This week, conservationists began their annual bison capture operation at Theodore Roosevelt National Park in western North Dakota. A bison roundup like this one isn’t for sport. Theodore Roosevelt National Park is located in North Dakota’s Badlands, a region typically marked by steep slopes, deep ravines, and winding gullies. The distance away from the animals also greatly reduces any chances of injuries to park rangers or the bison. This year, Theodore Roosevelt State Park plans to send around 400 bison to tribal nations.
