Stop the Beetle! Protect Edmonton’s Elm Trees

June 25, 2012

Alberta has the largest stand of Dutch Elm Disease-free elms in the world. The preservation of this valuable resource requires constant vigilance against the beetles that spread this deadly tree disease.

Dutch Elm Disease is caused by a fungus that clogs the elm tree’s water conducting system, causing the tree to die. The fungus is primarily spread from one elm tree to another by three species of beetles. The City of Edmonton monitors for the beetles and is part of a provincial effort to protect our elm trees.

During Dutch Elm Disease Awareness Week (June 22-June 28, 2012), the City of Edmonton offers these reminders and tips for keeping our elm stand strong:

It is illegal to prune elms between April 1 and September 30.
It is illegal to transport or store elm firewood at any time.
Immediately dispose of all elm wood by burning, burying or chipping.
Keep your elm trees healthy. Water generously from April to mid-August.
Between October 1 to March 31, remove dead elm branches and trees as they can provide beetle habitat.
Report all suspect trees to the Dutch Elm Disease Hotline at 1-877-837-ELMS.
