Artificial intelligence could become a new weapon in the fight against Australia’s burgeoning fox population, as technology is developed to identify the invasive predators and deliver poison while sparing native wildlife.
uncertain
technology → become → wildlife
The push comes as a new federal strategy lays bare the scale of the threat from foxes, which occupy about 80 per cent of Australia and are estimated to kill more than 300 million native animals each year.
asserted
which → come → animals
The draft national threat abatement plan says AI-powered bait stations, image-recognition traps, thermal cameras and remotely monitored devices could make fox control more targeted and effective.
uncertain
control → say → ?
One system, known as a sentinel bait station, uses AI to distinguish between target and non-target animals and restrict access to bait.
asserted
system → know → bait
In some temperate areas, fox densities can reach 16 animals per square kilometre, from central Queensland, through NSW, Victoria and South Australia.
asserted
densities → reach → NSW
Populations are also now thriving in Western Australia.
asserted
Populations → thrive → Australia
The plan – which replaces strategy written almost 20 years ago – also examines improvements to grooming traps that use image recognition to identify animals before delivering a dose of poison.
asserted
that → replace → poison
Bluetooth technology could eventually prevent devices from firing at tagged domestic dogs, while mobile and satellite connections could allow rangers to monitor equipment remotely.
uncertain
rangers → prevent → equipment
An initial field test of a prototype produced promising results, although no foxes were encountered during the trial and further testing is required before the technology can be considered for wider use.
asserted
technology → produce → use
The latest government estimates put Australia’s fox population at about 1.7 million, although officials warn the figure fluctuates with rainfall, food availability and other environmental conditions.
asserted
figure → put → rainfall
Introduced by wealthy settlers for hunting between 1845 and 1879, the European red fox is estimated to kill about 367 million mammals each year, including 108 million native mammals, as well as 111 million birds and 88 million reptiles.
asserted
fox → introduce → mammals
They have contributed to the extinction of at least 20 native mammal species.
asserted
They → contribute → species
Invasive Species Council rewilding manager Rob Brewster said the new strategy was an opportunity to bring Australia’s approach to fox control into line with advances in conservation science.
asserted
strategy → say → science
“Foxes have helped drive native animals to extinction and continue to prey on threatened mammals, birds and reptiles across huge areas of the country,” he said.
asserted
he → help → country
“For animals like bandicoots, bettongs and many ground-dwelling birds, controlling foxes can be the difference between populations recovering or disappearing altogether.”
asserted
populations → dwell → foxes
Brewster said emerging technology would need to be matched by sustained investment.
asserted
technology → say → investment
“It is good to finally see a new national strategy on the table, but the final plan needs to be ambitious and backed by the funding needed to deliver real action on the ground,” he said.
asserted
he → see → ground
“A strategy sitting on a shelf won’t protect wildlife.
asserted
strategy → sit → wildlife
Governments need to invest in co-ordinated, sustained fox control across the landscapes where our most vulnerable native animals still survive.
asserted
animals → need → landscapes
The draft plan says foxes can rapidly recolonise areas after control efforts stop, with individual animals recorded travelling as far as 300 kilometres.
asserted
animals → say → kilometres
More than 40 fenced wildlife havens covering about 850 square kilometres have been established on the mainland to protect threatened mammals from foxes and feral cats.
asserted
havens → fence → foxes
Conventional control programs have helped reverse declines in species including the boodie, woylie, bridled nail-tailed wallaby and western swamp tortoise.
asserted
programs → help → boodie
But the government’s strategy envisages a combination of poisoning, trapping, shooting, exclusion fencing and eradication from priority islands, alongside research into emerging approaches.
asserted
strategy → envisage → approaches
Hamish McIntyre, the president of the National Farmers Federation, said foxes were a “dreadful pest” particularly for lambs and kid goats but also in horticulture around grapes and berries.
asserted
foxes → say → grapes
“It needs to be co-ordinated effort, obviously farmers, but also all the national parks and crown land,” he said, adding that “local, state, and federal governments should work together”.
asserted
governments → need → ?
The draft strategy sets a 30-year goal of reducing fox impacts sufficiently to secure the long-term viability of affected native species.
asserted
strategy → set → species
Dr Bronwyn Hradsky, from the school of agriculture, food and ecosystem sciences at the University of Melbourne, said no country had the tools to eradicate foxes at a continental scale.
asserted
country → say → scale
“With current methods, it is feasible to eradicate foxes from a confined space such as a fenced reserve or an offshore island but impossible over vast areas,” she said.
asserted
she → eradicate → areas
She said eradicating foxes from Australia would require some yet-to-be-developed form of biological control.
asserted
eradicating → say → control
Brewster said Australia had developed effective tools for controlling introduced predators but needed to deploy them at a much greater scale.
asserted
Australia → say → scale
AI is not presented as a replacement for existing control methods, but as a potential way to make them more precise, particularly in remote areas where monitoring traps and preventing harm to non-target animals can be difficult.
asserted
monitoring → present → animals
