Tale of the Tree Rings

The study of tree rings (dendrochronology) is a tool used in a wide range of science fields – fire history and fire ecology, paleoclimatology, archaeology, biogeography, isotope geochemistry, paleoecology, and much more. The UA Laboratory for Tree-Ring Research (LTRR) – recognized worldwide as a preeminent center for the advancement of tree-ring techniques – is a phenomenal resource for dendrochronoly education. The LTRR taught educators how to bring this science into their classrooms with a range of hands-on experiences for students.
