The seventh inventory of Michigan's forests, completed in 2009, describes more than 19.9 million acres of forest land. The data in this report are based on visits to 7,516 forested plots from 2005 to 2009. Timberland accounts for 97 percent of this forest land, and 62 percent is privately owned. The sugar maple/beech/yellow birch forest type accounts for 18 percent of the State's forest land, followed by aspen (13 percent) and white oak/red oak/hickory (7 percent). Balsam fir, red maple, and sugar maple are the three most common species by number of trees. Growing-stock volume on timberland has continued to increase totaling about 28.7 billion cubic feet (ft3). The associated net growth, harvest removals, and mortality totaled 698, 311, and 272 million ft3/year, respectively. In addition to information on forest attributes, this report includes data on forest health, biomass, land-use change, and timber-product outputs. Detailed information on forest inventory methods, data quality estimates, and important resource statistics can be found in Statistics, Methods, and Quality Assurance on the DVD in the back of this publication.
