A preliminary report: does reduced impact logging (RIL) mitigate non-CO₂ greenhouse gas emissions from natural production forests?

抄録

Reduced impact logging (RIL) is a challenge to mitigate detrimental effects of selective logging, which is known to mitigate C losses as timbers and forest degradation. Although it was predicted that RIL can also mitigate non-CO₂ greenhouse gas fluxes through reduced disturbances, the reality has been rarely reported. In the present study, we conducted a preliminary research on N₂O and CH₄ fluxes in a 2-ha plot in each of primary, RIL and conventional logging (CL) forest in Bornean lowland tropical rain forests. The results showed that CL significantly enhanced N₂O emissions, but N₂O emissions from the RIL forest did not differ from those from the primary forest, suggesting that RIL can mitigate N₂O emissions enhanced by CL. On the other hand, CH₄ fluxes were not significantly different among three forest types.
