Do you have an ash tree?

IMPORTANT

Some ash trees located on your property near the street may be public. In that case, they are handled by the city. To verify the ownership of an ash tree near the street, check on your certificate of location or call 311.

Here are 3 simple ways to identify an ash tree:

  1. The ash tree has opposite composite leaves.
  2. Its leaves are composed of an odd number (5 to 11) of leaflets (small leaves devoid of a leafstalk).
    Each leaf is paired with another leaf on the opposite side and each branch with another branch in a symmetrical way.
  3. Unlike those of maple trees, the leaflet of the tip of an ash leaf has no teeth.

Property with several ash trees

If you have several ash trees on your property which require treatment or removal under the new emerald ash borer by-law, you can submit an action plan to extend the treatment or removal over a two year-period if your ash tree has a diameter of 300 centimeters  or more. If you would like to pursue this alternative, please refer to articles 13 to 20 and schedule B of the emerald ash borer control by-law.
If your property has wooded areas that are greater than 0.3 ha, you are required to submit a forest management plan even if there are no ash trees on your property. For more information, please refer to articles 13 to 20 and schedule B of the emerald ash borer control by-law.

You can submit your action plan or your forest management plan for approval by e-mail or postal mail to the attention of the director of the Service des grands parcs, du verdissement et du Mont-Royal at the following addresses:

Treating or felling my ash tree

I must fell my tree if…

• My ash tree is dead or the treetop is showing more than 30% dieback.

• It is not vigorous enough to preserve.

If these characteristics apply to your ash tree, you are required to have it felled.

You could be eligible for financial assistance.

 What to do:

  1. Make a Tree Felling Permit request through your borough. A felling permit is required for each ash tree whose diameter, measured at 1.4 m from the ground, is equal to or greater than 10 cm.
  2. Once you obtain your permit, get quotes for tree felling.
  3. Fell your tree or have it felled.
  4. Dispose of ash wood in accordance with the fight against the spread of the emerald ash borer.

Tip: Because of the risk associated with felling a tree, make sure that the contractor you choose to fell your ash tree has proper liability insurance.


I have to treat my ash tree if...
  • My ash tree appears healthy: its foliage and its crown are abundant and relatively dense.
  • The treetop is showing less than 30% dieback.

If your ash tree has these characteristics, you are required to have your ash tree treated in accordance with by-law 15-040.

You could be eligible for financial assistance.

When

Between June 1 and August 31.

The pesticide subsidized by the city for the treatment of ash trees is TreeAzin. It is a product with low toxicity for which the owner is not required to obtain a pesticide permit.

Tips

Free disposal of ash wood on the city’s processing sites:

Just give the form to your contractor. This applies only to branches or parts of the trunk with a diameter of 20 cm or more. If your tree is being pruned, you can get a form in an Accès Montréal office.

Wood processing techniques that are compliant with the by-law:

All processing techniques that completely destroy the emerald ash borer or the parts of wood where it may live (such as shredding into chips no larger than 2.5 cm on at least two sides, sawmilling with shredding of parts with bark, etc.)
