Floristic and qualitative evaluation of the species Mangifera indica L. In the places of Santarém, Pará

Abstract

Urban afforestation is described as one of the most important components of the urban ecosystem and thus should be a permanent concern of any planning due to the benefits that are provided in its consequence. The objective of this study was to carry out a quantitative survey of the tree species present in 11 plazas in the municipality of Santarém and to characterize the mangueiras (Mangifera indica L.) in these squares. 209 individuals were inventoried, and 43% of the total inventoried trees are mangueiras. The high percentage of mangoes shows that the afforestation of the squares analyzed does not favor the preservation of the local biodiversity, being more propitious to the attack of xylophagous organisms. The squares present a diversity of species, however, many individuals of the same species, which is not desirable because it makes the population more susceptible to a population decline due to the attack of plagues and diseases. For qualitative evaluation, visual analyzes of the physical aspect of the trees were performed, considering: signs of diseases, signs of termites, cracks in the trunk and hollows. Of the 90 mangueiras analyzed, 8 presented signs of diseases, 23 had termite signs, 5 presented cracks and 2 presented hollows. In view of the above, there is a need for better planning, especially in relation to the diversity of the species used and their maintenance.
