Levantamento das espécies arbóreas e percepção sobre a arborização da praça centenário em Maceió, AL

Abstract

The forestation of public streets, squares, squares and parks of modern cities is a necessity for the lives of the people who live in them. In the sphere of the ecological aspects of the squares of a city that are related mainly to the microclimatic effects, it is considered of paramount importance the knowledge of the vegetation existing in this urban space. This work had as objective to make a survey about the floristic composition of the tree species, their respective dispersion syndromes, and the perception about the importance of the arborization by the visitors of the Centenário square, located in the municipality of Maceió, AL. Data collection for this work was done through on-site visits in the square. Where all trees with CAP (chest circumference) ≥ 15 cm were measured. The data were organized into a table containing the common name, scientific name, family, origin (native or exotic), and mode of dispersion. To obtain data on perception, a questionnaire with eight objective questions was used with the attendants of the square. It was verified that the population has a good understanding about the perception of urban afforestation, considering that they affirmed social value as the most important benefit, since it provides the same leisure, interaction with family and friends. In the floristic survey, the most representative family was Fabaceae with 8 species. Regarding the predominance of native and exotic species, the native one was the one that most predominated in Centenary Square, which shows that the importance of the native fauna was taken into consideration in the arborization of the square. It was also observed that the syndrome of dispersion with higher incidence was autocoria / zoocoria, which shows that being an open area facilitates its dispersion.
