Charnley River-Artesian Range has a vital role to play in protecting and restoring the endangered wildlife of northern Australia. The Yampi Sound Training Area is an area of outstanding conservation value, with the highlands having been virtually untouched for The Bilby is an iconic Australian marsupial, instantly recognisable by its long pointed snout, long ears, soft grey fur and The Numbat is unique among Australian mammals.

Home Wildlife Golden Bandicoot. Quick Facts. What is AWC doing? Threats to Species The demise of the Golden Bandicoot across much of Australia has been largely attributed to predation by feral predators mainly foxes and cats.
Ecology When foraging at night the Golden Bandicoot moves between clumps of grasses and makes small conical diggings for its diet of insects, small vertebrates, roots and tubers. On Marchinbar Island, the Golden Bandicoot is found in heath and open woodland vegetation types but not in sand dunes, coastal thickets or rainforest.
Kimberley populations occur in a high rainfall — mm area. The Golden Bandicoot appears to be a solitary, discrete and restricted species, although home ranges have some overlap. On Marchinbar Island, home ranges vary from 4. Home ranges tended to be larger in the dry season, but only slightly and tend to centre on nest sites. Based on scat analysis of Golden Bandicoot populations on Marchinbar Island, the diet of this species consists of arthropods beetles, termites, ants, larvae, spiders and centipedes.
Western Australian mainland populations have been recorded eating insects, arachnids and plant material. Golden Bandicoot Barrow Island populations have been recorded eating eggs and reptiles.
Populations on Marchinbar Island are sexually dimorphic and larger than those on Barrow Island, but smaller than those in the Kimberley. Marchinbar Island populations appear to breed all year round, whereas Barrow Island populations have a strong summer peak. Breeding on Marchinbar Island appears to be continuous as pouch young and juveniles are found in all seasons.
Change in fire regimes has also negatively affected populations of bandicoots. Golden bandicoots have no cover after a fire and are easily preyed upon by non-native predators. Golden bandicoots can control insect populations that are considered pests by humans, such as cockroaches, termites and ants. Golden bandicoots are important prey items to native and non-native predators. As a result of their diet, they control some insect populations that are considered pests by humans, such as cockroaches, termites and ants.
Golden bandicoots also disperse seeds of certain plants they eat. Golden bandicoots are omnivorous. Their diet mainly consists of insects such as termites, ants and other arthropods. They also eat a variety of arachnid species. Golden bandicoots have been known to prey upon turtle eggs and small reptiles. Additionally, they consume plant material, usually consisting of seeds, roots, and tubers.
Golden bandicoots, Isoodon auratus , are endemic to Australia. They were historically found throughout the interior of Australia but are currently restricted to very small areas of Western Australia and the Northern Territory.
Golden bandicoots occupy a variety of habitats. They can be found in dry savannah habitats with an acacia or eucalyptus overstory, and they also colonize vine thickets.
They occupy coastal scrub areas as well as rainforest margins and sometimes occupy rocky, sandstone and spinifex areas.
Historically, golden bandicoots occurred throughout Australia in arid and semi-arid regions. Golden bandicoots are the smallest of the short nosed bandicoots, weighing between and g with measuring on average mm in length. Males are generally larger than females.
These marsupials have a compact body, sharp claws and a long nose. Their fur is brownish gold and is streaked with black on the upper and side parts of the body. The abdominal region and feet are a light amber color. The hairs of the fur are very course and stiff. The tail is long and sparsely haired. Golden bandicoots have rounded ears, and their eyes are very dark in color. They have a hunched overall body posture and are rat-like in appearance.
Predators of golden bandicoots mainly consist of non-native species that were introduced to Australia, such as red foxes and feral cats. Dingos and domestic dogs also prey upon golden bandicoots. Other native predators of golden bandicoots include reptiles such as pythons and monitor lizards , as well as northern quolls , scaley-tailed possoms and rock ringtail possums. Golden bandicoots breed throughout the year. Males and females mate briefly, and the male disperses after copulation.
Gestation lasts about 2 weeks. Offspring are very small when born, and litters consist of 2 to 4 individuals.
Females nurse their young for about 8 weeks and can begin to mate shortly after the young have weaned. Juveniles become sexually mature around 3 months of age. Golden bandicoots reproduce as many times as they can during their short lives, and there is a significant increase in reproduction during seasons with high rainfall.
Male golden bandicoots disperse after copulation and do not contribute to raising offspring. Females provide milk to their young, which are weaned by 8 weeks of age. The golden bandicoot Isoodon auratus is a short-nosed bandicoot found in northern Australia. It is the smallest of its genus. The golden bandicoot is now a threatened species. It is distinguished from the brown bandicoots by its golden colouring and much smaller size. It averages about 35 cm or 14 in.
The sides and face are a faded light rust colour, and the underbelly is pale amber. The feet are the same colour as the underbelly and have sharp claws.
The species was first described in from a specimen collected near Derby, Western Australia. It is an omnivore , consuming succulents , insects, plant bulbs, and small reptiles. The golden bandicoot is nocturnal, foraging at night by digging small holes in the ground to find food. The largest golden bandicoot population lives on Barrow Island because no cats or foxes have been introduced to the island, [5] and other populations exist on Middle, Marchinbar, Augustus Islands.
Recent genetic evidence suggests that the not only is the golden bandicoot I. These two appear to have been allopatric ever since the Pleistocene , long before the arrival of Europeans. In the s, the golden bandicoot was well spread throughout central Australia, but by the only populations on the mainland remained in the Prince Regent National Park in the Kimberley region.
The golden bandicoot lives in spinifex and tussock grasslands, [5] [6] and it used to be widely distributed in arid deserts and the surrounding semi-arid areas as well as tropical forests and woodlands. In Northern Kimberley, it is found along the margins of rainforests lined with sandstone, and in the Yampi Peninsula it inhabits eucalypt woodlands.
Individuals have a home range between 12—35 hectares , and the largest golden bandicoot population is on Barrow Island with about 20, individuals. The golden bandicoot is quite rat-like in appearance due to its small body, hunched-over posture, and relatively long tail.
The hind limbs are large and muscular compared to the short forelimbs. Each forefoot has three toes with flat claws, used for digging holes when hunting for prey. And, unlike most marsupials, the golden bandicoot has fused toes on its hind feet, forming a comb they use for grooming.
All bandicoots in the genus Isoodon have short noses and small, rounded ears, and thus can be distinguished from most other bandicoots, which have longer noses and larger ears.
