Wild bison return to Illinois prairie after nearly 200 years
In a historic moment for conservation, wild bison have returned to the Illinois prairie for the first time in nearly two centuries. The Nature Conservancy has successfully reintroduced a genetically pure herd to the Nachusa Grasslands, marking the first time wild bison have roamed east of the Mississippi since the 1830s. This ecological milestone aims to restore the health of the tallgrass prairie, as the bison’s natural grazing habits boost biodiversity and support other native species. The project offers a powerful model for rewilding and connecting communities with their natural heritage.
