Online Speaker Series 2020: “Lightning Strikes VanDusen”2020-11-30 6:30pm - 7:30pm
Presented by: Samantha Sivertz
In June 2020, three trees in the giant sequoia grove at VanDusen Botanical Garden were struck by lightning, leaving the ground littered with broken branches, wood fragments and shredded bark. The trees will likely survive but will carry lightning scars for the rest of their long lives. How did these sequoias withstand the shock of over 100 million volts? In this presentation Plant Documentation Technician Samantha Sivertz will explore what happens when a tree is struck by lightning, tell stories of past lightning strikes at VanDusen, and discuss how botanical gardens deal with this destructive weather phenomenon.
