    The main threats to this species are clearing for development and grazing; there is also the potential for road and firebreak maintenance; weed invasion; inappropriate fire regimes and recreational impacts to become a threat (Stack English; 2004).

    Dormancy periods may be artificially lengthened by the heat produced by fire (Stack English; 2004).

    There is some decline in area of occupancy due to clearing and inappropriate fire and as land clearing and development continues to threaten subpopulations it is likely to continue to reduce the area of occupancy in the immediate future (CALM; 2006).
