The section of the brook between Lyndhurst Park and Watling Park is part of the Silk Stream and Burnt Oak BrookSite of [Nature Conservation Interest|Site of Borough Importance for Nature Conservation], Grade II. Downstream of Lyndhurst Park, it passes through a narrow belt of mown grass which is left wild close to the brook, with scattered trees and common wild flowers on the banks. In Watling Park the stream mainly follows a natural course and crack-willows, hawthorn and alder form a woodland corridor for wildlife. Grey wagtails often forage among the pebbles of the brook.
