Q.22 How do we compute the age ofa living tree?

To estimate the age of a living tree, folowing steps are required

(i) Measure the circumference of the tree trunk (at about 4.5 feet above the ground).

(ii) Calculate the diameter of the trunk. This is done by dividing the circumference by 3.14 Divide this (i.e., diameter) by 2 to get the radius. 

(iii) Determine the growith factor, A tree's growth factor can be seen from the data avialable or by measuring the rings of a dead tree from the same species. 

(iv) Multiply the diameter and the tree species average growth factor and the so done calculating suggest the approximate age of the tree in years.
