Classification des habitats EUNIS 2022

Descriptif de l'habitat

Sub-shrub vegetation dominated by nanophanerophytes and chamaephytes on thin, base-rich soils through the western thermo- to mesomediterranean belts. Its species composition is very diverse in response to differences in local climate and soils. On rocky slopes, it can be permanent vegetation but is often derived from forest clearance and is much affected by grazing and fire.
