List of former U.S. National Forests This is a list of all the former National Forests in the United States. These units were renamed, disestablished, combined with other units or split apart during reorganizations of the U.S. Forest Service system. There was particular turnover during the first decade of the 20th century, when the forest system was reorganized several times, most notably on July 1, 1908. Many smaller holdings of fewer than 100000 acre were combined. In the 1920s a short-lived program created several National Forests from excess portions of military facilities. Within two years these transfers were reconsidered and rescinded.
