S732 Cordilleran hedgehog-heaths
Description
Thorny cushion-forming scrub on deforested, recurrently burnt and heavily pastured siliceous slopes or plateaus originally occupied by T19A in inland areas of the submediterranean southwestern sector of the ecoregion. Also in ample ledges of exposed windy rocky outcrops, the presumable primary station of Echinospartum lusitanicum, the dominant, definitory species of the unit. Despite the too narrow geographical demarcation in its name, our communities fit comfortably in the accepted level IV EUNIS unit.
