RESUMO

The transplantation of young individuals occurring under forest canopy as an strategy of planting stock production for ecological restoration is recent in Brazil. Among its most important advantages we highlight the collection of a high number of species (usually not available in nurseries), the elimination of unknown or expensive nurseriesproceedings (seedsamelioration, storage and pre-germinative requirements) and the obtainment of a high number of individuals when compared to the usual seedscollection. Despite these advantages, some restraints must be considered, once this technique should only be applied on specific situations, like those where vegetated areas will be legally deforested. On these cases transplantation may represent a feasible way to make good use of what otherwise would be wasted, representing an interesting possibility of environmental compensation resulting from activities with adverse effects. Considering that those situations are quite common in developing countries, the present study aims to evaluate the transplantation technique as an strategy of planting stock production, improving ecological restoration efforts. For this matter, this dissertation is divided into two chapters. The former is about the technique feasibility - considering its ecological, technical/silvicultural and economic aspects - and the latter about the transplanted seedlingsperformance under two light conditions (sun and shade). In a general way, seedlings and saplingstransplantation is feasible, although further studies are needed to refine the technique and improve the performance of transplanted individuals.
