Submerged aquatic vegetation (SAV) are rooted, vascular plants that grow completely underwater, such as eelgrass. SAVs are an important food source for waterfowl, provide habitat and nursery areas for finfish and shellfish, absorb nutrients and remove suspended sediment from the water. Eelgrass is present year round, while brackish and fresh water SAVs are most prevalent during the growing season from June through August. Docks and boats can damage SAVs by blocking sunlight which is critical for growing. Eelgrass beds play an important role in the Long Island Sound ecosystem.
