The Secrets of Tree Rings: What Our Trees Can Tell Us About the History of our Environment (150-05-05-18)
Janet Sinner Endowed Horticultural Speaker Series
Saturday, May 5, 9:00 a.m. - 11:00 a.m.
Alan Branhagen, Arboretum Director of Operations and published horticulture author
Brita Lorentzen, Postdoctoral Research Associate, Cornell Tree Rings Laboratory
In honor of the Arboretum’s 60th anniversary and as the very first of the Janet Sinner Endowed Horticultural Speaker Series, join us to learn more about trees and time. We first learn about tree rings as children- one ring for each year of growth- but who really pays attention to these rings and why do they matter? Join Brita Lorentzen, Postdoctoral Research Associate at the Cornell Tree Ring Lab, and Alan Branhagen, Arboretum Director of Operations and published horticultural author, to learn what trees can tell us about the history of our environment! Brita will discuss her work as a dendrochronologist (a scientist who dates environmental change and archeological artifacts through tree rings), and overview her fascinating work with trees from the Midwest to the Mediterranean. You’ll discover how tree rings can help scientists determine historic temperatures, rainfall, fire events, and even health of the ecosystem. Alan will share more about the ecological importance of trees, and highlight some of the historic trees at the Arboretum. You’ll leave with a new appreciation for these gentle giants and what they’ve lived through, and a new understanding of how to help them continue to thrive.
