"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.
Wetlands are a valuable natural resource, yet over 200,000 acres are destroyed in the United States per year. This book examines whether states should assume the role of protecting wetlands rather than the federal government.
Because wetlands provide valuable functions, the administration set a national goal of no net loss of wetlands in 1989. The Clean Water Act prohibits the discharge of dredged or fill material into waters, which include wetlands, without a permit from the U.S. Army Corps of Engineers (ACE). The ACE can require compensatory mitigation, such as restoring a former wetland, as a condition of a permit when the loss of wetlands is unavoidable. This report reviews the: (1) guidance the ACE has issued for overseeing compensatory mitigation; (2) extent to which the ACE oversees compensatory mitigation; & (3) enforcement actions the ACE can take if required mitigation is not performed & the extent to which it takes these actions.
