Vegation Composition

According to PAIVA recommendations (2001), in the composition of the vegetation of a square if do not have to introduce toxic species or that they present physical danger to the users and nor so little fruitful species, therefore they can cause some upheavals to its users (figure 2). As, it was observed that, species: Euphorbia you ingest laciniosa Bromlia, Mangifera indicates had been found with sufficient frequency. Inadequate species for square: Laciniosa Bromlia SOURCE: IT HISSES, M.L. 2006. In accordance with SAINTS (2001), species that present system to radicular superficial in reduced area and depending on quality of the used material, the pressure exerted for the roots will be able to provoke trincas and to compromise the space where if they find. Species was evidenced that as the Mangifera indicates rigid Parapiptadenia and other identified individuals do not compromise that physical space when observing (figure 3), see that the roots are provoking the particle disaggregation of the ground, this process if it intensifies during the rainy period. Figures 3? Species not identified that presents voluminous roots: SOURCE: IT HISSES, M.L. 2006.

The species diversity does not determine the identity of a space COAST et. al (1996). The 15 found species, in the square probably are proceeding from random plantios carried through by employees of the city hall who were unaware of the techniques of arborization of an area. Species with 3 and 2 individuals had been found representing (4.90%) and 5 species with only 1 individual representing 4.09% of the total of plants. Another indication that discloses the lack of knowledge and planning are that 17.21% of the trees and shrubs divide the space in one same seedbed (figure 4), other well next ones to the others without mensurao of espaamento. Mangifera indicates Psidum guayava, rigid Parapiptadenia, Hibiscus schizopetatus, Euphorbia you ingest and other strangers had been distributed of random form in the seedbeds.
