Arborização urbana em Praças de Alagoinhas, BA, Brasil

Abstract

Benefits from urban afforestation are directly conditioned to their overall planning quality. Although the use of natural elements as tree species may result in innumerous advantages within urban areas, factors such as the not fulfillment of technical standards and lack of knowledge on the species planted in such environments may result in many problems, especially in cities with increasing urbanization where well planned spaces are in growing demand. This work was carried out with the objective of evaluating quantitatively and identifying the main problems related to the management of afforestation in squares located in the center of Alagoinhas, State of Bahia, Brazil. For this, eight squares were selected at the center of the city and a census was carried out for identification and identification of the species, analysis of phytosociological parameters, Absolute and Relative Density and Frequency, and diagnosis of these plant individuals considering the following aspects: state general, general equilibrium, phytosanitary, injuries, surroundings and interferences, and the actions performed. A total of 162 individuals belonging to 29 species were evaluated. The most frequently species observed was Delonix regia with 62,50% records within the evaluated town squares, and Ficus benjamina being the species with the highest number of observed individuals in 50% of the squares. The most damaging problem observed in the squares was the performance of severe prunings that do not follow technical criteria and compromise the health, vigor and aesthetics of the trees. The evaluated individuals require a management planning for conservation that may eventually include staff training to ensure their correct maintenance and health status.
