Weeding out poisonous plants is a tough battle
FIRE is just one weapon in the arsenal of Ipswich weed fighters trying to kill outbreaks of common garden plants.
On the hit list are lantana, mother of millions, cat's claw creeper, Dutchman's pipe, white moth vine, Madeira vine and bitou bush.
Many garden-lovers embraced lantana, mother of millions, cat's claw, Dutchman's pipe and white moth as ornamental plants, but now they are out of control.
Queensland Parks and Wildlife Service South D'Aguilar senior ranger Andrew Kingston said lantana was a major target.
"Lantana shades out native species and changes the structure of the forest it invades, discouraging native animals. It also has attractive fruits that encourage dispersal by birds," he said.
"Lantana also can make the affected areas impenetrable to animals, people and vehicles.
"It is also poisonous to stock."
Mr Kingston said a range of weapons was needed to wipe out weeds.
He said QPWS was working with other government departments and the CSIRO to support scientific research to biocontrol weeds species and run trial programs.
"An active appropriate controlled burning program will help native plant species out compete many weed species," he said.
"Appropriate fires are ones lit when there is a high soil moisture content and the flame intensity can be kept relatively low."
Mr Kingston said a few simple steps by residents could make a huge difference.
"Know what plants are growing in your garden," he said.
"Buy plants that are not known to become invasive weeds, do not dispose of garden waste in the bush, remove garden plants that are known weeds and control weeds growing on your property."
- Bitou bush: Pretty yellow flowering bush often found in gardens.
- Rubber vine: Rapid spreading pink-flowered vine that drastically takes over the native flora.
- Lantana: Flowering bush found in most places.
- Mother of millions: Escapee from gardens originally from Africa and Madagascar.
- Cat's claw creeper: Pretty bush with yellow flowers found in many gardens. It grows along streams and creeks.
- Dutchman's pipe: Ornamental plant and a very invasive weed.
- White moth vine: A fruit-bearing perennial vine with white undersides on its triangular leaves.
