Introduction
Closes are meadows bounded by trees, in this case tamarisk, generally surrounded by irrigation channels. These very low-lying fields, close to the marshes and easily flooded, are not very productive for agriculture and were used as pasture for cows and horses.
They are the ideal habitat for amphibians such as: the Mediterranean painted frog, which is ideally adapted to the water system of the closes; the common tree frog, preferably in places with high grassy layers; the marbled newt, in closes with water present almost permanently.
Mammals that live there include moles, which live in the closes and shelter in the boundaries when they flood, and the field mouse, virtually the only murid to live in the boundaries of the closes.
