【 摘 要 】

Universitas Indonesia's urban forest is a part of Universitas Indonesia's campus area, which covered 192 hectares from total 320 hectares campus area. Universitas Indonesia as a green campus has many green open spaces that distributed throughout campus and consists of several tree species. The age of the most vegetation in both urban forest and green open space has been 30 years old. This condition required routine management to evaluate tree health and risk. Some routine management has been conducted which consist of pruning and eliminating dead trees followed by replanting of new trees. This management aims to reduce the risk posed by trees related to community safety and for keeping environmental sustainability. The method that we used to assess the tree risk were visual tree risk assessment (VTA) based on biological characteristics of the risked tree. The result showed that there are four major species that need more routine management and had a higher percentage of managed trees during 2018. Those species were Acacia mangium, Hevea brasiliensis, Enterolobium cyclocarpum, and Delonix regia.
