Impacts: 

Crowds out native species. thickets displace native wetlands plants, alter hydrology and block sunlight to the aquatic community. Changed gene pool/ selective loss of genotypes
Ecosystem change/ habitat alteration
Modification of successional patterns
Monoculture formation
Negatively impacts agriculture
Reduced native biodiversity
Threat to/ loss of endangered species
Threat to/ loss of native species

Source? likely to be reintroduced: 

The risk of introduction of P. australis into the relatively few regions where it is not already present remains quite high. Availability via the internet makes deliberate introduction feasible (Kay and Hoyle, 2001) and while introduction in crop seed is not especially likely, the mere abundance of the weed and the variety of uses to which it is put mean that there is always a risk of accidental contamination of various types of produce or container.

Info Blurb: 

Crowds out native species. Thickets displace native wetlands plants, alter hydrology and block sunlight to the aquatic community. Introduced as ballast or packing material. Intentionally planted for erosion control and shoreline stabilization.
