Sustainability of timber harvesting is increasingly becoming an important issue in the Brazilian Amazon. Reduced Impact Logging (RIL) has been widely promoted as logging techniques that can help achieving sustainable forest management. RIL is a set of techniques aimed to reduce environmental impacts and damage to the standing forest. However, logging gaps created by RIL may not guarantee enough regeneration of high-value commercial tree species for the third and fourth cutting cycles. A possible solution for ameliorating regeneration and maintaining long-term economic value of forests is the application of silvicultural treatments, such as enrichment planting and tending the natural regeneration. However, enrichment planting and tending applied in logging gaps require a significant amount of investments. In this study it was compared the profitability of different postharvesting silvicultural treatments applied in logging gaps at the forest management area of Orsa Florestal S/A, in the Jari Valley, eastern Brazilian Amazon. Untended natural regeneration (control) was compared with two enrichment planting experiments and a tended natural regeneration. Net Present Value (NPV), Land Expectation Value (LEV), Benefit/Cost Ratio (BCR), and Internal Rate of Return (IRR) were applied for determining the profitability of the different treatments. Sensitivity analysis was also performed to determine how changes in parameters would affect the profitability of the treatments. |
