Composição florística da vegetação arbórea de um trecho de floresta de galeria do parque estadual do Rola-Moça na região metropolitana de Belo Horizonte, MG, Brasil

Abstract

The study was developed in a gallery forest in the Área de Proteção Especial do Barreiro area in Rola-Moça state Park, Metropolitan Region of Belo Horizonte (MG). The objective was to determine the floristic composition of that forest, important for subsidy in recovery projects. The floristic composition was determinated from phytosociological sample through the method of quadrats, being demarcated 36 quadrats of 10×10m. All the arboreal individuals were included with girth at breast height equal to or greater than 15cm. Were encountered, 97 species, distributed from 79 genera of 43 families. The floristic composition when compared with other gallery forest in the Southeast and Center-west presented low similarity, being the largest similarity verified to the forest of south of Minas state. The floristic richness showed significant differences when related with distance of the stream, being the zone located at 28, 64 and 82m responsible for the largest richness values.
