Preservation of a large Chinese banyan on a construction site

Research output: Contribution to journalArticle

Abstract

Trees on buildings sites are routinely damaged or felled in Hong Kong due to negligence and lax control. In an unprecidented move, the government required the developer of a large well-wooded lot to retain one large Chinese Banyan (Fiscus microcarpa) tree and take necessary measures to ensure its long-term survival. The size, fine condition, species rarity, longevity and setting justify its preservation. Great costs (about US$120,000) was needed mainly to construct a 18 m diameter and 10m deep reinforced concrete planter in site above five stories of shops and carparks. Routine arboricultural inputs, such as phased pruning of crown and roots, installation of aeration and irrigation facilities, and fertilization, are prescribed. Special precautions, including regular monitoring of watering and fertilization to minimize risks of physiological stresses, are justified in view of the costly preservation.
