Abstract

The diversity of tree population is important considerations in terms of the ability of the urban forest to withstand stress. The planting of mixed species of tree on city streets is certainly not a new concept, and it is generally recommended that no more than 10% of the trees be from any one species should be planted. Maintaining a good diversity of species in any landscape planting will help to ensure that insects, diseases, and changing environmental conditions will not, at some point, result in widespread problems. A survey was carried out to assess the diversity of urban trees planted in four protocol roads such as Tun Abang Haji Openg, Tunku Abdul Rahmad Yaakub, Tun Ahmad Zaidi Adruce and Bako roads. Species diversity index (SDI) of street trees in four protocol roads is 10.04 and is considered relatively low. The 3532 trees enumerated in the study area include 27 species. The most abundant species is Michelia sp., followed by Cinnuniomum iners. Other popular choice is Cassia siamea and the Tabebuia pal/ida species due to its ornamental attributes. The implications of species diversity and importance of species selection are discussed
