A little over a hundred years ago, bison in Yellowstone were on the brink of extinction. Now, there are thousands of them wandering freely in the park. The focus has shifted from just preserving the herd to managing a successful population.
In an interview with OutKick OutDoors, Jessica Bowron, who is acting director of the National Park Service, referred to this revival as an “incredible conservation story.” It’s hard to imagine how far we’ve come.
Once, millions of bison roamed the Great Plains, but they were nearly eradicated from their historical territories. Bowron emphasized that restoring these populations required decades of meticulous scientific work and collaboration between the Park Service and numerous Tribal, state, local, and federal partners.
“To visit Yellowstone today and spot a wild bison in a lively ecosystem, I don’t think we could have envisioned that a century ago,” Bowron noted. It’s quite a turnaround.
Now, the bison from Yellowstone are contributing to conservation efforts far beyond the park’s boundaries.
Yellowstone bison are finding new homes
Through the Bison Conservation Transfer Program, Yellowstone collaborates with Tribal partners to relocate bison that have completed necessary quarantine steps. Since 2019, over 600 bison have been moved to 29 tribes across 13 states, with more than 200 transferred in just 2026, according to Bowron.
“This is one of the coolest aspects of this whole conservation effort,” she mentioned. After the transfers, each tribe manages its herd based on its unique needs and sovereignty.
“It’s a fantastic example of how we can grow and nurture conservation herds through these partnerships,” Bowron added.
However, even with this conservation success, challenges remain. Some regions still focus on rebuilding bison populations. At Yellowstone, Bowron explained that the main concern now is managing the healthy herd that exists.
“At Yellowstone, we’re mostly in the phase of managing the current herd successfully with our partners,” she explained. The Park Service also continues to seek opportunities for live transfers to tribes interested in developing or boosting their own conservation herds.
A conservation problem you want to have
The story of Yellowstone serves as a reminder that conservation victories take time. Bowron noted that building bison populations has involved years of scientific monitoring and teamwork across multiple levels of government.
Even after a species rebounds, the work doesn’t just stop. For generations, the focus was on whether wild bison could even survive in areas like Yellowstone. Now, the question has shifted: what happens when the comeback is successful?
Bison don’t recognize the boundaries of Yellowstone. They roam across vast landscapes, which means managing a thriving herd requires coordination between the Park Service and surrounding communities and agencies.
The fact that there’s a healthy herd to oversee—along with enough bison to help set up conservation herds in other locations—would have seemed unlikely a century ago.
For those who’ve experienced the delays caused by a bison casually claiming the road, it can be easy to forget how close we were to losing that opportunity entirely.
Now, seeing the bison in the park seems almost like an expected part of the landscape. It certainly hasn’t always been this way.
So yes, we can certainly call it a comeback.
