To determine the diameter growth rate of trees, divide the width of the cross section by the number of rings. For example, the cross section of the tree below is approximately 9.3 cm. There are 14 annular tree rings, so the diameter growth rate of this specimen would be 9.3 cm / 14 years, or 2.3 cm/year.
Determine the comparative growth rates of the trees in the form below.
