Cors Bodeilio

Cors Bodeilio is a nationally important nature reserve due to its unique mire, which lies in a shallow limestone valley between Llangefni and Pentraeth, on the Isle of Anglesey. Water from the surrounding Carboniferous limestone rocks feed the mire, and this in turn has encouraged the development of a range of different wetland fen species, which prosper over the bed of fen peat. Together with other Anglesey fens, this type of threatened wetland is very rare – in fact, because of the incredible range of wildlife it plays host to, the reserve has a number of designations at hand to protect it.

The reserve is at once recognized as:
· A wetland of international importance (Anglesey and Llyn Fens RAMSAR)
· A Site of Special Scientific Interest (Cors Bodeilio SSSI)
· A Special Area of Conservation (Corsydd Môn/Anglesey Fens SAC)
