Parc Jean-Drapeau
PAMV Project Preparatory Work

PAMV Project Preparatory Work

To prepare the site for the building of a new natural amphitheatre and central concourse starting in the spring of 2017, the Société du parc Jean‑Drapeau is currently conducting tree cultivation and maintenance work on the south sector of Île Sainte‑Hélène.

Work to be done on trees in this sector

  • Pruning
  • Transplanting
  • Cutting down
  • Grubbing


February 13 to March 31, 2017
Monday to Friday 7 a.m. to 5 p.m.
Closed sector

Parc Jean‑Drapeau's commitment

Minimize the impact on the ecosystem

  • The SPJD is committed to offsetting the cut all of the trees that are removed in conjunction with this project. Thus, for any tree that is cut down, a tree will be planted elsewhere in the Parc over the next 5 years.
  • We are giving a second life to trees that are removed by transforming them into wood chips which will be used as mulch to protect the Parc's wooded areas.

Characteristics of the trees being removed

  • Based on an analysis conducted by forestry engineers, 71% of the removed trees have a low preservation value and 11% have no preservation value at all, which means these trees are diseased or dead.
  • All of the trees in the sector being worked on were planted in the 1990s, so no tree being removed is older than 25 years of age.

PAVM: enrich the biodiversity

The SPJD will take the opportunity to increase its positive impact on the Parc's ecosystems. To do so, several hundreds of tree species will be planted in this new development, thus enhancing the biodiversity and the potential of quality wildlife habitats. The new landscaping will be composed of indigenous tree species, shrubs, native grasses and ecological seed plantings.

Biodiversity is the variety of life and the dynamics of its interactions. It is the diversity of plants, animals and micro‑organisms, as well as the genetic diversity in species and the diversity of ecosystems. It is all forms of life, along with their interactions with each other and their particular life environment. Biodiversity protection at Parc Jean‑Drapeau remains a priority and is part of a broader vision on sustainable development.

Frequently Asked Questions

What does this tree cultivation and maintenance work consist of?

The tree cultivation and maintenance work includes pruning, transplanting, cutting down and grubbing of trees on which the work is done in order to lay the groundwork for the arrival this spring of the general contractor for the PAMV (Development and Enhancement Plan) construction site.

All trees removed from the site were planted in the 1990s, thus none of the trees being cut down are older than 25 years of age. Moreover, based on the report of the forestry engineer assigned to this project, 71% of these trees have a low preservation value, and 11% have no preservation value at all, which means that are dead or diseased.

Why are you cutting down trees?

We need to get the site ready for the carrying out of the Development and Enhancement Plan on Île Sainte‑Hélène, which includes a natural amphitheatre and completely renovated central concourse that is able to accommodate 65,000 visitors. In the new plan, the vegetation will be spread out differently, but it will still be highly present. We are taking the opportunity to remove dead or diseased trees in this sector.

What types of trees are you going to cut down?

The main tree species to be cut down are as follows:

  • Norway Maple / exotic and invasive species
  • Colorado Spruce / exotic species, not very representative of the region
  • Ash / vulnerable to the emerald ash borer
  • Siberian Elm / exotic and undesirable species
  • Other species
How do you determine the preservation value of a tree?

The preservation value is determined on three components based on the SIAQ (Société internationale de l'arboriculture du Québec) method; the components are the diameter of the tree, the species aspect and the health condition of the tree. It is worth noting the diameter of the tree stems is the variable which affects the preservation value the most.

How many trees in all do you have at the Parc?

The tree count was done for trees that are more than 10 centimetres in diameter. We estimate there are about 17,700 trees on the two islands.

What offsetting measures will be implemented?

As part of Phase 1 of the PAMV, about 550 new trees will be planted on the project site. We will then replant them at the Parc to offset the negative outcome of the trees that are being removed.

What are you going to do with the trees that are cut down?

All of the cut branches will be transformed into wood chips which will then be used as mulch at various places in the Parc to protect the wooded areas.

What impact will the project have on wildlife?
  • Snakes: Measures will be taken to avoid the migration of snakes inside the construction site area. If snake species are found during the construction work, they will be picked up and released into their natural environment.
  • Birds: The tree cultivation and maintenance work will be done outside the dates of the nesting period.
Will this area of the Parc be closed during the forestry work?

For safety reasons the areas of the construction site where work is being conducted will be closed off and secured by the entrepreneur to prevent passers‑by from being able to enter the premises. All the necessary measures will be implemented to ensure the safety of the public and workers.

Why are you going to cut down the trees so soon in relation to the start of the work project?

We need to do the tree cultivation and maintenance work before spring, so that the work will be over before the birds' nesting period at the Parc.

Why are you leaving the tree stumps exposed?

Since the next step in the project is the excavation when the general contractor gets there, it will be more efficient and less expensive for the contractor to completely excavate the ground, gathering up the stumps in the process.

How long is it going to take for the work to be done?

The contractor for the tree cultivation and maintenance work will be on site from February 13 to June 15, 2017. Pruning, cutting and grubbing works have been completed since April 30, 2017. Transplantation works will run until June 15, 2017. The general contractor will be starting work on the construction site in June, 2017.

Who is the contractor for the tree cultivation and maintenance work?

The contract was awarded to the Asplundh Canada ULC company, the leader in vegetation management in the province of Québec.
