City Begins Removing Marked Ash Trees in Lake Ontario Park

Lake Ontario Park

City of Kingston contracted crews are removing marked ash trees starting in Lake Ontario Park today. The ash trees were marked for removal due to the emerald ash borer (EAB) infestation.

“This is part of our multi-year plan to remove City ash trees endangered by the emerald ash borer for the safety of residents who use City properties. These trees will be replaced with trees of a different species in the fall as the City works toward double its urban tree canopy by 2025,” says Troy Stubinski, operations manager, public works.

Some replacement trees will be planted in new locations to avoid existing infrastructure, such as power lines.

Emerald ash borer

Approximately 600 ash trees in good condition are being treated to protect them from the emerald ash borer and will need to be retreated every other year (about 300 will be treated each year).  The treated trees will have their health reevaluated yearly. Treating all the City’s ash trees is cost-prohibitive and not sustainable.

Many more ash trees will be removed and replaced with other species over the next few years.

To see where ash trees are being treated, go to CityofKingston.ca/EAB.

Homeowners may also visit that webpage to find out more about how to deal with their own ash trees. Stubinski suggests calling an arborist for help.

The EAB Impact Cost Mitigation Plan outlines how the City will deal with the 3,500 ash trees that were on City property. It is available for review at CityofKingston.ca/EAB and includes details on how the City is adhering to the Migratory Bird Convention Act.

The presence of emerald ash borer was verified in Kingston in 2013. The invasive beetle kills ash trees over the course of two to six years.
