Abstract
Continuity of observation over an extended period of time is a difficult but vital phase of the study of the natural vegetation of any area. Such continuity is difficult to obtain. The vegetation may be destroyed or the investigator may move before sufficient time has elapsed to permit any significant development. Dr. J. E. Potzger realized the difficulties inherent in a long-time study but he also considered such studies valuable. Hence in 1950 he and Mrs. Potzger published the results of their studies on several areas in Versailles State Park. These were planned as the ground work for a long-time study of succession.
