This publication provides an overview of forest resources in Maryland based on inventories conducted by the U.S. Forest Service, Forest Inventory and Analysis (FIA) program of the Northern Research Station. Information about the national and regional FIA program is available online at http://fia.fs.fed.us. Since 2004, FIA has employed an annual inventory measuring data on a nominal 20 percent of sample plots each year in Maryland. For the 2013 inventory, estimates for current variables such as area, volume, and biomass, are based on 1009 plots sampled from 2009-2013. Change variables such as net growth, removals, and mortality are based on 961 samples collected in 2004-2008 and resampled in 2009-2013. Estimates from earlier annual and periodic inventories are shown for comparison. See Bechtold and Patterson (2005) and O'Connell et al. (2013) for definitions and technical details.
