Reduced-impact logging

In the eastern Amazon, 24.5 ha of reduced-impact logging (RIL) combing with pre-harvest liana cutting - performed 2 years before logging -, 24.5 ha of conventional logging (CL) and 24.5 ha of unlogged forest were sampled with plots of 200 m² (n = 21 per treatment) 30 years after first cutting cycle. We found that liana densities (>1 cm DBH), basal areas, above-ground biomass, and the proportions of liana-infested trees in RIL plots were, respectively, 53%,54%, and 48% lower than CL plots– both harvesting at similar intensity. Based on drone-LiDAR data, trees in RIL plots averaged 19% taller and canopy rugosity was 33% lower with 75% fewer gaps than in CL plots. Samples in unlogged plots revealed to be equal from RIL plots in liana densities, basal area, above-ground biomass, gap fractions, and tree heights, but lower in canopy rugosity, liana basal area, and proportions of liana-infested trees. These results highlight the long-term benefits of pre-harvest liana cutting, which should be adopted along with other RIL practices to increase the sustainability of tropical forest management.
