Project Update: A Remarkable Step Forward for the Nangur Spiny Skink

Breeding Success and Genetic Rescue in Action
Earlier this year, nine Nangur females gave birth to a total of 34 offspring, the largest breeding success since the program began. Among them were four juveniles from a groundbreaking cross between the Nangur and Oakview populations — the first time this genetic rescue strategy has been trialled. These young skinks are thriving in captivity, marking an important step toward strengthening the genetic diversity of the Nangur population and ensuring its long-term survival.

Reintroduction Plans Underway

In parallel with this breeding success, the team has begun preparing for the species’ return to the wild. In July, a secure 600m² release site was established at Nangur National Park (NP), complete with protective fencing and artificial burrows. This site will host the first reintroduced skinks within the next 12 months — a major milestone in the recovery of the species.

Monitoring & Conservation
While comprehensive surveys in Nangur NP this year unfortunately confirmed there are no remaining wild individuals, the newly established captive population gives us real hope for restoring the species to its former range. At the Wrattens release site, monitoring shows that translocated skinks are surviving well, with strong breeding behaviour already observed — proof that reintroductions can succeed. Meanwhile, ongoing efforts to control weeds and predators are making habitats safer across all three national parks.

This project is now delivering results that were almost unimaginable just two years ago.

The next phase of work will focus on boosting genetic diversity further. Later this year, wild-to-wild translocations from Oakview to Wrattens NP will begin, helping to establish a population that represents almost all of Oakview’s genetic diversity. Additional surveys at Nangur NP in 2026 will also help identify future release sites.
