What type of lands and rivers are protected by the OI Implementation Act?
The landscape within the wilderness proposal is diverse, ranging from river canyons over a thousand feet deep to vast expanses of sagebrush and grassland plateaus that provide habitat for sage grouse, pronghorn antelope, bighorn sheep, songbirds, raptors, and numerous rare plant species. More than 230,000 acres of lands proposed for wilderness are upland plateaus and 224,000 acres are classified as low or moderate hills. This high desert, sagebrush steppe habitat is not included in existing designated wilderness in Idaho and is generally underrepresented in the National Wilderness Preservation System. The river canyons in Owyhee County have been called the largest concentration of sheer-walled volcanic rhyolite and basalt canyons in the western United States. Many of the canyons are more than 1,000 feet deep, nearly twice as deep as the Washington Monument is tall. River enthusiasts come from around the country to challenge the famous white water rapids of these rivers.
