After the Second World War, Hart worked for Major Charles Penrhyn Ackers, ex
High Sheriff of Gloucestershire and owner of the Huntley Estate and Huntley Manor, first as land agent and later as manager of Forest Products Ltd and Woodland Improvement Ltd, companies associated with the estate. Hart was inspired by Major Ackers who had a national reputation as a
silviculturist, was the author of a standard book on forestry, and planted specimens of many varieties in the park of his home at Huntley Manor. In 1948, Hart co-founded and later became secretary and president of the Forest of Dean Local History Society. He purchased nine acres of land surrounding the mound of the Old Castle of Dean at
Littledean, said to be the first castle built beyond the Severn against the Welsh, donating it to the
Dean Heritage Centre in 1982. He donated his archives of document transcriptions to the
Gloucestershire Record Office. His other books and papers became the Cyril Hart Collection, housed at the
Forestry Commission offices at Bank House in Coleford. In postwar years he became chairman of Forest of Dean Newspapers, a privately owned company which published the local papers covering the area. In 1981 he was appointed
OBE for services to forestry. In 1999 he was honoured by having The Forest of Dean Arboretum near
Speech House was named the Cyril Hart Arboretum in his honour in 1999. ==Authorship==
