S6-2 - Garrigues acidiphiles occidentales

Western acidophilous garrigue

Classification des habitats EUNIS 2022

Descriptif de l'habitat

Sub-shrub vegetation dominated by nanophanerophytes on thin, acidic soils, developed on hard silicate bedrock or soft sand, through the western thermo- to lower supramediterranean 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 or abandonment of farm fields and is much affected by grazing and fire.
