Lecture: Secrets from Very Old Trees

Thursday, May 2, 2019

Ever think about really old trees - and what they may have witnessed?  Many trees in the Midwest have survived flood and famine, wars, and wayfarers.  Dr. M. Ross Alexander of Midwest Dendro, LLC, and Dr. Christine Rollinson, of the Morton Arboretum, will describe their wide-ranging study of trees in the area and how climate change may be reflected in their growth.  The technology they use can also date old beams in houses and buildings to approximate the age of a structure. As part of the study, the scientists have taken core samples of some veteran Riverside trees and can tell us with a great degree of precision how old the tree is. Join us when the trees secrets are revealed. The winner of the “How Old is that Oak Contest” will also be revealed.

This event is sponsored by the Library, the Landscape Advisory Commission and the Frederick Law Olmsted Society.
