When we refer to slash burning, what we're talking about are the branches, the tops and broken pieces of wood that stay behind. I would estimate that, depending on the area in which we harvest, it will be between 5% and 25% of the carbon in the above-ground biomass that is not removed from the site. The remainder goes into the harvested wood product sector, and depending on what we produce from it, we must discount the bark. The carbon in the bark is often used as hog fuel or other energy source.
Depending on the product, 40% to 50% ends up in long-lived wood products and the remainder often goes into pulp or bioenergy.
These are all very round numbers, because it really depends by sector.
