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)
