This publication provides an overview of forest resource attributes for Illinois based on an annual inventory conducted by the Forest Inventory and Analysis (FIA) program of the Northern Research Station (NRS) of the U.S. Forest Service. These estimates, along with web-posted core tables, are updated annually. In 2014, NRS-FIA changed from a 5- to a 7-year inventory cycle, wherein 1/7th or 14.3 percent of plots will be measured annually until completion. To ensure that all plots are transitioned to the new cycle length, estimates reported for 2014 include data collected from 2009-2014, with comparisons made to data reported in 2009 (and collected from 2005-2009).
