Suspected water weeds, like water hyacinth, that are sold via internet trading sites should be reported to the Department of Agriculture and Food.
Users of online markets are warned to keep watch for sales of illegal water weeds and to report any sightings to the Department of Agriculture and Food.
There has been a proliferation of sales of declared weeds, which pose a risk to the environment and the agriculture and food sector, since the rise of the internet to trade goods.
Regional invasive species leader Tim Thompson said the most recent case was a person selling a pond full of water hyacinth.
“Some people are not aware that the weeds they are selling have been banned for years and years, while others are very much aware of the action they are taking,” Mr Thompson said.
“People may think that they aren’t creating a risk, as they’re selling weeds to people who will keep it in their ponds – but the weeds often get away.
“Sometimes the weeds are spread by ducks and other fauna, while the simple act of a seed on a shoe can transfer the weed far and wide.”
Recent apprehensions have involved the sale of water hyacinth, sagittaria and salvinia, all of which spread quickly in ponds, swamps and drains killing native flora and fauna.
The department is currently working with local government councils in Melville, Baldivis, High Wycombe and Rockingham to eradicate water weeds that have been dumped in local waterways.
Any suspect sightings of water weed sales on the internet, at markets or in the community can be reported via the department’s Pest and Disease Information Service by freecall 1800 084 881 or email info
