Confirmed Cases of Dutch Elm Disease in Regina

The City of Regina has confirmed 26 cases of Dutch elm disease as of July 15, 2026. The infected trees have been removed to control the spread.

Cases of Dutch elm disease have been on the rise since 2024 when numbers of diseased trees increased from 24 cases in 2023 to 84 in 2024. In 2025 there were 87 cases.

The City is launching a public awareness campaign urging residents to watch out for signs of the disease, like yellowing leaves that do not fall off the branch, and to report them right away.

Elm wood is an ideal place for the beetles that carry the disease to lay eggs, making this a key factor in managing the outbreak. Provincial regulations state that elm tree wood cannot be stored, used, marketed or transported for any purpose.

Residents can help prevent the spread of Dutch elm disease and protect Regina’s urban forest by:

• Reporting suspected cases to Service Regina at 306-777-7000 or online at Regina.ca.
• Not storing, transporting or using elm wood as per provincial regulations.
• Inspecting trees regularly for signs of wilting, yellowing leaves or dead branches, especially in summer.
• Avoiding elm pruning between April 1 and August 31, when Dutch elm disease-carrying beetles are most active.
