Update on Transition to Planting of More Wind-resistant Trees in View of More Extreme Weather Conditions

Ms Joan Pereira asked the Minister for National Development in view of stronger winds expected from more extreme weather conditions, whether the Ministry can provide an update on the transition to planting more robust tree species that are less prone to uprooting and breakage.

The National Parks Board (NParks) has in place a comprehensive tree management regime that enhances the resilience of its tree population against intense rains and winds. This includes a rigorous tree inspection and maintenance regime that is aligned with the best practices of the International Society of Arboriculture, and complemented by the use of technology to improve diagnostic capabilities and enhance inspection processes.

In tandem, NParks implements pruning to remove weak, dry or overgrown branches, to improve their structure and balance and ability to withstand severe weather conditions. Prior to seasons of wet weather, NParks also undertakes targeted crown reduction on mature trees.

NParks has also been replacing diseased and storm-vulnerable tree species with hardier species which are more suited to Singapore’s weather and urban conditions. For example, the population of Sea gutta (Planchonella obovata) and Shore Laurel (Neolitsea cassia) in parks, gardens and roadside verges managed by NParks has increased from around 25,400 to around 46,500 from 2017 to 2023.
