Clegir Mawr is a Site of Special Scientific Interest (SSSI) in the community of Cylch-y-Garn in the north-west of the island of Anglesey, Wales. It is a stony coastal headland with an area just under 10 hectares (25 acres) and has been designated principally because of the occurrence of the spotted rock-rose (Tuberaria guttata) which is a nationally rare plant and also the county flower of Anglesey.
Site[edit]
The site includes two areas north of Church Bay (Porth Mawr) and includes coastal heath, coastal grassland, sea cliffs and scrub habitats with a total area of 9.6 hectares (24 acres).[1][2] Much of the area around the site is owned by the National Trust and includes the Isle of Anglesey Coastal Path.[3][4]
Importance[edit]
The principal feature is the spotted rock-rose which favours thin acidic soils on rocky ridgelines or steep slopes. The spotted rock-rose is only known to exist in nine British locations. One location is on the Lleyn Peninsula and the remaining seven are on Holy Island, Anglesey.[5] The flower blooms from June to August and the blooms last only a day.[6] The flower is the county flower of Anglesey.[7]
The conditions for the spotted rock-rose are also support a number of other species including sheep's fescue (Festuca ovina), common bent (Agrostis capillaris), squirreltail 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).[5]
The uncommon golden-samphire (Inula crithmoides) is found on the sea cliffs, and the prickly sedge (Carex muricata) and dodder (Cuscuta epithymum) are also found on the site.[5]
