Coastal Steward Long Island
Dedicated to revitalizing Long Island’s marine ecosystems—one oyster at a time.
2026 OYSTER RELEASE
For years, Coastal Steward Long Island has fostered a deep connection between residents and our shorelines through
three core program pillars:
Education
Preservation
Restoration
To maximize our ecological impact with current volunteer and funding resources, we have paused two of our programs to focus 100% of our operations on shellfish restoration.
Explore our years of dedicated work—and see how you can help bring paused programs back to life.
How can oysters help improve the health of the Long Island Sound?
Water Quality: Oysters filter particulates and nutrients from water which improves water quality and clarity.
Habitat Creation: Shellfish reefs provide structure and habitat for marine species
Shoreline Protection: Shellfish reefs are a natural buffer by reducing wave energy and preventing erosion.
Increased Biodiversity: A healthy ecosystem boosts the entire marine food web.
How can YOU make a difference?
We meet at Cedar Beach in Mount Sinai roughly every two weeks from May through to October to clean our shellfish bags in cages, maintain our shed, and give tours of the shellfish hatchery.
Please check our Volunteer Calendar and come help us restore our local shellfish population. We look forward to seeing you there!
