ATLANTA (AP) — Georgia’s congressional delegation introduced legislation Wednesday to protect some of the ancestral lands of the Muscogee tribe as a national park and preserve.

The proposed Ocmulgee Mounds Park and Preserve would be Georgia’s first national park. The area along the Ocmulgee River downstream from Macon in central Georgia includes mounds and other cultural or historic sites of significance to the Muscogee. About 700 acres (283 hectares) surrounding seven mounds have been federally protected since 1936.

The proposed park and preserve would include many more miles (kilometers) of land along the river, much of it already under some level of government protection, and add cultural and historical interpretation in consultation with the Muscogee (Creek) Nation, whose people were forcibly removed to Oklahoma roughly 200 years ago. It would be the first national park co-managed by a removed tribe.
