our mission
one billion
oysters
Why? One billion is the population-level goal that moves the Harbor toward lasting recovery.
Oysters are a foundational species in New York Harbor. Their reefs create habitat for marine life, strengthen shorelines, and rebuild the ecological systems that once made this one of the most productive estuaries on Earth.

But small reefs aren't enough — to survive, oyster populations have to function as connected systems that reproduce and sustain themselves.
one million
students
Why? One million students builds a generation of New Yorkers ready to carry the work forward.
The future of New York Harbor depends on whether the next generation feels connected enough to protect it. When students learn straight from the Harbor — testing water, raising oysters, getting their hands dirty — they come to see that nature is part of New York, right in their backyard.

But restoring a harbor this size takes cultural change at the scale of the city around it.

Creating a connected network of oyster reefs

We're conducting a comprehensive study to map the Harbor's potential for large-scale restoration. Across the New York Harbor, we're identifying optimal sites to create self-sustaining reefs, measure ecological impact, and building the blueprint for our next decade of work.
