Qualidade na implantação da arborização urbana nos novos loteamentos da cidade de Pato Branco Paraná

Abstract

Through the emergence and growth of cities, green areas are gaining importance, as the artificiality conditions of urban centers in relation to natural areas have caused various damages to the quality of life of its inhabitants. The heterogeneity of species, besides being a way of protecting, diffusing and valuing the Brazilian flora, favors the survival of animals, which are important elements of the ecological balance. In this way, much of what has been wrong in the planning of urban afforestation, is to know the species and not the environment. The work was carried out in the city of Pato Branco, Southwest of Paraná, where the objects of study were the Residential Lotissement, Dom Carlos, Industrial 2 and the Residential Lotissement Parzianello 1. In this way the quality of the implantation of the urban afforestation in these new allotments was evaluated. The evolution of afforestation as a function of time. Law No. 3.969, of December 20, 2012, which establishes the Plan of Urban Arborization of the Municipality of Pato Branco - PMAU, served as an instrument to evaluate its compliance. It was possible to verify several problems related to the implantation of afforestation in Residential Lotissement, among them, the lack of a standard of the implanted seedlings, with total height less than 2,20 m and height of first bifurcation less than 1,80 m, lack of maintenance, conduction and pruning of these seedlings. In the Residential Lotissement Indistrial 2 it was possible to account for 116.06% of established seedlings in relation to the initial project, already in the Residential Lotissement Parzianello 1, only 23.65% and in the Residential Lotissement Dom Carlos only 19.95%. The tutorship of the plants was another item that left something to be desired in the Residential Lotissement Dom Carlos and Parzianello 1, unlike Residential Lotissement Industrial 2, in which it presented 100% of the plants with the presence of the tutor playing its role. In terms of accessibility, the width of the roads was respected, however, the presence of access ramps at the corners of the road did not meet the standards of construction, which did not meet the standards of ABNT 9050. Although we observe a certain evolution in the patterns of afforestation between Residential Lotissement, we can conclude that there is a lot to evolve, besides the need to implant seedlings that meet the required standards.
