Abstract

Growing concerns about unnecessarily destructive selective logging of tropical forests and its impacts on greenhouse gas (GHG) emissions motivated this study on post-logging biomass dynamics over a 16-year period in a control plot and in plots subjected to conventional logging (CL) or reduced-impact logging (RIL) in Paragominas, Para State, Brazil. All trees >25 cm were monitored in 25.4 ha plots of each treatment, each with a subplot of 5.25 ha for trees >10 cm dbh. The commercial timber volumes in felled trees were 38.9 and 37.4 m(3) ha(-1) in the RIL and CL plots, respectively, but the extracted volumes were 38.6 and 29.7 m(3) ha(-1), respectively. Immediately after logging, plots subjected to RIL and CL lost 17% and 26% of their above-ground biomass, respectively. Over the 16 years after logging, the average annual increments in above-ground biomass (recruitment plus residual tree growth minus mortality) were 2.8 Mg ha(-1) year(-1) in the RIL plot but only 0.5 Mg ha(-1) year in the CL plot. By 16 years post-logging, the RIL plot recovered 100% of its original above-ground biomass while the CL plot recovered only 77%; over the same period, biomass in the control plot maintained 96% of its initial stock. These findings reinforce the claim that conversion from CL to RIL would represent an efficient forest-based strategy to mitigate climate change under the REDD+ and would be an important step towards sustainable forest management.
