Project: Phragmites Detection and Removal

Scott Parker with Parks Canada tells us about the Phragmites Detection and Removal Project going on within the boundaries of the Fathom Five National Marine Park and the Bruce Peninsula National Park in Ontario.

What type of project is this? 

  • Education and outreach
  • Direct management (i.e., spraying and burning)

Why is Phragmites an issue in your area? 

Phragmites is perceived as a threat to the ecological integrity of the park and it requires active management to prevent establishment.

Experimental injection of horticultural vinegar into Phragmites rhizome. Results: it didn’t work as a method for managing Phragmites.

  • Early detection and removal (mostly with herbicide). Through active management we have prevented the establishment of Phragmites.
  • Prevention through education programs for this and other invasive species.

What are the funding sources for this project?

We use existing internal capacity and funds.

What are the goals and objectives for the project?

To maintain the parks in a Phragmites-free state.

What type of land does your project target?

National park land, including the coast of Lake Huron and interior waters.

Do you monitor the areas that you manage? If so, what does that entail?

Yes, we use directed surveys in high use areas and where invasion is most likely. In remote locations, we rely on opportunistic sightings.

What is the status of the project and are you seeing results?

The project is doing well. We have been able to detect and remove early colonizers.
