Wetlands in a Dry Land


Book Description

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


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.




Restoration of Aquatic Ecosystems


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.




America's Wetland


Book Description

With America's Wetland, award-winning photographer Bevil Knapp and veteran reporter Mike Dunne sound the clarion call of the catastrophic effects of Louisiana's vanishing coastline -- not just for Louisiana but for the nation and the world. This vital landscape known as America's Wetland is currently disappearing at a rate of twenty-four square miles per year and could lose another five to seven hundred square miles in the next fifty years if no action is taken. New Orleans could become "America's Atlantis," one of the country's unique cultures lost forever. Knapp's beautiful, sometimes startling photographs and Dunne's incisive commentary bring the urgency of this problem into full view. Documented here is a way of life that is quickly waning. Fishermen, oyster farmers, cattle ranchers, oil industry workers, shipbuilders, and tugboat captains are all heavily dependent on Louisiana's coastal territory in bringing the people of the United States a host of products and services sometimes taken for granted. Home to nearly two million residents, the state's wetland serves as protection from hurricanes and storm surges and acts as a buffer for the city of New Orleans, identified by the National Hurricane Center as the city most threatened by the loss of America's Wetland. The book makes clear that as coastal erosion in Louisiana worsens at an alarming rate, the nation's economic and energy security is put at ever-higher risk and the environmental repercussions become unthinkable. Aerial photographs show how the oil and gas infrastructure is becoming increasingly exposed to the Gulf. Wells, pipelines, ports, roads, and levees that are key to delivering energy to the nation have been made vulnerable. Louisiana wetlands are the natural nursery ground for much of the country's seafood and the wintering habitat for more than five million waterfowl and migratory birds. Stunning photographs of owls, pelicans, egret, crab, crawfish, and alligators illustrate the vast array of wildlife whose home -- if not very survival -- is endangered by the possible collapse of this intricate ecosystem. America's Wetland not only maps the causes and effects of Louisiana's diminishing coast but also outlines restorative and conservation initiatives such as tree planting, rebuilding fisheries, and setting aside wildlife refuges. With the active support of all Americans, there is still hope that this imperiled border of the country can be saved.




Compensating for Wetland Losses Under the Clean Water Act


Book Description

Recognizing the importance of wetland protection, the Bush administration in 1988 endorsed the goal of "no net loss" of wetlands. Specifically, it directed that filling of wetlands should be avoided, and minimized when it cannot be avoided. When filling is permitted, compensatory mitigation must be undertaken; that is, wetlands must be restored, created, enhanced, and, in exceptional cases, preserved, to replace the permitted loss of wetland area and function, such as water quality improvement within the watershed. After more than a dozen years, the national commitment to "no net loss" of wetlands has been evaluated. This new book explores the adequacy of science and technology for replacing wetland function and the effectiveness of the federal program of compensatory mitigation in accomplishing the nation's goal of clean water. It examines the regulatory framework for permitting wetland filling and requiring mitigation, compares the mitigation institutions that are in use, and addresses the problems that agencies face in ensuring sustainability of mitigated wetlands over the long term. Gleaning lessons from the mixed results of mitigation efforts to date, the book offers 10 practical guidelines for establishing and monitoring mitigated wetlands. It also recommends that federal, state, and local agencies undertake specific institutional reforms. This book will be important to anyone seeking a comprehensive understanding of the "no net loss" issue: policy makers, regulators, environmental scientists, educators, and wetland advocates.




Multifunctional Wetlands


Book Description

This book describes how natural or constructed wetlands can be used to reduce pollution of freshwater and coastal ecosystems, while still preserving their biodiversity and ecological functions. Through a series of case histories described in 10 chapters in the monograph, the readers will gain an understanding of the opportunities, as well as the challenges associated with reducing point and non-point source pollution using natural, restored or constructed wetlands. The target audience will be water practitioners involved in projects utilizing integrated watershed management approaches to pollution abatement, as well as researchers who are designing projects focused on this topic.




The Fall and Rise of the Wetlands of California's Great Central Valley


Book Description

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.

From Swamp to Wetland


Book Description

This book chronicles the creation of Everglades National Park, the largest subtropical wilderness in the United States. This effort, which spanned 1928 to 1958, was of central importance to the later emergence of modern environmentalism. Prior to the park’s creation, the Everglades was seen as a reviled and useless swamp, unfit for typical recreational or development projects. The region’s unusual makeup also made it an unlikely candidate to become a national park, as it had none of the sweeping scenic vistas or geological monuments found in other nationally protected areas. Park advocates drew on new ideas concerning the value of biota and ecology, the importance of wilderness, and the need to protect habitats, marine ecosystems, and plant life to redefine the Everglades. Using these ideas, the Everglades began to be recognized as an ecologically valuable and fragile wetland—and thus a region in need of protective status. While these new ideas foreshadowed the later emergence of modern environmentalism, tourism and the economic desires of Florida’s business and political elites also impacted the park’s future. These groups saw the Everglades’ unique biology and ecology as a foundation on which to build a tourism empire. They connected the Everglades to Florida’s modernization and commercialization, hoping the park would help facilitate the state’s transformation into the Sunshine State. Political conservatives welcomed federal power into Florida so long as it brought economic growth. Yet, even after the park’s creation, conservative landowners successfully fought to limit the park and saw it as a threat to their own economic freedoms. Today, a series of levees on the park’s eastern border marks the line between urban and protected areas, but development into these areas threatens the park system. Rising sea levels caused by global warming are another threat to the future of the park. The battle to save the swamp’s biodiversity continues, and Everglades Park stands at the center of ongoing restoration efforts.
