More than 250,000 families and individuals own about 35 percent (6.2 million acres) of northern forest areas. Small woodland owners are those who own between one acre and 1000 acres. They lay claim to the largest share of forest land. Companies that own paper mills, sawmills and other wood processing facilities own nearly 28 percent (5 million acres), including large tracts of northeastern United States woodlands. A handful of landowners own 14 percent (about 2.5 million acres) of northeastern forest. Owners of large tracts include individuals, families, and public and private companies. By definition, a large non-industrial forest landowner owns more than 100,000 acres. Investment institutions, such as banks, insurance companies, mutual and pension funds and university endowment funds, own about 15 percent (more than 2.6 million acres).
