How do you know the age of a tree?

The age of the tree can be determined visually. It is necessary to include attentiveness and logical thinking. If the tree has already been felled, look at the number of rings inside the trunk; the more rings, the older the tree. If the tree is intact, look at the bark, try it to the touch (very rough and dark bark in an old tree), look if the roots are on the ground. Estimate the height and take a close look at the crown.
