Chesapeake Bay's oyster population was once so vast that their reefs were navigation hazards for ships. Overharvesting reduced them to just 1% of historic levels. Now, the largest oyster reef restoration project in the world has reached a remarkable milestone: 10 billion oysters planted.
The Chesapeake Oyster Alliance, a coalition of over 100 organizations, has been rebuilding reefs using recycled shells and specially bred disease-resistant oysters. Each adult oyster filters up to 50 gallons of water per day, removing nitrogen and improving water clarity.
“Overharvesting reduced them to just 1% of historic levels.”
The restored reefs are already showing results: fish populations are rebounding, underwater grasses are returning, and water quality is measurably improving. "We're seeing the Bay come back to life," says project coordinator Dr. Stephanie Reynolds.
