A peatland site in south Yorkshire noted as primeval country and listed alongside its near neighbour Thorne Moor. Proposed to the Society as a breeding place for scarce creatures, a locality for scarce plants and of geological significance. Around two thirds of the site has been destroyed by peat extraction for horticultural use. The remaining areas of habitat are now protected within the Humberhead Peatlands National Nature Reserve which also covers nearby Thorne Moor.
