The plants identified here have the potential to cause significant damage to Western Australia's pastoral industry and to the unique biodiversity of the rangelands. We ask that anyone seeing these plants in the rangelands contact the nearest DPIRD office and report the location. Department officers will then work with local people to eradicate these plants.
