Trees are at risk of collapsing during typhoon and rainy seasons.
A local university's innovation team has developed a system to monitor this risk by collecting data on tree health.
By scanning the tree trunk in a circular motion, both up and down, a 3D "body check" report is generated instantly.
This is followed by the installation of sensors to facilitate long-term monitoring.
The system has now been applied to over 10,000 trees across Hong Kong.
HERMAN CHAN, Managing Director of LeafIoT Technology Ltd.:"We based on the leaning trend, the sudden change, so as to capture all the health symptoms and share (with) our users, and based on our previous experience, we have already captured more than 1.4 billion tree health indexes, and we've transformed them into more than 4,000 health alerts. And finally, we've successfully prevented more than 1,400 tree failure issues."
Developed by a team from the Hong Kong Polytechnic University, this system recently participated in a business competition organized by the Trade Development Council to expand its network.
Collaborations have begun with local government departments, schools, property management companies and institutions in Japan and Singapore.
Over the past year, about 390 reports of tree collapses have been recorded.
Tree safety issues have become more urgent during typhoon and rainy seasons.
Jim Chi-yung, chair professor and a Geography and Environmental Science advisor at the Education University of Hong Kong, has called for additional measures to support precious trees and prevent collapses.
He emphasised that soil quality and volume are essential for root development.
Problems associated with planting large trees in areas with inadequate soil conditions have remained unresolved in the city for years.
He also suggested that the authorities consolidate tree management to enhance efficiency.
