Resumo: | Due to the phytophysiognomic heterogeneity of the northern Minas Gerais region, the structure and richness of local vegetation remnants vary considerably, and regardless of the fact that the region is yet little known, it has been widely explored economically. The objective of this study is to characterize the structure and floristics of a fragment of Arboreous Caatinga located in Juvenília, Minas Gerais. Twenty 20 × 20m plots (400 m2) were allocated, to a total of 0.8 ha, and all individuals in them with a CAP (circumference at breast height) ≥ 10 cm were recorded. To complement the floristic listing of shrub and tree components, four visits were undertaken to collect botanical material, between January and December 2003. The floristic composition was represented by 64 arboreous species, out of which 47 were sampled in the phytosociological survey. The local diversity was H’ = 2.90 and J’ = 0.76, with a dominance of species Anadenanthera colubrina, Poincianella pluviosa and Myracrodruon urundeuva, respectively with Dominance: 26.3%, 13.1% and 20.3%; Density: 11.2%, 16.6% and 10.1%; Frequency: 6.2%, 6.5% and 5.5% and Importance Value: 14.6%, 12.1% and 12.0%. The diameter distribution of the community tended to normality, with less individuals in smaller and larger diameter classes. The structural and floristic patterns of the community in question were found to be similar to other reasonably preserved remnants of deciduous forest, inside and outside the Caatinga biome, despite the evidence of local anthropic intervention. |
