Protecting Brandon's Urban Tree Canopy: Downtown Ash Trees Impacted By Invasive Pests To Be Removed

Brandon, MB – The City of Brandon Parks Team has observed a notable decline in the health of ash trees within downtown Brandon, particularly affecting black and Manchurian ash varieties. 

This deterioration results from a combination of factors, including limited growing spaces, recurring drought, environmental damage, and exposure to winter road salts. Additionally, these conditions have been aggravated by an infestation of the invasive Cottony Ash Psyllid (CAP), commonly referred to as jumping tree lice. CAP feeds on the sap of ash leaves, leading to leaf curling, discoloration, early leaf drop, and canopy thinning. At present, there are no effective pesticides or known natural predators for CAP, making treatment options extremely limited. 

To prevent further spread and safeguard healthy trees, the City will remove 71 affected ash trees throughout downtown Brandon. The removal process will start on Mon, Sept. 15, 2025. Most trees slated for removal are located along 7th St., 9th St., 10th St., and 11th St. between Pacific Ave. and Louise Ave., with a small number also on Rosser Ave.  

In spring 2026, the City will initiate a replanting program featuring a diverse selection of tree species designed to enhance the resilience of Brandon’s urban tree canopy. 

“The health of Brandon’s downtown ash trees is vital to the character and resilience of our city,” said Bryce Wilson, City of Brandon Manager of Parks. “While removing these trees is a difficult decision, it is necessary to stop the spread of invasive pests and protect the remaining urban canopy. Our team is committed to restoring and enhancing our green spaces, and we look forward to launching a replanting program in spring 2026 that will introduce a variety of species for a stronger, healthier future.”
