A floodplain fen in the River Ant valley, part of the Ant Broads and Marshes SSSI, billed in its SSSI designation as "one of the finest valley fens in Western Europe". The c.200Ha site includes areas of ancient alder carr, willow and birch scrub, small areas of Sphagnum bog as well as some 'upland' (up to 3m above sea level) meadows and woodlands. Benefiting from some historic recording by Robert Gurney at the start of the 20th century and latterly by the RSPB since the site was purchased in 2007, the species list is growing at pace. The floodplain is amongst the finest in the Broads thanks to a history of good management, good quality water (relative to most of our polluted waterways, at least), calcareous groundwater inputs and historic peat digging creating earlier succession peat than across most of the Broads. Recent restoration has removed large areas of scrub to restore open fen and restored large lengths of ditches. Modern management is now focussed on enhancing the ecological quality of the site and includes rotational fen cutting, commercial reed and sedge cutting, pond digging and Highland cattle grazing. The site is most famous for its botanical quality, in particular the largest colony of fen orchid in the UK but as further survey work is done it is also becoming appreciated as nationally important for its invertebrate fauna that includes 14 RDB moth species, 32 RDB beetles and 23 RDB flies.
