Invasive Phragmites is a perennial grass that has been damaging ecosystems in Ontario for decades. It is an aggressive plant that spreads quickly and out-competes native species for water and nutrients. While it prefers areas of standing water, its roots can grow to extreme lengths, allowing it to 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.
What can I do?
Everyone can help to win the battle against alien invasive species. Here are some ways you can help:
--Professional help is recommended. The most effective method is a three-step combination of spraying with herbicide, mowing and controlled burning repeated over three years or until the patch is eradicated.
--Dispose of yard waste properly. Dumping yard waste in natural areas can introduce alien invasive species that will thrive and spread.
--Clean your shoes or bicycle tires when moving between designated trails in different areas. Invasive plants are often spread accidentally from seeds stuck in treads.
