Figure above shows the number of new wilderness areas established by Congress each year. Read our data disclaimer. Data last updated on 4/17/13 (The Vieques Wilderness, which was accidentally omitted when designated in 2001, was added, then removed due to contention over the legality of the designation; acreage for the National Park Service portion of the Great Sand Dunes Wilderness was also updated).
