This bill prohibits the Big Cypress National Preserve in Florida from being designated as wilderness or as a component of the National Wilderness Preservation System. The National Park Service currently manages Big Cypress National Preserve, which is a freshwater swamp ecosystem of 729,000 acres. 

In general, development activities, commercial activities, permanent structures, and roads are prohibited in wilderness areas. In contrast, natural preserves typically allow some development activities, such as hunting or oil and gas exploration.
