What Do Forest Carbon "Sequestration" and "Storage" Mean?
Carbon storage is the building of plant structures (woody biomass) by converting glucose into cellulose, and lignin. Most carbon in a forest is stored in the soils and the above-ground living biomass (e.g., trees and other plants). Roughly 50% of the dry mass of a tree is carbon, much of which is stored in the wood fibers.
