It has been declared a Wildlife Heritage Site by West Berkshire Council's Countryside Service, and is described as a quiet site with a network of paths leading through tall pine and broadleaf woodland, ponds, small areas of heather and rich wet gullies.

Of particular significance are the heathland areas which support rare species including slowworms, grass snakes and adders.

[2] The 60-hectare (0.60 km2) site is jointly managed by the Countryside Service, the landowner and Berkshire, Buckinghamshire and Oxfordshire Wildlife Trust.

A feature of this watercourse is Pullens Pond, formed where the brook is dammed by a forest access road within the common.

To the east of this area the brook continues into a small valley, Burghfield Slade, which contains a larger reservoir.
