摘要: Abstract Growing concerns about unnecessarily destructive selective logging of tropical forests and its impacts on greenhouse gas (GHG) emissions motivated this study post-logging biomass dynamics over a 16-year period in control plot plots subjected to conventional (CL) or reduced-impact (RIL) Paragominas, Para State, Brazil. All trees >25 cm were monitored 25.4 ha each treatment, with subplot 5.25 ha for >10 cm dbh. The commercial timber volumes felled 38.9 37.4 m3 ha−1 the RIL CL plots, respectively, but extracted 38.6 29.7 m3 ha−1, respectively. Immediately after logging, lost 17% 26% their above-ground biomass, Over 16 years average annual increments (recruitment plus residual tree growth minus mortality) 2.8 Mg ha−1 year−1 only 0.5 Mg ha−1 year−1 plot. By post-logging, recovered 100% original while 77%; same period, maintained 96% initial stock. These findings reinforce claim that conversion from would represent an efficient forest-based strategy mitigate climate change under REDD+ be important step towards sustainable forest management.
