| Resumo | |
Innovative reforestation approaches integrating native timber production could deliver both economic and ecological benefits. However, the economic viability and silvicultural performance of these species under reforestation conditions remain poorly understood. This study assessed the silvicultural performance and economic viability of three valuable commercial Brazilian native species (Peltophorum dubium (Spreng.) Taub., Hymenaea courbaril L., and Handroanthus impetiginosus (Mart. ex DC.) Mattos) for timber production in a 20-year-old reforestation plantation. We coupled tree-ring analysis with growth modeling, and economic evaluation to estimate timber yields, define harvest cycles, and assess economic viability under different scenarios. P. dubium reached commercial harvest age at 27 years, followed by H. courbaril (37 years) and H. impetiginosus (43 years). Stand-level simulations yielded timber volumes of 105 m3 ha(-1), 213.3 m3 ha(-1), and 201.5 m3 ha(-1) for H. impetiginosus, H. courbaril, and P. dubium, respectively. Timber revenues were sufficient to offset costs, compensating for 103.8 % of total investment. Sensitivity analysis revealed that profitability is highly dependent on discount rates and timber market prices fluctuations. Even with pessimistic scenarios considering declines in timber prices and rising costs, the model remained feasible at 8-9 % discount rates (USD 27,66.4 ha(-1) and USD 1220.5 ha(-1)), fully offsetting costs and generating income. Our study demonstrates that integrating native silviculture into reforestation plantations is a promising and economically viable strategy for tropical forest restoration. These insights hold significant strategic value for scaling up reforestation initiatives to meet ambitious restoration commitments, while foster new forest-based economies. (AU) | |
