Special Fencing Project Boosts Charleville Yakka Skink Numbers
A targeted conservation project in Charleville, Queensland, has successfully increased local populations of the threatened yakka skink. University of Southern Queensland PhD candidate Stephen Peck led the initiative, which erected specialized fences around regional skink habitats.
The social reptiles live in family groups and can survive for up to three decades. However, their tendency to remain close to home makes them highly vulnerable to habitat clearing and introduced predators like feral cats and foxes. Three years after installing the protective barriers across four local sites, estimated populations within the enclosures have grown from approximately 10 to 28 individuals.
The fences are specifically designed to exclude introduced mammalian predators while still permitting native predators, such as snakes and birds, to enter. Researchers noted that some skinks raised safely within the enclosures have grown to a mature size of about 400 millimeters and established new colonies outside the fenced boundaries.
Experts highlight that while local barrier projects offer a viable blueprint for conservation, broader challenges remain. Monash University ecologist David Chapple noted that Australia currently lists 127 threatened reptile species, emphasizing that addressing knowledge gaps and implementing well-funded recovery plans will be essential for wider species protection.
