CORS ERDDREINIOG SSSI (and SAC and Ramsar site)

A large wetland, mostly National Nature Reserve, and the jewel in the crown of the Anglesey fens, marred only by the electricity pylons that stride through the centre of it!. The site boasts large areas of calcareous fen with great fen sedge, black bog rush, bog myrtle, southern damselfly, wintering hen harriers, marsh gentian .....etc. Access is obtainable from Capel Coch, to the west of the site, and there are new boardwalks being provided. However, the site is large, there are deep ditches and grazing livestock, so care is needed.
