A wild peaty fen in Cambridgeshire owned by the National Trust and selected by the SPNR as an example of fenland habitat (of which only a few vestiges remained at the turn of the twentieth century). The fen was requisitioned for agricultural use during World War War and, as a result, the fenland habitats were largely destroyed. After the War the land was returned to the National Trust and, although some of the fenland habitats have been lost, the area is now part of the National Trust's large-scale fenland restoration programme at Wicken Fen.
