DESCRIPTION OF NATURAL HABITAT AND ECOSYSTEM(S) IT INVADES
The plant originally came from the wetlands of Eurasia. The ecosystem that it invades is just the wetlands. Invasive Phragmites is found in all of the lower 48 states in the United States and in all Canadian provinces and the Northwest Territories. It has not been found in Yukon or Nunavut. In Ontario, it has been identified across the southern part of the province with scattered occurrences as far as Georgian Bay and Lake Superior.

HOW INVASIVE SPECIES MIGRATES TO NEW AREAS
Phragmites spread by their seeds coming out of the top of the plant, then the seeds are blown to the ground and the start growing again and again like dandy lions. Phragmites produces up to 2,000 seeds per seed head per year. While seed spread, recent research has revealed that Phragmites spreads to new areas predominantly through seed dispersal.
Invasive impact (negative, positive)
Some birds, such as yellow throat, marsh wren, salt marsh sparrow and least bittern roost in Phragmites. Red-winged blackbirds and some wading birds have been documented to nest in the phragmites.
Efforts to control invasive species
To prevent the further spread and introduction of this unwanted invader in the province, Ontario has regulated invasive Phragmites as restricted under the Invasive Species Act.
