"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.

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 explains how with careful planning and design, the functions and performance of constructed wetlands can provide a huge range of benefits to humans and the environment. It documents the current designs and specifications for free water surface wetlands, horizontal and vertical subsurface flow wetlands, hybrid wetlands and bio retention basins; and explores how to plan, engineer, design and monitor these natural systems. Sections address resource management (landscape planning), technical issues (environmental engineering and botany), recreation and physical design (landscape architecture), and biological systems (ecology). Site and municipal scale strategies for flood management, storm-water treatment and green infrastructure are illustrated with case studies from the USA, Europe and China, which show how these principles have been put into practice. Written for upper level students and practitioners, this highly illustrated book provides designers with the tools they need to ensure constructed wetlands are sustainably created and well manage

Wetland and Stream Rapid Assessments: Development, Validation, and Application describes the scientific and environmental policy background for rapid wetland and stream assessments, how such assessment methods are developed and statistically verified, and how they can be used in environmental decision-making—including wetland and stream permitting. In addition, it provides several case studies of method development and use in various parts of the world. Readers will find guidance on developing and testing such methods, along with examples of how these methods have been used in various programs across North America. Rapid wetland and stream functional assessments are becoming frequently used methods in federal, state and local environmental permitting programs in North America. Many governments are interested in developing new methods or improving existing methods for their own jurisdictions. This book provides an ideal guide to these initiatives. - Offers guidance for the use and evaluation of rapid assessments to developers and users of these methods, as well as students of wetland and stream quality - Contains contributions from sources who are successful in academia, industry and government, bringing credibility and relevance to the content - Includes a statistically-based approach to testing the validity of the rapid method, which is very important to the usefulness and defensibility of assessment methods

In the name of agriculture, urban growth, and disease control, humans have drained, filled, or otherwise destroyed nearly 87 percent of the world’s wetlands over the past three centuries. Unintended consequences include biodiversity loss, poor water quality, and the erosion of cultural sites, and only in the past few decades have wetlands been widely recognized as worth preserving. Emily O’Gorman asks, What has counted as a wetland, for whom, and with what consequences? Using the Murray-Darling Basin—a massive river system in eastern Australia that includes over 30,000 wetland areas—as a case study and drawing on archival research and original interviews, O’Gorman examines how people and animals have shaped wetlands from the late nineteenth century to today. She illuminates deeper dynamics by relating how Aboriginal peoples acted then and now as custodians of the landscape, despite the policies of the Australian government; how the movements of water birds affected farmers; and how mosquitoes have defied efforts to fully understand, let alone control, them. Situating the region’s history within global environmental humanities conversations, O’Gorman argues that we need to understand wetlands as socioecological landscapes in order to create new kinds of relationships with and futures for these places.

Wetlands throughout the world, including those described in this book are among the most sensitive and vulnerable ecosystems. They are critical habitats to the world’s migratory birds and a broad range of endangered mammal, reptile, amphibian, and plant species. They provide a broad range of flood storage, pollution control, water supply, ecotourism functions to indigenous peoples and country populations as a whole. They are also at the center of severe land and water use conflicts. These are conflicts between counties where wetland resources or the water supplies required for such resources involve more than one country. These are conflicts in use such as conflicts between habitat protection and charcoal production in mangroves. These are conflicts between groups of peoples such as indigenous peoples and hydropower advocates. Many wetlands have already been destroyed by water extractions, dams, levees, channelization, and fills. Others have been degraded by water pollution, overfishing and overhunting, timber harvest, and a host of other activities. This book describes these conflicts and international policies and institutions developed to protect and manage wetland resources. Most of the broader literature and other books on wetlands focuses on wildlife. Wildlife is described in the case studies, which follow. But, Richard Smardon provides us with more. He traces the history of conflicts and the development of policies and insti- tions to protect and manage wetland resources.

This book contains papers presented at the International Workshop on Tropical Wetlands, held in Banjarmasin, Indonesia. This workshop discussed wetland mapping and characterization as well as wetland management for sustainable agriculture. This volume contains selected papers on tropical wetlands, more specifically, peatland, tidal land, and acid sulphate soils. This book presents an international overview of wetland and peatland mapping experiences from Indonesia, Congo, Brazil, Australia, and Scotland. Several innovative techniques are discussed, including integrated digital soil mapping and remote sensing techniques, as well as geodatabase processing and field surveying. This book further discussed tropical wetland management for agriculture as practiced in Indonesia, Vietnam, and Thailand. The contents of this book are suitable and should be a good reference for those who are involved in research, development, and management of tropical wetland, including academics, soil scientists, environmentalists, researchers, agriculturists, students, agri-businessmen, policy makers, land managers and farmers.
