Learn about tree ring research from the University of Arizona LTRR.

Tree ring research is more than just determining the age of trees. Trees provide information about climate history that goes beyond rainfall or temperature change. The University of Arizona was a pioneer in the study of tree rings in the 1920s, and tree ring research has since become a field of study worldwide.
