Bricket Wood Common is a SSSI site and consists of diverse habitats including ancient semi-natural woodland; hornbeam coppice woodland; wet lowland heath/acid grassland; and ponds and seasonal streams. The Common supports an array of wildlife including great crested newts, butterflies, heather, fungi, blue bells and Heath Spotted Orchids.

The site consists of an area of around 78.5 hectares and is situated within the boundaries of the M25 and the M1. Its location, history and diversity of habitats ensure that the open space is highly valued by the local community. A 10 year Green Spaces Action Plan sets out how the common will be developed to allow a co-ordinated and organised approach to management and conservation, and to meet Natural England’s aim of bringing all SSSI’s into a favourable condition.
