Invasive Phragmites
Invasive Phragmites (European Common Reed) is an invasive plant that has been damaging ecosystems in Ontario for decades, particularly wetlands and beaches. Invasive Phragmites is a perennial grass that spreads quickly and out-competes native species for water and nutrients. It releases toxins into the soil from its roots that hinder the growth and kills surrounding plants. It prefers areas of standing water; however, its roots can grow to extreme lengths which allows it to also survive in relatively dry areas.
Impacts of Invasive Phragmites:
crowds out native vegetation, thus resulting in decreased plant biodiversity;
generally provides poor habitat and food supplies for wildlife, including several Species at Risk;
grows very quickly thereby causing lower water levels as water is transpired faster than it would be with native vegetation;
increases fire hazards as stands are composed of a high percentage of dead stalks; and
can affect agriculture, cause road safety hazard and impact recreational activities such as swimming, boating and angling.
