You’ve probably seen the silhouette on a nickel or maybe spotted a cluster of brown dots from a highway overlook in Yellowstone. We call them buffalo. Technically, they’re bison—Bison bison bison if you want to get all scientific about it—but to the Lakota, they are Tatanka.
That word carries a weight that "bison" just can't touch. It’s not just a name for a 2,000-pound herbivore with a bad attitude and a thick coat. It’s a word that defines a relative, a provider, and a spiritual anchor.
Honestly, the story of the bison is kinda the story of America itself: massive, wild, nearly destroyed by greed, and now, somehow, figuring out how to come back. It’s a narrative of 30 million animals shrinking down to just a few hundred before a few "eccentric" ranchers and Indigenous leaders stepped in to stop the bleeding.
The Great Slaughter: Why the Tatanka Almost Vanished
It wasn't just "overhunting." Let’s be real. The near-extinction of the bison in the late 1800s was a calculated strategy.
By the mid-19th century, the U.S. government realized they couldn't easily "subdue" the Plains Tribes as long as the Tatanka were around. The bison were a walking grocery store, hardware shop, and temple. If you had the bison, you had independence.
So, the "Great Slaughter" began.
Hunters weren't killing for food. They were killing for hides to belt industrial machinery in Europe or just for the tongues, which were considered a delicacy. Sometimes, they didn't even take that. Passengers on trains would literally shoot bison out the windows for sport, leaving the carcasses to rot in the sun.

By 1884, a population that once shook the earth with its hooves had dwindled to roughly 325 wild individuals.
Think about that. From 30 million to 325. That’s not a population dip; that’s a biological ghost story.
The Turning Point in Deadwood
If you’re ever driving through South Dakota, you've gotta stop at Tatanka: Story of the Bison. It’s this place just outside Deadwood, established by Kevin Costner (yeah, that Kevin Costner).
It’s not just a tourist trap. It features this massive bronze sculpture—the third largest in the world—showing 14 bison being pursued by Lakota riders. It depicts a "bison jump," an ancient and incredibly efficient hunting method.
The site serves as a reminder that the Lakota didn't just hunt the bison; they lived alongside them in a symbiotic loop. When the bison were healthy, the people were healthy. When the bison died, the "hearts of the people fell to the ground," as Crow Chief Plenty Coups famously put it.

So, where do we stand today?

As of early 2026, the numbers look great on paper. There are roughly 500,000 bison in North America. But—and this is a big "but"—most of those are livestock. They’re being raised for meat on private ranches, often behind high fences, sometimes even crossbred with cattle (the infamous "beefalo").
Only about 20,000 to 30,000 are managed as "conservation herds"—meaning they live somewhat like wild animals.
Why Genetically Pure Bison Matter
Here’s the thing: most bison today carry a little bit of cow DNA. Back in the day, ranchers tried to crossbreed them to make hardier cattle. It didn't really work that well, but it "polluted" the gene pool.
Today, places like Wind Cave National Park and Yellowstone are the gold standards. Their herds are considered "genetically pure." In fact, Wind Cave’s herd was instrumental in restarting populations all over the country.
But there's a problem.
Bison are nomadic. They want to walk. They want to graze across hundreds of miles.
In 2026, we’re seeing a huge push for "eco-cultural restoration." This isn't just about putting animals in a fenced-in park. It’s about returning them to Tribal lands where they can fulfill their ecological role again.

The InterTribal Buffalo Council: A New Era
If you want to know who’s actually doing the heavy lifting right now, look at the InterTribal Buffalo Council (ITBC). They represent over 80 tribes across 20 states.
They aren't just looking at bison as a museum piece. They’re looking at Tatanka as a way to:
- Restore the native prairie ecosystem (bison "wallows" create mini-wetlands for birds and insects).
- Provide healthy, lean protein to communities struggling with food deserts.
- Reconnect younger generations with their heritage.
Just recently, in late 2025 and moving into 2026, we’ve seen record-breaking transfers of "surplus" bison from national parks to Tribal lands. Instead of being culled or sold, these animals are going home.
Practical Steps for the Modern Traveler or Enthusiast
If this story moves you, don't just read about it. Go see them. But do it right.
- Visit the Right Places: Go to Wind Cave National Park or Custer State Park in South Dakota. The annual Custer State Park Buffalo Roundup (usually late September) is a visceral, loud, dusty experience you won't forget.
- Support Tribal Businesses: Buy bison jerky or hides from Native-owned companies like Tanka Bar. It puts money directly back into the communities leading the restoration.
- Respect the Bubble: Every year, someone tries to pet a bison in Yellowstone and ends up on a "tourons" Instagram page (or in the hospital). These animals can run 35 mph and jump 6 feet high. They are not cows. Stay at least 25 yards away.
The story of the bison isn't over. It’s a work in progress. We’ve moved from the era of "The Great Slaughter" to the era of "The Great Return." It’s slow, it’s complicated, and it involves a lot of politics—but the Tatanka are still here. And as long as they are, there’s hope for the prairie.
Next Steps for You:
Check the 2026 schedule for the Bison Conservation and Transfer Program if you’re planning a trip to the American West. Supporting local interpretive centers like the one in Deadwood or the Buffalo Museum in Jamestown, North Dakota, helps fund the education needed to keep these herds wild and protected.
