The coastal marshes of the United States are viewed herein as an ecosystem, even though many of the articles listed in this bibliography are specific to only a narrow aspect of the ecosystem. The value of the marshes is shown in many ways: habitat for wildlife species, producer of nutrients, nursery areas, and protected rearing areas for juveniles. The report consists of an intoduction and a bibliography containing five major sections: Marshes and Marsh Vegetation; Primary Productivity of Marsh Plants; Detritus in the Food Chain; Marsh Estuaries as Fish Havens; and Marshes as Habitat and Feeding Grounds for Wildlife. Each of the major sections is divided into subsections that fall into a logical pattern so that a reader may work his way progressively through the materials, seeing a story unfold.
