FAME’s partnership with WWF-Australia and the Nyikina Mangala Rangers to protect the endangered wiliji (West Kimberley rock-wallaby) has now been successfully completed, delivering critical conservation outcomes on Country.
Following devastating wildfires in 2023, which burned more than 13,300 hectares of habitat and caused a 32% decline in wiliji numbers in some areas, this project enabled an immediate and coordinated response. Emergency supplementary feeding supported survival in the short term, while longer-term threat management strategies were rapidly established.
Over the course of the project, Rangers implemented an integrated program combining feral predator control, fire management, and cutting-edge population monitoring. Five Felixer grooming traps were deployed and maintained, successfully targeting feral cats in key wiliji habitats, while camera surveys across the Grant Range estimated a population of approximately 259 individuals, providing a vital benchmark for future conservation efforts.
Equally important was the strengthening of Indigenous-led conservation. Nyikina Mangala Rangers led fire planning and delivered mosaic burning to protect critical habitat, while also building skills in wildlife monitoring, data analysis, and land management. Community engagement and knowledge sharing further reinforced the cultural significance of wiliji and the importance of caring for Country.
This project represents the first coordinated, strategic threat management effort for wiliji on Nyikina Mangala Country, laying a strong foundation for long-term recovery. With FAME’s support, the wiliji is now positioned as a flagship biocultural indicator, guiding future conservation and climate adaptation efforts.
Looking ahead, the next phase will focus on Indigenous-led governance, climate resilience, and the establishment of an Indigenous Protected Area, ensuring that both wiliji and Country are protected for generations to come.
