American Bison (Bison bison) roam and graze the spring grasses across the more than 40,000 acre Tallgrass Prairie Preserve in Pawhuska, Oklahoma.

The green grasses and blackened trees are the result of prescribed spring fires, which coupled with grazing bison, make up two major processes vital for maintaining a healthy prairie ecosystem. The bison are currently threatened by an outbreak of Mycoplasma bovis. © Morgan Heim
