Nonindustrial private forest (NIPF) landowners’ willingness to harvest woody biomass for wood-based bioenergy is important if sustainable feedstock supplies are to be realized in the U.S. However, a significant number of them do not know that unused logging residues could be used to produce wood-based bioenergy. Therefore, this study analyzed landowner willingness to harvest woody biomass in Mississippi contingent upon their knowledge of wood-based bioenergy. The requisite data were analyzed in accordance with the Heckman approach. Results indicated that elderly, male, and resident landowners, having larger tracts of pine plantations were more likely to be aware of wood-based bioenergy. The results further revealed the need for bioenergy related extension education focusing on female landowners and those having small tracts of forest land.
