Bilby Population Surges in Australian Sanctuaries: A Fourfold Increase Since 2021

The Australian Wildlife Conservancys recent census reveals a remarkable surge in bilby numbers across six sanctuaries, with a fourfold increase since 2021, reaching a total of 5,330. These cute, Easter bilbies, also known as greater bilbies, have made a strong comeback in spots across the Northern Territory, Western Australia, South Australia, and New South Wales.

Key factors contributing to this boom include reintroductions, such as the successful release of 66 bilbies at Newhaven Sanctuary in the Tanami Desert, which grew to 530. Additionally, good rains and smart land management have played a significant role in the surge.

Historically, bilbies roamed three-quarters of Australia until cats, foxes, and colonization wiped out most of the population. Now, sanctuary experts celebrate how these diggers enrich the soil, sprout seeds, and boost other species like bettongs that upgrade their burrows into massive warrens.

Fences, fire control, and weed sprays have helped protect bilbies from predators and create a thriving environment. Wildlife ecologist Tim Henderson notes that plentiful food has allowed bilbies to thrive without threats, creating richer landscapes for everyone.

Despite potential droughts that may trim numbers at Newhaven, the population is primed to rebound quickly when rains return, demonstrating the growing momentum for Australias wild heart conservation efforts.
