Cors Fochno is a raised peat mire located near to 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 (United Nations Educational, Scientific and Cultural Organization) biosphere reserve in 1976, and is the only such reserve in Wales.[1]

A significant portion of the 652 acres (264 ha) 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.[2]
