Forestry residues are the limbs, tops, and other materials left on the forest floor after a conventional logging operation has cleared a managed forest – typically for the paper and lumber industries.  Forestry residues are often bulldozed into a pile and then burned in the field, but they offer one of the largest sources of unused biomass in the state, and can potentially be used for biofuels production.
