Estructura poblacional de Ocotea puberula en un bosque secundario y primario de la selva mixta misionera

The aim of this work was to study the population structure of Ocotea puberula (Nees et Mart.) Nees (Lauraceae), in a secondary and a primary forests Northeast of Misiones in Argentina, at 26º 15 ¢ S and 54º 15¢ W. Two permanent sampling plots of 3 hectares each were installed in the secondary and primary forest, respectively. Each sampling plot was divided into 75 subplots of 20 x 20 m. In each subplot all individuals of Ocotea puberula equal or greater than 20 cm of height were measured. The structure of size and spatial distribution was surveyed. Ocotea puberula was a secondary species, with a high number of individuals of natural regeneration in the secondary forest, and only adult trees in the primary forest. The species presented a clustered pattern of spatial distribution in both forests.
