Forests of Iowa, 2013

This resource update provides an overview of forest resources in Iowa based on an inventory conducted by the U.S. Forest Service, Forest Inventory and Analysis (FIA) program at the Northern Research Station in cooperation with the Iowa Department of Natural Resources. Estimates are based on field data collected using the FIA annualized sample design and are updated yearly, for the measurement years 2009-2013 with comparisons made to 2004-2008. The current, 2009-2013, sample data consist of 641 field measured plots on forest land, with about 20 percent of plots measured each year. Data used in this publication were accessed from the FIA Database in March 2014. See Bechtold and Patterson (2005) and O’Connell et al. (2013) for definitions and technical details.
