Abstract

This project aims to generate monitoring information on the remnant forest dynamics and regeneration in long-term managed forests (27 years) in the eastern Amazon for timber production. For this we will (i) monitor 73.5 ha of managed remnant forests, with 3 areas of 24.5 ha in each of the applied treatments (reduced impact logging (EIR), conventional logging (EC) and unlogged forest - control (FT)). In each remaining 24.5 ha (350 m x 700 m) forest area, 49 plots of 0.5 ha (50 m x 100 m) are established. In each of these treatments will be calculated the Annual Periodic Increment (IPA) in DBH, volume and basal area, and the Annual Current Increments (ICAs) in DBH and volume from 1993 to 2020. Mortality and recruitment will also be calculated in each treatment. as well as the total and annual timber stock; (ii) to evaluate regeneration of species of commercial timber value in areas 25 years after harvesting wood by establishing 20 plots in each of the three treatments; (iiii) we will monitor enrichment plantings of two high value species, mahogany (Swietenia macrophylla King) and ipe-yellow (Handroanthus serratifolius (Vahl) S.Grose), in 18 and 10 clearings of varying sizes; we will monitor enrichment plantations in kipoalic areas with species of high commercial value, promoting the potentialization of production forests.. With the scientific results of this research project it is expected to contribute to the understanding of the dynamics of remaining tropical forests, the regeneration of commercial species and the enrichment planting. This information is rare in the forest sciences and is substantially important information for predicting the future of these managed forests and the role of native forest management in the development and conservation of the Amazon.
