For millennia, tens of millions of bison roamed the plains of North America. By the end of the 19th century, westward expansion and overhunting at the hands of settlers had devastated these populations. The fate of one of the America’s most iconic animals teetered on the edge of extinction.

Hannah Kaplan looks at how collaboration between the Bronx Zoo, many other organizations, and Indigenous Peoples helped pull one of North America’s most endangered species back from the brink.
