newest NRA, designated in 2009. The Land and Water Conservation Fund provided funding for the purchase of land at several NRAs. Management Three federal agencies manage the 40 NRAs. The National Park Service, in the Department of the Interior, manages 18, the U.S. Forest Service, in the Department of Agriculture, manages 22, and the Bureau of Land Management, in the Department of the Interior, manages one. One NRA, Whiskeytown–Shasta–Trinity, comprises three units, two of which are Forest Service and one is National Park Service. The NPS sites are stand-alone units of the National Park System, while the USFS sites are all part of national forests except Land Between the Lakes. Several of the larger USFS NRAs are managed equivalent to a ranger district, but most are designated areas within one. The Green Mountain National Forest is the only one with two NRAs. The Forest Service manages its NRAs as "showcases" of its management standards so that their programs, services, and facilities should be better than and models for its other recreation sites. The USBR operates dams in the West, with eleven NRAs built around them, while the USACE primarily operates dams in the East, with reservoirs or areas near four part of NRAs; three more are based around reservoirs operated by other agencies. As the primary focus of land management is recreation (rather than conservation), limited land use such as grazing, logging, and mineral leasing is permitted only if it does not interfere with the recreational use of the land. The establishing legislation of each NRA usually specifies multiple purposes of the designation. Hunting is by default banned in areas of the National Park Service unless explicitly permitted by law; 15 of 18 NRAs of the NPS allow hunting – and it is generally permitted in National Forest lands – in accordance with local rules. List of national recreation areas The Mississippi National River and Recreation Area and Big South Fork National River and Recreation Area share many features with the NRAs but are classified by the NPS with the national rivers and are not listed here. The USFS has four additional designated "recreation areas" that have similar management practices but are not listed here. The USFS and BLM do not collect visitor data for most sites, marked with an asterisk.
