Australia’s Native Frogs Fight With Cane Toads Successfully

argylesock says… The green tree frog (Litoria caerulea) is native to Australia and it used to be common. But its populations have declined. Pollution and habitat loss are blamed. Richard Shine of Sydney University led the team which now reports L. caerulea outcompeting the invasive cane toad (Rhinella marina). Prof Shine says, ‘If we can encourage native frog populations back into suburban areas where they once occurred, they will be able to reduce survival and recruitment of cane toads from those same ponds.’ I like the idea of tackling the cane toad problem by ‘encouraging’ native frogs, but I wonder how feasible that would be in reality.

BBC News2013-03-07: The tadpoles of Australia‘s native frogs can outcompete invasive toads, scientists say. The toads are considered a threat to Australian wildlife, leading researchers to investigate methods to control their population. A study into competition between wild amphibian young revealed that the presence of green tree frogs reduced cane toad survival. Experts now suggest reintroducing the familiar frogs to suburban areas. The results are published in the journal Austral Ecology. Cane toads are native to South America but were introduced to Australia in 1935 to control sugar cane pests. Continue reading the main… more »

About argylesock

I wrote a PhD about veterinary parasitology so that's the starting point for this blog. But I'm now branching out into other areas of biology and into popular science writing. I'll write here about science that happens in landscapes, particularly farmland, and about science involving interspecific interactions. Datasets and statistics get my attention. Exactly where this blog will lead? That's a journey that I'm on and I hope you'll come with me.

    Cane toads are a major problem, they’re everywhere, so this is some welcome news.

      Yes it is. When I first saw Ann’s post, I wrongly thought that she meant that somebody proposed to introduce yet another alien species. Biological control to tackle the disaster of another biological control attempt. But no, that’s not what is proposed. This is about ‘encouraging’ a native species (the green tree frog) to overcome the invasive alien species (the cane toad).

      I haven’t yet seen any suggestions about how to ‘encourage’ green tree frogs.
