Résumé :
|
The Camargue, the delta of the Rhône River, is the second largest delta in the Mediterranean. Its hydrology is strongly modified by artificial flows of water during spring and summer. Water management enhances the natural gradients of salinity and hydromorphy, factors that determine the existence of diverse ecosystems (sand dunes, Salicornia steppes, fresh and saline wetlands, …). These ecosystems perform numerous ecological functions and provide important ecosystem services. Overall, the Rhône delta is one of the most important wetlands in the Mediterranean basin in terms of its area, hydrology, and biodiversity. Although the Camargue is known under numerous nature conservation statuses, it is increasingly difficult to counteract the mounting pressures from global change. A revised perspective on nature conservation is needed for the long-term protection of wetlands, its functions, and values.
