The burrs.

Spreads quickly along river systems.
This is an invasive weed from the Americas and spreads along river systems. It is mildly toxic when it is younger and may cause contact dermatitis in humans and livestock. This weed is already well established through river systems in WA and the Top End.

Just another reason to be vigilant that no river sand is brought onto your property and if you have riverine habitat on your property this is another one to be on the lookout for.
