Arid Recovery is divided into six large enclosures, each of which can be manipulated to suit research at a landscape scale. This allows us to keep effective control areas, and directly study the before-and-after impacts of management decisions and reintroductions.
Main Exclosure 14 km2
Both the internal and external fences are predator-proof (tall with a floppy top), meaning we can exclude feral cats outside the Reserve as well as limit movement of Western Quolls. We aim to keep this pen free from both feral and native mammalian predators, so that we can measure the effects they have on the ecosystem. Maintaining the area is also a critical insurance area in case the reintroduction of Western Quolls into the Reserve has unintended consequences on some native animals.
Core Conservation Area
First Expansion 8 km2
This is the first pen every visitor sees and is where our research station and education centre are located. It is also free of all feral animals and supports populations of all four reintroduced species.
Second Expansion 8 km2
When the reserve was first built, we created a paddock free from both feral animals and native threatened mammals. This allowed the paddock to operate as a control treatment for scientific research, allowing us to disentangle the impacts of reintroduced native animals from the impacts of removing ferals. The paddock has played a critical role in many scientific publications, including research uncovering the positive impacts that bilby digs have on soil condition.
The pen is no longer functioning as a control, and bilbies and bettongs have now returned to the paddock. By increasing the area for these native species, it will allow better gene flow throughout the reserve and increase the area available for animals like the Western Quoll.”
Northern Expansion 30 km2
This is our largest feral-free paddock. It includes a diverse range of habitats, from long and complex sand dunes, gibber flats and cypress pine patches, to a huge canegrass swamp. Due to its size, this was the last area from which rabbits were removed – taking a full two years.
Red Lake Expansion 26 km2
After this fence had been built and the feral cats and foxes removed, we realised that the future of conservation research in Australia will be uncovering how to enable coexistence between cats and threatened native wildlife. We made the difficult decision to return feral cats into this paddock in a carefully controlled experiment. Our goal is to train bilbies and bettongs to develop appropriate behaviours for surviving alongside feral predators, so that one day they might be able to survive outside the fence entirely.

Dingo Paddaock 37 km2
This paddock was built for Australia’s most detailed study on the interaction between cats, foxes and dingoes. It is a very large area and has a permanent water source, allowing at least two dingoes to live naturally within it. For the experiment, all cats and foxes were removed, and new cats and foxes with GPS collars added. After these animals had time to settle into the paddock, two GPS collared dingoes were also added.

The Dingo Paddock is the ideal place to conduct landscape-scale experiments using feral animals in a manageable setting. The paddock is still the site for cutting-edge research. We were recently able to simulate the original rabbit Calicivirus to uncover the impacts it had on cats that prey on rabbits and new innovations to help threatened species survive beyond the fence.
