The Mission for the Tribal Historic Preservation Office (THPO) of the Round Valley Indian Tribes is to preserve, maintain, and revitalize the culture and traditions of the Round Valley Reservation.

The THPO assumes many responsibilities of the California State Historic Preservation Office - to ensure the identification, protection, and preservation of archaeological and historic sites within the boundaries of the Round Valley Reservation and on lands throughout our traditional territories and ancestral homelands.

A critical mission of the THPO is to participate in the mandated procedures of the Native American Graves Protection and Repatriation Act (NAGPRA) to allow:

1. The identification and repatriation of objects sacred to the Round Valley Reservation
2. The repatriation and reburial of ancestral remains
3. The protection of contemporary and ancestral burials

The overarching mission of the THPO is to help meet the cultural preservation needs as voiced by the members of the Round Valley Reservation.
