• Weeds incur large financial costs to all land managers
• Weeds can greatly increase fire threats • Weeds degrade farming land and can
poison stock• Weeds block waterways, can increase
flooding risks and damage infrastructure
Weeds can completely change an entire landscape!

STOP!! do not
- garden waste holds seeds and other plant
material that spreads weeds to environmentally sensitive areas. Just
because its biodegradable does not mean it is good for the environment!
Please dump your garden waste / green waste into
creeks, drains or any other areas

Brazilian Red Cloak(Megaskepasma erythroclamus)
