An invasive species is a plant, fungus, animal, or insect that is not native to an area. It spreads, competes with native species for resources, and disrupts local ecosystems. There are invasive species in Niagara Falls. Check your trees, gardens, and ponds, do your research before buying plants or seeds, do not release aquatic pets, and always buy local firewood when camping.
Become familiar with invasive species by visiting Ontario websites in our resources section. See photos, fact sheets, and learn about what you can do about different invasive species. This is not a complete list:

Phragmites
Public notice - Phragmites spraying Warren Creek Water Course

Why this is important
Phragmites is a fast-spreading invasive plant that threatens native ecosystems, reduces biodiversity, and obstructs recreational areas. This spraying is part of a broader ecological restoration effort.
Spraying details
- A licensed contractor will apply an approved herbicide under strict environmental guidelines
- All necessary precautions will be taken to protect surrounding wildlife and water sources
- Signage will be posted at all entrances and along affected areas.
We appreciate your understanding and cooperation as we work to restore the natural beauty and health of Fernwood Park.

Pilot project: Herbicide spraying to control invasive phragmites
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

Phragmites control FAQs
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.
