Abstract The UMK-Tropical Rainforest Research Centre (UMK-TRaCe) in Pulau Banding, Perak, Malaysia, is an environmentally sensitive research facility that aims to integrate technology with nature. However, certain tree components have resulted in harm to the buildings and infrastructure within the center. This study presents a comprehensive tree risk assessment conducted at UMK-TRaCe using the standardized ISA Basic Tree Risk and Hazard Assessment Form. The assessment evaluated all 37 individual trees surrounding the facilities area comprising 19 species from 15 families, analyzing various parameters such as site factors, tree health, species proKile, load factors, tree defects, and conditions affecting the likelihood of failure and risk categorization using a standardized survey form of the International Society of Arboriculture (ISA). The results show that 24.3% of the trees (9 trees) fall under the category of potential tree risk hazard, while 43.2% (16 trees) are considered low risk. Notably, 21.6% (8 trees) are classiKied as high-risk, with Alstonia scholaris identiKied as the most hazardous and high-risk tree. These Kindings hold signiKicant importance for the management of UMK-TRaCe, as they provide valuable insights for planning and maintaining the health of trees, as well as ensuring the safety of the surrounding environment. The study recommends the implementation of a comprehensive tree risk management plan, including regular monitoring, targeted maintenance, and, if necessary, the removal or replacement of high-risk trees. By addressing tree risks, UMK-TRaCe can continue to serve as a guardian of the forest while ensuring the safety and well-being of its visitors and infrastructure.
