How to Estimate the Age of a Tree (Without Cutting it Down)
To calculate the tree’s age you have to multiply the diameter by the growth factor. Diameter X Growth Factor = Approximate Tree Age. Treebeard’s Big Leaf Maple growth factor is approximately 4.7 and its diameter is 43.63
For this table, an estimate of generalized annual growth rate is determined based upon the number of annual increments present in the last (outside or most exterior) inch of wood (xylem). This measure estimates a growth rate by diameter (DBH) class.
