<P> The tallgrass prairie is an ecosystem native to central North America . Natural and anthropogenic fire , as well as grazing by large mammals ( primarily bison ) , were historically agents of periodic disturbance , which regulates tree encroachment , recycles nutrients to the soil , and catalyzes some seed dispersal and germination processes . Prior to widespread use of the steel plow , which enabled conversion to agricultural land use , tallgrass prairies expanded throughout the American Midwest and smaller portions of southern central Canada , from the transitional ecotones out of eastern North American forests , west to a climatic threshold based on precipitation and soils , to the southern reaches of the Flint Hills in Oklahoma , to a transition into forest in Manitoba . </P>
