Book Description
The feasibility of developing additional wildlife and fish habitat at Jetty Island, Everett, Washington, using dredged material was explored. Existing literature were reviewed and field surveys undertaken to define environmental conditions at the site and to determine constraints of developing habitat adjacent to the island. Terrestrial plant communities and intertidal habitats were characterized. Based on the analysis of field data and literature, the most suitable location for habitat development was found to be on unvegetated mudflats adjacent to the western shore of Jetty Island. Four alternative concepts (enclosed pond, spit/open lagoon, enclosed lagoon, islands) consisting of seven designs were evaluated. Of those seven designs, four were considered feasible based on such constraints as quantity of material available, tidal and current conditions, stability of substrate, location of dredging sites, and monetary considerations. The habitat types found to be most suitable for development were salt marsh and beach grassland. The preferred project design is an enclosed lagoon with tidal access via a channel from the protected eastern shore of the island. Approximately 24 acres of marsh community, 6 acres of beach grassland, and 5 acres of sand beach would be created. The project would primarily benefit juvenile fish (salmon, smelt, shiner perch, and Pacific Herring), waterfowl, shorebirds, and wading birds.

An Introduction to Habitat Development on Dredged Material

Publisher:
ISBN:
Category : Artificial islands
Languages : en
Pages : 50
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.
