Australia's Wildlife Fightback: Foxes Defeated

European red foxes, introduced to Australia in the mid-nineteenth century for hunting, became a devastating invasive predator. Native Australian mammals, having evolved without such efficient killers, lacked defenses, leading to significant population declines and extinctions. This crisis prompted Western Australia's wildlife managers to initiate large-scale predator control programs.

The Western Shield program, established in 1996, employs landscape-scale 1080 poison baiting to suppress fox populations across millions of hectares. This science-based approach has proven remarkably effective, with native species like the woylie and numbat showing substantial recovery in areas where fox numbers have been reduced. The program's success is partly due to many native animals' natural tolerance to 1080, a toxin found in local plants.

As of 2026, Western Shield is one of Australia's major conservation successes. It has expanded to cover approximately 3.8 million hectares, with ongoing monitoring and adaptive strategies. The program has facilitated over 140 translocations of 27 native species, aiding the restoration of wildlife in areas previously devastated by invasive predators, demonstrating that science-backed conservation can achieve recovery even after severe declines.
