Protecting Specimen Trees and Standing Forests from Asiatic Bittersweet

When: 
Saturday, October 9, 2021 - 11:00am to 1:00pm
Where: 

Berkshire Botanical Garden

Bittersweet, the tree-killing vine, can undo a century of forest succession in a generation by strangling, encapsulating, and collapsing trees, resulting in dramatic reduction of carbon sequestration and eco-system services. Learn how land trusts, parks and campuses are efficiently and effectively defeating invasive vines and shrubs, maintaining trails and restoring inherent beauty and balance to natural areas.

This program includes a lecture followed by an invasive identification and management workshop from noon to 1:00 p.m.


Tom Zetterstrom’s photographic record reveals a changing landscape impacted by species decline, alien plant invasion and forest collapse. In these talks he will describe projects in Connecticut and Massachusetts that have protected trees in natural and community forests. In 1999 he co-founded Elm Watch. Tom received the 2011 Public Awareness of Trees award from the National Arbor Day Foundation and the 2013 Connecticut Urban Forest Council’s meritorious service award for efforts “to educate and promote positive change regarding trees and plants.” He is recognized for his Portraits of America Trees exhibition and his photographs are in the collections of 43 museums nationally.
