years since statehood, the State has disposed of, or exchanged, about 1,628,079 acres of Trust lands. A total of 9,228,787 acres of Trust Land remains. Almost all of the lands are under one or more leases for natural resource uses and commercial development purposes. About 87 percent of the Trust lands are in the Common School Trust and approximately 90 percent of the Trust revenues go to that Trust.
