Pest Weed ‘Parrot’s Feather’ Found in Riverland

Potentially dangerous aquatic weed ‘Parrot’s Feather’, also known as Myriophyllum aquaticum has been found in a backyard pond in Berri, in SA’s Riverland region.

The pond owner was shocked when she discovered the plant she bought more than 17 years ago was found to be a pest weed by the Berri Natural Resources Centre, who correctly identified and told her how to dispose of it.

Parrot’s feather can become a serious problem if it reaches natural waterways, competing with native plants for survival.

Natural Resources South Australian Murray-Darling Basin (SAMDB) District Officer Hannah Spronk decsribed the weed, saying “[it] produces dense tangled mats of plant material on the water surface that become a solid weed mass that are impenetrable for aquatic species.

“Infestations must be contained wherever possible to avoid further spread resulting from the movement of plant fragments,” she said.

Ms Spronk advised people to dispose of Parrot’s feather correctly by removing it and placing it in a black plastic bag, then leaving it in the sun to ’cook’ and dry out completely.

“After that, you can burn it, or once it’s completely dry and dead, you can put it in the red bin,” she said.

Parrot feather is proposed for declaration under the Natural Resources Management Act 2004, with prohibition on sale and movement throughout South Australia.
