Qualitative and quantitative evaluation of urban afforest in the central district of Salto-SP

Abstract

Initially populated by Guayana Indians in the early years of the 17th century, the downtown area of Salto, located in the country of the state of São Paulo, Brazil, has great historical-cultural value and preserves a lush green area. In order to map and assess the afforestation of this area, a census-type survey was carried out from February to September 2017, evaluating all individuals available: trees, shrubs and palm trees planted on sidewalks and flowerbeds. Specimens of all individuals were collected, photographed and georeferenced, and exsicates were assembled to identify the species. The results showed a total of 1,240 individuals belonging to the 35 botanical families, being 39,68% (n=492) native and 60,32% (n=748) exotic. The problems encountered are related to the lack of planning in the street infrastructure, in which 688 individuals are in cemented areas, 232 individuals damaged the sidewalk, 138 have no room for growth and 229 have the canopy in contact with the wiring. This data demonstrates that the afforestation present in this site requires management and lacks infrastructure.
