AN ECOLOGICAL CHARACTERIZATION STUDY OF THE CHENIER
PLAIN COASTAL ECOSYSTEM OF LOUISIANA AND TEXAS was prepared
for the National Coastal Ecosystems Team, Office of Biological Services, U.S.
Fish and Wildlife Service. James G. Gosselink, Louisiana State University, was
principal investigator. Funding was provided by the Office of Research and
Development, U.S. Environmental Protection Agency.

The Biological Services Program was established within the U.S. Fish and Wildlife
Service to supply scientific information and methodologies on key environmental issues
that impact fish and wildlife resources and their supporting ecosystems. The mission of
the program is as follows:

Index Maps

¢ To strengthen the Fish and Wildlife Service in its role as a primary source of
information on national fish and wildlife resources, particularly in respect to
environmental impact assessment.

© To gather, analyze, and present information that will aid decisionmakers in the
identification and resolution of problems associated with major changes in
land and water use.

e To provide better ecological information and evaluation for Department of the
Interior development programs, such as those relating to energy develop-
ment.

Information developed by the Biological Services Program is intended for use in the
planning and decisionmaking process to prevent or minimize the impact of development
on fish and wildlife. Research activities and technical assistance services are based on
analysis of the issues, a determination of the decisionmakers involved and their informa-
tion needs, and an evaluation of the state of the art to identify information gaps and
determine priorities. This is a strategy that will ensure that the products produced are
disseminated are timely and useful.

Projects have been initiated in the following areas: coal extraction and conversion;
power plants, geothermal, mineral, and oil-shale development; water resource analysis,
including stream alterations and western water allocation; coastal ecosystems and Outer
Continental Shelf development; and systems inventory, including National Wetland In-
ventory, habitat classification and analysis, and information transfer.

The Biological Services Program consists of the Office of Biological Services in
Washington, D.C., which is responsible for overall planning and management; National
Teams, which provide the Program’s central scientific and technical expertise and arrange
for contracting biological services studies with states, universities, consulting firms, and
others; Regional Staff, who provide a link to problems at the operating level; and staff at
certain Fish and Wildlife Service research facilities, who conduct in-house research
studies.
