Beddington Farmlands is a 161 hectare site in the heart of the Wandle Valley Regional Park. For over a century, various forms of sewage treatment and disposal have been carried out here.

Together with Beddington Park and Mitcham Common, it forms one of the largest green spaces in south London.

David Lindo, BBC broadcaster and writer, described it as, “The sleeping giant of London’s natural history world.”

Beddington Farmlands is an important area for wildlife, currently being restored to become a flagship nature reserve with many habitats, and classified as a Site of Importance for Nature Conservation and Metropolitan Open Land.

There is a birdwatchers’ group – Beddington Farm Bird Group (BFBG) – formed in August 1992, which sometimes offers guided tours of the area.
