The complete county distribution, spread across 2 Kentucky counties. Every occurrence record falls in one county, so these sum to the total. Counties from GBIF and US Census boundaries.

Kentucky’s 2,144 bison records have essentially one address: Big Bone Lick State Park in Boone County accounts for 2,139 of them, and every record in the set arrives through GBIF rather than iNaturalist. That lopsided map is the story, because Big Bone Lick has been drawing bison, and the people who study them, for thousands of years.

An Ice Age crossroads

The salt and sulfur springs at Big Bone Lick drew mammoths, mastodons, and giant bison through the last ice age, and the bones they left behind made the site the birthplace of American vertebrate paleontology. Much of the park’s enormous record count reflects specimen material tied to that fossil legacy rather than living animals. Long after the ice age herds vanished, bison still walked traces through the Bluegrass to reach the licks, until hunters killed off the state’s animals around the turn of the nineteenth century.

The herd that remains

The park keeps a small live bison herd today as a nod to that history, and reports run year-round, strongest from May through September when calving and summer grazing keep the animals out on pasture. A fenced herd is still made of wild animals: half-ton cows and bulls near a ton, quick to charge when crowded. The only other records in the state are a handful in Carter County.

Status in Kentucky

The overlay treats the bison as native to its mapped Kentucky range, and USGS NAS does not list it as nonindigenous in the state, but Kentucky has no wild, free-ranging bison; its modern presence is a managed park herd. The IUCN lists the species globally as Near Threatened.
