Acid Frog Habitat Management

Assessment of Wallum Sedge Frog pond hydroperiod | Acid Frog Management Plan


The proposed Caloundra South Urban Development Area incorporates threatened Acid Frog habitat. An assessment of the existing Wallum Sedge Frog pond hydroperiod was undertaken to ensure future constructed habitat ponds provide the correct hydraulic regime for colonisation and continued habitat post development. An Acid Frog Management Plan was completed to protect three Acid Frog species, all listed as vulnerable under the Nature Conservation Act, 1992, one also listed as vulnerable under the Environment Protection and Biodiversity Conservation Act,1999.
