Timber residue supply for bioenergy in the northern tier of the Great Lakes : determinants and availability

"Timber residues, a timber byproduct, are a low-cost source of biomass that avoids the environmental and food market consequences of other energy feedstocks. We studied the effect that price, forest species mix, bio-energy attitudes, environmental amenities, and environmental disamenities have on the decision to harvest for non-industrial private forest owners (NIPFs) in northern Michigan and Wisconsin."--from abstract.
