Análise quali-quantitativa da arborização urbana e seus fatores ecológicos em uma praça de Teresina-PI

Abstract

Green areas are fundamental to the social, environmental and economic balance of cities, providing benefits such as improving air quality and reducing temperatures. However, the afforestation of squares can present challenges related to social, economic and environmental factors, therefore requiring more effective planning and management to ensure their adequate and sustainable functioning. The present study aimed to evaluate the afforestation of Praça Santa Sofia, in Teresina-PI, and the environmental services offered by it. As a result, 7 botanical families and 15 species were identified, totaling 51 individuals, highlighting Mangifera indica L., which exceeded the recommended frequency limit of the same species. Most of the trees in the square are over 5 meters tall and have globe-shaped crowns. In the phytosanitary aspect, it was found that some trees showed inadequate recovery due to mechanical damage caused by poorly carried out pruning. Furthermore, conflicts with urban infrastructure were recorded, such as tree tops coming into contact with the roofs of commercial establishments. Thus, the results indicate that the afforestation of the square is predominantly composed of exotic species, suggesting the need for adjustments in pruning and species planning. Therefore, it is concluded that adequate phytosanitary management and careful tree planning are important, aiming to maintain ecological balance, plant health and improve urban space for the local community
