Invasive species control using herbicide
Herbicide application to control Dog-Strangling Vine and Japanese Knotweed in natural areas will occur on various dates between June 8th – June 19th at Adamson Estate. Additionally, Lilly of the Valley, Common Burdock and Yellow Archangel will be treated between June 8th – June 19th at Cawthra Woods.
If any touch ups are needed the contractors will be returning between July 6th – July 17th.
Phragmites (Common Reed) treatment will also occur on various dates between July 27th – August 14th at Cawthra Woods and Park 510 (330 Indian Valley Trail).
If any touch ups are needed for phragmites control the contractors will be returning between September 8th – September 11th.
Contractors working on behalf of the City (Invasive Phragmites Control Centre) will be applying RoundUp WeatherPRO (Glyphosate) or Habitat Aqua (Imazapyr) directly to the plants using a handheld/backpack sprayer to minimize impacts to plants in the surrounding area. Habitat Aqua will only be used in wet areas and the City has obtained the proper permits to apply this herbicide.
Notification signs will be posted at all access points to the spray area at least 24 hours prior to treatment and will be removed no less than 48 hours after treatment. Timelines may be extended as needed depending on weather conditions.
This work supports the City’s Invasive Species Management Program and improves the health of natural areas across the City.
