Oyster restoration projects target water quality in New York

Environmental restoration efforts are utilizing oyster populations to improve water quality and ecosystem health in New York waterways.

In New York Harbor, the Billion Oyster Project is repurposing restaurant waste by collecting 3.2 million pounds of discarded oyster shells. These shells are being used to build living reefs on Governor's Island. The project has already restored 19 acres of reef and grown 200 million live oysters. The organization aims to rebuild 100 acres of former reefs and reach a population of 1 billion oysters by 2035. These reefs act as natural filters for pollutants and help mitigate flooding by softening wave energy.

Similarly, in the Great South Bay, the nonprofit Save the Great South Bay is conducting a yearslong effort to restore the polluted waterway. Volunteers recently replanted approximately 30,000 baby oysters, known as spat, into sanctuary locations. Since 2013, the project has planted a total of 1.3 million oysters. These efforts aim to combat water quality deterioration caused by pollutants from private cesspools and large-scale developments.
