Book Description
During the Dredged Material Research Program, six wetland and three upland habitat development projects were established at seven sites to demonstrate the feasibility of creating productive habitat on dredged material deposits. Wetland sites were Windmall Point in the James River, Virginia; Buttermilk Sound near the Altamaha River, Georgia; Drake Wilson Island in Apalachicola Bay, Florida; Bolivar Peninsula in Galveston Bay, Texas; Salt Pond Number 3 in South San Francisco Bay, California; and Miller Sands Island in the Columbia River, Oregon. Sites were also located in upland areas at Nott Island in the Connecticut River, Connecticut; Bolivar Peninsula; and Miller Sands. These sites have continued to be monitored since their construction (1975-77) until the present time. In addition, three natural marsh upland reference sites have been selected for comparison to the man-made sites. Data and research results are presented in this report. Results over an 8-year period indicate that all of the sites have developed and stabilized, and that they have all been highly successful. Despite a complete lack of management since construction, the sites maintain plant communities generally comparable to or more productive than those on the reference areas. Wildlife use exceeds that occurring on reference areas, and the sites are compatible with and contributing to the ecosystems of which they are a part. (Author).

Book Description
Eleven habitat development field sites built by the US Army Corps of Engineers (CE) on dredged material were monitored from 1974-1987 in response to questions regarding their ecological contribution and longevity in comparison to natural habitats. Seven sites (Nott Island, Conn; Windmill Point, Va; Buttermilk Sound, Ga; Apalachicola Bay Fla; Bolivar Peninsula, Tex; Salt Pond no. 3 Calif; and Miller Sands Island, Ore) were built during the CE Dredged Material Research Program. Four sites (Gaillard Island, Ala; Lake of the Woods, Minn; Pointe Mouillee, Mich; and Southwest Pass, La) were added to the long-term monitoring effort. Each site differed according to the type of habitat developed, location, dredged material substrate, structural development, water and energy regime, land-use potential, regional habitat needs, salinity, or other features representative of those encountered most often by field personnel in CE District offices where dredging occurs. Nine are intertidal, 5 are in fresh water, 3 in brackish water, and 3 in salt water. Two are large-scale, ongoing confined disposal facilities (CDF).

Book Description
Contaminated sediment was dredged from Black Rock Harbor, Connecticut, in October 1983 and placed in aquatic, upland, and wetland environments as part of the Field Verification Program (FVP), conducted during the period 1981-1986. Laboratory tests were conducted on the sediment prior to dredging to evaluate potential contaminant mobility under each of the disposal alternatives. Prior to dredging for upland disposal and wetland creation at the FVP field site, upland tests (i.e., plant and earthworm bioassays) and wetland tests (i.e., plant, sandworm, snail, and mussel bioassays) were conducted. Laboratory test results were subsequently field verified at the field test site at Tongue Point, Bridgeport, CT. The results of the upland disposal and wetland creation portions of the FVP, and the changes occurring since completion of the FVP for each disposal environment, are summarized herein. The emphasis of this report is on the contaminant mobility of heavy metals. This interim report includes data collected through 1989. Contaminant mobility and the progressive development of the upland and wetland ecosystems at this site will be evaluated until September 1995.

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.
