About the guide

Serrated tussock is a Weed of National Significance. It is regarded as one of the worst weeds in Australia because of its invasiveness, potential for spread, and economic and environmental impacts.

It mainly causes problems in grazing lands with poor soil fertility and low rainfall where the benefits of control are marginal. Serrated tussock has no grazing value because of its high fibre and low protein content. Infestations result in a significant loss in livestock production, and dense infestations may completely dominate pasture, making large areas incapable of supporting livestock. Trials on heavily infested areas of New South Wales have shown a loss of production of up to 95%. In native grasslands serrated tussock reduces biodiversity, and in urban areas it creates a fire hazard.

Serrated tussock has become a major agricultural weed because of the high costs associated with its spread. In New South Wales alone it has been estimated that the weed has cost more than $40 million in lost production.

This management guide was prepared in 2003. The state and territory contacts in this document may be out of date.
