Crimson shiner (fish)
Potential impacts: scale back native fish populations via predation on eggs and larvae, genetic impacts via hybridization, and introduction of parasites.
Oxygen weed (aquatic plant)
Potential impacts: dense colonies outcompete native vegetation, adversely have an effect on water high quality, and impede leisure actions resembling boating and swimming.
Nutria (mammal)
Potential impacts: burrowing and foraging behaviour impacts agricultural areas and will increase flooding dangers, unfold parasites and illness to people, pets and livestock, and might destroy coastal wetlands.

Flowering-rush (aquatic plant)
Potential impacts: can displace native riparian vegetation, kinds dense stands which influence industrial and leisure makes use of of shallow waters, and reduces habitat of native fish and will increase habitat for invasive fish.
Tree-of-heaven (terrestrial plant)
