We have developed a phytosociological survey on tree stratum (woody overstory) from a nine-year-old reforestation at a Private Reserve of Natural Heritage, São Paulo State, Brazil. We evaluated all the specimens from the tree stratum (Circumference at Breast Height (CBH) ≥ 15 cm). They were obtained from 20 subplots (12.5 × 18 m), located at 20 permanent plots. We evaluated 364 specimens from the tree stratum and found 76 species, 63 genera, and 24 families at a 0.45 ha area. The canopy height ranged from 5 to 11 m. The estimated basal area was 18.29 m² ha-1, and the pioneer species contributed with 69.2 percent of the total plant species. Both basal area and average height parameters increased throughout time, whereas the diversity did not. The diversity index was considered high for a reforestation.
