Abstract

Tree crowns, unmerchantable tops, stumps, and roots form a huge reserve of renewable raw material. Compared with merchantable stems, some 50% additional biomass is potentially available from these unutilized tree components in silviculturally managed forests and, if undersized trees and defected stem parts are included, a considerably higher percentage in overmature, unmanaged forests.
