What is a tree ring?
Quick Answer
A tree ring is a yearly layer of wood formed as a tree grows. Counting rings can reveal a tree's age and past growing conditions.
The Full Story
Most temperate trees add new wood in distinct rings each growing season, creating a record of age and growth. Wide rings often indicate favorable conditions, while narrow rings can reflect drought, cold, or stress. This field is called dendrochronology and is used by scientists to study climate history, fires, and environmental change. Some long-lived trees, such as bristlecone pines, have exceptionally old ring records.
