Urban forests are essential for maintaining the quality of life in cities and play an important role in the conservation of flora. Thus, the aim of this study was to realize a partial inventory of urban trees in the city of Lavras - MG, with the survey of its floristic composition and the investigation of the use of native species. For that were covered 43.34 km of public roads in the city, distributed in 10 neighborhoods. A total of 415 trees and shrubs individuals were cataloged belonging to 43 species, 39 genera and 26 botanical families. The species with the highest relative frequency were Murraya paniculata (L.) Jack. (20.0%) Poincianella pluviosa (DC.) LPQueiroz (15.7%) and Lagerstroemia indica L. (12.5%). It was found that 37.8% of individuals are species of shrub behavior. The individuals were classified in 19 native species, these seven are indigenous forest remnants of Lavras - MG. It is concluded that it is necessary to improve the planning of urban forestry, prioritizing the use of appropriate species and preferably native of the region.
