U34 Mediterranean siliceous inland cliff
Siliceous rock walls and cliffs from the lowlands to high mountains in the Mediterranean, formed chiefly of igneous or metamorphic origin which offer a diversity of niches for colonisation depending on the rock texture, schistosity, moisture content and chemistry. Typically they have cushion or rosulate vascular plants, some of them succulent, ferns and dwarf shrubs, with bryophytes, lichens, epi and endolithic micro-organisms.
