It is well known that many treeless areas existed in Ohio before white settlement. These areas, of various ecological character and usually restricted in size, were in a few cases fairly extensive—embracing from fifty to one hundred square miles. The term "prairie" was rather generally applied to them, although more exact terms were not wanting. Like the various forest associations, these treeless areas have played an important role in influencing industrial and cultural phases of human life in Ohio (1). The present paper is an attempt to reconstruct such areas, now destroyed or obscured by secondary successions induced by white men. In this as in the preceding paper on the virgin forests of Ohio (2) the question of succession has been intentionally postponed.
