Estimates are based on field data collected using the FIA annualized sample design and are updated yearly. Information about the FIA program is available at http://fia.fs.fed.us. For the 2015 inventory, estimates for current variables such as area, volume, and biomass are based on 5,996 plot samples collected from 2010-2015. Change variables such as net growth, removals, and mortality are based on 5,922 plots collected in 2005-2010 and remeasured in 2010-2015. See Bechtold and Patterson (2005) and O'Connell et al.
