Dear Felix Nwafor,

Please have a look at these useful PDF attachments.

Thanks!

Hi I would like to comment If you know when the tree was planted, you can easily and accurately determine its age. 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 growth rings of a tree at Bristol Zoo England. Each ring represents one year; the outside rings, near the bark, are the youngest.

There is a way How to Tell the Age of a Tree Without Cutting it Down:

- Wrap the tape measure around the tree at about four and a half feet above the ground. This measurement is the tree's circumference. ...

- Use the circumference to find the diameter of the tree. ...

- Determine the age of the tree by multiplying the diameter by the growth factor.

Telling the Age of the Tree So when the tree is cut. The layers appear as alternating rings of light and dark wood. Click the cross section of the tree ring above to view the whole ring as it came from the tree. Count the dark rings, and you know the tree's age. Study the rings, and you can learn much more.

AGE OF TREES IN TROPICAL RAINFORESTS ESTIMATED BY TIMING OF WOOD DECAY: The age of trees in tropical rainforests where there are no annual dry seasons cannot be obtained by counting annual growth rings because such rings do not develop. However, the decay of wood in the humid tropics appears to be related to time and this relationship may provide a method for estimating the age of trees that have hollow (decayed) cores. So I believe Timing of Wood Decay would be Appropriate for your Research.... Regards

Count the annual rings.

Thank you so much Prof. @Arvind Singh for the wonderful materials. I so much appreciate.

Thanks Jonah Withers. Am happy to learn you use same method in fishery.

Thanks Ahsan Siddiqui for detailed answer. I appreciate

Anatomically, many tropical trees of India possess ring porosity, marginal axial parenchyma bands and difference in fibre wall thickness (Parenchyma like fibres), that helps in determination of tree age.

Thanks!

Dear Dr Sangeeta Gupta,

Please is there formula for estimating tree age based on these variables you mentioned?

Refer the following that may be helpful to you:

These features can be counted on a tree disc, as they are the ones (wood element) responsible for formation of growth rings.
