Advances in BioEnergy

New Ways to Operate

Two of the main factors that influence harvesting costs are the method used and tract size. Conventional forest harvesting operations are more costly as tract sizes fall below 10 hectares, due, in part, to the high cost of moving, loading, and relocating large mechanized equipment designed for large tracts of industrial forest.

The wildland-urban interface (WUI) in the Southern United States contains a variety of woody biomass sources that could be used for bioenergy.

Wildland-Urban InterfaceThe WUI is defined as the area where human development is interspersed with undeveloped wildlands. In the South, many woods (biomass sources) are fragmented by commercial and residential development and composed primarily of private forest lands.

Land in the WUI is often fragmented and noncontiguous, requiring harvest methods appropriate for smaller stands. As demand for harvesting systems within the WUI increases, new systems are being developed that employ machines with multiple functions that are better suited to small operations.
