Can I cut my ash tree down?

It is the Town’s responsibility to cut it down, please do not remove the tree.

How long does it take for an ash tree to die?

Within two years of observing symptoms, most of the crown of the tree will be dead. Complete tree death typically occurs within five years, but may take as few as two to three years.

Why can’t my tree be treated?

Your tree may not meet the specific requirements for treatment. Trees not infested with EAB may still have other health issues. Look for extensive branch dieback, sparse foliage, conks (mushrooms) on the trunk or branches, or severe trunk injuries, these trees are not good candidates for treatment and may need to be removed for safety reasons. Treatments will cost more over time than removing and replanting with a tree that is resistant to EAB.

What does a tree infested with the emerald ash borer look like?

Initially, the top of the crown begins to thin and partially die. Epicormic sprouting, or sprouting from the main stem of the tree, may occur. The presence of insects below the bark leads to increased woodpecker activity, which causes the tree to look like it is losing patches of bark. In severe cases, the bark of the tree may split in places where the larvae are feeding beneath.

Direct evidence of the beetle can also be seen. Small, 1/8" D-shaped exit holes, where adult beetles emerged from the tree, will occur wherever a beetle emerges. This may be above eye level, so it is important not to discount a symptomatic tree if no exit holes are observed. If the bark is peeled back, the galleries where larvae have fed may also be observed; they are meandering and are usually filled with frass (sawdust and insect excrement). Larvae may also be visible underneath the bark. The cream-colored larvae have bell-shaped segments and can be up to 1.25" in length.

What is the treatment criteria?

Based on best practice at the time, ash trees that met the criteria below were candidates for treatment:

•  20 cm or greater in diameter
•  Overall health and structure
•  Location
•  Level of EAB infestation

Will the Town be treating trees on private property?

Private property owners and residents are responsible for all costs associated with the treatment or removal of ash trees located on their property.

What kind of trees will be replanted on streets and in parks?

The Town no longer plants ash trees. We will carefully choose the type of tree to be planted based on the tree's function, the intended location and soil conditions. The tree may need to be replanted in another location in the
community due to changes in underground utilities and surroundings. Residents will be informed of these relocations.

Can I choose the type of replacement tree, or what type of tree will be planted?

The replacement tree will be chosen by the Town from a pre-determined list according to specific site conditions.

Can I keep wood from my tree after it has been removed?

No. The wood from Ash trees must be disposed of in accordance with CFIA (Canadian Food Inspection Agency) Regulations.
