Overview: How Bison Are Saving America's Lost Prairie

8 minutes 28 seconds

Now Playing As: Captioned (English) (change)

The prairie landscape has come to symbolize the American heartland. But an ecosystem that once covered a vast swath of the continent has all but disappeared. Just a tiny fraction remains. But researchers and conservationists in Oklahoma may have hit upon two surprising keys to saving this lost ecosystem: bison and fire. Their efforts could help restore degraded grasslands around the world. Part of the "Overview" series.
