The National Wilderness Preservation System of the United States protects federally managed land areas designated for preservation in their natural condition. It was established by the Wilderness Act (Public Law 88-577) upon the signature of President Lyndon B. Johnson on September 3, 1964. The National Wilderness Preservation System originally created hundreds of wilderness zones within already protected federally administered property, consisting of about 9.1 million acres (3,700,000 ha). As of August 2008, a total of 704 separate wilderness areas, encompassing 107,514,938 acres (43,509,752 ha) had been set aside. With the passage of the Omnibus Public Lands Act in March 2009, there are now 756 wilderness areas.
