Want to try at home? Follow the steps below!
Step 1: Identify your tree and find it on your age chart.
Step 2: Measure up 54 inches from the ground. This is Diameter Breast Height, or DBH.
Step 3: Measure around the tree at this height to find the circumference, in inches.
Circumference: ___
Step 4: Divide the circumference by mathematical pi (3.14). This will give you the tree's diameter.
Circumference / 3.14 = Diameter
Step 5: Multiply the diameter by the growth rate number for the tree species from the chart below to find the approximate age of the tree.
Diameter X Growth Rate = Tree Age
