This Bitternut Hickory seems to have some butt rot in the base of the tree.
Here the E. Cottonwood tree seems to have grown together at the base and further up the stem of the tree. Why was there a gap in the middle? Why did the tree wait to grow together further up the stem?
This tree does not seem to have the problem the Bitternut Hickory has. There is not as much decay happening with this tree.
