Pruning ban for Elm trees in effect until Saturday, August 31, 2019

For immediate release: April 18, 2019 - 9:00am
CY19-328

The City reminds residents that the provincial ban on pruning elm trees is in effect until Saturday, August 31, 2019.

The ban ensures that elm bark beetles, which transmit Dutch elm disease (DED), are not attracted to the freshly pruned trees at the time when these beetles are most active.  Anyone wishing to prune elm trees during the ban must obtain a permit.  Please call the City’s Parks Division at 306-975-3300 for information.

DED was first discovered in Saskatchewan in 1981 and continues to be found in more areas of the province every year.  The first case of DED was identified in Saskatoon in July 2015.  The infected tree was removed and city-wide surveillance of the elm tree population continues through the use of elm bark beetle traps.  

DED is caused by a fungus that clogs the tree’s water conducting system, which eventually causes the tree to die within one to two seasons.  Early symptoms of the disease usually appear in July when the leaves on one or more branches wilt, curl, turn yellow, and remain on the tree. 

The most effective management strategy for the elm bark beetle is to deprive it of its breeding habitat by keeping elm trees healthy and removing dead and dying branches.  It is necessary to dispose of any branches or wood from a fallen elm tree and either remove the stump or render it uninhabitable.  Under no circumstances can elm wood be stored for firewood or other purposes.

Elm tree removal can occur at any time of the year; however, all elm material must be transported to the nearest approved disposal site in the municipality where the elm was removed.  The Saskatoon Landfill is the only site in the city approved for elm tree disposal.

By following provincial regulations and maintaining your trees, all residents can help prevent the spread of DED.  Anyone suspecting an elm tree is displaying symptoms of DED is asked to please contact the City at 306-975-2890.
