While the species appears to regenerate from seed after fire; frequent fire is likely to impact on the ability of the species to regenerate or to mature and replenish the soil seed bank (Stack English; 2002).
As discussed under criterion 1; with the ongoing threats of road side maintenance; weed invasion and inappropriate fire regimes to all known populations; it is likely the quality of the species habitat and species numbers will undergo a decline.
Due to the ongoing threats of road side maintenance; weed competition and inappropriate fire regimes impacting on the species; and its severely fragmented distribution; it is likely that the area and quality of its habitat will continue to decline; resulting in a further reduction in numbers of mature individuals.
With the ongoing threats of road side maintenance; weed competition and inappropriate fire regimes; the numbers are likely to decline further.
Available evidence indicates that the species has undergone a significant decline in population numbers during the past three years; and is likely to undergo a further decline as all six populations are under threat from road side maintenance; weed competition and inappropriate fire regimes.
