Deposit soil/sediment to form physical structure of brackish/saline swamps
Overall effectiveness category No evidence found (no assessment)
Number of studies: 0
Background information and definitions
This action involves large-scale deposition of soil or sediment to form the physical structure of a swamp. This can be a cost-effective alternative to depositing sediment in upland areas or in the ocean (LaSalle et al. 1991). Soil or sediment could be placed directly where a swamp is desired, or placed nearby then carried to the desired site by water flows (Foster et al. 2013). Summarized studies could vary in the degree of landscaping of the newly deposited sediment.
Related actions: Deposit soil/sediment and introduce vegetation; Add sediment in relatively small amounts; Add upland topsoil; Transplant or replace wetland soil in order to introduce swamp vegetation.
