The woodland areas contain mature oak, birch, and holly, providing significant canopy cover and shelter for local bird populations.
Cannon Hill Common is a 55-acre public open space in the London Borough of Merton characterized by its mixture of ancient woodland, grassland, and a significant fishing lake. The site is a designated Site of Importance for Nature Conservation, housing diverse habitats including acid grassland and oak-birch woodland. The lake serves as the focal point for angling enthusiasts and local wildlife observation. The common features a network of surfaced and informal footpaths suitable for year-round walking. It functions primarily as a neighborhood green space managed by Merton Council to balance recreational use with ecological preservation. The land historically formed part of the estate of Cannon Hill House, which was demolished in the mid-20th century.

Check local signage for specific rules regarding fishing permits and seasonal restrictions.
Do not attempt to feed bread to the waterfowl, as this damages the water quality and harms the birds.
Keep dogs under control, remove all litter to protect wildlife, and adhere to local angling bylaws.
