The Native Oyster Restoration Alliance (NORA)

The Native Oyster Restoration Alliance (NORA) is a European network whose aim is to enhance and restore the native European flat oyster (Ostrea edulis). Network members represent govt. employees, scientists NGOs, oyster growers, and other private groups. NORA was an outgrowth of a workshop on oyster restoration held in Berlin, Germany on Nov. 2017. That meeting was organized by the German Federal Agency for Nature Conservation (or BfN), and the Alfred-Wegener-Institute Helmholtz-Centre for Polar and Marine Research (or AWI) and was attended by 65 experts from 10 European countries and the U.S.
