The dynamics of floristic and fitossociology composition in the restoration process were studied on areas within the Rio Turvo State Park, in Cajati, State of São Paulo (77°89ʹ42ʺ N and 72°49ʹ22ʺ W), in a restoration area over three years, on an abandoned banana plantation (Rest 3) and in a  restoration area over five years, on a degraded area of grazing land (Rest 5). In each area, six plots were installed (100 m2 each). We analysed the diameter and height of all individuals over 50 cm of height and we collected soil samples for fertility analysis (0 - 20 cm depth). The structure of the community was described based on phytosociological estimators (relative density, relative dominance, importance value). Diversity was calculated using Shannon’s diversity index, and evenness by Pielou’s index. There were 2,117 ind ha-1 (18 families and 39 species) in Rest 5 and 4,650 ind ha-1 (21 families and 54 species) in Rest 3. The phytosociological parameters reflect areas in the initial stages of secondary succession, where previous use as a banana plantation incurred in the composition of a more favorable environment for the development of planted species and establishment of propagules.
