Mediterranean temporary ponds and livestock water ponds are natural or artificial ecosystems, throughout the work area. Each farm has several.

Life around them is kept in the pastures. More than a dozen species of amphibians can live in these ponds, whether managed properly, impoverished communities living if subjected to overfishing and eutrophication. Macrophytes lining the ponds and the black stork always use those that they can wade through. Much of the explosion of biodiversity of the meadow revolves around this medium that holds water during dry summers.
