Heritage Trees in Singapore are mature trees specially selected under the Heritage Trees Scheme adopted on 17 August 2001, by the National Parks Board (NParks). The Heritage Trees Scheme was proposed by the Garden City Action Committee alongside the Heritage Roads scheme, weaving heritage trees into the street landscape. It is part of a nationwide drive in tree conservation efforts not just within nature reserves, parks, and tree conservation areas, but also anywhere else in the urban and rural environment of Singapore. The mission statement of the Heritage Trees Scheme emphasises the importance of such trees in shaping residents' "sense of permanence and identity" to the landscape, given that these trees have often existed for centuries. The Heritage Road Scheme aims to conserve the scenic and significant tree-lined roads of Singapore. In 2006, the following five roads were gazetted as Heritage Roads: Arcadia Road, Mount Pleasant Road, Lim Chu Kang Road, Mandai Road, South Buona Vista Road.
