Bandicoots are small, native Australian marsupials that use their front feet to dig for food. There were eight bandicoot species in Western Australia when Europeans settled in the country, but today, only three have survived. The southern brown bandicoot, a subspecies found in Western Australia, is known as the quenda in the local Noongar language. The Long-nosed Bandicoot and Northern Brown Bandicoot are not endangered, but the loss of bushland has caused local extinctions. Bandicoots face threats from habitat loss, predation by invasive species, and frequent burning, which destroys their shelter. Conservation efforts are underway to protect bandicoots and their habitats, including buying properties to create permanent refuges and implementing fire management.

What You'll Learn
Bandicoots are native to Australia and New Guinea
Bandicoots are small marsupials native to Australia and New Guinea. They use their front feet to dig for food, leaving behind small conical holes known as "snout pokes". The name "bandicoot" is derived from the term "pandi-kokku" in Telugu, an Indian language, which means "pig-rat".
There are currently seven species of bandicoots surviving in Australia, with two-thirds of the nine species present at the time of European settlement now considered extinct or threatened with extinction. The main threats to bandicoots are habitat loss from urbanisation, land-clearing, predation from introduced species such as foxes, cats, and dogs, and collisions with vehicles.
Bandicoots are solitary, terrestrial, and nocturnal animals. They have strong hind legs adapted for jumping and low body temperatures, which aid their survival in hot and dry climates. Their digging behaviour is considered critical for maintaining the ecosystems in which they live, as it helps trap moisture and allows for seed germination.
The Long-nosed Bandicoot (Perameles nasuta) is found along the east coast of Australia, from north Queensland to Victoria and Tasmania. The Northern Brown Bandicoot (Isoodon macrourus) is found along the coastline of northern and eastern Australia, extending into southern Papua New Guinea. Both species can inhabit a variety of habitats, including heaths, woodlands, and rainforests, and prefer areas with dense vegetation for shelter and open spaces for foraging at night.
Conservation efforts are underway to protect bandicoot habitats and ensure their survival for future generations.

Bandicoots are small, slender-snouted marsupials
There are currently seven species of bandicoots surviving in Australia, with three others having gone extinct within the boundaries of the present-day state of Western Australia. The southern brown bandicoot, a short-nosed variety, is one of the species found in Western Australia. It is mostly restricted to the southern coastal regions of mainland Australia and the island state of Tasmania, with a subspecies found in southwestern Western Australia.
The northern brown bandicoot is another species of bandicoot, and its range follows the coastline of northern and eastern Australia, extending as far south as New South Wales. It is also found in southern Papua New Guinea and can live in a variety of habitats, including heaths, woodlands, and rainforests. The Long-nosed Bandicoot is found along the east coast of Australia, from northern Queensland to Victoria and Tasmania.
Bandicoots are solitary, terrestrial, and nocturnal marsupials, spending much of the night searching for food. They primarily detect their prey by scent, sniffing the ground before digging into it with their claws. They pursue any prey that escapes, holding it down with their forepaws as they consume it. Bandicoots play a critical role in maintaining the ecosystems in which they live, as their constant digging helps trap moisture and allows for seed germination.
Unfortunately, bandicoots face several threats, including habitat loss from urbanisation and land-clearing, predation from introduced species such as foxes, cats, and dogs, and collisions with vehicles. Intense wildfires or too frequent burning also negatively impact their survival, as it destroys their shelter and makes them more susceptible to predators. Conservation efforts are underway to protect bandicoots and their habitats, ensuring their survival for future generations.

Bandicoots are threatened by habitat loss, invasive species, and predators
Bandicoots, small marsupials native to Australia and New Guinea, are threatened by habitat loss, invasive species, and predators. There are seven species of bandicoots surviving in Australia, including the Long-nosed Bandicoot and the Northern Brown Bandicoot. Bandicoots play a critical role in maintaining ecosystems, dispersing fungi spores, and promoting soil health through their digging and foraging behaviour.
Habitat loss due to urbanisation, land-clearing, and agriculture is a significant threat to bandicoots. Since European settlement, the bandicoot's range has greatly reduced, and the loss of bushland around suburban areas has led to local extinctions. Bandicoots prefer habitats with dense vegetation for shelter and open areas for foraging, but these habitats are increasingly threatened by human activities.
Invasive species, such as rabbits, deer, and other introduced herbivores, also pose a significant threat to bandicoots. These invasive species compete with bandicoots for food and habitat, and they remove undergrowth used by bandicoots for shelter and refuge, making them more vulnerable to predators. Rabbits, in particular, have been targeted by conservation efforts, with initiatives to remove and control their populations in bandicoot habitats.
Predation by introduced species, including foxes, feral cats, and dogs, has had a severe impact on bandicoot populations. Native predators, such as snakes, owls, quolls, and dingoes, also pose a threat. The Eastern Barred Bandicoot, for example, experienced a decline primarily due to fox predation and habitat loss. Captive breeding initiatives and the establishment of predator-exclusion fences have been implemented to protect vulnerable bandicoot populations.
Bandicoots are also susceptible to vehicle collisions when they wander into roads. In addition, frequent or intense wildfires can destroy their shelter, further exposing them to predators. Conservation efforts, such as habitat restoration, the creation of safe habitats, and support for dedicated conservation programs, are vital to safeguarding bandicoot populations and ensuring their survival for future generations.

Conservation efforts are helping to protect bandicoots
Bandicoots are small marsupials native to Australia and New Guinea. They use their front feet to dig for food, leaving behind a series of small conical holes known as "snout pokes". The name "bandicoot" comes from the term "pandi-kokku", which means "pig-rat" in the Indian language Telugu. While there were nine species of bandicoot in Australia at the time of European settlement, today only seven species survive, and two of these are considered extinct or threatened with extinction.
The Wild Deserts conservation program is also working to protect bandicoots. They are using descendants of a few thousand bandicoots that survived on two predator-free islands in Shark Bay, off Australia's western coast, to seed a mainland bandicoot revival. They have imported 20 bandicoots to a preserve on the edge of the Strzelecki Desert, in the remote interior of New South Wales. This sanctuary is challenging due to its unpredictable rainfall patterns, but the imported bandicoots occupy two fenced "exclosures" that have been cleared of invasive rabbits and feral cats.
In Victoria, Parks Victoria and several partners are working on a ten-year project to protect the Southern Brown Bandicoot, which is considered endangered in the state. The Southern Brown Bandicoot Protection Program aims to control fox populations and reduce fox predation, with up to 60 foxes culled across two reserves each year. The Mornington Peninsula and Western Port Biosphere Reserve Foundation Ltd received funding through the Threatened Species Network Community Grants in 2007-08 to expand extant populations of Southern Brown Bandicoots in the Melbourne-Westernport region. They established management strategies to ensure continuity of effort, extended habitats with understorey plantings, and implemented community awareness programs.
In Western Australia, the Southern Brown Bandicoot has been reintroduced to some lower rainfall areas where there is protection against cat and fox predation, such as at Wadderin Sanctuary in the eastern wheat belt of Western Australia.

Southern brown bandicoots are found in Western Australia
Bandicoots are small marsupials native to Australia and New Guinea. They use their front feet to dig for food and play a critical role in maintaining the ecosystems in which they live. Unfortunately, several bandicoot species have gone extinct, and many surviving populations are locally extinct. The primary threats to bandicoots include habitat loss from urbanisation, land-clearing, and frequent burning, as well as predation from invasive species such as foxes, cats, and dogs.
Despite these challenges, southern brown bandicoots (Isoodon obesulus) can be found in Western Australia. This subspecies, known as the quenda in South Western Australia, was elevated to a species in 2018. Southern brown bandicoots have a stocky body with a short snout and short, rounded ears, and they exhibit sexual dimorphism, with females being smaller than males.
In Western Australia, southern brown bandicoots are found in isolated and increasingly restricted populations in south-western regions of the state. They inhabit open forests, scrub, and heathland, particularly where there is extensive ground cover provided by shrubs or mat-rushes. The Wadderin Sanctuary in the eastern wheat belt of Western Australia, located about 300 km east of Perth, is one such site where southern brown bandicoots have been reintroduced to protect them from cat and fox predation.
Southern brown bandicoots are nocturnal and spend much of the night searching for food, which they detect primarily by scent. They feed on insects, spiders, worms, plant roots, ferns, and fungi. During the day, they sleep in well-concealed nests made from grasses and other plant material. Reproduction is closely linked to local rainfall patterns, and they can breed year-round, producing up to four litters per year.
While southern brown bandicoots are classified as Least Concern by the IUCN, their populations have declined significantly and become fragmented since European expansion on the Australian mainland. They are considered endangered in New South Wales and rare in South Australia, where they are primarily found in the extreme southeast and on Kangaroo Island. Conservation efforts are crucial to ensuring the survival of southern brown bandicoots in Western Australia and across their range.
