Wallum frogs is the collective term applied to a suite of frog species that are found only in wallum/heath environments. These environments are characterised by vegetation such as Melaleucas, sedges and banksias. The waters in these swampy areas are tannin-stained and of a low pH due to the dissolved organic acids.
My friend Kat (of crayfish fame) is now doing a PhD looking at factors that influence the distribution of these wallum froggies. I went out with her on Friday night to have a bit of a poke around. I’d never explored any wallum country, so I was happy to see the three species that we were hoping for (plus one ubiquitous foreigner).
