Invasive Species

This initiative is being carried out in collaboration with the Niagara Peninsula Conservation Authority (NPCA), neighbouring municipalities, local partners, and the Invasive Species Centre, Invasive Phragmites Action Fund through the Ontario Ministry of Natural Resources (MNR).

The City of Niagara Falls is launching a pilot vegetation management project aimed at controlling and eradicating Phragmites australis (Common Reed), an aggressive invasive species that threatens local ecosystems and infrastructure.

Project scope

Herbicide spraying will take place at select locations across the city, including parks, road allowances, and naturalized areas identified as high-risk for Phragmites infestation.

Timing

Spraying will occur from mid-September to mid-October. All spraying activities are weather-dependent and may be rescheduled in the event of unfavourable conditions.

Why phragmites control matters

Phragmites spreads rapidly, displacing native plants, clogging waterways, and reducing biodiversity. This pilot project is part of a long-term strategy to restore ecological balance and improve public access to natural spaces.

Safety and compliance

• All herbicide applications will be conducted by licensed professionals
• Treatments will follow provincial and federal environmental regulations
• Signage and temporary closures will be posted at affected sites during spraying

Protect our wetlands: Stop invasive phragmites!

Why control phragmites

• Phragmites is an invasive plant that spreads quickly and harms native wetlands
• It blocks water flow, increases fire risk, and pushes out native plants and animals

Why spray now?

• Late summer to early fall is the best time to spray
• This is when the plant sends nutrients to its roots, making the herbicide more effective

Safe spraying tips

• Use only approved herbicides
• Wear gloves, goggles, and protective clothing
• Avoid spraying on windy days to prevent drift and unwanted treatment of desirable plants
• Get permits if spraying near water – Our contractor is licensed

What happens after spraying

• Stocks may be cut down, mulched or removed at a later time
• Monitor the area for regrowth and re-spray when needed. It is expected to take 2-3 treatments to eradicate the Phragmites.

Native plants will return over time! As Phragmites die off, more desirable and native plants will not be outcompeted.
