Mike Mease of the Buffalo Field Campaign joins us on the phone to talk about the American buffalo. Also known as the bison – and recently named the US's national mammal – the creature faces culling in the state of Montana.
"The only ones that aren't behind fences, grass-fed and essentially domesticated are the Yellowstone herd. They're the genetic jewel, they were saved from the descendants of 30 to 60 million that used to roam continental North America." [04:12] – Mike Mease
