Tree Talk: April 10, 2018 – The Elm Recovery Project


The Elm Recovery Project at the University of
Guelph Arboretum

Many people today don’t recall the incredible canopy that the American elm (Ulmus americana) once produced over cities, rural roads and wild landscapes. With the introduction of Dutch elm disease into North America in the mid-twentieth century, hundreds of millions of elm trees were quickly killed – and the fungus continues to cause mortality in this species today.

There is hope.  Some elms appear to tolerate infection and remain healthy into old age; they are the survivors. Since 1998, the University of Guelph Arboretum has been conducting the Elm Recovery Project to study and archive these special trees.  Lovingly dubbed, ‘A Dating Service for Lonely Elms’ by CBC Radio, the Elm Recovery Project has been bringing these isolated survivors together while providing a helping hand on the path to seeing this majestic species tower over our Ontario landscapes once again.
