The human pressure on the forest resources of the Brazilian Amazon has been causing illegal logging and deforestation, which already consumed 20% of the natural forests in the region. The necessity of an increasing sustainable usage of the forest resources demanded the development of a polycyclic silvicultural system (PSS) adapted to the dense forests commonly found in the Brazilian Amazon. This PSS is now applied in most of the management plans implemented in the Brazilian Amazon. In this system, harvestings operations are carried out through the environmental-friendly techniques of reduced-impact logging (RIL). Nevertheless, the managed forests in the Brazilian Amazon, as well as in several other tropical forests, are not regenerating the harvested commercial species for future cutting cycles. This means that, yields expected for future cutting cycles will not be the same as those currently observed in the first cycle. The problem of insufficient natural regeneration that undermines sustainable future cutting cycles can be solved through silviculture intensification with the application of post-harvesting silvicultural treatments. These treatments consist in using enrichment planting and tending in logging gaps over seedlings and saplings as well. The authors then, present the concepts of assisted densification and organized disturbance and their potential application to ensure the regeneration of commercial species. Consequently, this can improve future harvestings as well as the conservation of rare and threatened species in the Amazon and in the other tropical forests worldwide.
