    Climate change modelling for the south west predicts a decline in rainfall; and some seasonal shift to summer rainfall events; which is likely to increase the potential impact of drought on the species.

    They also increase the fire hazard.

    Past; present and future Altered fire regimes Whole population Severe Although the species may germinate from soil stored seed following fire; it may not have enough time to set seed and recover if the interval between fires is too short.

    Current; future Drought Whole population Severe This is a threat to the species if it occurs over a number of years.
