Kennet and Lambourn Floodplain is a 23.4-hectare (58-acre) biological Site of Special Scientific Interest in six widely separated areas in the floodplains of the River Lambourn in Berkshire and the River Kennet in Wiltshire, England.[1][2] It is a Nature Conservation Review site[1] and part of the Kennet and Lambourn Floodplain Special Area of Conservation.[3] One of the areas, Rack Marsh, is managed by the Berkshire, Buckinghamshire and Oxfordshire Wildlife Trust.[4]
These six areas all have fen or swamp with large numbers of Desmoulin's whorl snail, which is listed in the British Red Data Book as it is a nationally rare and declining species. One of the areas, Eddington Marsh, also has unimproved species-rich grassland with several nationally scarce invertebrates, such as the flies Pherbellia griseola, Psacadina verbekei, Platypalpus niger and Oxycera morrisi.[5]
