Lewes Brooks is a 339.1abbr=offNaNabbr=off biological Site of Special Scientific Interest south of Lewes in East Sussex.[1] [2] The Falmer-Glynde and the Ouse valleys meet in Lewes Brooks, and the Upper and Lower Rises are the remains of the chalk uplands eroded by the Ouse.[3]
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 water beetles. There are also rare snails, flies and moths.[4]
