Site description The site is a narrow coastal lagoon located between the towns of Korba and Menzel Temime, on the eastern coast of the Cap Bon peninsula. It is 12 km long, but never exceeds 400 m in width. It is the largest surviving lagoon of a chain which used to extend all along the eastern shore of the Cap Bon peninsula, several of which have dried up because of agricultural use of groundwater. Water-levels are quite deep in winter, because of winter rainfall, but most dry out in summer; the Korba lagoons remain wet even in summer because they receive treated waste-water from the town and the organic outflow from canning factories. The seaward shoreline supports a dune vegetation comprising Ammophila arenaria, Erygium maritimum and Euphorbia paralias. The edges of the lagoon itself support a halophytic vegetation, including Arthrophytum and Salicornia species.
Key Biodiversity See Box for key species. Given the site’s situation directly on the path of birds migrating between Africa and Europe, it is a key stop-over site for migrants in spring and autumn (when it is one of the few wetland sites which regularly hold water). A wide variety of waterbirds occur, especially herons, waders, gulls and terns, including Ardea cinerea, Egretta garzetta, Phoenicopterus ruber, Tadorna tadorna, Marmaronetta angustirostris (40–100 birds on passage), Anas platyrhynchos, A. clypeata, A. acuta, Calidris minuta, Himantopus himantopus (up to 250 pairs breed), Charadrius dubius, C. alexandrinus and Recurvirostra avosetta.
Non-bird biodiversity: None are known to BirdLife International.
