This site is on the flood plain of the River Ouse, and has fields separated by ditches. Variations in salinity from brackish to spring-fed, together with periodic clearing of ditches, produce a variety of habitats. The site is home to a diverse array of invertebrate fauna, especially Coleoptera. There are also rare Mollusca, Diptera and Lepidoptera.
