U27 Temperate, lowland to montane base-rich scree
Screes of mostly coarse, unstabilized material derived from calcareous and dolomitic bedrocks in the lowlands, foothills and sub-montane zone of temperate Europe. Vegetation can be completely lacking, but rock surfaces can have bryophyte and lichen communities and, where crevices accumulate soil, the vascular contingent can be diverse and lush. Natural succession following stabilization of screes allows encroachment of shrubs and trees, vegetation not included here.
