The Mediterranean temporary ponds and livestock ponds form aquatic ecosystems, natural or artificial, throughout the working area. Each farm has several of them. Around them, life is maintained in the pastures. More than a dozen species of amphibians can live in these ponds, if they are properly managed, with communities of living beings being impoverished if they are subjected to over-exploitation and eutrophication. Macrophytes cover the ponds and the black stork uses them whenever it can wade through them. A large part of the biodiversity burst of the pastureland revolves around this environment which maintains water during the dry summers.
