U32 Temperate high-mountain siliceous inland cliff
Siliceous cliffs and rock faces of acidic, mostly Palaeozoic, rocks in the high mountains of the nemoral zone. Slow weathering of these resistant rocks creates few niches for colonisation and the vascular flora of the crevices and on ledges is rather species-poor but rich in epilithic lichens.
