Composition and characteristics of trees in private residencies in Hong Kong

Abstract

Trees in the gardens of a suburban residential neighbourhood has been studied in terms of species composition, habitat condition, amenity characteristics and tree performance. The detailed evaluation of 2345 trees in 842 sample households showed a diverse range of species of which only seven are indigenous, with a clear domination by a few popular ones and a wide scattering amongst the remainder. Whereas broadleaf trees are the most common group, a few conifer and palm species are heavily subscribed. Trees with attractive foliage and which provide an effective shade have been more generously adopted in preference to flowering species. A sizeable proportion with large final dimensions has been cultivated despite the generally confined growing space. Most trees are vigorous and well maintained. A number of management issues and long-term prospects have been discussed.
