Saint-Laurent commissioned the forest engineering firm Trame-Verte to update existing data on the tree heritage, assess the condition of the trees and complete the inventory.

Inventory visits

Trame-Verte technicians will be making home visits to carry out an inventory of trees on private property.

These visits take place Monday to Friday between 7 a.m. and 7 p.m. and last only a few minutes. 

Your cooperation is required to give them access to your back and/or side yard. If the yard is accessible, the technicians will not ring the doorbell before the visit. 

However, if you are absent during the visit and your yard is not accessible, a notice will be left so that you can make an appointment for a future visit.

• The presence of a tree near a building can reduce air-conditioning requirements by up to 30%.

• A mature tree can capture an average of 7,000 suspended particles per liter of filtered air.
• One tree can supply the daily oxygen ration of 4 people.

Frequently asked questions

How does a technician visit work?
Trame-Verte staff will inspect the tree or trees on your property. They will collect the data needed for the inventory and leave the property to go to the neighbouring property. Data collection will take about 2 minutes per tree. The on-site technician will not perform an in-depth diagnosis of your tree, but rather a summary assessment of its state of health. 

What happens if I’m absent during the visit?
If your yard is accessible, you don’t need to be present during the technician’s visit. However, if your yard is padlocked or inaccessible, the technician will leave you a notice of visit in the form of a door hanger, so that you can make an appointment with him for a future visit.

What type of data will be collected during visits?
The technician will collect data such as tree species (genus, species and cultivar), DBH (trunk diameter at 1.4m from the ground), location (front yard, side yard, back yard), condition (tree or stump) and whether the tree is good, average, weak (dying) or dead.

What will the data collected be used for?
The data collected will enable the borough to : 

• calculate the canopy index
• monitor the state of the Saint-Laurent wooded areas in the context of climate change
• pursue actions in favor of biodiversity, such as planting species that are poorly represented on the territory
• implement actions to reduce heat islands, retain rainwater, etc.

 
Can I access the data collected?
Yes, to access the data collected, you must make an Access to Information request at a BAM office or by calling 311.
 
We’ve made a felling request on the city’s website. Will the technician be able to tell me whether or not I’ll get a felling permit?
No. The technician is not mandated to evaluate the tree in the context of a felling certificate request or for any other request concerning its state of health. 
If you wish to follow up on a felling request, you can contact [email protected] or visit the permit counter at 777, boulevard Marcel-Laurin, open Monday, Tuesday, Thursday and Friday, 8:30 a.m. to 12 p.m. and 1 p.m. to 4:30 p.m.
