This office has the honor of protecting Mohican and Munsee cultural sites and burial places from disturbance. It also works to repatriate cultural items to the community and to return ancestors held by museums or other institutions for respectful reburial.

It carries this out primarily through participating in Government-to-Government consultation under two federal laws pertaining to cultural resources: Section 106 of the National Historic Preservation Act and the Native American Graves Protection and Repatriation Act.

The Historic Preservation program fields an average of 800 such federal, state and local project reviews annually across its service area spanning six states where the Tribe has ancestral territories.
