Abstract
Urban forests function effectively as climate controllers, including functioning as lowering temperature, absorbing solar radiation, and breaking wind flow. The selection of potential tree species with regional typologies and their designation for urban forest development is an effort to reduce these negative impacts. The purpose of this study was to identify the diversity of tree species in the urban forest of Polewali Mandar Regency Square. This research was conducted in March-May 2023 in the town square area of Polewali Mandar Regency. The research method is the census method, namely by recording all types and number of trees that grow above the ground. There were 8 plots with the size of each plot of 20 m x 20 m.
