A warming climate and increasing environmental pathogens pose an existential threat to the Arnold Arboretum’s collection of some 16,000 woody plants, trees and shrubs that are able to survive in our climate. This one hour walk on January 4 at 11 am 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. This tour covers slightly over 1 mile in distance over terrain of asphalt, crushed granite, and mulch. Please be sure to dress for the weather and wear comfortable, closed toe footwear you don’t mind getting dirty.Meet at the Hunnewell Visitor Center. Register at www.arboretum.harvard.edu
