Abstract
A phytosociological survey of a stretch of the submontane semideciduous forest under regeneration over 70 years, located in Vicosa, Zona da Mata, Minas Gerais, Brazil, was accomplished in a 1 ha area, in which all woody individuals with a branch circumference of 0.15 m at 1.30 m from the soil level were sampled. A total of 1639 individuals were sampled, distributed over 121 different species from 89 genera of 39 angiosperm families. The diversity index (3.73) and equability (0.78) indicated a high heterogeneity for that community. Among the species, Trichilia lepidota, Piptadenia gonoacantha, Siparuna guianensis, Anadenanthera colubrina, Luehea grandiflora and Apuleia leiocarpa were differentiated by their Importance Value. Branch diameter analysis revealed that the community was in a stage of full regeneration with individuals distributed over all diameter classes. The heights of the individuals from all the species revealed the occurrence of several populations constituted of a high number of young individuals, suggesting a good adaptability to the present time environmental conditions. The forest canopy varied in different patches between 14.6 and 22 m of height, exhibiting sometimes a discontinuity. A classification method supported by another ordination indicated species as slope- and plateau-preferring ones.
