Red foxes (Vulpes vulpes) are a significant conservation problem in Australia, with more than 7.2 million in the country as of 2012. They are found in suburban areas and large cities, including Perth in Western Australia. Foxes are considered pests in Western Australia under the Biosecurity and Agriculture Management Act 2007, and they are known to prey on free-range poultry, young lambs, and kid goats, as well as native birds, reptiles, and marsupials. To control the fox population, the Western Australian state government conducts aerial and hand baiting on almost 35,000 square kilometres as part of the Western Shield pest management program.

What You'll Learn
Foxes are a conservation problem in Australia
Foxes are a problem for conservationists as they prey on native species, causing their decline and even extinction. The red fox is a highly adaptable species, thriving in both rural and urban environments. They are found in high concentrations in suburban areas and large cities, such as Melbourne and Perth. Their presence in these areas has been linked to the decline of several native terrestrial marsupials, including the brush-tailed bettong, the numbat, and the quokka. Foxes also cause economic losses by preying on free-range poultry and young lambs.
In Western Australia, the red fox is a declared pest under the Biosecurity and Agriculture Management Act 2007. The Western Australian conservation department, CALM, estimates that introduced predators like the fox are responsible for the extinction of ten native species in that state. Research has shown that the presence of dingoes decreases the presence of foxes and increases native fauna. As such, the reintroduction of competitive species has been suggested as a method of control.
Fox management programs have been implemented in Western Australia to protect native species. These include baiting, trapping, and shooting. Aerial baiting is the most efficient technique, as it can be used in remote and inaccessible terrain. Remote camera monitoring is also used to assess the response of fox populations to these management strategies.

Foxes are found in suburban Perth, Western Australia
In Western Australia, red foxes are a declared pest under the Biosecurity and Agriculture Management Act 2007. They are implicated in the extinction and decline of numerous native animal species, including the desert rat-kangaroo, the brush-tailed bettong, the burrowing bettong, the rufous bettong, the Greater bilby, the numbat, the bridled nailtail wallaby, and the quokka. Foxes cause economic losses by preying on free-range poultry, lambs, and kid goats, and they have been found to scavenge waste food and steal pet food in urban areas.
Foxes are also found in suburban areas of Perth, where they have been studied using GPS-tracking. They are attracted to high-density residential areas and have learned to climb trees to hunt birds and other creatures, such as baby koalas. Fox baiting has been an effective method of reducing fox density in Western Australia, with aerial baiting being the most efficient technique due to the vast and remote terrain.
The Western Australian state government conducts aerial and hand baiting on almost 35,000 square kilometres to control foxes as part of the Western Shield pest management program. Fox management is crucial for the successful reintroduction and recovery of native fauna populations in Western Australia.

Foxes are a declared pest in Western Australia
In Western Australia, the red fox is a particular threat to significant native species such as the chuditch, woylie, and numbat. The Western Australian conservation department, CALM, estimates that introduced predators like the red fox are responsible for the extinction of ten native species in the state. The spread of the red fox population corresponds directly with the declining populations of several endemic terrestrial marsupials, including the brush-tailed, burrowing, and rufous bettong, the Greater bilby, numbat, bridled nailtail wallaby, and the quokka.
Foxes cause economic losses for farmers by preying on free-range poultry and, occasionally, young lambs and kid goats. While most lambs die from natural causes such as starvation, foxes often feed on the carcasses, and some do kill healthy lambs, causing serious losses for farmers. Foxes in urban areas have also been known to scavenge waste food, steal pet food, and kill backyard poultry.
The Western Australian government has recognised the impact of foxes and declared them a pest under the Biosecurity and Agriculture Management Act 2007. The Western Shield pest management program includes aerial and hand baiting on almost 35,000 square kilometres of land to control fox populations. Recent research in southwestern Western Australia has shown that fox baiting can reduce fox density by up to 80%. Other management tools used to control foxes include trapping and shooting.

Foxes are implicated in the extinction of native species
Red foxes (Vulpes vulpes) were introduced to Australia in the 1830s by European settlers. They are now found throughout most of the continental mainland, including Western Australia. Foxes have been directly implicated in the extinction and decline of native species in Western Australia. The West Australian conservation department, CALM, estimates that introduced predators, including foxes, are responsible for the extinction of ten native species in the state.
Foxes have been particularly detrimental to the family Potoroidae, which includes the desert rat-kangaroo. The spread of the red fox population corresponds with the declining populations of several endemic terrestrial marsupials, including the brush-tailed, burrowing, and rufous bettong, the Greater bilby, numbat, bridled nailtail wallaby, and the quokka. These species now only survive in limited areas, such as islands, where foxes are absent or rare. Foxes have also been known to prey on free-range poultry, lambs, and kid goats, causing economic losses for farmers.
The impact of foxes on native species in Western Australia is so significant that the state government has implemented pest management programs, such as the Western Shield program, which conducts aerial and hand baiting on almost 35,000 square kilometres to control fox populations. The success of these programs has allowed populations of native mammals to increase in managed areas, such as the chuditch, black-flanked rock wallaby, and woylie.
While some researchers argue that the presence of foxes may have benefits, such as suppressing the number of rodents, rabbits, and feral cats, the overall consensus is that foxes have had a detrimental impact on native species in Western Australia. Their efficient predation and rapid spread have made them one of the most damaging invasive species in the region, altering the ecological processes and leading to the decline and extinction of native mammals.

Fox baiting is used to reduce fox density
Red foxes (Vulpes vulpes) are a serious conservation problem in Australia. Foxes have been implicated in the extinction and decline of many native Australian mammal species, including the desert rat-kangaroo, the brush-tailed bettong, the burrowing bettong, the rufous bettong, the Greater bilby, the numbat, the bridled nailtail wallaby, and the quokka. Foxes also cause economic losses by preying on free-range poultry and livestock such as lambs and kid goats.
Fox baiting is the most effective method of reducing fox density and impact on wildlife and livestock. It is a landscape-scale control tool that can provide 24-hour control, as baits sit in the landscape waiting for foxes to pick them up. In Australia, two toxins are approved for use in fox control: 1080 (sodium fluoroacetate) and PAPP (para-amino propiophenone or para-aminopropiophenone). 1080 is derived from a naturally occurring compound found in some native Australian plant species, and some native wildlife species have built a tolerance to it. PAPP is a newer toxin for baiting foxes in Australia, and while it is effective against carnivores such as foxes, dogs, and cats, it can also be toxic to other species. Therefore, it is important to avoid baiting when non-target species may be at risk and to bury fox baits during baiting to reduce non-target species access.
The optimal baiting rate depends on the home range size and density of foxes in the area. Baiting programs can be targeted and strategic, utilizing local knowledge and monitoring results to determine the optimal baiting rate. If the aim of baiting is long-term control, regular baiting needs to be carried out across an entire region with 2 to 4 pulses per year. Baiting can also be used to reduce the impact of foxes at critical times, such as during the lambing season or the vulnerable stage of a native animal's lifecycle. For example, baiting 6 to 8 weeks before the anticipated impact can help protect nestling chicks. Additionally, pulse-baiting can be considered for extended baiting periods (more than one month) to reduce the potential for non-target damage and increase cost efficiency.
In Western Australia, the state government authorities conduct aerial and hand baiting on almost 35,000 square kilometers as part of the Western Shield pest management program to control foxes and feral cats. Fox baiting is a strictly regulated activity in Australia, with legislation restricting the use of some baits and methods in certain jurisdictions. Training and permits are often required, and it is important to inform neighbors and display signs when using toxins like 1080, which has no antidote and can be harmful to working dogs and pets.
