About the guide
Cane needle grass is on the Alert List for Environmental Weeds, a list of 28 non-native plants that threaten biodiversity and cause other environmental damage. Although only in the early stages of establishment, these weeds have the potential to seriously degrade Australia's ecosystems.
Cane needle grass is drought tolerant and forms dense, competitive infestations. It is closely related to serrated tussock, a Weed of National Significance, which costs southeastern Australia's grazing industries more than $40 million annually in control expenditure and lost production. Several species of Nassella have proven difficult to control and have continued to spread since their introduction into Australia, and are now environmental and agricultural weeds.
In addition to loss of production and environmental damage, the sharp seeds of Nassella species can damage sheep skins and carcasses and contaminate fleeces.
