The species was believed to be extinct for 120 years before it was re-discovered in 1994 in Two Peoples Bay Nature Reserve. These have proved invaluable in allowing them to survive after brush fires that destroy all available food sources apart from those underground (a situation that causes many other mammals to perish) (Hume 1982). They live in a small area, about 1,000 ha (2,471 acres), on the southwest coast near Albany, Western Australia.
