Dutch Elm Disease
Dutch Elm Disease (DED) is an invasive fungus spread to American Elms via the native elm bark beetle. This disease has killed off many American Elms in urban forests but with the help of the Province of Manitoba it has been managed for a number of years. The Province of Manitoba's website provides , signs, symptoms, and the management program for Dutche Elm Disease.

Why should we be concerned?
EAB is highly destructive, it’s larvae feeds off the nutrient conducting vessels of native ash trees, killing the tree. EAB is hard to detect in the early stages and once found it is too late. In Brandon we have a high quantity of ash trees (~15,000) and the presence of this invasive beetle would be devastating to our urban forest.
How can we prevent EAB from coming to Manitoba?
PLEASE DO NOT MOVE FIREWOOD!
Do not move firewood long distances. Buy it locally and leave it where you bought it.
Be vigilant. Learn about the signs and symptoms of EAB and report symptomatic ash trees or ash tree products to Sustainable Development’s tree care line at 945-7866.
Tell others. An informed public is the first line of defense against this destructive pest. Learn more about EAB signs and symptoms
