Lamar Buffalo Ranch

The Lamar Buffalo Ranch is a historic livestock ranch in the Lamar River valley of Yellowstone National Park, in the U.S. state of Wyoming. As an early contribution to the conservation of bison, it was created to preserve one of the last free-roaming American bison herds in the United States. The ranch was established in 1907 when 28 bison were moved from Fort Yellowstone to the Lamar Valley in the northeast corner of the park.The herd at the Lamar Buffalo Ranch was maintained as a semi-domesticated source of additional bison to enhance the park's natural herd.
