Research Highlights

Biomass Pre-Processing by Torrefaction Improves Biofuel Consistency (2018)
FPL-2018-10 Custom-made equipment fabricated for the torrefaction of wood chips now provides the sample quantities needed for application testing and quality control assessments.

Comparing Juvenile Wood Depictions in the Literature to Wood Property Maps for Mature Longleaf Pines (2020)
FPL-2020-97 Juvenile wood in the southern pines is usually shown as a central core of wood surrounded by mature wood, the latter tapering down in thickness when moving from the base of a tree to its crown. The present study addresses the degree to which different juvenile wood depictions presented in the literature are applicable to a sampling of 70-yr-old longleaf pine (Pinus palustris Mill.) trees.

Does Getting Old Change Juvenile Tendencies? Maps Show Wood Variability in Mature Longleaf Pine (2019)
FPL-2019-67 Juvenile wood in pines is usually shown as a central core of wood, varying little by diameter or cambial age, nested within mature wood tapering to the upper portion of the stem. This USDA Forest service study addresses the degree to which different representations of juvenile wood are applicable to a sampling of 70-year-old longleaf pine trees.   

Environmental impacts on tree bark chemistry (2017)
FPL-2017-100 Evidence shows changes in tree bark chemistry from a long-term elevated carbon dioxide treatment have the potential to impact their conversion to biofuels.

Potential Impacts of Climate Change on Tree Bark (2015)
FPL-2015-188 Evidence shows changes in bark chemistry from an elevated carbon dioxide treatment applied to sweetgum trees.
