Yes. Like humans, trees do age but their lifespan varies for different species. One of the ways of finding out the age of a tree is by counting the rings within their branches and the trunks. These rings usually appear as alternating rings of dark and light shaded wood; you will need to count the number of dark rings to find out the tree’s age. For example, if a tree has 65 dark circles, it is 65 years old. These unique rings are known as growth rings. They are created every year when a new layer of wood is added to the branches and trunk of the tree. The light-coloured rings are known as the springwood and are generally wider in size because trees grow most during spring. The darker rings are known as summerwood and are relatively thinner because the growth of trees slows down during summer.
