Restore Our Harbor

Volunteers are Helping

Restoration is a community effort! Join us for Fridays on Governors Island to build and install oyster reefs, monitor water quality, learn about NY Harbor, and much more. All ages welcome! Learn more about how you can bring BOP to your community with local restoration, outreach, fundraising, and special events.

BOP Schools & Community Science

BOP middle schools are satellite campuses for oyster restoration. They adopt and install Oyster Restoration Stations, then take monthly trips to their site to measure oyster growth, water quality, and biodiversity of the harbor. Their data is shared with schools and scientists around the region to help improve our local knowledge of restoration.

Restaurants are Helping

Restaurants play a crucial role by donating spent shells to BOP's aquaculture program. NYC restaurants currently throw away about 500,000 shells per week, most of which end up in distant landfills. BOP collects this valuable resource to create growing medium for oysters and building blocks of new reefs.


our story



acres of oyster reefs

When Henry Hudson entered New York Harbor in 1609, he had to navigate the Half Moon around 220,000 acres of oyster reefs, which had sustained the local Lenape people for generations. The pristine estuary, with oysters at the base, hosted thousands of associated species and was one the most biologically productive, diverse, and dynamic environments on the planet.


The Harbor was nearly lifeless and toxic for over

50 years


Clean Water Act

By 1906, New Yorkers had eaten every last oyster, reefs were dredged up or covered in silt, and the water quality was too poor for regeneration of oysters or anything else for that matter (not even the hardy boring worm which eats into wooden pilings and ship bottoms). The Harbor was toxic and nearly lifeless for more than 50 years until the passage of the Clean Water Act in which prohibited dumping of waste and raw sewage into the Harbor.


At the turn of the 21st century, thanks to environmental laws like the Clean Water Act, water quality improved so that conditions were finally ripe for large-scale restoration and the Billion Oyster Project was launched.


1 Billion

Live Oysters

100 acres

of oyster reefs

By 2035, one billion live oysters will be distributed around 100 acres of reefs, making the Harbor once again the most productive waterbody in the North Atlantic and reclaiming its title as the oyster capital of the world.
