Emerald Ash Borer and City Trees


Actions being taken right now on ash trees on City-owned property:

Assessments
City crews are continuing to monitor the infestation and assess trees for the presence of EAB and its impact on their health.

Injection treatments
Wherever possible, trees have been assessed and identified as candidates for injection treatment using TreeAzin, a bio-insecticide which is injected directly into the base of the tree with no hazard to the user or environment.  Property owners are not permitted to treat City trees.  Information about TreeAzin is available on the BioForest  website, the manufacturer of the TreeAzin.

Any City trees that have been injected have been tagged with a small brass tag so they can be easily identified.

Removal of dead and hazardous trees
City crews are removing dead and hazardous trees on City property and identifying locations for replanting as part of on-going operations.  Efforts are being made, wherever possible, to replant with suitable replacements as soon as possible.

If there is an unhealthy looking Ash on City property in front of your house, please call the City of London to have the tree assessed for maintenance or removal. If you're not sure if the tree is on City property or your property, please call our Forestry Dispatcher.  Property owners are not permitted to trim or remove City trees.  Inquiries can also be emailed.

Emerald Ash Borer Management Strategy
The City had hired a consultant to assess the current EAB infestation levels and prepare a strategic management plan for consideration by Council.  The following are the two documents relating to the City of London EAB Strategy.
