Available in PDF, EPUB and Kindle. Book excerpt: 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).

Available in PDF, EPUB and Kindle. Book excerpt: Upland habitat development using dredged material as a substrate was shown by the Dredged Material Research Program (DMRP) to be a feasible alternative to standard dredged material disposal operations. This report synthesizes pertinent literature and research at three major DMRP upland field sites: Miller Sands in the Columbia River, Oregon; Bolivar Peninsula in Galveston Bay, Texas; and Nott Island in the Connecticut River, Connecticut. Guidelines for developing existing or potential dredged material disposal sites into upland habitat are presented: (a) planning and designing the project in relation to the proposed site and project goals; (b) construction of the site including dredging and disposal operations, substrate modifications, and vegetation establishment; (c) maintenance and management of the site as a habitat; (d) costs of proposed and sample projects; and (e) potential problems that may be encountered.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 1978 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: Miller Sands, an island complex in the lower Columbia River, is largely derived from dredged material. Three distinct habitat types are recognized: a large vegetated upland island formed prior to 1940; an elongate barren sand spit formed primarily since 1970; and a cove protected by the island and the spit. In July of 1975, a pilot study was conducted under contract with the Waterways Experiment Station (WES), in which a total of ten plots were planted with transplants of five species of vascular plants endemic to the area. The primary purpose of this pilot study was to identify the best plant materials for use in larger scale experiments in 1976. Five experimental sites were selected in 1976 by WES to study the propagation of selected plant species: upland plantings consisting of monotypic plots and meadows, sand spit plantings, and intertidal plantings consisting of monotypic plots and a species mixture. The upland experimental sites were located on the older, vegetated island. The upland plantings consisted of various experimental treatments with a total of nine seeded grass and legume species. As a result of efforts at the Miller Sands site, much information has been generated regarding the feasibility of planting various intertidal and upland species. Such information should be useful in future endeavors to establish marsh habitat, and should be valuable in reducing costs of similar propagation efforts.

Newling and published by . This book was released on 1985 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 excerpt: A study of existing conditions of terrestrial ecology at Miller Sands Island showed that the vegetation on the main island consists of open grassland areas and wooded areas. That the grassland contains scattered trees and shrubs indicates that succession from open grassland to wooded areas is occurring on the island. Sixty-five different species of birds were observed. Changes in numbers and species are attributed to the emigration of waterfowl and shorebirds. During spring and fall migrations the island and environs provide resting and habitat. While birds have apparently colonized the island, mammals, amphibians, and reptiles have not. No amphibians or reptiles were observed during a search of suitable habitats. Since only a few small mammals were captured, numbers on the island are believed to be limited, with the exception of nutria. Nutria, which have relatively high water mobility, were observed during each sampling period and maintain trails in all habitat on the island. (Author).
