Since the Wilderness Act passed in 1964, Congress has designated nearly 110 million acres of federal wildlands as official wilderness. Official wilderness has the highest form of protection of any federal wildland.
Wilderness protection comes in many shapes and sizes — from designating new wilderness and national monuments to making sure our national forests are well managed and there are adequate trails for recreation.
With passage of the Wilderness Act of 1964 (P.L. 88-577; 16 USC 1131-1136), the United States charted a course new in the history of nations — to preserve some of the country's last remaining wild places in order to protect their natural processes and values from development. Today, thanks to the wisdom, foresight, and perseverance of many dedicated individuals, current and future generations will enjoy an enduring wilderness — in reality and in spirit.
