1,000 American Elms still remain in our Ontario landscape, over 100 years old, standing resistant to Dutch Elm disease (DED). We, at Puslinch Naturally Native Trees Nursery, have progeny from these parent trees and are now offering them for reintroduction into the environment.
In 10 years, super resistant DED elm progeny will be available from the University of Guelph elm recovery program. It is our hope that both natural and super DED elms will be planted together. Why? Even though emphasis is on DED we must also consider climate change. The naturals have a vast genetic base that may offer adaptive abilities to our changing weather.
