How to Determine's a Tree's Age WITHOUT Cutting it Down
Updated: May 20, 2022
Counting rings on a tree is one way to estimate the age of it but what if you want to estimate the age of the tree while it is still living? Well, there is a very simple equation to help get a rough estimate of the age without having to break out the chainsaw. All you need is to know the type of tree, a way to measure around the trunk of the tree (about 4 1/2 feet from the ground), and the growth factor of the tree you are measuring (listed below).
First, at 4 and 1/2 feet from the ground, measure trunk for the diameter, all the way around. Divide the diameter by 3.14.
Then, multiply by the tree's growth factor (listed below).
