The color and width of tree rings can provide snapshots of past climate conditions. The light-colored rings represent wood that grew in the spring and early summer, while the dark rings represent wood that grew in the late summer and fall. One light ring plus one dark ring equals one year of the trees life.
What do tree rings signify?
What do tree rings tell us. The underlying patterns of wide or narrow rings record the year-to-year fluctuations in the growth of trees. The patterns, therefore, often contain a weather history at the location the tree grew, in addition to its age.
What does it mean when a tree has thin rings?
The rings show the layers of growth of each year the tree has lived. Smaller rings show shorter or slower growing seasons which means either the temperature was low or the tree didnt have enough water to grow very much. Tree rings can also tell us about the environmental conditions that the tree was growing in.
What causes dark tree rings?
New wood formed in a tree during spring and summer is light in color. Toward the end of a growing season, new cells formed are smaller and have darker thicker walls. The wood is more dense and darker. That annual pattern creates rings.

How do you tell how old a tree is without cutting it down?
You can get a rough estimate of the age of a tree without cutting it down and counting the rings. The girth of a tree can be used to estimate its age, as roughly a tree will increase its girth by 2.5cm in a year. So, simply measure around the trunk of the tree (the girth) at about 1m from the ground.
