S23y Juniperus nana scrub on acid soils
Description
Silicicolous analogue of S23x. The local abundance of Cytisus oromediterraneus and other Oroiberian endemics (recalling the EUNIS unit S333) contrasts with the boreo-alpine floristic background of S223, with which this community alternates topographically, giving further support to the creation of a new unit as explained under S23x.
