Woody biomass usually refers to any wood that can be used to produce energy. Buyers typically pay less for woody biomass than for veneer, sawtimber, and pulpwood; therefore, biomass usually is produced from small-diameter trees, branches, dead trees, downed logs, brush, and stumps. Woody biomass harvesting has the potential to expand forest management options by offering a market for low value trees and materials that interfere with the growth of better trees or that contribute to a fire hazard. Biomass harvesting guidelines have been or are being developed in each of the Lake States to ensure that biomass harvests help promote sustainable forest management. Biomass is commonly bought and sold on a tons-per-acre basis.
