Aquatic weeds
Declared noxious aquatic weeds include Ludwigia longifolia (Longleaf Willow Primrose), Hygrophila costata (Hygrophila), Salvinia molesta (Salvinia), Eichhornia crassipes (Water Hyacinth), Sagittaria species (Arrowhead), Pistia stratiotes (Water Lettuce), Alternanthera philoxeroides (Alligator Weed), Cabomba species and Gymnocoronis spilanthoides (Senegal Tea Plant).
Egeria densa (Dense Water Weed or Leafy Elodea) is a class 5 noxious plant, which means the sale of plants is prohibited.
Aquatic weeds are usually described as submerged, floating or emergent, although some plants can combine these features. Submerged weeds are the hardest to treat and have the greatest potential for damage to natural and human use of waterways.
The file below contains images of common noxious aquatic weeds. For additional information on aquatic weeds or native look alike plants contact the weeds office at council.
Please report possible occurrences of aquatic weeds to council.
