Growling Grass Frogs in Darebin Creek Catchment
In 2021-22 citizen scientists monitored a number of sites for Growling Grass Frogs (Litoria raniformis) in the Darebin Creek Catchment. This involved the coordination of volunteers across the catchment to monitor through listening for calls during mating season and searching for frogs in the later summer months. DCMC analysed the data collected, historical population data and habitat condition records to determine population size and trajectory.
The analysis by the DCMC and the broader DELWP monitoring showed a decline in populations of L. raniformis and a trajectory towards regional extinction, underpinning the need for conservation action.
There will be ongoing annual GGF monitoring at these sites, 2022-23 will get underway from late October.
