Consult article 5.16.9 of By-law 720 hereafter which establishes standards aimed at limiting and controlling the spread of the emerald ash borer throughout the territory of the City of Beaconsfield:

5.16.9    Exceptional measures concerning ash trees

No ash tree may be trimmed, pruned or felled during the designated period between May 31 and September 1, with the exception of a dangerous tree, or a tree located in a construction area for a new residence or the enlargement of an existing residence only.

Notwithstanding the preceding, and section 3.2.1 of the By-law concerning permits and certificates and subject to the application of this section, an ash tree with a trunk diameter of less than 15 centimetres measured at 1.5 metres above the ground may be felled without a certificate of authorization.

Subject to the application of section 5.16.4, any request to fell an ash tree must meet the following conditions:

  1. The inspector shall point out any ash tree infested with the emerald ash borer and identify the tree by means of the visible logo “A”.
  2. To allow identification of the infestation, the owner of an ash tree must put at the disposal of the inspector, on the site of the tree felling, at least 2 sections of branches with a minimum length of 75 cm, a diameter of between 5 cm and 7 cm, located in the upper part of the crown and on the side of the tree exposed to the southwest. The inspector shall proceed with the debarking of the branches put at his disposal, and of any other branch which he deems necessary to determine the presence of an infestation.
  3. Any ash tree located within a radius of 100 metres of an ash tree infested with the emerald ash borer is automatically placed under quarantine, within a circular zone with the infested tree as the central point.
  4. The City will send, to each owner or occupant of a lot within the quarantine zone, as soon as possible, a notice to the effect that any ash tree located on their lot is subject to this by-law.
  5. Any ash tree located within the quarantine zone must be felled, or treated with a product approved or authorized by a Canadian governmental agency and applied in accordance with the manufacturer’s guidelines within 60 days of the issuance of the quarantine notice by the City.
    1. In the case of a felling, should the notice be issued during a period when felling is prohibited, the 60-day deadline may be extended until October 30 of the year in progress. The owner of the tree must disclose the name, address and telephone number of the contractor who will carry out the felling.
    2. In the case of a treatment with an approved or authorized product by a Canadian governmental agency, the owner shall provide the City with a proof of treatment of the ash trees placed in quarantine. This proof of treatment must be provided to the City within 15 days following the treatment. If a treatment must be repeated, proof of treatment must be provided to the City within 15 days following the second treatment.
  6. It is forbidden to store ash wood within the boundaries of the City unless it is used for firewood. In this case, the property must be equipped with a solid fuel burning stove or fireplace in compliance with applicable regulations.
  7. It is forbidden to plant, grow or cultivate an ash tree from a seed, a seedling or any other method. Anyone who owns, manages or tends a lot located within a quarantine zone is also prohibited from allowing an ash tree to grow on that lot, whether that tree grows from a seed, a seedling or a sapling, without following the procedures set out above.
  8. In the case of a property with one or several ash trees, the owner may fell a maximum of 4 ash trees per year. In the case of a property with several ash trees, the felling of up to one-quarter of the ash trees on the property will be authorized per year. The provisions in terms of issuing certificates apply and each felled tree must be replaced.
  9. Any felled tree (infested or not) must be replaced by a tree other than an ash. The replacement tree must have a minimum height of 1.5 metres from the ground. This provision does not apply to trees with a diameter of less than 15 cm measured at a height of 1.5 metres above the ground.
  10. Disposal of the following materials will not be accepted by the City during the period when felling is prohibited:
    1. Firewood;
    2. Trees;
    3. Nursery materials;
    4. Saw logs;
    5. Wood packaging, pallets and dunnage;
    6. Wood, bark or wood residue resulting from shredding operations of all species of trees.”
  11. Any dead ash tree must be felled within six (6) months following its death.

 

Consult all provisions of Zoning By-law 720.

 


Treat Ash Trees to Save Them

Frnes

 

All ash trees are threatened.The most economical solution is to treat them, otherwise they will have to be cut down (Mandatory permit application request available online).

A concerted effort by the citizens with the City will:

  • Ensure the value of all properties: trees are an added value that represents up to 18% of your property value
  • Preserve our urban forest
  • Save the canopy
  • Protect air quality
  • Reduce water runoff and flooding
  • Reduce heating and cooling costs

STRATEGY TO FIGHT THE EMERALD ASH BORER - 2018 ASSESSMENT (March 2019)

 


International Authority on Forest Ecology Underscores the Excellence of Beaconsfield's Program

Dr. Daniel Kneeshaw, an independent international authority on forest ecology, has commended Beaconsfield on the excellence of its proactive emerald ash borer management strategies.

Dr. Kneeshaw says that Beaconsfield's plan highlights the City's concern for protecting the environment. He added that its dual strategy of using a biopesticide to treat large trees, while felling small ashes and replacing them with a variety of species guarantees the future of Beaconsfield's urban forest, preservation of our living environment and maintenance of our property values.

This message of support from a Doctor of Forest Ecology and a Professor of Biology at the Université du Québec à Montréal (UQÀM) is particularly important, as Dr. Kneeshaw is an acclaimed expert in ecology and mixed forest silviculture. His research focuses on sustainable forest management, forest dynamics following disturbances, tree mortality and the impact of climate change on forest dynamics.

Dr. Kneeshaw has reviewed Beaconsfield's EAB Management Program in the context of an ash borer infestation raging across North America. Some 100 million ash trees have been killed by ash borers over the past decade.

The professor found Beaconsfield's strategy particularly commendable. He mentioned that many governments merely respond to environmental problems. "Beaconsfield's ambitious proactive measures clearly merit our admiration'' he noted.

Dr. Kneeshaw mentioned that urban forests have many high-value functions in the community, such as reducing runoff after downpours, diminishing heat, improving air quality and boosting property values. It would cost many millions to find replacements for all these benefits. He added that a recent US study showed the massive loss of trees to ash borers also led to the premature death of vulnerable persons.

"In addition to all the other services provided by trees, this particular benefit for our own longevity demonstrates the importance of acting now to maintain our urban forest canopy," Dr. Kneeshaw said.

He also applauded the excellence of Beaconsfield's strategy, based on a dual approach of replacing small trees and protecting large ones. He explained that small trees make a very minor contribution to the canopy, while large ones play key roles in this structure and deliver a multitude of other benefits.

 

Biopesticides: The Right Decision

Dr. Kneeshaw believes the decision to use biopesticides is the best choice for maintaining the benefits of these trees and ensuring the well-being of residents.

"This biopesticide does not kill ash borers directly. Rather, it impairs their development by preventing larvae from moulting and thus reproducing. The biopesticide's action is specific to insects living in the injected tree. Since ash trees are pollinated by the wind, there should be very little impact on insects attacking other trees," said this university researcher and international authority on ecology and silviculture.

Dr. Kneeshaw added that the selected biopesticide has been approved by the Organic Materials Review Institute for use in organic farming.

Daniel Kneeshaw is also pleased with the help that Beaconsfield has offered residents in obtaining a low treatment cost. This will encourage their participation, which is essential, since most of Beaconsfield's ash trees are on private land.

Dr. Kneeshaw also emphasized the need to diversify the urban forest to enhance its resilience, just like a diverse investment portfolio protects an investor against market swings.

"At the present time, the ash borer is the biggest threat. But invasive species could eventually appear, as in the past thousands of elms were killed by Dutch elm disease. Species diversification is a key factor in maintaining a strong and healthy urban forest," he concluded.

These observations by an international expert are particularly important as they confirm the appropriateness and necessity of Beaconsfield's efforts to preserves its environment and quality of life.

Ash Tree Identification Program on Private Property

As part of its action plan to fight the emerald ash borer, the City of Beaconsfield has inspected ash trees on private property during the summer

Students hired by the City have visited residences to compile an inventory of ash trees in the community. This inventory will help to better understand and predict the extent of the damage that this pest has the potential to inflict.

As a citizen, you can help to prevent an infestation:

  • To protect the health of your ash trees, visit the manufacturer of TreeAzin, a biopesticide, at bioforest.ca for a list of service providers licensed to apply the product;
  • For a health assessment of your ash trees, visit the Société internationale d'arboriculture website at siaq.org to find tree specialists.
  • Do not move ash wood, firewood, logs, branches, nursery stock, chips or any other form of ash wood. 

1. What is the Emerald Ash Borer?

The emerald ash borer is a highly destructive invasive beetle that attacks all species of ash trees and typically kills them in 2 - 3 years. It is a metallic green wood-boring insect of about 1 - 1.5 cm in length. It was confirmed as present in the area of Montreal in the summer of 2008. It has killed a large number of ash trees in North America and poses a major economic and environmental threat to urban and forested areas across Canada and the United States.

2. Where does it reside?


Its larvae bore tunnels under the bark to feed on inner bark tissue. The tunnels cut the flow of nutrients and water to leaves, causing the tree to die.

 

 

 

 3. How has it spread?eab bark

This invasive species which came in wood packaging from China, has now spread into areas of Ontario and Quebec as well as 15 states in the USA. The main way that it spreads is from tree to tree that are relatively close but also when ash tree fire wood is transported from region to region, the EAB will move and contaminate a new area.

 4. How do I know if I have an Ash tree on my property?
 
Ash trees are commonly found in streets, parks, and forests in the Montreal area. Ash trees are typically large trees reaching up to 30m tall at maturity.

Branches and leaves grow in an opposite pattern. Where one leaf or branch emerges, another grows directly opposite. Leaves are typically 5 to 15 cm long and compound with 5 to 11 leaflets. Leaflets have either smooth or toothed margins (edges).

Ash seeds hang in clusters of single, oar-shaped seeds and are often shrivelled. Clusters typically stay on the tree until late fall or early winter.

Young trees have smooth, light grey bark. Older trees have furrowed bark with a diamond shaped ridge pattern.

5. What should I be looking for?

Top branches of ash trees usually die off first. Trees can lose half their branches in a single year. Once larvae finish feeding under the bark, they mature into adult beetles that chew their way out of the tree.eab barkS-shaped grooves and D-shaped exit holes 3.5 – 4 mm wide caused by adult beetles (Photo: courtesy Troy Kimoto, CFIA)

Look for the following signs:

  • Loss of leaves and dead branches in the upper part of ash trees.
  • Unusually thin tree crowns
  • Branch and leaf growth in the lower part of the stem where growth was not present before
  • Long shoots growing from the trunk or branches
  • Unusually high woodpecker activity
  • Evidence of adult beetle feeding on leaves
  • Bark splitting, S-shaped grooves under the bark filled
  • Small D-shaped emergence holes
  • Exit holes 3.5 – 4 mm wide caused by adult beetles

6. Is there anything that can be done to prevent an infestation?

 
The Neem tree produces organic compounds that have been used in India for centuries as an effective way of protecting crops from insect pests. Now, this tropical broadleaf evergreen has been enlisted to help fight the emerald ash borer.
Using extracts from the Neem tree seed as a key ingredient, scientists from Natural Resources Canada worked collaboratively with BioForest Technologies Inc. to develop and commercialize a botanical insecticide called TreeAzinTM.

TreeAzinTM was specifically developed to control invasive wood boring insect pests and it is particularly effective against invasive pests like the emerald ash borer when used as a protective method on lightly infested trees.

7. What is TreeAzin?

Recently registered for use across Canada, TreeAzinTM allows for the treatment of urban trees in the early stages of an infestation.

The TreeAzinTM formulation contains a natural product called Azadirachtins, originating from Neem tree seeds. The insecticide interrupts insect larval moulting occurring under the tree bark. The compound significantly reduces larval growth, development and feeding, and also reduces fertility and egg viability when adults feed on the foliage of treated trees.tree azin nrcSystemic injection of TreeAzin to protect an urban ash tree from the emerald ash borer (Photo: Natural Resources Canada)

Researchers are confident that trees that are highly valued by homeowners and urban foresters can be effectively protected using this technique while other methods of control are developed.

Scientists from Natural Resources Canada's Great Lakes Forestry Centre and BioForest Technologies also jointly developed the injection system to deliver the insecticide. The system consists of pressurized canisters which are connected to the tree in a manner similar to an intravenous system. Once connected, the canisters release the insecticide under the tree's bark and directly into the tree's conductive tissues, and it moves upwards with the flow of water and nutrients.

Because TreeAzinTM is injected directly into the tree, it negates any potential human or environmental exposure, thus strongly mitigating any risks. Tests have shown that azadiracthins have generally very low toxicity to mammals, birds and other non-target organisms, which also enhances its suitability for use in urban and environmentally sensitive areas.

For more information on TreeAzinTM, please visit the manufacturer's website at bioforest.ca

No company is commissioned by the City to make door to door sales or visits.

8. Is TreeAzin a permanent solution?

TreeAzinTM can be very effective at controlling EAB infestations, but injections need to be applied between the months of May and the end of August. TreeAzin™ does not guarantee the survival of the tree and must be applied every 2 years, depending on tree health and EAB populations at the time of injection.

9. What can I do to contain an infestation if I see one?

  • Learn about the origin and type of your firewood and buy and burn only local firewood
  • Do not move any ash wood, firewood, logs, branches, nursery stock, chips or any other type of ash outside of the island of Montreal.
  • Do not dispose of tree branches (all tree species) in the garbage. In order to comply with the Ministerial Order on the EAB, the City will no longer pick up branches (all tree species) and green waste with the regular garbage collection.

10. Who should I call if I see an EAB on a tree?

  • For a city tree: call Beaconsfield Public Works at: 514 428-4500
  • For a private tree: contact Urban Planning 514 428-4430 for the tree permit request.

11. What should I know if I want to cut down an ash tree?

Ash tree felling request can be done online at no cost. CLICK HERE.

All requests concerning the felling of trees will now be analyzed in the following manner:

  • Following the deposit of the request, the City inspector will make a visual inspection. If it is an ash tree, the owner must, at his expense, hire a pruner. The pruner is required to provide the inspector with two branches of 5cm to 7cm diameter and a length of at least 75cm, located in the middle of the crown of the tree.
  • Should the inspector notice an infestation, the tree may only be felled between October 1 and March 15 of next year. The City inspector will mark the tree with the abbreviation "A".
  • In the case of an ash tree, the owner must mandatorily divulge the name and address of the entrepreneur who will proceed with the felling of the tree.
  • The branches and trunk of the infested tree are the sole responsibility of its owner. Their disposal must be carried out according to the ministerial order, namely:
    • The displacement of wood is authorized between October 1 and March 15.
    • The chipping of wood is authorized on the condition that the chips produced do not exceed 2.5cm by 2.5cm in maximum surface, on at least two facings.
    • Every ash tree that is felled must be replaced by a tree at least 1.5 meters high.
  • The City, via Public Works, will no longer accept between April 1 and September 30 of each year:
    • Firewood
    • Trees (except branches of a diameter of less than 15cm)
    • Nursery stock
    • Logs
    • Timber
    • Packaging timber, wood pallets, ship borne tonnage
    • Wood or bark or wood chips of any kind of tree
