Tree Mob™!: Of Worms and Forests


Brendan Keegan, Gardener II, Arnold Arboretum of Harvard University

1 Session: Wednesday, September 18, 4:00pm
Location: Meadow Road and North Woods, Arnold Arboretum, Acc. # 365-2014*E


Do you know that New England has no native earthworm species? Or that these amazing organisms, much loved by farmers and gardeners, threaten northern forest ecosystems? Or climate change models are being revised upward to account for their unseen, but industrious, productivity? If not, join us to consider the mighty earthworms with Arnold Arboretum gardener Brendan Keegan. You'll learn some simple tricks for finding and identifying earthworms, examine a few truly invasive species, and discuss the role these incredible creatures play in our yards, gardens, and forests. Meet at Acc. # 365-2014*E, Aesculus pavia, on September 18, at 4:00 p.m. We'll mover from there into the nearby North Woods in search of worms and evidence of their efforts.


Parking: Park along the Arborway and enter at the Arborway Gate. Walk along Meadow Road, following the Tree Mob signs.


Public Transportation: Take the MBTA Orange Line to Forest Hills. At the upper level of the station, cross Washington Street and go to the right. Walk uphill on the sidewalk that parallels the down ramp. Continue until you reach the Forest Hills Gate (approximately a 10 minute walk). Enter the gate and follow the road to the ponds. Turn right at the ponds onto Meadow Road and follow the signs to the meeting location. Or take the 39 Bus to South and Sedgewick Streets. Walk west on Custer Street to the Arborway and cross at the lights to the Arboretum. See directions above from Arborway Gate.

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.
