Ontario is home to many invasive species that threaten forests, wetlands, waterways, and agricultural lands across the province. The St. Clair Region Conservation Authority (SCRCA) watershed is no exception, with non-native species posing significant risks to local ecosystems and biodiversity.
Invasive Phragmites (Phragmites australis) is one of the most visible and widespread invasive species in the St. Clair Region. This highly invasive reed spreads aggressively, can reach heights up to 5 metres, and can form extremely dense stands of up to 200 stems per square metre. If left unmanaged, Phragmites can degrade natural habitat, outcompete native plants, increase fire risk, and limit recreational access to affected areas.
To support on-the-ground action, the SCRCA has launched a cost-sharing program to help local landowners control and reduce Phragmites on their properties throughout 2026. Through the program, the SCRCA will cover the cost of the required control measures and equipment, while participating landowners will be responsible for costs associated with a licenced exterminator (approximately $50/hour).
“Invasive species like Phragmites can quickly overwhelm natural areas if left unmanaged,” said Jeff Sharp, Manager of Conservation Services at the SCRCA. “This program provides the tools and support they need to manage Phragmites on their property and make a real difference for the health of our watershed.”
Landowners who have Phragmites on their property and are interested in reducing or eradicating this invasive species can contact Jeff Sharp, Manager of Conservation Services at [email protected] or (519) 245-3710 Ext. 217.
This project is being undertaken with support from the Invasive Species Centre and in partnership with the Invasive Phragmites Control Centre and the Ausable Bayfield Conservation Authority.
In recognition of Invasive Species Week, taking place February 23rd to March 1st, the SCRCA encourages residents to learn more about invasive species and available management options. A valuable resource for more information is the Invasive Species Centre (www.invasivespeciescentre.ca).
Invasive Phragmites are a growing problem across the St. Clair Region and Ontario. This aggressive reed is commonly found along shorelines, wetlands, roadside ditches, and agricultural areas.
