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.
