Tribal Historic Preservation Officer
A Tribal Historic Preservation Officer or THPO is an officer in the United States "designated by a federally-recognized Indian tribe to direct a program approved by the National Park Service and the THPO must have assumed some or all of the functions of State Historic Preservation Officers on Tribal lands."
Each THPO prepares a Tribal Historic Preservation Plan, which is used to "advise Federal agencies on the management of Tribal historic properties..."
