Abstract
This resource update provides an overview of the forest resources in Ohio 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.1(See footnotes on page 4.) Information about the national and regional FIA program is available online at http://fia.fs.fed.us. Since 2001, FIA has implemented an annual inventory in Ohio. For the 2015 inventory, estimates for current variables such as area, volume, and biomass are based on 4,145 (1,664 forested) plot samples collected from 2009 to 2015. Change variables such as net growth, removals, and mortality are based on 4,160 samples collected from 2005 to 2009 and remeasuredfrom 2009 to 2015. Estimates from earlier annual and periodic inventories are shown for comparison. See Bechtoldand Patterson (2005) and O'Connell et al. (2014) for definitions and technical details.
