Results of the combined 1999, 2000, 2001, and 2002 annual forest inventories of Minesota show that 16.3 million acres or 32 percent of the total land area is forested. The estimate of total all live tree volume on forest land is 17.6 billion cubic feet or approximately 1,080 cubic feet per acre. Just over 15.0 million acres of forest land in Minnesota is classified as timberland (forest land that is not reserved and is of high productivity). The estimate of growing-stock volume on timberland is 15.4 billion cubic feet or approximately 1,024 cubic feet per acre. all live aboveground tree biomass on timberland is estimated at 435 million dry tons or approximately 29.0 tons per acre. Important pest in Minnesota forests include the forest tent caterpillar and spruce budworm
