Analysis of urban forest and available areas for tree planting in public squares in the municipality of Rorainópolis, RR, Brazil

Abstract

With the increase in the urban population, there is an increase in the demand for green areas for outdoor recreation, challenging managers to promote adequate spaces that benefit ecosystems and human health. Therefore, the first step in planning is the diagnosis of the circumstances in which the squares are found. With that, the objective of this study was to evaluate the afforestation of the 7 squares in the seat of the municipality of Rorainópolis-RR. Identification, inventory, phytosociological and phytosanitary analyzes of tree individuals were carried out, measurement of available areas for the implantation of afforestation, with afforestation and calculations of available areas and the deficit in the number of trees. During the visits, it was verified that in all the analyzed squares there were nonconformities, such as: acts of vandalism and lack of preventive maintenance in the arboreal components and in the physical structure. In the 7 squares, 168 trees were observed, distributed in 12 families and 16 species. The main problems found in the afforestation of these squares are related to the lack of maintenance, low species richness, with only 2 species representing 72.61% of the inventoried trees, namely Ipê and Sombreiro, with respectively 66 and 56 individuals. Based on the areas available for tree planting, it was found that the squares in the city of Rorainópolis have, for the most part, a high deficit of urban afforestation, with poorly distributed and insufficient vegetation cover.
