The Po Delta wetlands have been protected by the institution of two regional parks in the regions in which it is situated: Veneto and Emilia-Romagna. The Po Delta Regional Park in Emilia-Romagna, the largest, consists of four parcels of land on the right bank of the Po and to the south. Created by law in 1988, it was managed by a consortium, the Consorzio per la gestione del Parco, to which Ferrara and Ravenna provinces belong as well as nine comuni: Comacchio, Argenta, Ostellato, Goro, Mesola, Codigoro, Ravenna, Alfonsine, and Cervia.
