This ancient coppice with standards wood on boulder clay has exceptionally diverse ground flora with several rare species. There are scattered mature oaks and the main coppiced species are hazel, ash and maple. The ground flora is dominated by dog's mercury on heavy soils and bramble on lighter ones.
