Each year a tree gains another ring as it grows; the thickness of which depends on the amount of growth. In a year with ideal growing conditions, trees will produce a wider ring than in a year with poor conditions, and all the trees in the same region are likely to display the same general chronological growth pattern, despite any local ecological variations.
