Resumo:
The urban forestry minimize the effects of the microclimatic instability and also the atmosoheric, hidric, and visual pollution wich affect the urban life quality. Resulting thus, the necessity of better planning and maintenance of urban threes. In this study, an inventory of street trees was carried out within an error limit of 15% and the 95% probability level, with the main purpouse of,analise the existent relation between the ne- cessity of trees care and the characteristics of arborization planning. The diversity of species and the physical and sanitary conditions of street trees were studied as influent factors in the urban fores- try management. To conclude, it is possible to minimize the maintenance costs and improve the urban plantings through: il) adequate seletion of species; (2) using the adequate form and size to the disponible space; (3) improvement of the plant quality and; (4) improvement of the today adopted tree care.
