This study was carried out in medium and late regeneration stage tracts. Medium regeneration stage tract was sub-divided in 4 community classes: Class 1 (DBH > 10 cm); Class 2 (5 < DBH < 10 cm); Class 3 (1 < DBH < 5 cm) and Class 4 (0,1 < height < 1,3 m). In late stage forest, 166 points centered-quarter was plotted to woody individuals sampling (DBH > 10 cm). The floristic and phytosociological parameters of secondary forest were lower than mature forest ones. Futhermore, the low values on richness and abundance of late species in secondary forest demonstrates that some mature forest species have difficult in spreading due to the lack of dispersal species, mainly the big ones, and human impacts on these animals.
