Summary

Congress says the Tucson Mountain unit should be made larger by adding nearby lands worthy of National Park status, and that Saguaro National Monument should be officially recognized and protected by law as a National Park. Saguaro National Monument was created by Presidential proclamation in 1933, and the Tucson Mountain unit was set up in 1961. The Tucson Mountain boundaries were widened in 1976 and the Rincon unit in 1991. The Tucson Mountain unit now faces growing threats to its natural resources, scenery, and wildlife habitat. Those threats hurt public use, learning, safety, and the quiet of the wilderness areas set aside in 1976, and the growth of the greater Tucson, Arizona, area is making the threats worse.
