Threats

Risk of local extinction due to low numbers.
Inappropriate fire regimes. There is a risk of population decline with short intervals between fires (less than 10 years) or very long intervals (more than 25 years).
Road construction.
Inappropriate disturbance regimes. This species appears to require disturbance to regenerate, however, if disturbance is too frequent or too intense, there is a risk of population decline. There may also be a population decline if disturbance is not frequent enough to stimulate germination.
Susceptibility to dieback caused by root rot fungus (Phytophthora cinnamomi).
