The Devès vegetation, on its slope oriented to the south west very exposed to the sun, is particularly adapted to the hot and dry conditions: it's the scrubland. Several varieties of juniper (G. commun, G. cade, G. of Phenicia) have colonized this stony and filtering soil, where oaks and pines can not plant their roots. Their tiny leaves (thorns) and their small size are all strategies developed to limit their needs (and losses) in water.
