Penn Wood
Penn Wood is owned and managed by the Woodland Trust and is 436 acres adjoining Common Wood to the North and East. It is one of the largest semi-natural ancient woodland and wood pasture in the Chilterns, is rich in wildlife and flora including at least 10 plants not commonly found in the county. It has a good bird population and a number of nationally scarce invertebrates. It includes the remains of an ancient beech and a veteran oak, along with a scattering of trees dating back more than 200 years.
Common Wood was purchased by the Penn and Tylers Green Residents Society in 2002 following an extensive public campaign. With support from the Woodland Trust, the Chiltern Society and the Lottery Heritage Fund, the Society has been able to safeguard the wood for the benefit of the local community. It is committed to providing open access to all, and has set about an extensive management programme of both the natural habitat and the paths and access points throughout the wood.
