The main purpose of this legislation is to officially designate a specific area within the Ouachita National Forest in Arkansas as the "Flatside-Bethune Wilderness." This designation aims to protect the natural environment and preserve the area's wilderness characteristics for future generations. Key provisions of the legislation include the amendment of the Arkansas Wilderness Act of 1984 to add approximately 2,212 acres of land in the Ouachita National Forest to the existing Flatside Wilderness.
