Hops growing on Downs Bank continued until the 1940s, and there was also cattle grazing until 1959. The area was subject to purchase with the help of a public subscription and it was given to the National Trust by John Joule in 1950 as ""an offering for victory in the 1939-45 War, and as a memorial to those who died"" – apparently on the grounds that it had originally been common land, and should thus be open again to local people. However, after 1950 the lack of grazing caused its characteristic heathland to decline, as bracken and birch were allowed to invade.
