This research created urban forest management using GIS as the primary instrument to act as a combined technique that allows the locals to participate in the survey. To maintain a sustainable urban green, urban tree management is necessary to reduce complexity and conflict. The initiative used a nature-based solution for tree care depending on species combined with a people-centered smart city approach to better assess tree health in historic urban areas. A total of 4607 records were obtained from the field survey event utilizing a mobile application as a tool. The tree’s basic name, spatial character, position, and potential risk were all gathered during the field survey. As GIS converted the tree’s general or local name into its scientific name, it was able to view and evaluate the data. The findings indicate that trees are most in danger from animals and insects, accounting for 56.39% (2748) of the total risk. Most of them are in areas with poor soil suitability. Through optimized hot-spot analysis mapping, the study recommended that tree care be prioritized. Maps of tree blooming and fruiting indicate the possibility of enhancing the advantages of urban trees in the research region in accordance with their phenological patterns.
