More than 107 million acres of our national lands now have wilderness protection. That's under five percent of the total U.S. land base -- and just two percent of the U.S. land base outside of Alaska. The Wilderness Society believes there are many more acres of federal public lands that should be protected as Wilderness, much of it in Alaska, including the coastal plain of the Arctic National Wildlife Refuge.

Other key areas for protection are found in the canyons of southern Utah and southeastern Oregon, ancient forests of the Pacific Northwest, Great Smoky Mountains National Park, Southern Appalachian national forests, Greater Yellowstone ecosystem, northern Rocky Mountains in Idaho and Montana, Florida's marine ecosystem, Colorado's Canyon Country, and others.
