Langham Pond is a 26.7-hectare (66-acre) biological Site of Special Scientific Interest north of Egham in Surrey, England.[1][2]
The pond and its surrounding alluvial meadows on chalk are a unique habitat in southern England. The pond is the remains of an oxbow lake, formed when a meander of the River Thames was bypassed. It contains all four British duckweeds, three nationally scarce plants and a species of fly which has been found nowhere else in Britain, Cerodontha ornata.[3]
