Over the last six months – and since the previous project update – there’s been significant progress toward the goal of establishing an additional subpopulation of the Nangur Spiny Skink (Nangura spinosa) and increasing the critically small population at Nangur National Park (NP).
Population surveys at Oakview NP
Conducted in October 2024, these surveys systematically examined seven 1-hectare plots and 2.6km of transects for active skink burrows. Preliminary results show the Oakview NP subpopulation remains stable in high-density areas, though marginal areas face slow declines due to threats and habitat conditions. This data will guide future in-situ land management, translocations and genetic dispersal strategies.
Release site monitoring at Wrattens NP
Surveys in November 2024 revealed a survival rate of at least 74% among released mature skinks. Juvenile survivorship is estimated at 59%, though ongoing monitoring suggests many juveniles are thriving within the hoop pine litter. With 15 additional skinks released in December 2024, the release subpopulation now comprises at least 46 individuals (23 mature and 23 immature).
Captive breeding success
Six females in the Nangur NP genotype breeding program are likely pregnant, potentially making January 2025 one of the most successful breeding seasons to date. A trial cross between a Nangur NP female and an Oakview NP male is underway, with outcomes critical to future genetic diversity strategies. Genetic sequencing results, expected shortly, will guide pairings for the next breeding season.
These milestones highlight the rapid establishment of a new subpopulation at Wrattens NP and the increasing success of our captive breeding efforts. By focusing on genetic diversity, population monitoring, and habitat restoration, we are paving the way for a secure future for the Nangur Spiny Skink.
