Stone by stone, construction crews are creating the base for a large new oyster reef in the Hooper Strait Oyster Sanctuary in Chesapeake Bay. The NOAA-funded project is designed to establish more than 70 acres of habitat, building on years of local restoration work. Oyster reefs can help filter coastal waters and provide shelter for other species, making them valuable features of a healthy estuary. Construction is underway, and the longer-term ecological gains will depend on how the reef develops. This GoodWorld summary was independently written from NOAA Fisheries’ October 19 report.
