NAGPRA's "disposition" provisions establish procedures for the inadvertent discovery or planned excavation of Native American cultural items on federal or tribal lands, which includes private and state lands within the exterior boundary of an Indian reservation. These provisions do not apply to discoveries or excavations on non-federal or tribal lands, but the repatriation provisions do apply to Native American cultural items if they come under the control of an institution that receives federal funding.
