What do Bison eat?

Bison are considered a keystone species. The way they graze and interact with their pastures contribute to healthy grasslands. 

Compared to Cattle which feed just about 26 different types of grass, bison are known to take about 146 different plants and grasses as their food source. It is for this reason, that bison take maximum use of all-natural plants available on pasture, bush, and treed terrain.

Because bison are constantly on the move and a preference for grasses they leave behind habitat for other species. Their wallowing and interaction with the land is essential to support and grow the number of species on the land they graze.
