34.3263 - Niveau 6 : Mesobromion des Causses

Description

Formations of the Causses; in the southern Causses they are mostly limited to the valleys where they occur at the base of slopes and, more rarely, on alluvial terraces; they also occupy the plateaux of the Causse de Sauveterre; the endemics Ophrys aveyronensis and O. aymonini find their optimal habitat in these communities ("Orchideto-Brometum").
