Site description A complex of wetlands along the south-east coast of Sicily, around the town of Catania, and including the following sites: Biviere di Lentini, a freshwater reservoir; Foce del Simeto, a river-mouth; Traversa di Ponte Barca, a stretch of the Simeto river. There are large reedbeds at Biviere di Lentini. The main land-uses are water-resource management at Biviere di Lentini (for domestic water-supply), and nature conservation at Foce del Simeto. The surrounding areas are largely agricultural.

Key Biodiversity A very important site for waterbirds while breeding (especially Aythya nyroca and herons), migrating (e.g. Plegadis falcinellus, Platalea leucorodia) and wintering. The site holds more than 20,000 waterbirds on a regular basis, with Larus ridibundus especially common in winter.
