Qualitative and quantitative analysis of urban trees in a neighborhood of Bauru, São Paulo, Brazil.

Abstract

The rapid growth of cities has resulted in several environmental problems. Seeking to minimize such problems, the afforestation in urban areas has become indispensable and it is considered a quality of life parameter for the population. In this context, the present study aimed to diagnose the status of urban trees of the neighborhood Jardim Brasil, in the city of Bauru-São Paulo, Brazil, through a qualitative and quantitative survey of shrubs and arboreal individuals. It was possible to record 23 families and 41 species in a total of 510 trees and shrubs, from which 11 were found dead. The neighborhood has a relatively low variety of species, mostly exotic ones (60.98%). The most common species are: Licania tomentosa (31.87%), Caesalpinia peltophoroides (11.16%), Lagerstroemia indica (9.56%), Murraya paniculata (6.57%) and Terminalia catappa (5.98%). Most of the problems found are due to the lack of planning of urban forestry, which creates conflicts with the electrical wiring and construction; however, few are the cases of conflict with the street lighting and traffic signs. We also highlight a large number of trees attacked by termites and ants (59.34%). Studies like these become useful for decision making and planning of urban trees of a city.
