Hi Krystle,
The Lama Lama website states: Our priority weeds for management are rubbervine, sicklepod, lantana, gamba grass, giant rats tail and olive hymenachne. confirming the presence of the weed.
I am not 100% sure about where invasive weeds would otherwise be recorded. However, I did find this Management Statement by Queensland Parks & Wildlife Service
Hope this helps.
Kind regards,
Evelyn
