Town treating nearly 3,300 public ash trees this summer to protect against the Emerald Ash Borer

Beginning this month, healthy public ash trees on streets and in parks across Oakville will be injected with TreeAzin™ to protect them against the Emerald Ash Borer (EAB). Approximately 3,300 ash trees will receive the treatment from one of the town’s service providers before the end of August.

“Oakville has the most aggressive EAB management program in the country,” Mayor Rob Burton said. “We’re treating approximately 75 per cent of the ash canopy located on town property. We’ve been able to take this approach because we implemented an early detection program that enabled us to act quickly to fight back against the infestation.”

In total, the town is treating approximately 6,000 municipal ash trees on a bi-annual basis for the next 10 years; forty per cent receive treatment in odd years, while 60 per cent receive treatment in even years. TreeAzin™ is a natural and safe bio-insecticide derived from the seeds of the neem tree. It provides two years of protection against EAB before it must be reapplied.

EAB is now infesting ash trees across the Greater Toronto Area. The invasive pest is responsible for killing tens of millions of ash trees in Canada and the United States since 2002. This year is believed to be a tipping point for the EAB population in the GTA, a time when ash trees will begin to decline rapidly if left untreated.

“With 80 per cent of Oakville’s ash trees located on private property, it’s important for residents to make a decision now about what they want to do with their ash trees,” said John McNeil, manager of Forestry Services. “We’re encouraging residents to treat their trees or have them removed and replaced. If they wait, their ash trees may become too infested to treat.”

During the next few weeks, a letter will be mailed to all Oakville residents updating them on the town’s EAB management program and providing helpful tips on what they can do to protect their ash trees. The town encourages all residents to have a certified arborist assess their ash tree(s) to determine the best treatment option.

In response to the EAB infestation, the town launched the Oakville Canopy Club in 2011. This innovative community outreach program educates residents about EAB and the town’s management program as well as provides the most up-to-date information on what residents can do to protect Oakville’s tree canopy.
