Ash tree deaths ‘under control’ now, city says
The city of Montreal said its ashborer 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’ deaths 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.
