Inventário da arborização viária do bairro São Francisco Xavier na cidade de Dois Vizinhos - PR

Abstract

The urban forest inventory is the main tool to know the afforestation of a city, allowing to evaluate important planning aspects, based on management techniques, ecological enrichment and guarantees of quality of life indices. The present work had as objective to make the inventory of the afforestation of the neighborhood of São Francisco Xavier, Dois Vizinhos - PR, as a tool for the planning of the neighborhood afforestation, assisting in the practices of management and monitoring of the afforestation. The neighborhood has 2000 inhabitants, the approach used for the study was by census raising qualitative and quantitative characteristics. The data collected were: Tree location; Tree characteristics and conditions of the urban environment and management. With this information we calculated the Tree Coverage Index (ICA), Plant Coverage Index (ICV). It was raised 1099 individuals from 43 families, belonging to 69 genera and 82 species. 53.52% of the species are exotic, 22.53% are invasive exotic, 6.48% toxic exotic, 0.55% toxic invasive exotic and 16.92% native. Seventycomma thirty-three percent of the trees has a canopy area below 5.51m2. The Vegetable Coverage Index for the neighborhood is 1.39% and the Arboreal Coverage Index is 7.28%. Barro São Francisco Xavier afforestation has characteristics of inadequate management and degradation of arid individuals that make up the vegetation of the roads. Much of the benefits that afforestation can promote are not enjoyed by the population. 50% of the trees need to be replaced due to the degradation of the structure of the individual, which can cause accidents to vehicles and pedestrians that walk the neighborhood roads.
