Despite their immense size, bison still have to worry about predators. The constant disturbance keeps woody vegetation from encroaching, nonnative plants from invading, and biodiversity from declining as a result of competitive exclusion between species [12]. The grasses covering these open landscapes serve as powerful carbon traps, with slender leaves removing CO2 from the atmosphere and returning it to the soil through an extensive system of roots.
