About the guide

Lobed 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.

Even in its native Argentina, where the relatively unpalatable serrated tussock and Chilean needle grass are used as fodder, lobed needle grass is regarded as a serious weed due to its invasiveness and competitiveness. It is drought tolerant and forms dense infestations. While cattle may be able to tolerate lobed needle grass, it is a major problem for sheep because the sharp seeds can damage skins and carcasses and contaminate fleeces.

Lobed needle grass is closely related to serrated tussock (Nassella trichotoma), a Weed of National Significance which costs southeastern Australia's grazing industries more than $40 million a year in control expenditure and lost production.
