Urban areas are constituted by a patch of physical, ecological and social spaces. By the increasing urbanization, the conversion of green areas in cities tends to grow as well. The goal of this work was investigate variations in the occurrence and distribution of tree species in suburban and urban areas in Três Lagoas municipality, MS (Brasil). This study was conducted from July to November/2012, when four parallel transects were randomly selected and spaced at least by 500 m away from each other. The sampling was carried out systematically in interspersed blocks (200 m), where it was recorded: a) the number of trees, b) its species, c) its origin, d) its DBH, e) its height, f) time and place. I found 336 individuals, from which 44 tree species belonged to 21 families in urban and suburban areas. Also, 14 (32 %) of the species recorded were exotic and 30 (68%) were native ones. The wide variation of species density and richness shows that trees occurrence on sidewalks depends highly on the residents decisions. Future studies concerning the dynamic of vegetal community in urban areas should consider the local origin of the species according to its vegetal physiognomies rather than only its biome where they occur.
