Current Research

I am a Forester in the Northern Research Station's Forest Inventory and Analysis (FIA) program. My primary responsibilities involve providing data analysis and research assistance to the forest carbon estimation and reporting group. This program is responsible for reporting on greenhouse gas (GHG) emissions and removals in the forest land category as part of the United States' commitment to the United Nations Framework Convention on Climate Change.

National Research Highlights

Distribution of (A) understocked timberland by ownership in the CONUS, (B) tree density by ownership and all live stocking on timberland in the CONUS (number of trees), (C)  aboveground live tree CO2 density (t ha-1) and mean annual net CO2 flux (t ha-1 yr-1) by ownership and all live tree stocking in the CONUS, and (D) reforestation area and CO2 sequestration potential – based on current tree planting capacity in the US – when increasing stocking on timberland from non-stocked to poorly stocked, medium stocked, or fully stocked in the CONUS. Error bars represent the 95% confidence intervals. Negative estimates indicate net C uptake (i.e., a net removal of C from the atmosphere).

Potential to Increase Carbon Sequestration with Tree Planting

Year: 2020

Almost one-third of Earth’s total land area is comprised of forest, which is also the largest terrestrial carbon sink. A Northern Research Station scientist and his partners have established that fully stocking the Nation’s understocked forests could increase carbon sequestration by about 20 percent.

Better Estimates of Carbon Inventory in Dead Wood Now Available

Year: 2013

Researchers with the Forest Inventory and Analysis (FIA) program have sampled downed and dead woody material (DWM) since 2002 so most U.S. states now have a complete cycle of DWM data. As a result, for the first time, researchers used field measurements to obtain estimates of DWM biomass and carbon stocks for the FIA program's report and for DWM carbon estimates in the National Greenhouse Gas Inventory report.
