Which native american group lived as nomads following the buffalo herds?

Plains

Explanation:

At the core of the Lakota culture is the buffalo or Tatanka. For thousands of years, the lives of the Buffalo Nation and the Lakota people were spiritually and physically interconnected - as herds roamed free across the North American plains, this nomadic tribe followed.

As long as the North American buffalo roamed free and bountiful, the Plains Indians were able to remain sovereign. Buffalo were their lifeline—the Indians had a symbiotic relationship with them, and always honored the mighty beasts for the many blessings they provided.
