Phytosociology of the arboreal component of a patch of Mixed Ombrophilous Montane Forest at Curitiba, Paraná State, Brazil.

Abstract

A phytosociological study on the tree, species of the Mixed Ombrophilous Montane Forest at Barigüi Park, Municipality of Curitiba, Paraná State, Brazil, was carried out. The sampling method used was the point-centered quarter method. The criterion of inclusion adopted was: trees with PBH between 10 and 29 cm for the lower size stratum, and equal or above 30 cm for the higher size stratum. In total, 150 centered points were established. In the first group (the lower one) were found 77 species and 34 families, and in the second group 67 species and 32 families. In both groups, the richest families were Myrtaceae (17 species) and Lauraceae (eight). The highest diversity was found in the group with smaller size due to species association of both strata (species exclusive from the lower stratum and species from the higher stratum represented by young individuals).
