Results of the annual forest inventory of Michigan show an estimated 19.4 million acres of forest land in the State. The estimate of total all live tree volume on forest land is 29.8 billion cubic feet. Nearly 19 million acres of forest land in Michigan is classified as timberland. The estimagte of growing-stock volume on timberland is 27.2 billion cubic feet. All live aboveground tree biomass on timberland is estimated at 758 million dry tons. Michigan faces several major forest health concerns. Recently introduced exotic organisms are a serious health threat to Michigan''s native forest ecosystems. Other forest health concerns are gypsy moth infestations, oak wilt, and damage caused by the forest tent caterpillar.
