 Many organisations, including local authorities, youth organisations, schools, businesses and communities supported the campaign by planting or donating trees, or making land available.The Forestry Commission donated some 90,000 trees to schools and a further 70,000 for joint projects with local authorities, as did other organisations including the Crown Estate Commissioners.The Royal Mail also marked the campaign by issuing a 9p commemorative stamp, first issued on 28 February 1973.
