Research Highlights
Quantifying and Managing Carbon Sequestration in Longleaf Pine Ccosystems.
Year: 2014
Forests can offset greenhouse gas emissions by sequestering carbon dioxide in tree biomass, understory vegetation, forest floor litter, detritus, soils and wood products. In partnership with Auburn University and the University of Florida, Forest Service scientists are assessing soil carbon pools an...
