dc.descriptionABSTRACT – This study aimed at inventorying the natural regeneration of tree species in an Alluvial Araucaria Forest in the “Planalto Sul Catarinense” region, SC, Brazil; evaluating the dissimilarity between its adult and regenerative components; and verifying the natural regeneration floristic sharing among its different fragments. The regenerative component has been sampled and identified within 48 plots and classified according to the following height classes: Class 1, plants with height varying from 15 cm up to 1 m; Class 2, plants with height varying from 1 and 3 m; and Class 3, plants with height higher than 3 m and DBH (diameter at breast height) smaller than 5 cm. The floristic composition of adult individuals in the area and of regenerative individuals from other fragments has been obtained from the database of the Laboratory of Dendrology of CAV/UDESC. The structure of the regeneration was evaluated by phytosociological descriptors. Dissimilarity between the adult and the regenerative components has been determined by Jaccard, Sorensen and Bray-Curtis distances. The regeneration floristic sharing analysis of different areas was conducted by a dendrogram. A total of 818 individuals belonging to 59 species have been sampled, being Allophylus edulis (A.St.-Hil. et al.) Hieron. ex Niederl. the species with the greatest relative importance. Elevated similarity between the regenerative and adult components have been observed (from 0.24 to 0.43), suggesting a low floristic-structural turnover between components. The area under study have shown a greater floristic connection (<40% of dissimilarity) with other spatially close fragments, indicating that altitude and temperature are important ecological factors for its phyto-geographic compartmentalization.
