Dr. Herb Bormann (Duke PhD, Ecology, 1952) returns to the Bormann plot to observe oak and hickory regeneration failure more than 50 years after his studies. March 2006 with Acer rubrum fully in bloom. For more on ecology and statistics of the forest-change data of the Bormann plot and the Duke Forest at large, see: (1) Bormann, F.H. 1953.
