Forests of Michigan, 2016

This resource update provides an overview of forest resources in Michigan based on inventories conducted by the U.S. Forest Service, Forest Inventory and Analysis (FIA) program of the Northern Research Station. Estimates are based on field data collected using the FIA annualized sample design and are updated yearly. The annual inventory started in 1999. For the 2016 inventory, estimates for current variables such as area, volume, and biomass are based on 6,662 plot samples collected from 2011 to 2016. Change variables, such as net growth, removals, and mortality, are based on 6,076 samples collected in 2006 to 2011 and 2011 to 2016. Estimates from earlier annual and periodic inventories are shown for comparison. See Bechtold and Patterson (2005) and O'Connell et al. (2015) for definitions and technical details.Page 4: information in the Invasive Plant Species section was revised on June 22, 2017.
