Hosted each year at Antelope Island State Park, the Bison Roundup is a primary tool utilized to help ensure the continued health of one of the nation’s largest and oldest public bison herds. To help people better understand how the bison herd is managed, you can visit Antelope Island State Park on the day of the event and experience it first-hand. | Utah Division of State Parks

Watch how a herd of European bison crosses a road in eastern Poland. Poland is home to Europe's largest land mammal—the majestic European bison (żubr). Thanks to decades of conservation, Poland's population hit a record 3,060 in 2025, with over 2,855 roaming free in forests like Białowieża & Bieszczady. From near-extinct to thriving!
