Tree Mob™!:What Tilia Can Tell Us


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: Wednesday, June 5, 4:30pm
Location: Peters Hill Road, Arnold Arboretum, Acc. #1323-82*A


Dr. Elizabeth (Lizzie) M. Wolkovich, Associate Professor of Forest & Conservation Sciences at University of British Columbia, returns to the Arnold Arboretum for a phenology update. She will discuss how leafing times, flowering times, and fruiting times are related — or if there isn't really much of a relationship for some trees — and why it matters. Meet on Peters Hill at Acc. #1323-82*A Tilia americana (American basswood), a species on the Peters Hill Tree Spotters route, on Wednesday, June 5th at 4:30pm. Park along Bussey Street, keeping your tires off the sidewalk, and follow signs to the mob.


Parking: Park along Bussey Street to enter at Peters Hill Gate. Follow Peters Hill Road to the left. Tree Mob signs will be posted. 


Public Transportation: Take the MBTA Orange Line to Forest Hills. At the upper level of the station, cross Washington Street and go to the left to Washington Street Gate to Blackwell Footpath. Follow Blackwell Footpath to its terminus. Cross street and enter South Street Gate. Once inside the Arboretum, follow the paved road and turn left at the intersection, continuing to Bussey Street Gate. Cross Bussey Street to Peters Hill Gate and follow Peters Hill Road to the left.

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.
