Harpsden Wood is a 29.4-hectare (73-acre) biological Site of Special Scientific Interest south of Henley-on-Thames in Oxfordshire.[1][2] It is owned by the Woodland Trust and is open to the public.[3]
Most of this ancient wood is on acidic clay with flints, although some areas are on sandy clay or chalky silt. The acid soils have a sparse understorey but there is a diverse ground flora in the calcareous areas. Orchids include broad-leaved helleborine, green-flowered helleborine, bird's-nest orchid and narrow-lipped helleborine.[4]
