"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.
A major source of land use policy controversy in the United States and worldwide, for at least a decade, wetlands are the subject of a rapidly growing literature across many disciplines. This bibliography brings together the salient works on the economic and related restoration and delineation aspects of wetland resources. Covering recent literature, it includes 80 entries on methodological aspects of wetland economics and 195 entries on empirical issues, 74 entries on wetland restoration/creation economics, and 111 entries on delineation/definition issues. Each of the four major sections begins with a short overview of the literature, followed by an annotated bibliography. Most of the literature covered pertains to the United States and Canada, but relevant international works are included. Although most of the literature was published from 1989 to 1993, some earlier works are identified, and some early 1994 publications are included as well.
