Abstract:—The Reserva Biológica Estadual da Praia do Sul (Ilha Grande, RJ) is an important remaining of Restinga habitat in the Rio de Janeiro State. The Restinga vegetation is not homogeneous and it is distributed in different vegetation zones, each zone having different topography, physiognomy and floristic. We studied the bromeliad community analyzing some ecological parameters such as richness, abundance, density, biomass and variation in species composition in four vegetation zones. We sampled 150 plots of 100 m2 (10×10 m), distributed in the four vegetation zones, recording the bromeliad species and their abundance, and measuring the height, DAP, and density of the trees. We tested the differences in ramets abundance and vegetation complexity between the four vegetation zones with ANOVA followed by Tuckey’s test. We found a total of 16 bromeliad species, with different abundances and distribution patterns among the four vegetation zones, and with significant differences in abundance among species. The data indicates that the high species richness found in the RBEPS can be related to the local heterogeneity and complexity. The differences found among vegetation zones seem to be related to the vegetation structure of each zone.
