Protecting Biodiversity Through Innovative Containment Measures
BHP (ASX: BHP) is collaborating with Curtin University to fund a groundbreaking project aimed at preventing the spread of cane toads in Western Australia’s Pilbara region. These invasive species have been present in northern Pilbara since 2009, posing a significant threat to local biodiversity and culturally significant sites.
To mitigate this risk, Curtin University researchers propose establishing a 150km containment zone between Broome and Port Hedland. The strategy involves cutting off toad access to artificial water sources such as cattle watering tanks and troughs. This “waterless barrier” is expected to protect over 26 million hectares of WA from cane toad infestation.
Long-Term Impact on Conservation and Wildlife
Curtin’s research suggests that effective management of artificial water sources could delay the cane toad invasion by over 50 years. This would safeguard endangered native species like ghost bats and northern quolls while preventing ten additional species from becoming classified as threatened or at risk.
BHP WA community manager Rachel Donkin emphasized the project’s broader significance: “Protecting the Pilbara’s native wildlife and ensuring important community and Indigenous environmental sites are preserved for future generations is a key priority of our social investment program.”
Researchers will also analyze potential toad adaptations, including their ability to jump containment barriers, survive in Bilby burrows, and endure extended periods without water. With cane toads currently less than 150km from Broome and expected to reach the containment zone by 2028, Curtin University professor Ben Phillips stressed the urgency of action.
The research project is set to conclude by September 2025, incorporating key management refinements to enhance its long-term effectiveness in protecting WA’s ecosystems.
