A large coastal plain between the hills of Skikda and the forested massif of Chetaïbi near Cap de Fer, which includes the delta of the Wadi El Kébir. Among the characteristic dunes can be found a multitude of depressions and valleys forming lakes and garâas (marshes) from a few to several dozen hectares in area, on a plain that is described as a “bioclimatic crossroads” as it includes sub-Saharan and European as well as Mediterranean characteristics. There are some 234 plant species representing 145 taxa, with 50 species of birds and 27 species of dragonflies and damselflies. The Site is important for migratory birds, especially as a nesting place for Oxyura leucocephala and Aythya nyroca, and fish including European eel Anguilla anguilla. Human uses include agriculture (especially cultivation of tomatoes and melons) and grazing; potential threats include unmanaged agricultural expansion, and runoff and wastewater from upstream villages. Since World Wetlands Day of 2016, the Site has included a public education and awareness centre.
