Australia’s Bandicoots Return to the Wild After Genetic Rescue

The eastern barred bandicoot is making a triumphant return to the Australian mainland after being declared extinct in the wild decades ago. Scientists achieved this milestone by cross-breeding the few remaining survivors with a genetically distinct population from Tasmania.

This world-first gene-mixing approach has created a stronger generation of marsupials capable of thriving in various reintroduction sites across the country. The project aims to establish at least 500 animals to ensure the species remains resilient against environmental changes.

Quick Smiles:

• Cross-breeding has ended years of dangerous inbreeding for the species.
• New populations are being released across five distinct locations for safety.
• The project received a significant 2.5 million dollar boost for restoration.

Nature-Based Solutions:

Beyond saving a species, these small marsupials act as ecosystem engineers by burrowing into the earth. This natural behavior significantly improves soil health while protecting the landscape from the impacts of floods and droughts.

“What makes their recovery incredible is the science behind it—a genetic rescue program which is science-backed, scalable, and transformative for conservation,” said Michael Miller.

“The same methodology could help save endangered animals all over the world,” he said.

“We’ve built a fit, feisty bandicoot population with far greater genetic health and a much better chance of survival than their inbred predecessors,” added Dr. Andrew Weeks.

This innovative strategy provides a hopeful blueprint for protecting other endangered species like the eastern quoll and rock-wallaby. By restoring biodiversity, conservationists are building a more sustainable and vibrant future for the Australian wilderness.
