Writing teacher for the International Language Institute at the Universidad Pedagógica y

Agriculture and Life Sciences, and she is currently studying her master’s in Language Teaching at

Dendrochronology is the scientific method by which tree rings are used to provide dates. It
was formalized in the early 1900s by A.E. Douglass, who was the founder of the Laboratory of Tree
Ring Research (LTRR) at the University of Arizona, Tucson, AZ. The presentation discusses how the
researcher started her career at the LTRR as an undergraduate. She discusses the steps in taking
and preparing core and cross section samples. Furthermore, she will provide information on the uses
of dendrochronology in the fields of Environmental Science, Ecology, and Archaeology. As a
conclusion, the presenter will engage the audience in a practice activity to begin the process of
reading tree rings, creating patterns, and promoting outreach.
