Ontario’s Niagara Escarpment is home to some of the oldest trees in Canada. This remarkable information was obtained by counting the rings from collected core samples of living White Cedars perched at the edge of the escarpment face.

Artist and horticulturalist Lorraine Roy will speak about how tree rings record a forest’s history, the relevance of tree ring research for environmental protection, and the personal and cultural lessons they teach us. The talk will be illustrated with entrancing images from her collections.

As seating is very limited, please email Greg Kennedy, SJ at gkennedy@ignatiusguelph.ca if you plan to come!

Free-will offering.
