Each of the 326 Indian reservations in the United States are associated with a particular Native American nation . Not all of the country's 567 recognized tribes have a reservation--some tribes have more than one reservation, some share reservations, while others have none . In addition, because of past land allotments, leading to some sales to non-Native Americans, some reservations are severely fragmented, with each piece of tribal, individual, and privately held land being a separate enclave . This jumble of private and public real estate creates significant administrative, political, and legal difficulties . </P> <P> The collective geographical area of all reservations is 56,200,000 acres (22,700,000 ha; 87,800 sq mi; 227,000 km), approximately the size of Idaho . While most reservations are small compared to U.S. states, there are 12 Indian reservations larger than the state of Rhode Island . The largest reservation, the Navajo Nation Reservation, is similar in size to West Virginia . Reservations are unevenly distributed throughout the country; the majority are west of the Mississippi River and occupy lands that were first reserved by treaty or' granted' from the public domain . </P>
