Table 1: Jeannie’s High Trail sample data for damaged forest.
Jeannie's High Trail:

The first area that was surveyed was the damaged forest area located off of Jeannie's High Trail.  This forest is estimated to be between 20 and 30 years old.  Even though it has been quite some time since the area was damaged, you can see that the trees are still limited in number and size from the data table shown.  In all only 32 trees met the minimum DBH size of 5 cm.
