The city of Montreal said its ash-borer beetle prevention efforts bore fruit in 2016, bringing the death of ash trees “under control,” and allowing the city to avoid the “massive, exponential die-off” experienced in other cities. Nearly 27,500 tees were treated with the pesticide TreeAzin in 2016. Another 37,000 are slated for treatment in 2017. All dead ash trees in at-risk zones were replaced in 2016, which limits the reproduction of the ash-borer beetle, part of the city’s approach to control the ash trees’ death and slowly replace them over time.

The city of Montreal spent $12 million to plant 16,143 trees on public municipal lands in 2016 as part of its canopy bolstering program, and another 13,000 trees were planted on non-municipal property. For 2017, the city is planning to plant another 24,500 trees.
