Bolshayne Fen : ウィキペディア英語版 | Bolshayne Fen Bolshayne Fen () is a wetland in southeast Devon, England. It has an area of 1.62 hectares. The site was designated as a Site of Special Scientific Interest on 25 September 1992. ==Site Description== This site contains an unusually large and intact valley fen, supporting rich marsh vegetation of a type known only at two other sites in Devon and which is now nationally scarce. The fen occupies a single field at an altitude of 40 m, through which runs a small stream called Nanny's Water, which is a tributary of the River Coly. Its soils consist of deep waterlogged peaty loam above Triassic mudstones, with Cretaceous Greensand on the valley sides above. During winter it periodically floods.
