Salvinia Molesta (Salvinia)
Salvinia is a fern from South America and is declared a noxious plant throughout Australia. The leaf structure gives buoyancy to the plant allowing it to float on the surface of the waterway.
This plant, under the right conditions has the ability to double the area it covers in 5 - 10 days.
Salvinia is capable of choking wetlands, killing fish, reducing water quality and harbouring disease-bearing vectors, this weed can be treated chemically but the preferred method is mechanical or manual removal
