Rio Tinto creates ‘kill zone’ to halt cane toad invasion

TL;DR

  • Rio Tinto is investing A$28 million ($20 million) to combat cane toad encroachment in Western Australia's Pilbara region.
  • A 'kill zone' is being established between the Indian Ocean and the Great Sandy Desert to prevent the toads from reaching the Pilbara.
  • The invasive toads threaten local biodiversity, including reptiles, ghost bats, quolls, and little red kalutas, potentially increasing mining compliance costs.
  • The strategy involves making approximately 200 water sources in a 40km by 400km containment area toad-proof.
  • Cane toads also pose a cultural threat to indigenous populations by diminishing traditional food sources like goannas.
  • The toads are projected to reach Broome in about two years and the Pilbara region by 2045.
  • The initiative is a collaboration between Rio Tinto, scientists, farmers, and the local indigenous community.
  • This approach focuses on adapting the environment to make it uninhabitable for toads, rather than directly targeting the animals.
