Boreal and arctic base-rich inland cliff

Description (English)

Vegetated cliffs on base-rich (not ultramafic or salt-sprayed) bedrocks across the boreal region, including Scotland, and maybe Iceland. They are often rich in ferns, crustose lichens and, in sunless, damp situations, particularly in more oceanic areas, bryophytes.
