The Native Oyster Restoration Alliance (NORA) supports the protection and ecological restoration of Ostrea edulis, the native European oyster (also known as the flat oyster) and its habitat in areas of its current or historical distribution. The aim is to overcome existing barriers to the conservation, restoration and recovery of this ecologically important species. To this end, NORA has developed into a hub for knowledge exchange and collaboration.
