An invasive plant is expanding its territory in northern Ontario, prompting local communities to collaborate on methods to detect and manage it before it firmly establishes. The Junction Creek Stewardship Committee, based in Sudbury, recently organized a workshop in partnership with the non-profit organization Invasive Phragmites Control Centre. The workshop aimed to educate individuals on how to recognize invasive phragmites and prevent its spread.
Invasive phragmites, also known as common reed, have the potential to form dense stands that outcompete native flora and disrupt wetland ecosystems. Jayden McGleish, a field supervisor at the Invasive Phragmites Control Centre, highlighted the plant’s increasing presence in northern Ontario, including significant patches emerging in Sudbury.
The rapid growth of invasive phragmites can impede native plant species like cattails and bulrushes, creating obstacles for wildlife. McGleish expressed concerns about the challenges faced by turtles and frogs navigating through dense phragmites patches, leading to adverse consequences for local ecosystems.
Apart from ecological impacts, invasive phragmites can encroach on recreational areas by encroaching on shorelines and hindering access. Furthermore, the plant’s ability to grow through asphalt and disrupt drainage systems poses financial burdens on municipalities by necessitating repairs.
Although invasive phragmites are more prevalent in southern Ontario, sightings in northern regions, including Sudbury, Sault Ste. Marie, Timmins, and Thunder Bay, are becoming increasingly common. Erik Barr, a contract employee at Conservation Sudbury, emphasized the importance of proactive measures in containing the spread of the invasive plant within Sudbury.
Educating the public on distinguishing between native and invasive phragmites is crucial for monitoring and managing the plant effectively. Jaclyn Groom from the Junction Creek Stewardship Committee highlighted the need for public awareness, particularly regarding inadvertent transportation of plant material by vehicles and equipment along roads and railways.
Treatment of invasive phragmites was also addressed during the workshop, with Chuck Simpson, manual controls manager at the Invasive Phragmites Control Centre, showcasing the use of backpack sprayers and an herbicide called Timberline. The treatment process can achieve a high kill rate, although regrowth of some plants may occur the following year.
Overall, collaborative efforts among communities, environmental groups, and experts are essential in combatting the spread of invasive phragmites in northern Ontario and safeguarding the region’s biodiversity and ecosystems.
