Greater bilbies successfully reproduce across Australian red-desert sanctuaries after century absence
Conservation ecologists in central Australia confirmed the birth of more than eighty wild greater bilby joeys inside predator-free desert sanctuaries where the native marsupial had been absent for over a century.
The greater bilby was once widespread across seventy percent of the Australian continent before feral foxes and feral cats drove populations to near extinction. To re-establish the species, the Australian Wildlife Conservancy constructed electrified conservation fencing across thousands of hectares of red-sand dunes, reintroducing eighty founder bilbies into completely protected habitat.
Surveys conducted in October 2026 revealed that ninety percent of adult females are carrying healthy joeys in their pouches, with young bilbies already digging burrows in the spinifex grassland. "Hearing the scurrying of wild bilbies through spinifex dunes at night confirms this ecosystem is finally healing," the sanctuary ecologist said. The bilbies' vigorous digging naturally aerates the soil and traps native seeds and moisture.
Ecologists plan to use the booming sanctuary population to seed future releases into managed unfenced landscapes, accelerating the national recovery of Australia's iconic desert digger.
Native desert species recover crucial soil-tilling marsupials that restore seed germination and plant diversity across arid lands.
