BADLANDS NATIONAL PARK - Badlands National Park has donated 152 buffalo to Native American tribes as part of an ongoing effort to keep the park herd at a population the park's habitat can support.

Thirty-three bison went to the Oglala Sioux Tribe, 25 to the Standing Rock Tribe of North Dakota and 94 to the Spirit Lake Tribe of North Dakota, according to the park.

Park employees and volunteers recently rounded up 441 bison in the park. Blood samples were taken to test for disease and pregnancy, and each animal's height and weight were recorded.

The largest animal processed this year was a 12-year-old bull that weighed almost 2,300 pounds. The oldest animal was a 27-year-old cow, according to Veterinarian Boyd Porch.
