Limestone Rock Outcrops, Cliffs & Scree
Exposed limestone cliffs support species such as wild thyme and blue moor grass in association with specialist cliff species such as common whitlowgrass, hairy rock-cress, thale cress, hoary whitlowgrass and wall whitlowgrass, biting stonecrop and the rare winter hutchinsia.
More shaded and sheltered cliffs support ferns such as wall-rue, maidenhair spleenwort, green spleenwort, brittle bladder-fern and lesser clubmoss. Wetter flushed cliffs support marsh hawk's-beard, Pyrenean scurvygrass, mossy saxifrage and stone bramble. In very sheltered, stable areas more robust flowering plants can occur such as, rock-rose, small scabious, bloody crane's-bill and marjoram. Limestone screes also support a rich diversity of lime-loving species such as maidenhair spleenwort, wall-rue, herb Robert and more specialist species such as the limestone polypody fern.
