WHAT ARE TIDAL WETLANDS?

Tidal wetlands are the transitional zone between the land and submerged systems. These 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. About 75 percent of coastal habitat acres restored in Long Island Sound are made up of tidal wetlands.

WHAT OTHER COASTAL HABITATS ARE BEING TRACKED?

Long Island Sound Study’s Habitat Restoration Initiative has identified 12 key habitats to restore. Besides tidal wetlands, habitats that have been restored include eelgrass, estuarine embayments, coastal grasslands,coastal forests, freshwater wetlands, beaches and dunes, and fish passage on streams. The fish passage data are included as a separate indicator because units are measured in miles, not acres.

WHAT DOES THIS INDICATE?

This indicator tracks efforts by the states and the Long Island Sound Study to restore ecosystem function in coastal habitats, including tidal wetlands.

STATUS

The Long Island Sound Study Habitat Restoration Initiative has a goal to restore 2000 acres of coastal habitats by 2020. As of 2015, the initiative is 87.3% of its way toward meeting the goal.
