Prunus orientalis 213-2001A
Tree Mob™! At the Arnold Arboretum

Winter moths (Operophtera brumata) are now a scourge in eastern Massachusetts and beyond. You may have observed them crowding your lighted entryway on November and December nights. But before they become moths, the winter moth caterpillars wreak havoc as they eat their way through buds and leaves of trees and shrubs in springtime. Some of their favorite food sources are maples, oaks, apples, birches, and blueberries, which they can significantly defoliate. Arboretum horticulturist Rachel Brinkman is studying the relationship between winter moth larval hatch date and the amount of defoliation caused. You may have seen evidence of her experiments…groupings of mesh bags over the ends of branches, primarily in the Peters Hill section of the Arboretum. Join us on Wednesday, April 6 at 4:00pm on Peters Hill at Acc. # 213-2001*A, Malus orientalis, to learn about Rachel’s research and how it may inform our treatment and preservation of the living collections.

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.
