The town people have resisted many attempts to enclose parts of the common land, including by the vicar, Rev. Thomas Whateley in 1799, Miss Isabella Fleming in 1869 (who wanted to stop nude bathing at Odney) and the Odney Estates in 1928 who wanted to enclose Odney Common. The Maidenhead and Cookham Commons Preservation Committee was formed and raised £2,738 to buy the manorial rights and the commons which were then donated to the National Trust by 1937. These included Widbrook, Cockmarsh, Winter Hill, Cookham Dean Commons, Pinkneys Green Common and Maidenhead Thicket.
