Forest soils store an estimated 40% of the world's terrestrial carbon, but estimates suggest that around 15–30% of that soil carbon is lost when a forest is harvested. Tracking such losses can be tricky: wildfires, insects, disease and past forest management can all affect forest

Forest soils store an estimated 40% of the world's terrestrial carbon, but estimates suggest that around 15–30% of that soil carbon is lost when a forest is harvested. Tracking such losses can be tricky: wildfires, insects, disease and past forest management can all affect forest soil carbon stores, and tree type, climate and harvesting method can all affect how much carbon is lost.
