2025 Roundup | Fischer's Sleepy Bison Acres

Time to round up the bison! Bison are hardy creatures that don’t need much care throughout the seasons, but once a year, our team at Cross Ranch Preserve in central North Dakota rounds them up to check on them and select bison to transfer to Native Nations as part of our bison rematriation program. Watch the well-orchestrated process from the sky as the team uses trucks and ATVs to guide the bison into the corral. Video by Jessica Duttenhefner | The Nature Conservancy

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!
