The Large Brown Tree Frog

A chance check on a hollow log in far east Gippsland revealed a rare discovery and the possibility of improving the survival of an elusive frog.

The Large Brown Tree Frog (Litoria littlejohni) is listed as threatened under the Flora and Fauna Guarantee Act 1988, and in Victoria it has only been recorded at a small number of sites in East Gippsland.

So, DELWP staff were excited to be told about a pool of water in a fallen hollow tree that contained Large Brown Tree Frog tadpoles.

This pool was discovered by a naturalist from a local environment group and is the only active breeding site for the frog known in Victoria at the moment, with 15 to 20 tadpoles in the pool and reports of adult frogs heard in the area.

The log pool is a high-quality breeding site and local DELWP staff want to encourage more breeding in the area, so they’re trialling artificial structures nearby that replicate this type of habitat and hopefully support successful breeding for the frog.

DELWP is working with the Moogji Aboriginal Council Natural Resource Management Team on this project to construct the first artificial pond structures, handing over to their construction team to complete the rest.

It’s a simple design that can be put up in the bush, trying to replicate the fallen log pool habitat, using corrugated iron to catch water and funnel it into a tub containing river sand, rocks and logs to form a habitat that might attract frogs to breed.

In time, leaves will fall into the water, and algae and moss will build up, creating a little ecosystem of stable pools of water for the frogs to breed in.

The State Government’s Biodiversity On-Ground Actions is funding this trial program.
