Massachusetts–Amherst

This book was released on 2013-06-10 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report covers the mid-1970'2 to the mid-1980's, a period in which Federal, State, and local government programs and policies began to affect wetland use and conversion. For this reason, there has been intense interest by the scientific and governmental communities in these updated wetlands statistics. Although the data contained in this report generally predates more recent wetlands legislation, they provide information that can help to assess the effectiveness of public policies and programs that have been intended to reduce the loss of the Nation's remaining wetlands.

This book was released on 2015-02-13 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: For over half a century the Fish and Wildlife Service has been monitoring wetland trends of the nation. In 1956, the first report on wetland status and classification provided indications that wetland habitat for migratory waterfowl had experienced substantial declines (Shaw and Fredine 1956).Over the intervening 51 years, the Fish and Wildlife Service has implemented a scientifically based process to periodically measure wetland status and trends in the conterminous United States. The Fish and Wildlife Service's Wetlands Status and Trends study was developed specifically for monitoring the nation's wetland area using a single, consistent definition and study protocol. The Fish and Wildlife Service has specialized knowledge of wetland habitats, classification, and ecological changes and has used that capability to conduct a series of wetland monitoring studies that document the status and trends of our nation's wetlands. This report is the latest in that series of scientific studies.
