Each year a tree’s growth ring has two parts; one is wide and light colored, and the other is narrow and dark. This grows during the wet spring and early summer when the tree has a lot of sap, and the cambium cells giving rise to the trunk growth are large and thin walled.
As the summer winds down and the transition to the cooler autumn occurs, the tree’s growth rate slows.
This results in the cambium cells becoming smaller and thicker-walled.
This absolute dating method is also known as dendrochronology.
It is based on the fact that trees produce one growth ring each year.
