CLIFF FACE

Cliffs have inaccessible vertical faces which are safe for birds to make their nests, seabirds such as herring gulls and shags, also ravens, peregrine falcons and kestrels, and rock doves and rock pippets. Plants include rock and golden samphire, scurvy grass and thrift which grow in crevices.
