The Forestry Commission increases the value of woodlands to society and the environment. It manages publicly owned forests and regulates public and private forests in England. It conducts scientific research, promotes forest outdoor recreation activities, and works to improve the biodiversity of England’s forests. Felling is generally illegal without obtaining a licence from the Commission. It was established in 1919 to expand Britain’s forests and woodland after they were severely depleted during World War I. It is now organisationally split into three divisions – Forest Services, Forestry England and Forest Research (see above).
