The steppe plains are home to a very high biological richness normally linked to the agricultural and livestock exploitation carried out in these places, which are in general decline, as is their biodiversity. The dry farming of cereals, interspersed with French lavender, brooms and wild olive trees, is interrupted by the willows of the riverbanks. An agrosystem where the symbiosis of human activity and wildlife makes it possible for important steppe bird populations to survive, such as black-bellied sandgrouse, pin-tailed sandgrouse, collared pratincole, little bustards, great bustards, Eurasian stone-curlew, hawks, Hen harriers and lesser kestrels.
