Notice of upcoming invasive species treatment by Credit Valley Conservation (CVC). Treatment will involve the use of herbicides to reduce the number of invasive plants and their threats to the natural area.

The work will be taking place at Cawthra Park and will be targeting two different species of plants. Please see below for more detailed information:

• Target species: Japanese Knotweed
• Details: A small patch along the trail running along the east side of the park, adjacent to the houses. The area was treated in 2022 and any regrowth will be retreated this year. The area is just south of South Sheridan Way. Impacted residents will be notified by letter.
• Target species: Phragmites
• Details: Several patches near the entrance to the park off of Eight Street, on both sides of the pathway. This area was treated in 2022. Impacted residents will be notified by letter. An additional area will be treated in 2023, near the back of the community centre. Any plants present on the woodland side of the wooden boards will be treated this year, with any remaining plants treated once the boards are removed in 2024.

The treatment is scheduled for August 22^nd and 23^rd. As herbicides are being used, all work is weather dependent so the treatment days are subject to change. As per Ontario Regulation 63/09 under the Pesticides Act, signage will be posted at least 24 hours before treatment (no longer than 7 days prior), and will be removed 48 hours after treatment (no longer than 10 days after).

CVC will be using Roundup VisionMax (Glyphosate) which is sprayed using a handheld/backpack sprayer.

Crews will be working Monday to Friday from 8 a.m. to 4 p.m.

Notice of upcoming herbicide application by the Forestry Department through the use of Brinkman Living Infrastructure beginning Friday, August 11^th, 2023.

Chemical control will be completed at the following parks. See below for more details:

• Adamson Estate
  • Target species: Japanese Knotweed
  • Details: Re-treatment of the areas treated in 2022. This includes any plants present throughout the natural area. Flagging tape has been installed in these areas for the Contractors. They are expected to remove it following treatment.

The herbicide being used is VisionMax (Glyphosate) and is sprayed using a handheld/backpack sprayer.

Please note: The site will have notice signs 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. Treatment should be completed in 1 week, but may extend into further weeks as needed as the work is weather dependent.

TRCA strategically manages invasive plant species at specific restoration project sites throughout our jurisdiction. Working closely with their partners, TRCA follows best management practices including integrated pest management that uses a variety of preventative and non-chemical pest management strategies (e.g., continuous mowing to suppress growth, spading, solarizing, and composting) which aligns with TRCA’s Invasive Species Management Strategy. Depending on the severity of the infestation and the plant species, herbicide application is often the best management option that allows restoration of the landscape using native plant species.

This summer they will be applying herbicide to manage invasive Phragmites (Phragmites australis) in the Arsenal Lands (Closest Address: Lakeshore Dr E & Dixie Road, Mississauga, Small Arms Inspection Building) to achieve the larger objective of invasive species management throughout the Peel Region Parks. Using licensed applicators, these species will be treated with herbicide (Habitat Aqua – PCP #32374) following all applicable legislation. Standard regulatory signage will be installed in the treatment area before it occurs and will be removed once management efforts have been completed. Invasive control assessments and necessary adaptive management activities will occur in the coming seasons to further improve the site’s biodiversity.

Spraying will take place between July 24 and August 18. You can find a map of the spray sites below:
