Until the 1970s, the Royal Forest and Bird Protection Society remained the only New Zealand environmental group. However, in October 1971 the New Zealand Government proposed to harvest large areas of native South Island lowland beech forest with half the cleared area to be converted to exotic "Pinus radiata". Along with the Save Manapouri campaign, the native forest harvesting prompted more public awareness of conservation and the formation of new environmental groups such as the Beech Forest Action Committee. In response to the native forest harvesting, on 4 July 1975 Forest & Bird and Beech Forest Action Committee started the Maruia Declaration as a public petition demanding an end to native forest logging and legal recognition of native forests. The Maruia Declaration was submitted to the New Zealand Government in 1977.
