RESUMO

ABSTRACT In order to describe the population structure of Myrocarpus frondosus Allemão, the structure of size class and the spatial distribution of the individuals species was studied, in a riparian area of the Paranaense Forest in Misiones, Argentina, at 27º39’00” S and 55º44’30” W. The species was studied in circular plots. All the individuals of Myrocarpus frondosus with diameter greater or equal to 10 cm (at 1.3 m height - DBH) were considered for the tree stage, and all seedlings with diameter ranging from 2 cm to 9.9 cm were considered for natural regeneration. Three hundred and ninety six individuals were found (431 ind. ha-1), with 180 individuals in the tree stage and 216 individuals in the natural regeneration stage. The results show that the diameter size of the population varied from 2 cm to 50 cm with reverse J distribution, representing a substantial recruitment in the younger age classes. The species presented a clustered pattern of spatial distribution.
