Public reports lead to invasive weed detection

Two new infestations of the invasive aquatic weed limnocharis have been found in Far North Queensland.

The infestations were found in a swamp at Mission Beach and a pond in Redlynch following reports from members of the public.

Tropical Weed Project Manager for Biosecurity Queensland, Mick Jeffery, said residents in Far North Queensland were recently asked to be on the lookout for limnocharis.

“Limnocharis causes serious environmental damage, overtakes native plants, and is a problem for farmers in parts of Asia, so we need to make sure we find every last infestation of limnocharis so it doesn’t become established in Queensland,” Mr Jeffery said.

“Community support for our recent campaign to track down any infestations shows that community involvement is the key to eradicating limnocharis.

“If limnocharis is still out there, we want to know about it,” he said.

Biosecurity Queensland received 29 reports from the public as part of the recent campaign, with two reports confirmed as limnocharis.

Mr Jeffery said the recent detections meant the search was not over yet.

“Sightings like these recent ones are crucial to our program to wipe out this invasive weed in Queensland,” Mr Jeffery said.

“Early detection means infestations are generally smaller, making them easier and cheaper to remove.

“These recent findings show that there could be more infestations in the north, so we’re asking residents to remain vigilant and report possible sightings.”

If you think you have seen limnocharis on your property make sure you don’t handle it or spread any seed.

Clean your footwear or any equipment and vehicles before leaving the area.

Take note of its location and report it to Biosecurity Queensland on 13 25 23.

Biosecurity Queensland will be at the Cairns Show from 19-21 July 2017 and the Tully Show from 28-29 July 2017 with live specimens of limnocharis.

Limnocharis is classified as a pest plant under Queensland legislation and it is a serious offence to introduce, keep or sell these weeds without a permit issued by Biosecurity Queensland.
