Are you a Long Islander who counts down the days until summer? Is the beach your second home, or just a fun place to visit some weekends? Whatever the case, Long Island is your home. CSLI is an all volunteer organization and we could use your help to continue our efforts in preserving our local beaches and ecology. Join us in our mission to keep our Island home to some of the most beautiful and top-rated beaches in the United States, restoring populations of vital marine life, and educating the public.
