being 2,919km2. Much of its habitat has been cleared for agriculture and road development, so the species is only known to persist in fragmented populations along roadside verges. Major threats to this species include land clearing for urban development, roadside verge clearance and competition with weeds. A population decline of at least 50% over the next 3 of the species' generational lengths (75 years) is inferred from additional habitat clearing for road development and maintenance. It is unknown if this species is susceptible to dieback, a disease caused by the plant pathogen, '' Phythophthora''. It is also listed as " Priority Three" by the Government of Western Australia
