“…This method is conditioned to the values of the remaining basal area, the maximum intended diameter, the number of individuals per class of diameter per hectare and the choice of species to be harvested [29]. Associated with the balanced distribution model, the application of post-harvest silvicultural treatments, such as conduction of regeneration, thinning and enrichment planting, has been an alternative to recover the forest structure as well as the populations of species of interest [11,12,[30][31][32][33][34][35].…”

The existence of degraded forests is common in the Eastern Amazon. The maintenance of these forests standing and the recovery of their productivity play an important role in the conservation of biodiversity, storage and carbon sequestration. However, the management techniques currently employed are designed for natural forests in the first harvest cycle or lightly explored and do not apply adequately to forests that have gone through several harvest cycles. Therefore, adaptations and the establishment of new management criteria that take into account other characteristics of these types of forests are necessary to ensure their sustainability. The objective of this study was to propose a silvicultural management system that has the potential to recover and perpetuate the productivity of an intensively logged tropical forest. A forest census was carried out on 535.6 ha for trees with dbh ≥ 25 cm. With these data, the following two treatments were designed: (1) criteria: the BDq method was applied from B = 9.8 m2 ha−1, D = 100 cm and q = 2. The criteria for standing wood commercialization were, in this order, first, Health; second, Tree Stem; third, Tree Density and fourth, dbh ≥ 105 cm. (2) Control: the planning was in accordance with Brazilian regulations. For the cost–benefit and sensitivity analysis, the Net Present Value (NPV) was used and a projection of ±20% was made in the commercial price of standing wood. In the criteria treatment, a higher number of trees and species destined for the commercialization of standing wood was verified in relation to the control treatment, showing a greater diversity of species. In the criteria treatment, NPV was positive and superior to the control treatment in all scenarios. The proposed silvicultural management system with an object of an explored and enriched forest, with criteria for harvesting trees with a minimum cut diameter of 25 cm, proved to be viable to generate economic returns and with conservationist potential for the continuous supply of forest products and maintaining biodiversity.

O objetivo deste trabalho foi descrever os caracteres morfológicos de frutos e sementes de Lecythis lurida (Miers) S.A. Mori. Os frutos foram coletados no munícipio de Laje – Bahia em abril de 2018. No estudo do fruto, foram observadas as características: tipo, dimensões, textura, consistência do pericarpo e número de sementes por fruto. Os aspectos observados para as sementes foram: externas - cor, forma, dimensões, textura e consistência do tegumento; internas - embrião (cotilédones, eixo hipocótilo-radícula). O fruto de inhaíba é do tipo pixídio, indeiscente, de textura lenhosa, apresentando em média quatro sementes por fruto, com comprimento médio de5,61 cm e largura média de7,48 cm. As sementes apresentam formato triangular anguloso, tegumento ósseo, dotadas de arilo carnoso na região basal e ápice umbonado, com dimensões médias de 43,55 x 36,89 x29,28 mm. O embrião é conferruminado, sem distinção de cotilédones, eixo hipocótilo-radícula e plúmula. A morfologia de frutos e sementes fornece subsídios que contribuem para o reconhecimento da espécie.
