Tree Mob™!: 'Tis the admire a tree


Elizabeth Wolkovich, PhD, Associate Professor of Forest & Conservation Sciences, University of British Columbia, and Visiting Scholar in Organismic and Evolutionary Biology, Harvard University

1 Session: Thursday, December 20, 3:00pm
Location: Valley Road, Arnold Arboretum, Acc. # 358-82*A


Elizabeth (Lizzie) Wolkovich has traveled eastward from British Columbia to speak again about citizen science that tracks tree phenology at the Arnold Arboretum. She’ll share data that indicate that changing climates are affecting phenophases such as budburst and leafout in trees, and seed-sprouting and dormancy in woody plant seeds. Using several years of results from the Arboretum’s Tree Spotters program, Lizzie will explain how and why arboreta are such valuable resources for researchers. We will meet with her at Acc. 358-82*A, Quercus alba, a white oak originally from Georgia, and compare it to a neighboring oak, native to the Arnold Arboretum, to consider the role of genes and environment in the lives of these two specimens. Gather on Thursday, December 20 at 3:00pm on Valley Road at Acc. # 358-82*A to admire and compare these trees.

What’s a Tree Mob™?

Tree Mobs are interactions with scientists or other specialists at the Arnold Arboretum, and provide another pathway to enjoy and learn in the landscape. Experts share little-known facts about our living plant collection, its relevance today, and its importance to future generations. A Tree Mob may attract a small group or a large gathering—we won’t know until it takes place. Join us in the landscape and discover something new.

What can I expect?

Plan to spend approximately 30 minutes learning about an interesting component of our collection. You can then continue your exploration of the Arnold Arboretum on your own. Tree Mobs are time, date, and location specific.

How does it work?

We will communicate about Tree Mobs by various means (see below). Using mobile technologies, such as a smartphone with location-awareness enabled, you will be able to navigate to the event location. You can also view and print a map we will provide with the day’s Tree Mob location on our website. With directions in hand, proceed to the designated meeting place to participate in our experiment for spontaneous learning.
