Three Green Aliens

On Saturday, April 13 at 4 pm in the Cornwall Library, (30 Pine St, Cornwall, CT) Tom Zetterstrom will present a free slide show and talk about three aggressive alien plants, a shrub, a vine and an herbaceous thicket, that are invading and destroying our landscape.  This talk will examine the ecological impact both locally and regionally of Japanese Barberry, Asiatic Bittersweet and Japanese Knotweed.  It will include plant identification, the importance of mapping and will describe biological, preventive, mechanical and chemical control methods.  Tom will also include other “best management practices” to prevent the loss of native habitat to these perniciously vigorous invaders.

Tom Zetterstrom is a fine arts photographer, tree preservationist, an Elm Watch founder and environmental activist whose work spans five decades and numerous awards. In 2013 he received the Ossenbrugen Award from the CT Urban Forest Council for his efforts to “educate and promote positive change regarding trees and plants”. As a photographer, Tom is noted for his Portraits of American Trees. The presentation is sponsored by The Cornwall Conservation Commission and the Cornwall Land Trust.  Refreshments will be served.
