Identification of suitable trees for urban parks and roadsides in Iskandar Malaysia
Urban trees provide a number of benefits, mainly for environment, community, and economy, but can also be harmful to property and human lives. Urban trees planted at roadsides with low endurance rate and unhealthiness increase the risk of tree fracture and fall which is hazardous to motorists and pe...

Urban trees provide a number of benefits, mainly for environment, community, and economy, but can also be harmful to property and human lives. Urban trees planted at roadsides with low endurance rate and unhealthiness increase the risk of tree fracture and fall which is hazardous to motorists and pedestrians. Overhanging limbs, on the other hand, can obscure streetlights, signs and traffic signals and affect road users’ vision in vicinity. These situations contribute to the cumulative maintenance burden to the local authority. This makes the study of maintenance level and suitable location for urban tree planting important. An appropriate maintenance and location can be suggested for assuring a healthy, safe, resilient and long-term survival of urban trees. Urban tree field data from two local authorities in Iskandar Malaysia region (located in the southern part of Peninsular Malaysia), Johor Bahru City Council, and Pasir Gudang Municipal Council, were obtained to achieve the objective of this study.
