Notes

Birdwood grass (Cenchrus setigerus) often dominates grasslands and the understorey layer of savanna woodlands in northern Australia. During a recent survey, this introduced grass was listed as a priority environmental weed in one Natural Resource Management region.

It is also common in coastal habitats and is ranked among the top ten environmental weeds in the coastal districts of the Kimberley and Pilbara regions of northern Western Australia. Birdwood grass (Cenchrus setigerus) is also regarded as an environmental weed in the desert uplands bioregion in Queensland and grows on red sandy soils in bimble box communities in inland New South Wales.
