Book Description
Habitat development using dredged material offers an alternative dredged material disposal method that is often feasible from biological, engineering, and economic standpoints. Careful use of this alternative could significantly increase the extent of wetland and wildlife resources in many parts of the United States. Four general habitats are suitable for establishment on dredged material: marsh, upland, island, and aquatic. Marsh establishment has received more attention than any other habitat development alternative, and techniques have been developed to enable careful planning, design, and propagation of these habitats. Terrestrial habitat development is primarily the application of established wildlife management and soil reclamation procedures at a particular disposal area. The feasibility of both the marsh and terrestrial habitat development alternatives has been documented in numerous field and laboratory studies. Island habitat development uses a standard technique to dispose of dredged material and create exceptionally important wildlife habitat. This is often a viable alternative that can be greatly improved by management techniques. The development of aquatic habitats, such as seagrass meadows and oyster flats, on dredged material appears to offer significant potential for the creation of highly productive biological communities and at the same time provide for large disposal quantities; however, aquatic habitat development is largely untested in the field.

Book Description
Regional habitat development and preservation priorities should be established by identifying target populations, groups, or communities and their support populations in an ecosystem context. Properly planned dredged material habitats can be both visually and functionally compatible with preexisting natural habitats. The character of any upland, island, wetland, or aquatic habitat is determined by both physical (geomorphological, hydrological, climatological) and ecological (succession, competition, predation) principles. Properly planned disposal operations serve to modify physical conditions and thereby influence (with some predictability) biological responses. Chemically enriched (polluted) dredged material can be used to develop productive fish and wildlife habitats if available information about mechanisms affecting chemical solubilization and biological availability is incorporated into project design. Consequences of habitat displacement are not easily avoided because of limited understanding about the relative value of various sizes and configurations of specific habitat types. An awarenes of existing information describing the value of habitat types to management target resources together with studies designed to clarify specific target population-habitat interactions provides the only insurance against cumulative reduction in fish and wildlife resources. Blanket habitat development policies used in lieu of consideration of the unique qualities of each ecosystem should be avoided. (Author).

Book Description
Marsh habitat development using dredged material as a subsrats was shown by the Dredged Material Research Program (DMRP) to often be a feasible alternative to traditional dredged material disposal operations. This report synthesizes pertinent literature and research of the DMRP including six major marsh development field sites: Windmill Point in the James River, Virginia; Buttermilk Sound on the coast of Georgia; Bolivar Peninsula in Galveston Bay, Texas; Miller Sands, Columbia River, Oregon; Drake Wilson Island in Apalachicola Bay, Florida; and Salt Pond No.3, South San Francisco Bay, California. Guidelines for developing marsh habitat are presented: a) planning the project in relation to the proposed site and project goals; b) engineering construction of the site including dredging operations; c) propagation, maintenance, and monitoring of the site as habitat, including potential problems that may be encountered; and d) costs. Emphasis is placed on two major areas: engineering and plant propagation. Engineering aspects and design of potential sites are discussed and include protective and retention structures, substrate and foundation characteristics, dredging operations, and elevation and drainage requirements. Phases of plant propagation are detailled in the text and tables: selecting plant species for the site, collecting and storing plant materials, selecting a propagule type, planting the site, maintaining and monitoring the site, pilot studies, costing the work, and allowing natural colonization. A synopsis of 28 plant species discussing their characteristics, value, and potential use on dredged material in included as an appendix. Tables of 115 selected plant species showing best propagules; occurrence by region and whether now occurring on dredged material; growth requirements; propagule handling methods; soil, salinity, and inundation tolerances; and other pertinent information are given.
