"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 committeeâ€"whose members were drawn from academia, government, business, and the environmental communityâ€"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.
The single most important book on wetlands, newly expanded and updated Wetlands is the definitive guide to this fragile ecosystem, providing the most comprehensive coverage and in-depth information available in print. Recently updated and expanded, this latest edition contains brand new information on Wetland Ecosystem Services and an updated discussion on Wetland, Carbon, and Climate Change and Wetland Creation and Restoration. Due to popular demand, the authors have brought back five streamlined chapters on wetland ecosystems that had been removed from previous editions, and provided more robust ancillary materials including an online color photo gallery, PowerPoint slides, and several video case studies. As nature's kidneys, wetland ecosystems help the environment process toxins and excess fertilizers and maintain the relative health of our aquatic ecosystems. As the understanding of their importance grows, their management and ecology have gained increased attention and have become an area of professional specialization over the past two decades. This book gives readers a solid understanding of wetlands, how they work, what they do, and why the Earth can't live without them. Understand wetlands' role in the ecosystem, from local to global scales Appreciate the fact that wetlands may be the most logical and economical way to sequester carbon from the atmosphere Discover the unique characteristics that make wetlands critically important for improving water quality, reducing storm and flood damage, and providing habitat to support biodiversity Learn how wetlands are being managed or destroyed around the globe but also how we can create and restore them Examine the ways in which climate change is affecting wetland ecosystems and wetland ecosystems affect climate change Wetlands are crucial to the health of the planet, and we've only begun to realize the magnitude of the damage that has already been done as we scramble to save them. A generation of ecologists, ecological engineers, land use planners, and water resource managers worldwide owe their knowledge of the wetlands to this book – for the next generation to follow in their footsteps, Wetlands 5th edition is the quintessential guide to these critical systems.
Regulations require that development projects in wetland areas restoreor replace lost wetland functions and values. But you can avoid or minimizeexpenses and repeated delays - this new book provides the most comprehensive, in-depth treatment of wetland mitigation options available! Written in plain English, not legalese, this practical reference provides explanations ofthe relevant regulations, and guidance on mitigation requirements and thepermitting process. You'll learn everything you need to know about evaluating, selecting, negotiating and implementing the various mitigation measuresavailable to avoid, minimize, or compensate for land use development impacts to wetlands. The book also includes helpful tables and checklists, numerous"real life" mitigation case studies, and several useful appendices. Chapters include: Wetland Functions and Values; Wetland Identification; Wetlands Regulations; Wetland Permitting; Wetland Mitigation Compliance; Wetland Mitigation Options; Wetland Mitigation Banking; Wetland MitigationBanking Guidance; Wetland Mitigation Case Studies. Appendices include: U.S. EPA, Army Corps of Engineers, and State WetlandOffices; Clinton Administration's Wetlands Plan; Funding and Technical Assistancefor Wetland Acquisition and Restoration; and more.
This is the first comprehensive environmental history of California’s Great Central Valley, where extensive freshwater and tidal wetlands once provided critical habitat for tens of millions of migratory waterfowl. Weaving together ecology, grassroots politics, and public policy, Philip Garone tells how California’s wetlands were nearly obliterated by vast irrigation and reclamation projects, but have been brought back from the brink of total destruction by the organized efforts of duck hunters, whistle-blowing scientists, and a broad coalition of conservationists. Garone examines the many demands that have been made on the Valley’s natural resources, especially by large-scale agriculture, and traces the unforeseen ecological consequences of our unrestrained manipulation of nature. He also investigates changing public and scientific attitudes that are now ushering in an era of unprecedented protection for wildlife and wetlands in California and the nation.
Global Biodiversity is the most comprehensive compendium of conservation information ever published. It provides the first systematic report on the status, distribution, management, and utilisation of the planet's biological wealth.
