Estimates from earlier annual and periodic inventories are shown for comparison. See Bechtold and Patterson (2005) and O'Connell et al. (2013) for definitions and technical details. Overview Total land area of North Dakota is 44.1 million acres of which 1.8 percent, or 804,900 acres, are forested (Table 1). The number of live trees on North Dakota's forest land in 2015 was estimated at 353.3 million trees, an increase of about 3.4 percent from 2010. Net volume experienced an increase of about 8.3 percent between 2010 and 2015. Live tree biomass (above ground) is estimated at 19.6 million oven-dry tons. Net growth and removals by harvest of live trees decreased on forest land, while annual mortality increased in 2015.

This inventory of the Black Hills National Forest (BHNF) covers the years 2007-2011 on the South Dakota portion of the forest and 2005 on the Wyoming portion. It reports more than 1.16 million acres of forest land dominated by ponderosa pine. Forest features reported on include volume, biomass, growth, removals, mortality, carbon, snags, and down woody material, along with information on forest economics. This report provides the public with a set of forest statistics that may be used in the Black Hills' land management decisionmaking.

The eighth inventory of Michigan's forests, completed in 2014, describes more than 20.3 million acres of forest land. The data in this report are based on visits to 4,289 forested plots from 2009 to 2014. Timberland accounts for 95 percent of this forest land, and 62 percent is privately owned. The sugar maple/beech/yellow birch forest type accounts for 19 percent of the State's forest land, followed by aspen (12 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 and now totals about 30.2 billion cubic feet (ft 3 ).The associated net growth, harvest removals, and mortality totaled 674, 313, and 303 million ft 3 / year, respectively. In addition to information on forest attributes, this report includes data on forest health, land use change, family forest owners, timber-product outputs, and future forests.
