Tallgrass Prairie bison herd, Bison herd in Flint Hills, Kansas.
The Tallgrass Prairie bison herd lives within the Tallgrass Prairie National Preserve in the Flint Hills, grazing across roughly 1,100 acres of native grassland. The animals roam freely across this open rolling terrain, naturally shaping the landscape through their grazing and movement.
The herd was established in 2009 when thirteen bison from Wind Cave National Park arrived to restore the prairie ecosystem. This reintroduction reflected broader efforts across North America to bring grasslands and their native species back to health.
The herd grazes year-round across the preserve, shaping the grassland just as herds once did centuries ago. Watching them move through the tall grass gives a sense of how the prairie landscape functioned in the past.
The best way to see the herd is to walk the designated trails throughout the preserve, where you can spot the animals without interfering with their space. Since the bison are wild and unpredictable, keeping a respectful distance is important for your safety and theirs.
The bison here come from a special lineage with no detectable cattle genes, making them valuable for genetic preservation across North America. This genetic purity helps researchers and conservationists restore other herds with confidence.
