Wisconsin's forest resources in 2002.

Results of the 2002 annual inventory of Wisconsin show about 16.0 million acres of forest land, over 22.2 billion cubic feet of live volume on forest land, and nearly 598 million dry tons of all live aboveground tree biomass on timberland. Gypsy moth, forest tent caterpillar, twolined chestnut borer, bronze birch borer, ash yellows, and white pine blister rust were among the pests of Wisconsin forests.
