High River - Crews will be conducting tree pruning on the 100 block of 3rd Ave SE on the mornings of Monday March 20 to Wednesday March 22, 2023.

Pruning is a part of annual tree maintenance specifically pertaining to Elm trees. A provincial mandate to help prevent Dutch Elm Disease permits Elm pruning from October 1 to March 31. Pruning includes removal of dead, damaged or diseased branches from healthy elm trees to eliminate breeding material for the beetles that carry disease.

Elm bark beetles (EBB) are active between April 1 to September 31 and can be attracted to the scent of fresh cuts. These beetles can cause infections in healthy Elm trees. Once Elm bark beetles infect the tree, it will die within a year.

Currently, Alberta and British Columbia are the last two locations in North America that are free of Dutch Elm Disease, with an estimated population of 1500 Elms within the Town of High River.
