The aim of this study was to determine changes in composition, abundance and richness of species along a
forest gradient with varying soils and flood regimes. The forests are located on the left bank of the lower Jucu
River, in Jacarenema Natural Municipal Park, Espírito Santo. A survey of shrub/tree species was done in 80
plots, 5x25 m, equally distributed among the forests studied. We included in the sample all individuals with
≥3.2 cm diameter at breast height (1.30 m). Soil samples were collected from the surface layer (0-10 cm)
in each plot for chemical and physical analysis. The results indicate that a significant pedological gradient
occurs, which is influenced by varying seasonal groundwater levels. Restinga forest formations showed
significant differences in species richness, except for Non-flooded Forest and Non-flooded Forest Transition.
The Canonical Correlation Analysis (CCA) showed that some species are distributed along the gradient under
the combined influence of drainage, nutrient concentration and physical characteristics of the soil. Regarding
the variables tested, flooding seems to be a more limiting factor for the establishment of plant species in
Restinga forests than basic soil fertility attributes.
