G2.121Niveau 5Chênaies à Quercus ilex mésoméditerranéennes
↑ Niveau supérieur
Description
Rich meso-Mediterranean Quercus ilex forests, penetrating locally, mostly in ravines, into the thermo-Mediterranean zone. They are often degraded to arborescent matorral (unit F5.11), and some of the types listed below no longer exist in the fully developed forest state relevant to category G2; they have nevertheless been included, both to provide appropriate codes for use in F5.11, and because restoration may be possible.
