    Threats The main threats to the species are weed invasion; grazing and trampling; road; track and firebreak maintenance; changed fire regimes; motorbikes and off road vehicles; illegal picking and whole plant collection; poor recruitment and future mining operations (DEC 2012).

    They also increase the likelihood of fire due to the easy ignition of high fuel loads; which are produced annually by many grass weed species (DEC 2012).
