Ken Burns: Bison Range gives hope to species survival – ‘The American Buffalo’

The tale of the American buffalo is first tragic and then slightly hopeful. So documentarian Ken Burns decided to film those two eras as parts of a three-act story, leaving the last act for future generations to tell.

“Maybe my great, great grandchildren will be interested in doing Act Three in retrospect, as we hope it will be a very positive thing, with the Great Plains in large measure the Serengeti again,” the multi-Emmy winner said.
