In short
A $28 million attempt to stop cane toads invading the Pilbara will see a 7,500-square-kilometre "waterless barrier" constructed south of Broome.
asserted
barrier → stop → Broome
The plan involves modifying water points across six pastoral stations in Western Australia's north to stop the toads spreading.
asserted
toads → involve → north
Rio Tinto is fully funding the Toad Containment Zone project, in partnership with Curtin University, with works starting in 2027.
asserted
works → fund → 2027
The latest bid to halt the ongoing cane toad invasion of northern Western Australia is set to begin after final funding and approval.
asserted
bid → halt → funding
The current estimated front line of the toad's spread has the pests around 100km from Broome, 2,200km north of Perth.
asserted
line → estimate → Perth
Scientists are now hoping a "waterless barrier" across WA's northern Pilbara will help halt the further spread of the invasive species.
asserted
barrier → hop → species
The barrier proposal, to be implemented south of Broome, will see artificial watering holes such as dams and storage tanks cut off, in turn removing the toads' water supply.
asserted
holes → implement → supply
This project involves modifying water points across six pastoral stations, which cover 7,500 square kilometres of land.
asserted
which → involve → land
An additional $28m funding injection from Rio Tinto and the Rhodes Ridge joint venture will see official work on the containment zone start next year.
asserted
work → see → zone
The toads have already killed millions of Australian native animals, ranging from snakes to goannas and crocodiles.
asserted
toads → kill → goannas
"The loss of these animals from across that landscape is a national tragedy and it's a loss of natural heritage and cultural heritage for Indigenous landowners," Curtin University biologist Ben Phillips said.
"The Pilbara is another region of Australia chock-full of plants and animals found nowhere else on the planet.
asserted
Pilbara → say → planet
Cane toads will thrive in the Pilbara."
asserted
toads → thrive → Pilbara
Professor Phillips said the project represented the best opportunity to prevent the worst from happening.
asserted
project → say → worst
Curtin University ecologist Judy Dunlop said toad-proofing water points had proven successful in other locations.
asserted
points → say → locations
"By removing the critical thing they need, which is water, we prevent them from continuing their spread," Dr Dunlop said.
asserted
Dunlop → remove → spread
"The build itself will take the next two to five years and we will be doing a lot of work on the sidelines as well as monitoring animals."
asserted
we → take → animals
Protecting native wildlife
Karajarri Traditional Lands Association chief executive Martin Bin Rashid said traditional owners had been consulted throughout the process.
asserted
owners → protect → process
"We've got a ranger program, we have a heritage team that are going to assist the project leads and construction workers," he said.
"Making sure we also look after those special water holes that hold significant stories and Dreamtime stories for our people and give life to country."
asserted
that → get → country
"It's a big station so there's plenty of water points; it ends up being about 100 waterless barriers," Anna Plains Station owner David Stoate said.
asserted
Stoate → be → points
"It took a bit of time to come around to the idea of the project because it's such a big job.
asserted
it → take → project
"A journey of 1,000 miles starts with a single step, so that's very much what we're doing with this project."
asserted
we → start → project
Funding commitment
The waterless barrier proposal has been floated since 2016, with the Barnett Liberal-National government at the time allocating about $340,000 in funding for community consultation.
asserted
government → float → consultation
Funding for the conservation initiative initially reached $12 million, with the Rio/Rhodes Ridge contribution, to be allocated over five years, more than doubling that figure.
asserted
contribution → reach → figure
Rio Tinto's Chris Osborn said the Pilbara was a special place and important to protect.
asserted
Pilbara → say → ?
"I think it's a model for how really critical problems can be solved when you get the right partners involved," he said.
asserted
he → think → ?
"Science-based solutions with practical input from traditional owner groups, from pastoralists, [that] will help this project be a success."
asserted
project → base → pastoralists
