Arborização urbana no município de Pérola D'Oeste/PR

Abstract

The present study aimed to identify the taxonomic composition of the trees used in the urban afforestation of Pérola D'Oeste, estimating the number of arboreal individuals and determining the percentage of native and exotic species. Urban afforestation was analyzed qualitatively and quantitatively, and sampling was restricted to specimens with a diameter at breast height at 1.30 m from the ground (DBH) > 5 cm. During the period from July to December 2021, the specimens were collected, photographed and deposited in the Herbarium of the Universidade Federal da Fronteira Sul Campus Realeza (Herbarium REAL) for identification and analysis. We recorded 474 arboreal individuals, belonging to 65 species, and 30 families, with Mangifera indica L. the most frequent species with 23.20% of the individuals. Exotic species predominated in the city's afforestation, representing 73.15% of the total number of individuals sampled. The Shannon Diversity Index (H ́) was 3.20 demonstrating high diversity.
