The Cesine oasis measures 620 hectares (1532 acres) and is all that remains of the marshes that once stretched from the coast to a line of dunes. The oasis has two ponds, the Pantano and the Grande Salapi, which are fed by rainwater and are no deeper than two meters (six-and-a-half feet). The vegetation is typical Mediterranean maquis, in particular, kermes oak. The further inland you go, however, the combinations of plants and trees alter as the land changes. Birds are the most common form of wildlife and in winter coots, pintail ducks, sheldrakes and pochards can be seen.
