Lakenheath Fen RSPB reserve is located on the Norfolk/Suffolk border in England, between Lakenheath and Hockwold cum Wilton adjacent to Lakenheath railway station.
Until 1995, when purchased by the RSPB, the land now forming the reserve was heavily farmed arable land. Since then, the 740-acre site has been turned back into the reed beds and grazing marshes that would once have been common in the area. To achieve this, over 2 km of ditches were re-shaped with shallow sloping sides so as to encourage reed growth and to provide feeding areas, particularly suited to great bitterns. A number of sluices were installed to enable water levels to be controlled. In addition to the existing ditches, over 4 km of water channels were dug to re-circulate water around the site.
