Importance

Coastal habitats provide a unique and highly productive ecosystem that supports an array of living resources. However, due to development activities, the abundance and diversity of coastal habitats in Long Island Sound has declined. As a result, the Long Island Sound Study’s Habitat Restoration Initiative identified 12 important coastal habitats to restore. These coastal habitats include tidal wetlands, eelgrass, estuarine embayments, cliffs and bluffs, coastal grasslands, coastal forests, freshwater wetlands, beaches and dunes, and intertidal zones.

Trends

As of 2015, the Long Island Sound Study is 87.3% of its way toward meeting its 2020 goal of restoring a total of 2,000 coastal habitat acres.
