American Bison (Bison bison) roam and graze the spring grasses across the more than 40,000 acre Tallgrass Prairie Preserve in Pawhuska, Oklahoma. At the time of the roundup, most of the approximately 2,000 head of bison had been herded towards the western side of the preserve in zones near the headquarters and corrals. 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.
