Impacts: 

can significantly alter habitats it invades by outcompeting native species, reducing water oxygen levels and blocking light. Altered trophic level
Damaged ecosystem services
Ecosystem change/ habitat alteration
Increases vulnerability to invasions
Infrastructure damage
Modification of hydrology
Modification of natural benthic communities
Modification of nutrient regime
Modification of successional patterns
Monoculture formation
Negatively impacts human health
Negatively impacts aquaculture/fisheries
Reduced native biodiversity
Threat to/ loss of endangered species
Threat to/ loss of native species
Transportation disruption

Source? likely to be reintroduced: 

often used as an ornamental. Escape from cultivation likely explains its introduction beyond its native range. Its ability to spread rapidly through vegetative means coupled with a high degree of phenotypic plasticity means the likelihood of establishment once the plant is released is high.

Info Blurb: 

Can form monocultures, altering habitat and reducing biodiversity. Negatively impacts aquaculture and fisheries. Often used as an ornamental. Escape from cultivation likely explains its introduction beyond its native range. Can spread rapidly vegetatively.
