- Abstract
This study aimed to evaluate the natural shrub-tree regeneration in abandoned pasture versus forest fragment, and its floristic similarity in the Forno Grande State Park. Twenty plots of 20 x 2.5m (10 per environment) were randomly allocated 100m from the border. She analyzed individuals with height ≥ 50cm and diameter of chest height ≤ 2.5cm. Density, Frequency, Dominance, Import Value Index, Shannon Index and Pielou equability were determined. Subsequently the data was organized in an array of species abundance and submitted to the analysis of distended correspondence. The pasture presented a greater number of individuals than the forest fragment, but with less diversity. There is a predominance of Asteraceae (89.77%) in the pasture and the Rubiaceae (21.14%), Piperaceae (17.89%) and Monimiaceae (13.82%) in the fragment. The areas do not present the same regeneration pattern, as evidenced by the eigenvalues X (0.82) and Y (0.42). The abandoned pasture presented a larger number of individuals and less diversity than the forest fragment, and it is recommended to adopt enrichment techniques to optimize the increase of local diversity.
