Cors Fochno


Cors Fochno is a raised peat bog near the village of Borth, in the county of Ceredigion, Wales. Lying on the south side of the Dyfi estuary, it forms a component part of the Dyfi National Nature Reserve. It was designated a UNESCO biosphere reserve in 1976, and is the only such reserve in Wales. A boardwalk leading from the northern edge of the bog skirts the edges of the bog and surrounding woodland.
A significant portion of the former peatland complex was taken for agriculture; the surviving core area supports the largest expanse of primary near-natural raised bog in an estuarine context within the United Kingdom.
A large peatland area south of Lago General Vintter in Chubut, Argentina, bears the name Cors Fochno, adopted in reference to the original peat bog in Ceredigion.
