Heritage tree

A heritage tree is typically a large, individual tree with unique value, which is considered irreplaceable. The major criteria for heritage tree designation are age, rarity, and size, as well as aesthetic, botanical, ecological, and historical value.^[1] Heritage tree ordinances are developed to place limits upon the removal of these trees; the ordinances are oriented towards a specific tree, not a woodland.^[2] Heritage trees in Singapore are protected by law under the Heritage Trees Scheme adopted on 17 August 2001. The oak is depicted as England's heritage tree.^[3]
