This 560-acre (277ha) complex of old commonland stretches almost 6 kilometres south to Peppard Common. The varied soils and past land gives rise to a rich mix of habitats and wildlife. Many of the heathland areas have been colonised by secondary woodland. Digging of clay for the old brick-making industry has led to some valuable ponds and wet areas which are a magnet for wildlife. The site is now used for forestry and recreation.
