A tree ring represents that the tree has experienced a cycle of changes in its growing environment. Usually, the climate is a change cycle every year, so the tree ring also represents the growth situation in a year. According to the number of tree rings, we can infer the age of the trees, which can be used to check the age of the forest. However, due to the rhythmic activities of cambium, sometimes several tree rings can be generated in one year, which is called false tree ring. For example, citrus plants can produce three tree rings a year. Therefore, the tree age calculated by tree ring can only be an approximate number.
