The Forest Reserve Act of 1891 is a law that allowed the President of the United States to set aside forest reserves from the land in the public domain. This act passed by the United States Congress under Benjamin Harrison's administration. Harrison issued proclamations establishing 13 million acres (53,000 km2) of land a Forest Reserves; Grover Cleveland proclaimed 25 million acres (100,000 km2) and William McKinley proclaimed 7 million acres (28,000 km2). In 1907 a law was passed limiting the President's authority to proclaim Forest Reserves in certain states and renamed the existing "Forest Reserves" as "National Forests." A further provision to the act was added in 1939, when President Roosevelt added new standards to the preservation of "Forest Reserves" and "National Forests". Senato
