1981 - 8 Biological Services Program FWS/OBS-79/30 October 1981 An Introduction to the Environmental Literature of the Mississippi Deltaic Plain Region 44 ~.i u u u L !.~ Bureau of Land Management Fish and Wildlife Service 10 U.S. Department of the Interior D. 3 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 : To strengthen the Fish and Wildlife Service in its role as a primary source of information on national fish and wild- life resources, particularly in respect to environmental impact assessment . ~ To gather, analyze, and present information that will aid decisiolxnakers in the identification and resolution of problems associated with major changes in land and water use . ~ To provide better ecological information and evaluation for Department of the Interior development programs, such as those relating to energy development . 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 an analysis of the issues, a determination of the decisionmakers involved and their information needs, and an evaluation of the state of the art to identify information gaps and to determine priorities . This is a strategy that will ensure that the products produced and disseminated are timely and useful . Projects have been initiated in the following areas : coal extraction and conversion ; power plants ; geothermal, mineral and oil shale develop- ment ; water resource analysis, including stream alterations and western water allocation ; coastal ecosystems and Outer Continental Shelf develop- ment ; and systems inventory, including National Wetland Inventory, 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 Staffs, who provide a link to problems at the operating level ; and staffs at certain Fish and Wildlife Service research facilities, who conduct in-house research studies .

PREFACE This report is a review of selected environmental literature of the Mississippi Deltaic Plain Region . This review introduces some of the major ecosystem components and processes, describes oil and gas production activi- ties, and guides the reader to available literature . The seven chapters in this review and the number of references used for each are as follows : Introduction - 5 ; Geology - 147 ; Hydrology - 98 ; Climate and Air Quality - 78 ; Plants, Fish, and Wildlife - 277 ; Ecology - 135 ; and Oil and Gas - 70 . The format of each chapter is not always the same, but considera- tion is given to data deficiencies and research needs . This report may serve as a general reference work and aid in the synthesis of more specialized sub- ject material . This project was conducted under Contract FWS 14-16-0009-78-090 . Funding was provided by the Bureau of Land Management and 11 .5 . Fish and Wildlife Service . This study is designed to be used in planning for Outer Continental Shelf oil and gas development and for coastal zone management needs .
