The species may undergo extreme fluctuations in numbers immediately after fire (DEC; 2009).
Threats Past N A Present Inappropriate fire regimes may affect the long term viability of the species.
Changes to fire frequency and intensity could mean that the species either does not have time to adequately grow and set seed before the next fire; or if the interval between fires is too long; then seed lying dormant in the soil may not be stimulated to germinate (DEC; 2009).
