Roadside shade trees are an essential component of urban green openspaces, contributing significantly to environmental quality throughecological, aesthetic, and social functions. The composition of treespecies along urban road corridors influences the effectiveness ofvegetation in reducing air pollution, moderating urban temperatures,and improving environmental comfort. This study aimed to analyzethe species composition of roadside shade trees in supporting urbanenvironmental quality in Bima City, Indonesia. A descriptivequantitative survey was conducted on three major road corridors,namely Gadjah Mada Street (Penaraga Village), Sultan MuhammadSalahudin Street, and Gadjah Mada Street (Penatoi Village). Datawere collected through field observations, species identification, treeinventory, and documentation. The collected data were analyzeddescriptively based on species composition, number of individuals,and species distribution across the study sites. The results identified327 individual trees belonging to 11 species, namely Albizia saman,Azadirachta indica, Swietenia mahagoni, Terminalia catappa, Parkiaspeciosa, Polyalthia longifolia, Dalbergia latifolia, Delonix regia,Pterocarpus indicus, Ficus benjamina, and Acacia auriculiformis.Albizia saman was the dominant species, accounting for 149individuals (45.57%), followed by Azadirachta indica (66individuals), Swietenia mahagoni (43 individuals), and Terminaliacatappa (35 individuals). The highest species richness was recordedon Gadjah Mada Street in Penaraga Village, where eight species wereidentified. The dominance of broad-canopy tree species indicates thatthe roadside vegetation in Bima City has considerable potential toenhance urban environmental quality by providing shade, improvingthermal comfort, and supporting other ecological functions. Thefindings of this study provide baseline information for urban treemanagement and may serve as a scientific reference for developingsustainable urban green open space policies in Bima City
