The Beverley Brook rises at Cuddington Recreation Ground and flows along the western side of Sparrowfeld, marking the boundary between Kingston and Sutton.
Both Boroughs have designated their respective sides, and associated habitats and woodland, Sites of Importance for Nature Conservation. Part of the Brook is inaccessible, but it can be appreciated from the Gas Holder Wood and Green Lane.
For many years the Beverley Brook was heavily polluted by waste from Worcester Park Sewage Works. Since its closure, the water quality has improved, although flow levels are maintained by treated water from the Hogsmill Sewage Works. Aquatic life has slowly returned, as have riverine birds, four of which are known to have bred along this stretch. The more interesting species you are likely to see are Little Egret, Kingfisher and Grey Wagtail.
Near Worcester Park Station, the Brook has a flood storage area known as Back Green. Along with Malden Green, this is one of the last surviving areas of local common land, and the two were connected until the railway was built. Now closed to the public, but visible from the road, this has become an important wildlife site.
