    Description

    The 2007 Energy Security and Independence Act (ESIA) requires 16 billion gallons of ethanol to be produced from lignocellulose biomass by 2022 in the United States. Forests can be a key source of renewable lignocellulose for ethanol production if cost and conversion efficiency barriers can be overcome. We explored opportunities for using woody biomass from thinning western conifers as source materials for conversion to biofuel. We present preliminary results using suppressed lodgepole (Pinus contorta Douglas ex Louden var. latifolia Engelm. ex S. Watson) and ponderosa pine (Pinus ponderosa C. Lawson var. ponderosa) from Pringle Falls Experimental Forest in central Oregon. We first examined growth rates of suppressed and presumably unsuppressed lodgepole pine and ponderosa pine planned for removal during thinning operations, and determined that all sampled trees were equally suppressed. We found component polysaccharides in relatively high concentrations among all sample trees.
