Diagnóstico da arborização urbana de Almenara-MG

Abstract

Afforestation is fundamental to the well-being and quality of life of urban areas, but some aspects must be considered for all the social and environmental benefits achieved, as the lack of planning negatively affects the quality of life of its residents, especially in urban areas. small cities especially conflict between trees and urban equipment and furniture. Given this, the present work analyzed the floristic composition and the conflicts between the trees and the urban afforestation infrastructure in eight neighborhoods, including nine squares in the city of Almenara-MG. Frequency, origin and location aspects of the city's road network were taxed. Besides, conflicts with the electric network, editing, and traffic of people and vehicles were used. 2038 tree isolates were found in the road network and 221 in the squares. In the streets were found 61 species of 22 families, in which 36 species of 18 botanical families. being 50% native to Brazil. In squares with the most frequent species of Licania (Benth.) Fritsch with 17.19%, and in streets with Azadirachta indicates with 20%. The squares presented aspects of environmental relevance, with a high percentage of vegetation cover (61.95%) and good average density (114 ind / ha). However, there is a low Shannon diversity index (1.79), as well as conflicts such as obstruction of pedestrian crossing through root outcrops, and the identification of health problems. Already the street trees, the most uncomfortable situation for urban mobility were the trees positioned in the wagon bed (56%), 74% of sidewalks with the width less than 1.90 m (recommended), and the average height of first fork below recommended (1.80 m). Besides, 87% of the trees did not have adequate beds; 24% caused outcrop damage, and 48% had some health problems. Only 16% of the tree individuals had conflicts with the electricity grid, justified by the newly implanted trees, yet 9% had conflicts with lampposts. It was verified, therefore, that the Almenara afforestation needs guidance to the population regarding their participation in the management of the trees and the elaboration of an afforestation plan for the municipality. Thus, this diagnosis may help support the review of the city's master plan, as well as the creation of a future urban afforestation management plan in the municipality and warns of other small towns
