Impacts: 

Forms dense mats that block sunlight and reduce oxygen levels. forms chains of leaves that run together to form thick mats on the surface of the water. These mats restrict oxygen and light availability causing death of the primary producers and disrupting the aquatic food chain.

Source? likely to be reintroduced: 

S. molesta is spread within an aquatic system by the movement of plants by wind, water currents, floods and animals. Birds, capybara, hippopotamus and waterbuffalo have all been documented to spread Salvinia between waterways. Spread between aquatic systems is assumed to be mainly by humans moving plants intentionally (as ornamentals), unintentionally as a hitchhiker on boats, or in shipments of aquatic plants and fish.
