Abstract
This update provides an overview of forest resources in Illinois following an inventory by the USDA Forest Service, Forest Inventory and Analysis program, Northern Research Station. Estimates are derived from field data collected using an annualized sample design. Current variable estimates such as area and volume are based on 5,994 (1,046 forested) plots measured in 2011–2017. Change variables such as net growth, removals, and mortality are based on 5,914 (964 forested) plots measured in 2005–2011 and resampled in 2011–2017. See Bechtold and Patterson (2005), O'Connell et al. (2014), Gormanson et al. (2017) for more details.
