The National Park Service proposes to authorize agreements between the National Park Service and federally recognized Indian tribes to allow the gathering and removal of plants or plant parts by designated tribal members for traditional purposes. The agreements would facilitate continuation of tribal cultural traditions on traditionally associated lands that are now included within units of the National Park System without a significant adverse impact to park resources and values. The proposed rule respects tribal sovereignty and the government-to-government relationship between the United States and the tribes, and would provide system-wide consistency to this aspect of National Park Service-tribal relations. The proposed rule would provide opportunities for tribal youth, the National Park Service, and the public to understand tribal traditions.
