Green and Golden Bell frogs update

Client: VIVA Energy

Location: Clyde Terminal

You can feel the crunch of the land when you walk along the ground, the hot temperatures and the lack of rain has dried out the earth. But out at VIVA Energy at Clydes Terminal Hub everything is looking healthy and alive.  The restoration and rehabilitation for the Green and Golden Bell frogs (Litoria aurea) are coming along nicely, the weather has worked against us but in other ways it has worked for us.

To eradicate Mosquitofish (Gambusia holbrooki) has been a priority at VIVA, as they decline the population of the Green and Golden Bell Frog (GGBFs). The ponds water level are currently low at the moment due to the drought, the good news is it has been assisting in keeping the population of Mosquitofish down. The Mosquito Fish are reducing in numbers with the lack of water and the GGBF’s, eels and turtles have gone into hiding, waiting for the rain to fall and water level of ponds to increase.

The introduction of Mosquitofish (Gambusia holbrooki) in Australia was around the 1920’s, introduced by military and local councils to control mosquito populations. Brought in from North America the biological control for mosquitos was unsuccessful. However, they began a disturbance in the natural habitat of the GGBF and has decimated many of the amphibian population due to their aggressive behaviour preying on eggs and larvae of native fish and amphibians.

The construction of the new breeding ponds out at VIVA are complete and will create a significant amount of water for the GGBFs to populate since the water of the original ponds has dramatically reduced in size. Now we wait for the sky to open up and gift bring rain to fill up the ponds up for the frogs to start their breeding program, as we would prefer not to have to use the town water.

Managing and monitoring the weeds are still in place. Our staff are making great progress in cutting back around the perimeter of the ponds to allow more light penetration. Monitoring of Acacia pubescens is occurring. Limiting and reducing the population of the following weeds continues: Juncus acutus, Olea europaea, Ligustrum lucidum, Casuarina spp. and Cortaderia selloana along berm of wetland and annuals are being removed within the terrestrial areas.

Now bring on the rain and fill up the ponds.
