The wood was a forest before the Norman Conquest and then became common land as wood pasture, rather than thick woodland. It was enclosed in the early 19th and was used as a source of commercial timber production – planted with oak and pine, which was then felled. It was sold to the local authority in the late 1930s, used by the military in the Second World War and then opened to the public, under local authority management. It is a Site of Special Scientific Interest and a local nature reserveBroombarns Wood. This is an older wood.
