Green and Golden Bell Frog Monitoring

Monitoring of the nationally threatened Green and Golden Bell Frog Litoria aurea at Sydney Olympic Park, Homebush Bay, New South Wales

Our team of Zoologists undertook detailed population and habitat monitoring of the nationally threatened Green and Golden Bell Frog (GGBF) Litoria aurea at the Sydney Olympic Park, Homebush Bay, New South Wales.  The primarily objective of the monitoring was to assess the status of the population over several years, provide advice to Sydney Olympic Park Authority in relation to the appropriate management of the frog and its habitat, and to fulfil regulatory monitoring and reporting requirements.

The monitoring involved several contemporary frog survey methods including visual encounter surveys (spotlighting), auditory surveys, and tadpole surveys using both dip netting and innovative tadpole traps.  The team also conducted detailed mark-recapture surveys (demographic study) using small microchips otherwise known as Passive Integrated Transponders (PIT tags).  The purpose of this was to monitor trends in the population, to determine metamorph survivorship, and to obtain an insight into the movement and dispersal patterns across the site.
