Indigenous knowledge key to saving goannas from cane toads
Author: Liam Taylor
A scientific team is collaborating with indigenous communities in the Kimberley’s to protect one of Australia’s most iconic animals. The team of conservation biologists from the University of Sydney has found success in a training method aimed at reducing goanna mortality from eating cane toads.
Over the past four years the research group, with the help of indigenous rangers, has been testing training programs involving feeding goannas less poisonous toadlets to teach them not to eat the deadlier adults. Over an 18-month period, the team found that 56 percent of trained goannas managed to survive as opposed to just three percent of untrained lizards.
A key learning from the project is that the skills and knowledge of Indigenous peoples has been vital to its success. Indigenous rangers are capable of finding goannas that are much shyer and more cautious about new food than those that non-Indigenous scientists have been able to catch. Interestingly, it is these goannas that are best at learning not to eat the cane toads, making indigenous involvement absolutely crucial to the project’s success.
The Kimberleys were long free from the cane toads wreaking devastation to Australian native fauna in Queensland and the Northern Territory. The toxic toads reached Western Australia in 2015 and are now advancing across the Eastern Kimberleys at a rate of approximately 50 kilometres per year.
The toads have a huge impact on fauna in the areas they infiltrate, especially the predators that are often unwittingly poisoned after eating them. Head of the research team Georgia Ward-Fear said that the introduction of cane toads to new areas often resulted in declines in goanna populations of up to 90 percent.
