Mark is Head of Sciences at Museum Victoria. He's reporting back from Neds Corner in this series of blog posts.

By 25 November, rain drenched Neds Corner and the clay turned to slippery mud. Great weather for frogs. With the rain's arrival, frogs emerged from the mud as our vehicles sank into it.

Pobblebonk frogs turned up everywhere. In our pitfall trap lines, 30 pits contained 37 frogs. These frogs bury into the soil in the dry weather and wait for the rains. Then they emerge to feed and mate.

The other frogs we encountered were the Spadefoot, Spotted and Barking Marsh Frogs, Peron's Tree Frog and a froglet (genus Crinia). The tree frogs can be recognised by their padded toes, good for climbing.

The wetter weather was also good for the fungi and Dr Teresa Lebel from the National Herbarium of Victoria found many new records for this region. In arid country many types of fungus rest under the soil in a shrivelled state. As soon as the water reaches them, their stalks hydrate and the heads of species like puffball fungi emerge above the mud to release their spores.

One of the fungus highlights was finding fallen white shelf fungi at the bases of big River Red Gums. The spongy dead fungus is called Tinder Conch fungus as Aboriginal peoples used it for carrying the slow-burning coals needed for fire starting.

Our survey team was not as well-adapted as the frogs and managed to bog three cars in one day, but a combination of winches and effort got us all home safe and sound.

Bush Blitz is a biodiversity partnership discovery program between the Australian Government, BHP Billiton and Earthwatch Australia, that aims to document the plants and animals across Australia's National Reserve System. Museum Victoria also participated in Bush Blitz at Lake Condah in March 2011.
