Coastal Steward Long Island (CSLI) is dedicated to restoring and preserving Long Island’s coastline through education, raising public awareness, and community action. CSLI programs educate our youth and local community groups in coastal environmental awareness through beach cleanups, shellfish population restoration, and citizen science. By engaging with our local youth and communities, we foster a caring connection between Long Island residents and their shoreline, and create future generations of coastal stewards.
