Avaliação quali-quantitativa da arborização em um trecho da rua Tenente Portela – município de Frederico Westphalen/RS

Abstract

Urban afforestation provides many benefits, mainly related to climate stability, air quality, protection of watersheds and maintenance of biodiversity, in addition to influencing the reduction of noise and visual pollution. This work aimed to evaluate qualitatively and quantitatively the tree individuals found on Rua Tenente Portela, in the Municipality of Frederico Westphalen - RS. For the inventory, a spreadsheet was used with variables such as: identification of the species (common and scientific names), size, free area of the trunk and root system, phytosanitary status, presence of physical damage and compatibility. The inventory referred to Tenente Portela street de Frederico Westphalen-RS, in five blocks, totaling approximately 718 m. Were registered 59 trees and 13 different species were identified. As for the origin, there was a predominance of exotic species, the species with the highest relative frequency of extremosa (Lagerstroemia indica) with 66.1% of the individuals sampled. Regarding the size, 98.3% of the plants were adult size. It was also observed that 59.3% of individuals are under the power grid, and another 40.7% do not have wiring interference. As for the free area, only 1 plant has a wide free area, while 26 individuals did not have any available area, harming their ideal development, despite this fact, 88.1% of the sampled individuals have a deep root system without damage, while 11, 9% with deep root system damage. The occurrence of physical damage by pruning, for example, was observed in most trees. It can be seen, therefore, from the data presented that there is no afforestation plan being executed in the city of Frederico Westphalen and it is strongly recommended that this be elaborated, since the correct conservation of urban afforestation positively affects not only the environment, but also the quality of life of the population.
