Inventoried Roadless Areas are a group of United States Forest Service lands that have been identified by government reviews as lands without existing roads that could be suitable for roadless area conservation as wilderness or other non-standard protections. The Inventoried Roadless areas include approximately 60,000,000 acres (240,000 km2) of land in 40 states and Puerto Rico. Most of these lands are in the western portion of the lower 48 states and Alaska. Idaho alone contains over 9 million acres (36,000 km2) of inventoried roadless areas. The inventoried roadless areas range from large areas with wilderness characteristics to small tracts of land that are immediately adjacent to wilderness areas, parks and other protected lands.
