Parmotrema robustum

Range & Status

A large foliose species growing on mossy, north-facing serpentine rocks in Gew Graze valley north of Kynance Cove. A very rare species which is also known from S.W. Ireland, Cardiganshire and Merioneth. The species, in its heathy coastal site, is vulnerable to fire and the creation of a firebreak and the introduction of grazing around the single site would help to diminish this threat.
