Newhaven

The Sanctuary

Covering almost 262,000 hectares, and located near the intersection of three central Australian bioregions, Newhaven Wildlife Sanctuary is one of Australia’s largest non-government protected areas. The scenery on the property is spectacular, with extensive sand dunes and salt lakes overlooked by dramatic quartzite mountains. Protecting areas of mulga woodlands, spinifex sandplains, bloodwood and desert oak, Newhaven is a hotspot for the wildlife of central Australia. Threatened species include the Black-footed Rock-wallaby, the Brush-tailed Mulgara and an important population of the Great Desert Skink.

The rugged ranges, salt lakes and sand plains of Newhaven are the traditional lands of the Ngalia-Warlpiri/Luritja people. A historic native title consent determination in 2010 recognised the Ngalia-Warlpiri/Luritja people as the traditional owners of Newhaven. Members of the local Indigenous community are actively involved in Newhaven’s management, participating in AWC’s delivery of major land management and science programs such as fire management, feral animal control and biological surveys.

Newhaven is renowned as a key arid zone bird watching destination. Supporting 174 species of birds, the property was originally purchased by Birdlife Australia before being transferred to AWC in 2006.

Newhaven is the site of the planet’s largest feral cat eradication project, involving the establishment of a massive feral cat-free area that will ultimately protect  up to 100,000 hectares from feral predators. The project is of global biodiversity significance – the first stage (9,400 hectares) creates a refuge for wild populations of at least 10 nationally threatened mammal species that are set to be restored here.

The property encompasses an incredible range of landforms and habitat types. The southern section is characterised by a vast expanse of parallel sand dunes, and further north lies an extensive system of salt lakes along an ancient drainage line which runs from east to west across the property, culminating at Yunkanjini (Lake Bennet). The salt lakes rarely contain water, filling only after flooding rains. In the north eastern corner of Newhaven, bluff-edged ranges rise to 800 metres above the plains, and Black-footed Rock Wallabies survive among the rugged boulders and gorges.

Each of these landforms supports its own diverse range of plant communities that vary in response to topography, soil, and fire history. Newhaven sits near the junction of three bioregions, giving it a rich diversity of habitats. Broad vegetation mapping has identified at least 23 different ecosystems, all of which are either threatened, or poorly reserved within the government national park system. Over 600 plant species have been confirmed on the property, including 5 that are classified as threatened in the NT.

Spinifex sandplains dominate the landscape, broken up by shimmering salt lakes fringed with unique communities of salt-adapted plants. Elsewhere, the property features large areas of bloodwood, dunefields dotted with majestic desert oaks, and calcrete grasslands with majestic Ghost gums. In the north, run-off from the dramatic quartzite ranges supports small but significant patches of Mulga woodland.

Newhaven lies in the arid zone of central Australia. It receives most of its rainfall in the summer months, but there are high levels of spatial and temporal variability in rainfall across the region. Decadal cycles of below average rainfall (El Niño) are broken by extremely high rainfall events, leading to the evolution of a suite of flora and fauna specially adapted to these boom and bust cycles.

Wildlife at Newhaven

The range and quality of habitats across Newhaven protect a stunning diversity of arid zone birdlife. In the rugged quartzite ranges are Grey Shrike Thrush, Painted Finches, Dusky Grasswren and Spinifex Birds. Princess Parrots feed within the dunefields during their nomadic desert flights to the east. Other arid zone specialist species include the Banded Whiteface, Grey Falcon, Rufus-crowned Emu-wren, Slaty-backed Thornbill, Grey Honeyeater and the Redthroat.

The mammal fauna of Newhaven is also exceptional. The MacDonnell Ranges race of the Black-footed Rock-wallaby (Petrogale lateralis ssp), which is now absent from Uluru and Kata Tjuta and declining elsewhere, is still present on the Quartzite ranges of Newhaven. Other threatened mammals include a significant population of the Brush-tailed Mulgara, the Southern Marsupial Mole and a range of native rodents and small marsupials such as the carnivorous Fat-tailed False Antechinus. Newhaven lies within the former range of at least ten other endangered mammals, and AWC plans to reintroduce many of them over the coming years.

There are over 80 species of reptiles at the sanctuary, including one of Australia’s smallest goannas (the Short-tailed Pygmy Goanna) and our largest (Perentie). Notably, Newhaven protects the largest known population of the nationally threatened Great Desert Skink.

Populations of small mammals boom during the wetter years, when a network of ephemeral lakes become breeding sites for migratory birds. Burrowing frogs that have been lying dormant under the sand waiting for rain, also emerge at this time.

Wildlife Reintroductions at Newhaven

AWC’s Mala reintroduction program at Newhaven began with an urgent intervention in 2017, triggered by a substantial decline in the Watarrka National Park insurance population. Working with the Northern Territory Government, AWC undertook an emergency translocation of 27 Mala to Newhaven. Since then, AWC has carried out two further reintroductions, transferring 34 Mala from Scotia in 2018 and 9 individuals from Alice Springs Desert Park in 2019. In 2020, the last of the Mala from AWC’s Scotia Wildlife Sanctuary were restored to their historical range in Australia’s red centre – marking the final round of AWC’s planned Mala releases into Newhaven’s Stage 1 fenced area.

That same year 29 Red-tailed Phascogales were reintroduced in June, followed by another 61 sub-adults in November.

In August of 2021, AWC celebrated 30 years of effective conservation work with the successful reintroduction of 44 Woylies (Brush-tailed Bettongs) to the sanctuary from our Mt Gibson Wildlife Sanctuary in the WA Wheatbelt region.

In May of 2022, thanks to a national collaboration with Taronga Conservation Society Australia, 32 Greater Bilby were released into the feral-predator free area, followed by 65 Burrowing Bettong (known by the Warlpiri name ‘Purdaya’) in June.

AWC is now planning reintroductions of other important marsupials; including Golden Bandicoots, and the critically endangered Antina (Central Rock-rat). In the coming years, AWC plans to expand the already vast 9,450-hectare feral predator-free safe-haven to protect a colossal 100,000 hectares. This project is a globally important conservation initiative that will see species saved and biodiversity restored in central Australia.

AWC Field Programs at Newhaven

The effective conservation land management program at Newhaven serves as a model for central Australia. We support an indigenous ranger group, who work closely with staff on fire management, predator eradication and general sanctuary management, and there is a high level of scientific activity on the property. The focuses of the field programs include:

• Fire management – involving prescribed burning in the cooler winter months, and fire suppression in the summer months. The fire program aims to reduce the effect of severe summer wildfires that have the potential to burn intensely across large areas, and are a major threat to biodiversity. Prescribed burns create a patchwork of post-fire regeneration, limiting the spread of wildfires and protecting patches of crucial old-growth habitat.
• Weed control – Newhaven has relatively few weeds, however, two of central Australia’s most significant weeds occur on the property: Buffel Grass (Cenchrus ciliaris) and Couch Grass (Cynodon dactylon). Buffel grass is drought resistant, and fills in the spaces between Spinifex clumps, encouraging the spread of wildfire. Couch grass occurs around bores, and has the potential to spread to the fringes of claypans and salt lakes, displacing crucial native vegetation. Watch a video about our weed program at Newhaven.
• Feral herbivore control – Feral camels are the only large feral herbivore on Newhaven that requires dedicated management and control. The population of feral horses and donkeys is effectively zero. Grazing by camels threatens a number of native plants, and large herds of camels compete with native wildlife for valuable water resources. They are controlled through aerial culling. Rabbits are also a threat to the health of the ecosystems on Newhaven, and are controlled through forced outbreaks of Rabbit Calicivirus, and strategic baiting programs.
• Feral cat and fox control – Feral cats and foxes occur across central Australia and are a primary cause of the disappearance of many small-medium sized mammals. Newhaven is the site of a globally significant biodiversity project, establishing the world’s largest feral cat and fox-free area, with a fence that will protect up to 100,000 hectares. The area will protect an array of different habitats, and pave the way for the reintroduction of central Australia’s lost and threatened mammals, including the Mala (currently extinct in the wild), the Central Rock Rat and the Golden Bandicoot. Cats and foxes are also removed from threatened species sites such as Great Desert Skink populations, and AWC is conducting research across its sanctuaries to come up with a landscape-scale solution to feral cats.
• Scientific surveys and research – including large-scale annual biological surveys to measure ecological health, dedicated research on key species such as the Great Desert Skink and long-term monitoring of bird populations. The annual survey effort involves over 8,000 live trap nights, bird surveys, vegetation surveys small mammal and reptile surveys, track surveys for feral animals, Black-footed Rock-wallaby surveys, as well as other targeted threatened species monitoring. This provides AWC with rigorous scientific data, allowing us to measure our performance against a range of ecological health indicators. A number of research projects by postgraduates and collaborators are also being carried out at Newhaven.
• Wildlife Translocations – The Mala is the first of 10 threatened mammal species to be reintroduced to Newhaven. AWC’s Mala reintroduction program at Newhaven began in 2017, when AWC undertook an emergency translocation of 27 Mala in partnership with the Northern Territory Government. Since then, AWC has carried out two further reintroductions of the species, transferring 34 Mala from Scotia in 2018 and 9 individuals from Alice Springs Desert Park in 2019. The Red-tailed Phascogale was the second species to be restored; with 29 released in June 2020, followed by 61 in November 2020. Over the coming years reintroductions of other important marsupials are planned including Golden Bandicoots, and the critically endangered Antina (Central Rock-rat).
