If I have one or more ash trees on my property

Should I treat or fell my ash tree?
I should treat my ash tree if…...I should fell my ash tree if…
  • My ash tree has fewer than 30% dead branches.
  • It is healthy and treatment can keep it alive.
  • My tree is dead or has more than 30% dead branches.
  • It is not healthy enough to be kept alive.

 

Is my property in a high-risk area?
YesNo
I used the search engine to check my location and I should treat my healthy tree. I used the search engine mais je but I can still take action on a voluntary and preventive basis.

When and how should I treat my tree?

If my property is in a high-risk areaIf my property is not in a high-risk area

In high-risk areas, I am eligible for a cost reduction

I must have my tree treated between June 15 and August 31.

I’ll consult a specialist.

Outside at-risk zones, it is recommended to treat my ash tree in order to keep it alive.

I will consult a specialist.

If I have my tree felled

When and how should I have my tree felled?

How should I properly dispose of branches and debris after the tree is felled?

Pruning and felling (requirements and ideal times)

Conditions for obtaining a felling permit

Under the by-law, you must apply for a felling permit and fell your ash before December 31 of the current year if it is in one of the following conditions:

  • It is dead
  • It is in poor health and 30% or more of its branches are dead

You can also request a felling permit if your ash tree meets one of the following conditions:

  • Your ash tree is affected irreversibly by a disease or pest
  • It poses a threat to people's safety
  • It could seriously damage property
  • It impedes a construction project authorized by the city

4 easy steps to fell an ash tree in compliance with the by-law

  1. Apply for a permit in your borough.
  2. Once you have received your permit, get estimates for your felling.
  3. Have your ash tree felled ideally between September 15 and December 31. If you can't wait until September 15, consult the high-risk materials section. Special measures apply to felling ash trees in the summertime.
  4. Dispose of ash wood as directed in the by-law .

Tip : Because of the risks associated with felling a tree, make sure your contractor has good liability insurance. See the Web site siaq.org to find qualified contracots.

Pruning an ash tree

You can prune your ash at all times. However, the ideal time for pruning ash is between 15 September and 15 April. Pruning wounds made outside this period may attract females looking for ash trees weakened to lay their eggs.

Please note that special procedures apply to the pruning of ash trees. Consult the high-risk materials section for more information.

Spread of the emerald ash borer through ash wood

The transportation of ash wood through human activity is the biggest cause of the emerald ash borer’s spread in North America. The emerald ash borer can emerge from cut logs and branches up to three years after a tree is felled! So it’s important to know when ash wood can be transported and how to dispose of it to prevent ash borer propagation.

Rules for transporting and disposing of your ash wood

Between April 15 and September 15

  • If you have a few branches with a diameter of less than 20 cm, you can place them on the curb and call 311 to have the shredding service pick them up.
  • You must not move your ash wood from the site of pruning or felling, unless it has been shredded to destroy the ash borer
  • Your ash wood can be stored on site until it can be moved to a transformation site beginning September 15.
  • Beginning September 15, you have 21 days to shred your ash wood on site or take it to an institution or organization that can transform it appropriately to prevent propagation of the ash borer.
  • If you are the owner of a woodland with 25 or more ash trees that have a diameter of 15 cm or more measured at a height of 1.4 m from the ground, you have 60 days beginning September 15 to transform your ash wood on site or take it to an institution or organization that can transform it appropriately to prevent propagation of the ash borer.

To learn more about transformation techniques that are compliant with the by-law, please see the box at the end of this section.

Between September 15 and April 15:

  • If you have a few branches with a diameter of less than 20 cm, you can place them on the curb and call 311 to have the shredding service pick them up. Please note that this service ends at the end of November.
  • You can transport your untransformed ash wood away from the pruning or felling site.
  • You have 21 days after your ash tree is pruned or felled to transform your ash wood on site or transport it to an institution or organization that can transform it appropriately to prevent propagation of the ash borer
  • If you are the owner of a woodland with 25 or more ash trees that have a diameter of 15 cm or more measured at a height of 1.4 m from the ground, you have 60 days to transform your ash wood on site or take it to an institution or organization that can transform it appropriately to prevent propagation of the ash borer

Transformation techniques that are compliant with the by-law:

Any ash wood transformation technique that completely destroys the ash borer or the parts of wood in which the insect can hide: shredding into chips no longer than 2.5 cm on at least two sides, drying, grinding, fumigation or sawmilling that includes shredding of the parts with bark.

What is a high-risk area?

A high-risk area is an area that is likely to have emerald ash borers. It is determined by creating a 300 m radius around a site where one or more infested ash trees have been detected.

Obligations of ash tree owners in a high-risk area

If your home is in a high-risk area in 2016, you are required to treat all the ash trees on your property except for ash trees for which one of the following conditions applies:

  • Dead or ill trees with 30% or more dead branches
  • Ash trees with a diameter under 15 cm measured at a height of 1.4 m from the ground
  • Ash trees for which a felling permit has been granted under article 6 of the by-law
  • Ash trees that were treated the previous year with an approved ash borer pesticide that remains effective against the ash borer this year.

High-risk areas and woodlands with multiple ash trees

If your home is in a high-risk area in 2016 and has at least 25 ash trees with a diameter of 15 cm or more, you can submit an alternative action plan for the ash trees on your property. Please refer to articles 13 to 20 and the by-law’s annexes.
