CUGE-ARB-3011 Tree Inspection (Level 1)

Trees growing in urban areas have to withstand multiple environmental stresses. Tropical storms, air pollution, wind tunnels, poor tree pruning, reduced root structure and compacted soils are some of the environmental stresses which weaken urban trees. Urban stress factors inadvertently accelerate the aging process of trees, causing branch, stem and root decay. Branches or even the whole trees may fall over, endangering humans and/or damaging property. Therefore, visual assessment on urban trees has to be carried out regularly in order to identify hazardous trees and to minimise risks.


This two-day course aims to provide learners with background in tree biology and equip them with basic skills for proper tree inspection. An essential feature of this course is the on-site practical where participants will conduct tree inspection under the guidance of the instructor. Proper tree inspection is crucial in mitigating tree failure and will aid tree care professionals in their work. Below are content to be covered in the course.
