Northmoor Hill Wood is an Local Nature Reserve in Denham in Buckinghamshire. It is also of geological interest.[1] [2]
The western area near the entrance has wet clay flora, with alder woodland, sedges, rushes, yellow archangel and star of Bethlehem orchids.[1] Geologically, this is Reading Formation, dating to the Tertiary period. The eastern part is chalk, and an old chalk quarry exposes layers dating to the Cretaceous period.[3]
There is access from Tilehouse Lane opposite Denham Aerodrome, and the site has a car park.
