The Borough of Runnymede contains a wide diversity of habitats including 5 Special Sites of Scientific Interest and  a Special Protection Area together with 2 nature reserves and 35 Sites of Nature Conservation Importance. Among these is Langham Pond.

The Pond was created when the meandering River Thames formed and abandoned an oxbow lake. Its status as a wetland Site of Special Scientific Interest (SSSI) was first notified in 1975 and later reviewed under Section 28 of the Wildlife and Countryside Act 1981 when the protected area was extended to 64 acres within Runnymede as managed by the National Trust.

The pond and associated meadow form a habitat considered unique in Southern England and of international importance for nature conservation. The flora and fauna include nationally scarce plants and insects including a species of fly unrecorded elsewhere in the United Kingdom as well as dragonflies. Pond plants include duckweeds, foxtail grass and water parsnip.

Breeding birds in the surrounding deciduous woodland include woodpeckers, kestrel, nuthatch and cuckoo. Surveys suggest the population of British breeding birds has been stable over the last two decades.
