What is Phragmites?
Phragmites is a highly aggressive grass which can grow up to six meters tall. Once established, it spreads underground through it's root system forming dense stands with up to 200 stems per square metre. Phragmites has spread beyond wetlands and can be found in ditches, ponds, and creeks through Southern Ontario. Phragmites can also spread via seed and root and have been known to even take over drier areas, such as beaches and dunes, as long as the root can reach water.
These stands replace open water, blocking wildlife movement, reducing biodiversity by replacing native plants and overtaking important habitat. Which will also impact recreational areas.
