Revitalizing The Great South Bay And The South Shore

It’s our bay, our heritage — and our legacy. We grew up clamming it, sailing it, swimming in it. Now our bay is sick, and we must heal it, now, today, and for the future!

We are a local 501(c)3 Non-Profit that advocates for and implements real solutions that will help restore the bay, and with that strengthen our South Shore communities.

Discover How You Can Help Save The Bay

Start In Your Own Backyard!

Go native! The suburban lawn is heavily reliant on fertilizers, pesticides, and huge amounts of water. It’s polluting, expensive, lifeless and tired. Choose a Bay Friendly Yard instead. Native plantings belong here. They are cheaper to maintain. They are beautiful — Nature untouched. And they filter and clean the groundwater before it hits a creek or the bay.

It all starts with you! Just register your email address below to receive our free Bay-Friendly Yard E-Book! You’ll get the basic info you need to help the bay right at home!

Inside the eBook:

  • Step-by-step instructions for assessing your yard
  • Lists of native species that would thrive in that yard
  • Tips on how these plantings should be arranged

Become a Creek Defender

By our count, there are 50 creeks flowing through 16 South Shore communities into The Great South Bay. The Creek Defender Program has a Defender in nearly every community — Massapequa, Copiague, Amityville, Lindenhurst, Babylon, Bay Shore, West Islip, Islip, East Islip, Great River/Oakdale, Sayville, Bayport, Bluepoint, Patchogue, Bellport and Brookhaven.

Each Defender coordinates with local schools, civic associations, and local businesses, organizing local cleanups and native plantings or “Swamp Forests” along the creeks.  Plans for Creek Defender Day 2020 are in the works.

Remember: the bay is a symptom; it’s the mainland that’s sick. A lot of the pollution flowing into the bay is from our creeks — runoff from roads and lawns, pesticides and fertilizers, trash, and of course nitrogen from antiquated cesspools and septic tanks. By restoring native habitats, rebuilding green corridors, we can improve water quality in the creeks and therefore the bay.  Click on the link below, tell us where you are from, and we will connect you with your Creek Defender!
