Invasive species removals coming to parks and natural areas

We’re working to improve ecological health in our parks and natural areas by removing invasive plant species like buckthorn, Japanese knotweed, dog strangling vine and phragmites.

Removals take place throughout the year using mechanical and herbicide methods. The work for each site takes three to five days to complete, weather permitting. During removals, park facilities and most trails will remain open, however, we ask that you avoid marked work areas until signs are removed.

Dates for specific sites are added as they become available.

Background

Why we remove invasive species from parks and natural areas

Dog strangling vine, Japanese knotweed, buckthorn and phragmites are invasive species that are not native to Ontario. Invasive species crowd out native species, threaten ecological integrity of parks and natural areas and reduce habitat for wildlife. Removing both invasive species before they establish and spread protects our parks and natural areas.

There are some exemptions available to municipalities under the Pesticide Act that allow us to use pesticides. We assess our needs for pesticides on a case-by-case basis, and only use them for forestry and natural resource management where native ecosystems are threatened. We never use pesticides for cosmetic reasons.

How we’re removing dog strangling vine, Japanese knotweed ,buckthorn and Phragmites

We will use machinery and herbicide to remove buckthorn, Japanese knotweed, dog strangling vine  and Phragmites from parks and natural areas.

We assess our parks and natural areas regularly and in many cases, mechanical methods alone are not effective. Herbicide is chosen for its overall benefit to the natural area. These benefits include:

  • Less disruption to the surrounding plants and wildlife that machinery would cause
  • A better chance of preventing the plants from sprouting, lessening the chance of disturbing the area with further removals

Garlon™ RTU will be used to control the buckthorn. Arsenal® will be used to control dog strangling vine. .  Japanese knotweed and Phragmites are  controlled with  Roundup WeatherPro ®.

These products are registered for use in Canada and have been tested to ensure minimal risks to human health and the environment. Licensed applicators will apply Garlon™ ,Arsenal  or  Roundup WeatherPro ® directly onto stems of  invasive plants as appropriate. Using a targeted application means we will use less and protect surrounding plants.

For more information on Garlon™ , Arsenal® or Roundup WeatherPro ® visit the Canadian Pest Management Regulatory Agency’s (PMRA) website or download their app, Pesticide Labels, for on the go information.

Stay out of the work area when signs are present

Both Garlon™ , Arsenal® and Roundup WeatherPro ® have a low exposure risk to people and animals when used correctly however, the treatment zones are closed to pedestrians during herbicide application. Please avoid entering the treatment area until signs are removed.
