Development and enhancement of the marsh sector

This marsh, the mountain’s last natural wetland, is an ecological hub with exceptional biodiversity in an urban environment. The marsh sector and its environment are essential to maintaining balance and biodiversity in Mount Royal Park, as they play a leading role in the catchment and retention of stormwater.

To ensure biodiversity in the park, plants native to this ecosystem will be introduced next spring

Where?

What? 

• Development of a network of paths
• Creation of walkways and lookouts
• Introduction of plants native to this type of ecosystem
