Abstract
This publication provides an overview of the forest resources in Pennsylvania based upon inventories conducted by the USDA 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 1999, FIA has implemented an annual inventory measuring data on 20 percent of sample plots each year. For the 2013 inventory, estimates for current variables such as area, volume, and biomass are based on 3,015 forested plots inventoried from 2009-2013. Change variables such as net growth, removals, and mortality are based on 2,750 samples collected in 2004-2008 and resampled in 2009-2013. There are additional tables available online (https://www.nrs.fs.usda.gov/fia/data-tools/state-reports/PA/default.asp). See Bechtold and Patterson (2005) and O'Connell et al. (2014) for definitions and technical details.
