Quick Summary

A "false ring" in forestry is a layer of wood that is less than a full season's growth and may not encircle the entire trunk. These can occur when a tree's growth is interrupted, such as by drought during the growing season, and then resumes, creating the appearance of an additional ring.12

Dendrochronology is the scientific study of tree rings used to date past events and interpret past climates. It relies on the fact that many trees produce annual growth rings, the width of which is influenced by factors like precipitation and temperature. By analyzing sequences of these rings, scientists can extend climate knowledge back thousands of years. False rings can pose a challenge to dendrochronology but also offer insights into weather patterns.32

This, however, is a false ring, because there is a gradient of increasing cell-wall thickness and decreasing cell diameter at the start of the false ring and another gradient of decreasing cell-wall thickness and increasing cell diameter at the end of the false ring.
