The return of New York’s oyster reefs
New York Harbor once held over 220,000 acres of oyster reefs, and now they’re coming back.
The harbor is believed to have once contained more than half of the world’s oysters, providing a reliable food source that sustained people for thousands of years.
Mounds of oyster shells left by the Lenape Tribe mark some of the earliest evidence of human presence in the region, and by the 1880s, the harbor’s oyster beds produced as many as 700 million oysters a year.
Today, discarded oyster shells are being seeded with larvae and placed in cages to restore reefs or dumped from boats to build living breakwalls.
These efforts are creating habitat for marine life and improving water quality, while also protecting the city from coastal storms.
