Dutch Elm Disease (DED) is a fungal disease affecting elm trees. The fungus is spread by both a native and an introduced bark beetle whose larvae tunnel under the bark and create distinctive feeding channels or "galleries". The first signs of the disease is the upper branches dying and leaves turning yellow in mid-summer. Gradually the damage spreads to the rest of the tree which eventually dies.

Do Not Prune Elm Trees Between April 1st & August 31st

It is illegal in Saskatchewan to prune elm trees during the ban period. One of the best ways to reduce the spread of elm trees is not to prune elms during the summer months when the beatles are the most active. Freshly pruned trees also attract the beetles to them. To keep the trees healthy you may trim them outside of the ban period. Keeping your trees healthy helps them fight off the disease.

It is also illegal to use, transport, store or sell elm wood. There are also Regulations to restrict the use, transport, storage and sale of elm logs.
