Our National Wilderness Preservation System (NWPS) currently consists of 643 individual Wilderness Areas covering more than 105 million acres of public lands managed by the Forest Service, Park Service, Bureau of Land Management and the Fish and Wildlife Service. Under the Wilderness Act of 1964, Congress must pass legislation to add or remove any areas from the NWPS. The 106th Congress passed eight Wilderness bills which were signed by President Clinton and added over 1 million acres to the NWPS. The 107th Congress passed 4 wilderness bills adding over 500,000 acres to the NWPS. See the links below for details!
