This paper aimed at understanding the behavior of the arboreal species of Mata da pedreira situated at Estação Experimental Mata do Paraíso of the Departamento de Engenharia Florestal, Viçosa-MG-, by studying their phytossociological structure and their sucessional classification. The area has 40 ha and the sampled area was of 1 ha, whee were implanted 40 plots with 250 m2 (25,0 X 10,0 m) distributed, at the toposequences proporcionally to the area of each one. The level of inclusion was of CAP 15,0 cm, the sucessional classification the species were observed on field, besides the using of bibliography connected to the subject. In phytosociology 1400 individuals belonging to 48 families, 109 genery and 146 species were analized. The species brought up a level of diversity of Shannon-Wiener (H ) of 4.25 nats/species and equability of Pielou (J´) of 0,83. These levels of diversity are among the highest ones encountered in Minas Gerais state. In terms of sucessional classification, the area studied is a secondary forest formation, showing itself in a sucessing initial stage, where there has been a high presence of species classified as initial secondary, followed by late secondary and pioneer tree species.
