Sagittaria (Sagittaria platyphylla) is one of Australia’s worst weed species and listed as a Weed of National Significance (WoNS). Unfortunately it is now present in the NT.
Although seemingly small and innocent, this pretty ponded plant has the potential to infest and clog wetlands, displacing native plants and animals and altering water flows. Its small, light, pepper-like seeds can be spread by waterbirds, animals or humans.
The weed recently turned up in Darwin and Katherine nurseries incorrectly labelled as another species ‘Melon sword’. The resulting plant recall has determined the plant was also sold and distributed through the public approximately 10 years ago…… it could be in your back yard pond!
We are putting out a request for anybody who may have seen this plant, in their backyard pond, at a friend’s BBQ, fishing or hunting in the wetlands or at the Town Lagoon to please get in contact with Dhimurru who will in turn contact the NTG Weed Management Branch for its removal and destruction.
Please contact Luke at Dhimurru on 0499 037 753 or NTG Weed Management Branch on 8999 4567
Your assistance is very much appreciated
