WHAT IT LOOKS LIKE:
Erect robust semi-aquatic perennial.
WHERE IT GROWS & WHY:
Widespread and common throughout region.
Streams, swamps, lakes and local water-filled depressions, in fresh or slightly brackish water to 2m deep.
Salt tolerant. In shallow creeks, dense stands slow water movement and cause flooding of surrounding land during high flows.
MANAGEMENT/SIGNIFICANCE:
Vigorous, particularly during summer. A major weed of irrigation channels west of the guide area.
Useful to extract pollutants from waste or drainage water. Reduces evaporation from swamps or shallow lakes as plants shelter the water surface from wind.
Excellent habitat for waterfowl and frogs.
To reduce the size of cumbungi stands, cut plants below the waterline in autumn.
