It is also used in radiocarbon dating to calibrate radiocarbon ages.

New growth in trees occurs in a layer of cells near the bark.

A tree's growth rate changes in a predictable pattern throughout the year in response to seasonal climate changes, resulting in visible growth rings.

Each ring marks a complete cycle of seasons, or one year, in the tree's life.

The contrast between these smaller old cells and next year's larger new cells is enough to establish a ring, thus making counting possible.My mission was born from an overwhelming need among dendrochronologists for a permanent repository of information that was free to the public, easily understandable, and as comprehensive as humanly possible.Come back and visit from time to time to learn more about new or updated software, new educational tools, new institutions conducting tree-ring research, new publications, and more!In his Trattato della Pittura (Treatise on Painting), Leonardo da Vinci was the first person to mention that trees form rings annually and that their thickness is determined by the conditions under which they grew. S., Alexander Catlin Twining (1801–1884) suggested in 1833 that patterns among tree rings could be used to synchronize the dendrochronologies of various trees and thereby to reconstruct past climates across entire regions.During the latter half of the nineteenth century, the scientific study of tree rings and the application of dendrochronology began.
