Question

how to measure age of trees ?

Answer 1

hey there,

Try to find out when it was planted. This is the only way to know for certain how old a tree is, since all of the other methods are simply estimates. If possible, conduct research to find out when the tree might have been planted. Ask older residents of the neighborhood or look at old photographs to try to date the tree. Count the tree's whorls. Some species of trees, such as particular conifers, produce annual branch whorls. Counting branch whorls can be used to estimate the tree's age. This method is not as accurate as cutting down the tree and counting the rings, but it's a way to estimate the tree's age without having to kill it.[1] Count the number of branch whorls above chest height. Multiply the diameter by the growth factor.[2] A tree's growth factor is the measurement of the width it gains annually. If you know the average annual width of tree ring for that species, you can multiply it by the diameter of the trunk to estimate the tree's age. Different species' growth factors are dependent on their environment - for example, forest trees grow faster than city trees - so this method for determining a tree's age is truly an estimate. Measure the circumference of the trunk in inches. Use the trunk width at 4.5 feet (1.4 m) off the ground. Calculate the diameter (circumference divided by pi). Multiple the diameter and the tree species' average growth factor. This will give you the approximate age of the tree in years. You can figure out a tree's growth factor by searching online or measuring the rings of a dead tree from the same species.

hope this helps!

Answer 2

If you know when the tree was planted, you can easily and accurately determine itsage. The second most accurate way to estimate tree age is to count the annual rings of wood growth. Annual rings can be counted using two different methods. You can extract an increment core from the tree using an increment borer. The only guaranteed method is knowing when the tree was planted, but tree growth rings are also highly accurate – to a point – in determining the age of a tree. These growth rings can be counted when the tree is either alive or dead, in addition to various other non-invasive methods to roughly predict a tree’s age.
