(Phragmites australis australis)
Invasive Common Reed or Phragmites is a type of grass native to Eurasia that has invaded all continents excluding Antarctica. It is fast-growing and large, reaching heights of up to 5 metres or 15 feet! It was first discovered on the east coast of North America, and has since spread inland and northward as far as Thunder Bay. The Eurasian subspecies is invasive, but there is a native subspecies in North America (Phragmites australis americanus) that is adapted to local ecosystems and is not a threat to native species.
Invasive Phragmites is widespread across southern Ontario along roads and ditches, wetlands, beaches, marshes, and other low-lying, wet habitats. In northern Ontario, Phragmites stands are generally smaller and scattered, but are still a threat to native species and biodiversity.
