TRCA Notification: Invasive Species Management at Arsenal Lands

By July 18, 2023Parks, Resources, Ward 1

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:
