| Abstract | (Natural regeneration in a remainder of Araucaria Forest, in the Sao Francisco de Paula, National Forest, Rio Grande do Sul, Brazil). The forest ecosystems of the South of Brazil, especially the Araucaria Forest, were intensively explored, leaving for the present days just a few remainders of the State’s original forests. However, the Araucaria Forest still lacks research and the existent studies of natural regeneration are insufficient and they don’t to arrive to necessary conclusions about the dispersion processes, colonization and the other succession stages which characterize the development of that ecosystem. The objective of this work was to evaluate the natural regeneration of the arboreal species in the categories seedling and juvenile, comparing with the adult categoriy. The work was performed in the Sao Francisco de Paula National Forest in an Araucaria Forest which suffered selective cutting of trees in the past. The juvenile category was sampled in 25 sub-parts of 10 x 5m and the seedling category in sub-parts of 5 x 5 m. The individuals with up to 20cm height were classified as seedling, the individuals with height between 21 and 200 cm were considered as juvenile. A total of 44 species were identified, belonging to 37 genus and 23 families, considering the three categories together (seedling, juvenile and adult). In this group, one species was found exclusively in the seedling category, five were present only in the juvenile category, seven in both seedling and juvenile categories, nine in the juvenile and adult categories, seven exclusively in the adult category and fifteen species were present in all three categories. The araucaria presented reduced number of individuals in all of the categories and a low index of total natural regeneration. |
