In northeastern Kansas, before it was disturbed by the arrival of white settlers in the eighteen fifties, tall grass prairies and deciduous forests were both represented. These two contrasting types of vegetation overlapped widely in an interdigitating pattern which was determined by distribution of moisture, soil types, slope exposure and various biotic factors.

The early explorers who saw this region, and the settlers who came later, left only incomplete descriptions, which were usually vague as to the locality and the species of plants represented. As a result, there is but little concrete information as to the precise boundaries between the forests and grasslands, and opinions differ among ecologists. No representative sample of either type remains.

It may be assumed that the plant communities existing one hundred years ago and earlier were far more stable than those of the present that have resulted from man's disruptive activities. This stability was only relative, however. Within the last few thousand years since the final withdrawal of the Wisconsinan ice sheet, fairly rapid and continual change must have occurred, as a result of changing climate, the sudden extinction of various large, dominant mammals, and finally the impact of successive aboriginal cultures.

The land north of the Kansas River had been a reserve for the Delaware Indians. This land was thrown open to settlement as a result of two separate purchases from the tribe, in 1860 and
