Arborização urbana em Jequitaí - MG: atributos funcionais e diversidade

Abstract

The objective of this study was to characterize the urban afforestation in relation to diversity, ecology and interaction with the environment, throughout an inventory of all the squares (seven) and avenues (four) of the city of Jequitaí, in Minas Gerais. It was carried out a survey of all the individuals with circumference at 1.30m of the soil, greater or equal to 15 cm, including trees and palm trees. The group of pollinators was defined by the pollination syndromes and to determine the dispersal agent itwas used the dispersal syndromes. We evaluated 111 individuals, distributed in 16 families, 23 genera and 24 species. Regarding the origin of the species, 37% are native (8% from other regions of Brazil, 29% are native to the region) and 63% are exotic. Melittophily constitutes the more frequent pollination syndrome among the analyzed species, whereas zoochory was the most frequent dispersal mode. The afforestation of the city of Jequita is constituted mostly by exotic species. The afforestation has low diversity, with Licania tomentosabeing the most frequent species. The native species of the region such as Cordia glabrata, Hymenaea courbariland Genipa americana, stand out for interacting with the fauna and receiving a good state of conservation.
