Description

Description This site is designated for its botanical interest. The most noteworthy feature is the presence of a large population of the nationally rare annual rockrose Tuberaria Guttata growing in one of its nine known British localities. This is the only extant site on the main island of Anglesey, seven of the remainder being on Holy Island with one in the Lleyn Peninsula. Tuberaria Guttata is associated with thin acidic soils on rocky ridgelines or steep slopes. The more frequent associated species include sheep's fescue Festuca ovina, common bent Agrostis capillaris, squirrel-tail fescue Vulpia bromoides, early hair-grass Aira praecox, heather Calluna vulgaris, bell heather Erica Cinerea, western gorse Ulex gallii, spring squill Scilla verna and English stonecrop Sedum anglicum. Other notable plant species present include the nationally uncommon golden-samphire Inula Crithmoides on the sea cliffs, and the locally uncommon prickly sedge Carex Muricata subsp. Lamprocarpa and dodder Cuscuta epithymum.
