 botanist Earl L. Core addressed the origin of the "sods" in 1973:
How did it happen that these grassy tracts were originally [prior to white settlement] treeless, when all the surrounding areas were covered with trees? No one really knows. Although the "sods" and "balds" have been the subject of much speculation, discussion, and research, no generally-accepted explanation has yet been proposed for their existence. Perhaps there is not really any one cause; the treelessness may be the result of a complex situation which may vary from place to place. Factors suggested may be classified as natural or artificial. Among the natural have been listed climatic, edaphic (soil), topographic, biotic and pyric (fire).
