34.3263 - Causses Mesobromion

Classification des habitats du Paléarctique (2001)

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 Ophrys aymonini find their optimal habitat in these communities ("Orchideto-Brometum").
