Reintroduction in Sturt National Park
After two years of captive breeding behind pest-free exclosures in north-west New South Wales, a handful of burrowing bettongs were released into a 100-square-kilometre “wild training zone” inside Sturt National Park, near the Cameron Corner tri-state point. Each animal was fitted with a radio collar so ecologists can track movements, habitat use and survival in real time.
Historical Decline and Predator Threats
The burrowing bettong, a football-sized marsupial related to kangaroos, once occupied much of Australia’s arid interior. Within a century of European settlement it disappeared from most of the mainland, primarily due to predation by feral cats and foxes. Australia now records the world’s highest mammal extinction rate, and the Department of Climate Change, Energy, the Environment and Water estimates feral cats kill more than 1.5 billion native animals annually.
The Wild Deserts Collaboration
The project is a decade-long partnership led by the University of New South Wales (UNSW) Centre for Ecosystem Science, working with Ecological Horizons, the NSW National Parks and Wildlife Service, and Taronga Conservation Society Australia. Principal ecologist Dr Rebecca West, project leader Prof Richard Kingsford, and conservation field officer David Damschke coordinate the effort. Bettongs join previously re-introduced species such as bilbies, golden bandicoots, western quolls and crest-tailed mulgaras.
Training Zone and Release Strategy
Two fenced “safe havens” protect the breeding population from predators; beyond them, the training zone maintains a low density of feral cats and foxes through systematic shooting and trapping. Over the past 18 months, 400 bilbies have been released into the same area. The team plans to release roughly 20 bettongs, each capable of turning over about three tonnes of soil per year, thereby enhancing soil health and seed dispersal. Radio collars enable intensive monitoring, and genetic swabs will be taken from any deceased individuals to determine cause of death.
Ecological Role and Expected Impact
Bettongs are considered “ecosystem engineers.” Their digging activity aerates soil, recycles nutrients and creates burrows that provide refuge for other fauna. The ultimate goal is to teach bettongs predator-avoidance behaviours that did not evolve alongside introduced cats, enabling them to breed and sustain populations in a landscape where low-level predation persists.
Official Statements & Responses
Dr West highlighted the species’ contribution to soil turnover and refuge creation, noting that bettongs must now “learn to listen when they’re feeding… to make sure they have really good safety.” Prof Kingsford stressed daily tracking and post-mortem analysis to identify predator-related mortality, describing this as essential for adaptive management. Damschke emphasized that while animals thrive in predator-free fences, “getting them beyond the fence… back into the landscape… is the key part.”
On-the-Ground Reports
Field observations confirm that bilbies are dispersing widely and showing strong breeding signals within the training zone. Damschke reported that bettongs are already exhibiting heightened vigilance, a behavior expected to improve survival as they acclimate to low-density predator environments.
Conflicting Reports & Gaps
Sources do not disclose the exact number of bettongs released, nor provide early survival statistics. No criticism or opposition to the project is mentioned in the available reports.
Verbatim Quotes
- “They are very important in terms of turning over the soil and nutrients and seed cycling, but also providing refuges for other animals,” — Dr Rebecca West, Principal Ecologist, Wild Deserts
- “We know that animals can live in a fence where there's no predators and nothing to worry them,” — David Damschke, Conservation Field Officer
- “But, getting them beyond the fence and back into the landscape where they can continue on their natural function and the ecological role, that would be the key part.” — David Damschke
- “They're going to be learning to listen when they're feeding, to look around them to make sure that they've got really good safety and that they're not moving too far from their warrens,” — Dr Rebecca West
- “If we find one that's been killed, we've got an opportunity to work out what happened to it.” — Prof Richard Kingsford, Project Leader
What’s Next
The team will continue radio-tracking bettongs for several months, assess breeding success, and refine predator-management protocols. Successful adaptation could pave the way for larger releases and inform similar predator-training programs for other threatened Australian marsupials.
