# List of bison conservation herds in North America

Conservation of American bison is heavily tied with conservation herds and the protected areas they roam. American bison occupy less than one percent of their historical range with fewer than 20,000 bison in conservation herds on public, tribal or private protected lands. The roughly 500,000 animals that are raised for commercial purposes are not included unless the entity is engaged in conservation efforts.
