At one time it is estimated there were over 20 million bison in North America. The bison grazed on the grasslands that ran from Canada to Texas. The grassland of North America is the second largest continuous ecosystem in the World. The bison played an important role in the grassland's ecosystem and health. Cattle, if properly managed, can play the same important role. At the 2S, we have worked hard and revived the native bunch grasses of the prairie (Big Blue, Little Blue, Side Oats Grama, Indian, and Switch grasses). Today, we rotationally graze our cattle herd on these same native grasses that grow tall on our savannas.
