 This site is a large, ancient, semi-natural, broadleaved woodland with a predominantly high forest structure which is unusual in South West Britain.Over the majority of the site, where soils are poorly drained but not waterlogged, the major canopy-forming tree is pedunculate oak ("Quercus robur"), with ash ("Fraxinus excelsior") being locally common and distributed throughout.Hazel ("Corylus avellana") is the commonest shrub and occurs throughout.
