Current Research

  • I am a member of a team that has been assigned the problem of conducting research to develop inventory based estimates of carbon on United States forest lands. My research is focused on aspects of empirical estimats forest carbon principally through the use of current and past forest inventories as well as various ancillary data.
  • Results of this research are intended to address some of the management and policy issues of forest carbon sequestration that are of concern to government policymakers, industrial and nonindustrial landowners, and conservation groups.

Research Interests

Plans for research direction include continuing to develop estimates of forest carbon stock and stock change and investigate the use of various non-parametric regression methods.

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.
