Long Island Sound Study: Priority Habitats
Tidal wetlands are the transitional zone between the land and submerged systems. There areas are dominated by rooted plants that are flooded by the tide. Healthy wetlands help trap sediments, store flood water, and reduce wave energy during storms. Two-thirds of all marine species depend on tidal wetlands for a portion of their life cycle.

During the 1950s, portions of the Hammonasset wetlands were used as disposal areas for sediment that was dredged from nearby Clinton Harbor. Low earthen dikes were constructed around certain wetland areas and the sand was hydraulically pumped to the Park. At this particular location, certain areas of the wetland had been converted to upland supporting grasses, and red cedar, while other portions sill remain or became degraded salt marsh. As part of the restoration of the five-acre site, one to three feed of sandy dredged sediment was removed. Four ponds were constructed and a network of meandering creeks was installed to provide adequate tidal flushing. After restoration, salt marsh plants such as spartina alterniflora colonized the bare peat.
