It can be very difficult to calculate the age of a tree if you don't know when it was planted. However, it is
possible to estimate the tree's age through an approximation technique that is based on the circumference of its
trunk.
Appreciate the age of the tree. Please select the tree type and specify the stem circumference / diameter in
cm or inch. The stem circumference is measured at a height of 1.00 m (3.3 ft.) to 1.50 m (4.5 ft.).
