Students collected point-center quarter data along transects. At random points along
the transect, the circumference of the nearest trees and the distance from the
transect were measured and the species noted.
A typical data (see below) set shows that there were very few species of tree in the Smith Woods, as is typical in a climax forest in the Eastern United States.

Gaps are important features in forest regeneration. Here, Tom Glover discusses their
significance in the midst of one such gap caused by a tree fall in the Smith Woods.
The three different fungi shown here were all found within a few meters of each other.
