SPECIES SELECTION AND PLANTING DISTANCE OF URBAN TREES IN KUCHING NORTH CITY COUNCIL

Urban trees play important roles in urban environment such as urban biodiversity, energy conservation, urban noise, urban hydrology, traffic calming effect, microclimate and temperature, and removal air pollutants. Species diversity index (SDI), diameter breast height (DBH) distribution, soil physical analysis, soil pH analysis, air temperature comparison between asphalt zone and under shade tree, are the ways to measure the significance impact to the environment. The main aim of this project is to assess the distance of trees and the species selection in Kuching North City Council. The diversity of trees at this place consists of the old plant which had been planted and the new planted trees and both of them will be compared. The most abundant species planted are Cinnamomum iners, Andira surinamensis and Filicium decipiens due to its ornamental attributes. The urban planted trees should full filled the main criteria to be selected and the planting distance is considered for the development of crown and root of planted trees
