This volume is the result of a coordinated effort to compile the most up-to-date information available on wetland resources. Although much has been written about the biological aspects of wetlands, much less has been written about the hydrology and the non-habitat functions of wetlands. This volume presents an overview of wetland resources from many different perspectives.
The first part of this volume, "Overview of Wetland Resources," discusses wetland resources from a national perspective and provides background information for the State summaries section. This section contains articles on the technical, management and research, and restoration, creation, and recovery aspects of wetland resources. These articles relate the history of wetlands in the United States; the definition of wetlands and a description of the U.S. Fish and Wildlife Service Classification System (Cowardin and others, 1979); hydrologic and water-quality factors that affect the distribution of wetlands and related functions commonly attributed to wetlands; the role of wetlands as habitat for birds; the roles of Federal agencies in wetland protection legislation and research; progress in inventory and mapping of wetlands; techniques for evaluating wetlands; human attempts to restore damaged wetlands and create new ones; and the recovery of wetlands following natural disasters.
The second part, "State Summaries of Wetland Resources," describes wetlands of each State, the District of Columbia (combined with Maryland), Puerto Rico, the U.S. Virgin Islands, and the Western Pacific Islands. Each State summary discusses wetlands in terms of value, types and distribution, hydrologic setting, and trends in acreage from predevelopment to modern times. Each State summary also provides an overview of public- and private-sector wetland-conservation efforts in that State and a table showing the wetland-related responsibilities of principal government agencies and private organizations within the State. Illustrations include a map depicting the areal distribution of principal wetlands and selected related features such as ecoregions, physiography, precipitation, runoff, evaporation, or other physical or climatic features that influence the presence or distribution of wetlands in that State. Some of the State summaries include a map or cross section depicting the hydrologic setting of wetlands and (or) a map showing predevelopment wetland distribution.
To supplement the information provided in this volume, bibliographic references are listed at the end of each article and State summary. An extensive list of suggested references for more information about topics discussed in the "Overview of Wetland Resources" is available in U.S. Geological Survey Open-File Report 96-169. This report also is available online at http://water.usgs.gov/nwsum/bib/bib.html. Most technical terms are defined in the glossary at the end of this volume, and a conversion table of water measurements precedes the glossary.
