They stop at a station to see how foresters
estimate the age of a tree without cutting it
down in order to count its annual growth rings.
A teacher demonstrates the use of an increment
borer to take a small core sample of the tree.
Counting the rings in the core
sample reveals the tree's age.
In the middle of the forest, students lie on the forest floor and quietly observe the canopy and listen to the forest sounds. Here they identify layers of the forest: canopy, understory, shrub, and ground layer.
