Tracheophyta MagnoliopsidaFagaceaeQuercusQuercus robur


A long-lived, deciduous tree of high forest, coppice woodland and ancient wood-pasture. It grows on a wide range of soils, typically those which are heavy and fertile, but does not thrive on thin soils over limestone or acidic peat. It is fairly tolerant of waterlogging, growing at fen margins and in Alnus woodland. It is very widely planted in hedges and woodland. 0-450 m (Talgarth, Brecs.).
