The Camargue was classified as a Biosphere Reserve in 1977 by UNESCO. Between these folds still partly wooded, are divided lowlands occupied by lagoons lined with salt steppes, marshes and ponds. The agricultural lands are composed of wet meadows and grazers dedicated to the grazing of bulls and horses, old marshes converted into rice paddies of lagoons designed for the exploitation of salt and vegetable crops and viticulture on the dunes.
