ESPÉCIES UTILIZADAS NA ARBORIZAÇÃO URBANA NO MUNICÍPIO DE JAÚ, SÃO PAULO, BRASIL

Abstract

There are several benefits that urban afforestation promotes to the population and fauna of the urban centers. Thus, studies that seek to assist in the planning of urban afforestation are extremely important because they enable the proper management of this heritage. The present study aimed to inventory the species used in urban afforestation in the municipality of Jaú, State of São Paulo and observe the environments in which they occur, habit, origin, threatened and invasive species. Were observed 335 species in urban environments and the richest families were Fabaceae and Arecaceae. Tree species are the most common, accounting for 65.97% of the total as well as exotic species (175 spp. - 52.23%), however, it is worth noting the high number of municipal native species (66 spp. - 19.70%). In addition, was found that public roads and squares harbor the largest number of exclusive species, however, most of them are exotic species. It was also found that 20 species are threatened with extinction, of which 12 are native, at least from Brazil and 47 species are considered invasive. Therefore, it is evident that even the number of species observed is high, the urban afforestation in the municipality of Jaú harbor many alien and invasive, but which can be gradually replaced by native municipal and regional species. It is worth mentioning the presence of municipal native species and endangered species, showing the important role that urban afforestation can play.
