This work aimed to characterize the floristic composition and structure of the tree community of areas
in the process of environmental recovery in the municipality of Bocaiuva do Sul, PR. The production
and dissemination of data and information about floristic and phytosociology of forest cover in two areas
with distinct environmental conditions and interventions, is a relevant contribution to understanding the
dynamics in tree structure in areas of environmental recovery. For this, two areas with different degrees of
degradation were selected: Initial Secondary Forest (FSI), area in which there was a clear cut, removal of
the superficial layers of the soil and revegetation with
Mimosa scabrella
Benth; and Advanced Secondary
Forest (FSA), which represents a fragment of Mixed Ombrophilous Forest where there was selective
exploitation of species of commercial interest. Vegetation sampling was carried out in 10 plots of 150 m²
in each area (0.15 ha), where all trees including dead trees with a diameter at breast height (DBH) equal
or greater than 15 cm. In the FSI, 40 species belonging to 24 families were sampled, while in the FSA, 57
species belonging to 27 botanical families were sampled. The results showed that the vegetation structure
in FSA is different from FSI, with lower tree density, higher basal area and floristic diversity.
