This Site lies on the left bank of the Volturno delta in southern Italy and includes freshwater ponds surrounded by marshes and a saline lagoon separated by an artificial levee which connects the riparian strip with the mainland. It belongs to the last remaining portion of a formerly vast complex of swamps which was drained between the 17th and 18th centuries. Many bird species use the Site as a migration stopover or for wintering, including protected species such as the greater flamingo (Phoenicopterus roseus), the knot (Calidris canutus) and the near-threatened ferruginous duck (Aythya nyroca). River regulation and tourism are seen as a potential threat. There is a bird observation hut and a nature trail as well as educational activities for schoolchildren.
