      The Cosmic Tree: A Universal Symbol of Life: Ginkgoes & Conifers

      Docent Katrina Scott will lead this interactive tour with stops for moments to reflect on specific trees and the stories associated with them. Were they revered or feared?  A home for deities or tricksters?  We will begin at the Walter Street Gate to visit the oldest ginkgoes at the Arboretum, then head up the Conifer Path and diverge to walk, rest, and reflect among various conifers, eventually ending by the yews near Bussey Brook and Hemlock Hill Road.

        The Trees are Speaking by Lynda Mapes

        The old-growth forests of Oregon and Washington play a vital role in the ecosystems there, supporting a wide diversity of life and sequestering carbon in enormous, long-living trees. The east coast, by contrast, has been logged and clear cut for generations and has precious little old-growth forest left. Join environmental journalist and Bullard Fellow at Harvard Forest, Lynda Mapes, for a talk about her book “The Trees are Speaking: Dispatches from the Salmon Forests.” In this thought-provoking new book, Mapes interviews scientists, loggers, and Indigenous activists to answer deep questions about the importance of old-growth forests, the conflicting desires around how to manage them, and how we can protect these forests into the future.

                Hundreds of mushrooms hide beneath the Arboretum’s canopies, silently blossoming into unique forms then withering away again just as quickly. Join local mushroom enthusiast Maria Pinto to search for these fascinating organisms on the Arboretum grounds, both edible and poisonous alike. Along the way you will learn what mushrooms to look for in different habitats and seasons, how they move through ecosystems, and what the Arboretum’s unique collections affect what mushrooms you might find here.

                Many are aware of Charles Sprague Sargent’s role as first director of the Arnold Arboretum, establishing it as the world-renowned institution it is today. Far fewer are familiar with the deep influence he had over how Americans have come to think about forests, forestry, and wilderness. Docent Paul Eldrenkamp will lead a tour that explores the history of the idea of the forest in America- and how Sargent helped shape that idea.

From the Royal Oak to the Charter Oak to the Emancipation Oak, from wine and whisky barrels to tall ships to the roof of Notre Dame, from King John to Shakespeare to Leonardo da Vinci, oaks have been inextricably entwined with the human experience. Join docent Paul Eldrenkamp as we learn more about the cultural history of oaks and explore what it is that makes them so useful, so distinct — and so essential.

                                The Explorers Garden rests in a microclimate just below the summit of Bussey Hill. This nearly five-acre site provides ideal growing conditions for many species that have been challenging to grow in less protected areas of the Arboretum. As such, it has proven to be a perfect testing ground for plants collected in the expeditions of E. H. Wilson in the early 1900s to the NACPEC  (North America-China Plant Exploration Consortium) expeditions of our own time. Join docent Marie Herbert for a guided tour to learn more about some of the plants showcased in this special collection and to hear stories of the plant exploration expeditions that brought them to the Arboretum.

This one hour tour through the landscape, led by docent Vicki Amalfitano, will highlight important Arboretum historical conservation efforts that have preserved distinct native and exotic species, and current efforts in our living collections to mitigate habitat disruption and climate impact. Learn about plant expeditions to preserve species in the face of climate change and new pathogens, research initiatives, as well as the Arboretum’s green initiatives and local collaborations to improve our urban canopy.
