Indigenous Rangers Document Rare Species in Groundbreaking Camera Survey on Truwana
A pioneering camera survey led by Indigenous rangers on Truwana/Cape Barren Island has captured images of rare wildlife, showcasing the importance of traditional land management.
In a significant conservation achievement, Indigenous rangers have conducted the first-ever camera survey on Truwana/Cape Barren Island, located off the coast of Tasmania. This innovative project has resulted in the documentation of two rarely seen species: white-footed dunnarts and blonde echidnas, along with the vulnerable shorebird known as Latham's snipe.
The survey, which took place from November 2024 to May 2025, involved the strategic placement of 30 motion-sensor cameras across seven sites. Upon reviewing the data, the rangers discovered an impressive collection of half a million images. Remarkably, white-footed dunnarts were recorded at six of the seven locations, highlighting a thriving population of this threatened species, which is rarely observed in other parts of its range.
The success of this survey underscores the vital role of the Truwana Rangers in managing local ecosystems. Their efforts in controlling invasive species and restoring habitats through cultural burning practices have contributed to the persistence of small mammals on the island, despite challenges such as feral cats. Truwana was returned to Aboriginal ownership in 2005, empowering local communities to lead conservation initiatives.
The survey also revealed two rare blonde echidnas, which are part of the Tasmanian subspecies known for their thicker fur. This unique coloration may be due to a genetic mutation, making Truwana a potential hotspot for this condition. Additionally, the survey recorded the presence of the Tasmanian subspecies of long-nosed potoroo and the eastern pygmy possum, further emphasizing the island's rich biodiversity.
