 The population occurs in two geographically remote regions in the east and west of the continent.The habitat in the east is heathlands and heath-like scrub in treeless areas, the preferred vegetation type in southwest Australia is taller scrubland associated with mallee trees and climax heath assemblages in undisturbed areas.The population structure is responsive to fire, requiring a complex of climax vegetation—that has not been exposed to burning—and recently burnt areas to maintain an equilibrium in their relative abundance.
