Hunnewell Visitor Center

A warming climate and increasing environmental pathogens pose an existential threat to the Arboretum’s collection of some 16,000 woody plants, trees and shrubs that are able to survive in our climate. This one hour walk will highlight the impact of climate change and increasing pathogens on key species in the Arboretum’s collection, describe some of the research initiatives underway to mitigate the effects of global warming and new pathogens, and identify the challenges and opportunities we face in improving our urban canopy.
