This paper is the result of an intensive study of the vegetation of the prairie. The study extended over a period of ten years. It deals with the life histories, distribution, and relative importance of the dominant grasses in a central area of the tall-grass prairie. This area includes the grasslands of the western one-third of Iowa and those of approximately the eastern one-third of Nebraska. On the south it extends into Missouri and Kansas to the Kansas River. North- ward it includes a small portion of southwestern Minnesota and a larger one of southeastern South Dakota.
