How many eastern barred bandicoots are left in the world

Challenge Once common, the Eastern Barred Bandicoot is now one of Victoria's most endangered species and considered extinct in the wild.

Long-Term Impact This project will allow hectares of protected grasslands to become habitat for Eastern Barred Bandicoots, doubling the current endangered population - critical for their survival. Donate once. Donate monthly. Several cameras are needed to cover vast areas of grasslands - the cameras will also help monitor predators.

Terms and conditions apply. Give the gift of stability in a time of instability. Monthly giving is as easy, safe, and as inexpensive as a Netflix subscription. And she said it was not just the species that had benefited from three decades of work. They're digging for foods, so worms and beetle grubs," Dr Coetsee said. We acknowledge Aboriginal and Torres Strait Islander peoples as the First Australians and Traditional Custodians of the lands where we live, learn, and work.

Key points: Eastern barred bandicoots remain an endangered species but are surviving in the wild It's estimated around 1, bandicoots are living at protected sites and reserves around Victoria Successful conservation efforts have allowed Zoos Victoria to end its year captive breeding program.

A project to determine the extent and impact of Toxoplasma disease from feral cats and feral rabbits is being conducted on Phillip Island and French Island commencing This will look at the extent of Toxoplasma gondii within populations of feral cats and the spread of the disease in the soil. This project will greatly assist in the understanding of how this disease can impact on Eastern Barred Bandicoots and ensure the selection and management of new release sites avoids potential problems.

Research being conducted by Kath Adriaanse, University of Melbourne. A research project by Lauren Halstead, Deakin University is aimed at investigating the role Eastern Barred Bandicoots play as ecosystem engineers. The research is based on the Churchill Island population. Measurements of soil turn over, soil moisture, soil strength and chemistry are being collected. This research will assist in obtaining further ecological information about Eastern Barred Bandicoot digging which is thought to assist in maintaining higher moisture levels within the soil.

Rachel Taylor, University of Melbourne is undertaking research to determine if Eastern Barred Bandicoots can be trained to recognise cats as predators. The success of the recovery program to-date has been achieved through co-operation between Parks Victoria, Conservation Volunteers, Zoos Victoria, Department of Environment and Primary Industries, National Trust and Mt Rothwell Conservation Centre who have worked together to secure remnant populations, increase the captive population and create new predator proof areas for releases that will provide additional security for this species into the future.

The workshop highlighted the need to establish multiple open-range populations, managed as meta-populations, and the establishment of larger populations. Zoos Victoria is using genetic analysis of captive and open-range populations to select new animals for captive breeding. Zoos Victoria - Fighting extinction program has been fundamental to saving the Eastern Barred Bandicoot from extinction. Captive breeding has been carried out at the zoo with 36 breeding pods established to assist in captive breeding success.

The Eastern Barred Bandicoot is capable of giving birth to up to five joeys five times a year with an average of joeys each time.

So if conditions are right the population can quickly expand. A significant project at Werribee Open Range Zoo has been the completion of predator proof fencing which now provides opportunity for Ha of secure predator free habitat. Work has been undertaken to optimise habitat for the Eastern Barred Bandicoot, which includes ripping rabbit burrows, treating the enclosed area to remove foxes and feral cats and restoration of grassland habitat.

There is a 5 year strategy to remove rabbits, improve native grassland habitat and gradually reintroduce bandicoots as habitat improves.

Thousands of rabbits were removed through the baiting program. Releases into the predator free areas commenced in late with releases of small numbers planned for 5 different predator free areas within the Zoo during and beyond. These Eastern Barred Bandicoots will not be as intensively managed by Zoo keepers but a regular trapping program will enable keepers to monitor their condition.

In Werribee Zoo completed construction on new roofing for their 36 breeding enclosures. These two animals are doing an important job advocating this elusive species to visitors and VIPs. The Werribee Open Range Zoo is also conducting pairing, mate choice preference trials involving about 20 Eastern Barred Bandicoots to maximise the reproductive success.

Results released in indicate that females are choosing mates, and those paired with their preferred males had a shorter time to pregnancy and more pregnancies than other females. A program to use Maremma dogs to protect Eastern Barred Bandicoots from foxes is being developed. The use of guardian dogs could be a valuable tool to protect bandicoots from foxes and cats and has the potential to expand the number of release sites which is currently limited to sites that have predator proof fencing.

The Hamilton Community Parklands reserve contains a ha fenced off fox proof area. Population monitoring has been conducted at this site for many decades. Since a more intensive monitoring program has operated with monitoring three or four times per year. In the population was around bandicoots which is higher than previously estimated but may have reached animals in The population at Hamilton Community Parklands reserve is known to fluctuate considerably with adequate rainfall being a major factor in breeding and holding capacity.

The impact of foxes even one or two though the fence can have dramatic consequences on the population. Despite checks of the predator proof fence 3 times per week foxes were detected breaching the fence in April The access points were identified and sealed off and three foxes removed by May. This was the first time foxes entered the area since Two harvests of 10 animals each were undertaken in to support a trail release at French Island and also support Zoos Victoria captive breeding program.

Other works in the broader Hamilton Community Parklands included rabbit warren destruction work funded by DEPI, destroying approximately 20 warrens through the Hamilton reserve, which have been subsequently replanted with grassland species by Conservation Volunteers. Environmental weed management across site to remove gorse and pittosporum was undertaken as well as burning for fire protection and grassland management conducted in January Between and there were difficulties regarding predator control as foxes entered through protective fencing impacting on the population.

During , Conservation Volunteers Australia undertook on-ground management of the reserve. With the help of dedicated volunteers, the Glenelg Hopkins CMA and the community the predator proof fence was upgraded and foxes removed. These bandicoots are doing well in their new fox free environment. See the release at Hamilton Community Parklands. In November there were very pleasing results from the population monitoring with 20 bandicoots trapped, including 5 new animals that were offspring from the April releases.

In addition all females caught had pouched young which is a good sign of successful breeding. Mt Rothwell is a ha area of private land dedicated to conservation and is home to the Mount Rothwell Biodiversity Interpretation Centre.

Eastern Barred Bandicoots were first released at Mt Rothwell in Their numbers have steadily grown within the predator proof fence area. In the population was competing against an increasing rabbit population due to abundant grass cover but natural predation from native predators combined with a rabbit control programs has seen the Bandicoot population continue to rise from an estimated animals in to animals in During a single breeding season a female may produce litters with a litter size of young.

Thus a female bandicoot can potentially give birth to as many as 16 young in one year! By way of comparison, rabbits give birth to between 11 and 25 young per year, depending on environmental conditions. Although the eastern barred bandicoot has a very high reproductive rate, mortality - particularly among juveniles - is extremely high.

The causes of mortality are not well known, but predators and disease appear to be the main agents. The life-span of the eastern barred bandicoot is less than 3 years.

Eastern barred bandicoots spend their day resting in nests. These are usually no more than a shallow depression in the ground with a dome of grass pulled over the top. Only one adult bandicoot occupies a nest, although young may share the nest with their mother for a week after they first leave the pouch.

After dusk, they emerge and immediately begin foraging for food.
