Part of the site is owned by the Yorkshire Wildlife Trust[3] and is managed in conjunction with English Nature. It lies adjacent to the River Derwent between Sutton upon Derwent and Menthorpe. The site, which was designated a SSSI in 1975, consists of a series of neutral alluvial flood meadows, fen and swamp communities and freshwater habitats. It is one of the most important examples of agriculturally unimproved species-rich alluvial flood meadow habitat remaining in the UK. In winter the Ings support internationally important concentrations of waterfowl, in excess of 20,000 individuals, together with nationally important numbers of Bewick's swan, teal, wigeon, mallard, pochard, golden plover and ruff.
