Dutch elm disease (DED) is a deadly disease that can affect any elm tree.

Since its introduction from Europe in 1930, it has destroyed millions of American elm trees across North America.

DED is prevalent in Manitoba, Saskatchewan and Montana. At present, Alberta has the largest DED-free American elm stands in the world.

In 2017 the provincial American elm inventory was updated, and demonstrated that there are at least 600,000 elms growing in Alberta municipalities, rural properties, shelterbelts and Provincial parks. These elms are valued at over $2 billion dollars.

Removing and replacing DED infected trees pushes the costs associated with losing valuable trees higher as it can cost over $500 dollars to remove a tree (an estimated $300 million for tree removal alone in Alberta) with the additional cost of replacing the tree.

Alberta has been fortunate to remain DED free for many years however, in 1998 one elm tree in Wainwright was confirmed to have disease. The tree was immediately removed and burned. It is believed that firewood brought into the province was the source of infection. Alberta is still DED-free.
