Short summary

The effect of clear-felling on soil greenhouse gas (GHG) fluxes was assessed in a Sitka spruce forest. Measurements over 4 years showed that CO₂, CH₄, and N₂O fluxes responded differently to clear-felling due to significant changes in soil biotic and abiotic factors and showed large variations between years. Over 3 years since felling, the soil GHG flux was reduced by 45% due to a much larger reduction in CO₂ efflux than increases in N₂O (up to 20%) and CH₄ (changed from sink to source) fluxes.
