CPRE, The Countryside Charity, formerly known as the Campaign to Protect Rural England, is a charity in England with over 40,000 members and supporters. Formed in 1926 by Sir Patrick Abercrombie to limit urban sprawl and ribbon development, the CPRE (until the 1960s the Council for the Preservation of Rural England and from then until 2003 the Council for the Protection of Rural England) claims to be one of the longest running environmental groups. CPRE campaigns for a "sustainable future" for the English countryside. They state it is "a vital but undervalued environmental, economic and social asset to the nation." They aim to "highlight threats and promote positive solutions." They campaign using their own research to lobby the public and all levels of government.
