Resumo. This study indicated the non-timber forest products (NTFPs) associated with tree species of the remnants of Tropical Rain Forest studied in southern Santa Catarina. The species examined were ranked according to their potential value for sustainable exploitation (PVSE) of NTFP, applying the following information obtained from literature review: density, parts used, capacity for natural regeneration and growth, knowledge about reproductive biology and population dynamic, required processing and level of injury or toxicity. The results show possible conservation and regional development, from alternative sustainable use of forest resources. Of the 79 species observed, 38 reached PVSE equal or higher than 10, being considered of high potential for sustainable exploitation of NTFP.
