  • Saturday, November 15, 10:00 am – 10:45 am – Tree Mob: The Oldest Tree in the Arboretum

    Long before anyone dreamed of this landscape becoming the Arnold Arboretum, a white oak grew quietly on the slope of today’s Peters Hill. Years passed and Arboretum staff eventually incorporated this very old tree into the collections, making it possibly the oldest accessioned tree in the landscape. Join Assistant Curator Miles Sax for a Tree Mob on November 15 at 10 am to learn about this oak, what the landscape looked like before it was an Arboretum, the science of tree age, and how the Arboretum manages those trees that we never chose to plant but which are a treasured part of our collections nonetheless. This is a members-only event, so sign up now at https://arboretum.harvard.edu/support/

  • Tuesday, August 23, 3:30 pm – Tree Mob: Solar Array Pollinator Meadow, Live and Online

    Tree Mobs™ are interactions with scientists or other specialists at the Arnold Arboretum that provide another pathway to enjoy and learn in the landscape. Next Tuesday, August 23, we’ll hold our first ever hybrid Tree Mob in our landscape and live via Zoom. Join us at 3:30 pm.

    The solar array meadow at the Arboretum’s Weld Hill Research and Administration Building is now teaming with plant life and buzzing with pollinators. Join Arboretum Horticulturist Brendan Keegan to learn about the solar array and the native, wild-collected plants growing around it. To register for the Zoom, click here. This event will also be presented in-person at the Arboretum’s Weld Hill Research Building at 1300 Centre Street, Boston, MA 02131. To sign up for the in-person event, click here.

  • Wednesday, January 13, 3:00 pm – Tree Mob: New Year, New Nest, Online

    Whoooo cares about New Year’s Eve when every evening in December and January is cause for celebration? Walk through the Arnold Arboretum during these winter months and you may hear a mating pair of great horned owls (Bubo virginianus) calling to one another as they prepare for nesting season. Will they use last year’s nest? Find a nook in a dead tree? Or repurpose a red-tailed hawk nest? Brendan Keegan will share a Powerpoint on the nesting habits of great horned owls as well as provide best practices for ethically observing these seldom seen raptors. Join us via Zoom on January 13 at 3:00 pm. Free, but registration required by clicking HERE.
