Growling Grass Frog Sub-regional Species Strategy

Our team was commissioned by the Department of Environment, Land, Water and Planning (formally DSE) to prepare technical details and guidelines for a Sub-regional Species Strategy for the nationally threatened Growling Grass Frog Litoria raniformis, to meet the requirements of the Melbourne Strategic Assessment Program, (under the Environment Protection and Biodiversity Conservation Act 1999).

Ecological reviews, habitat assessments and targeted surveys

The following ​were completed across Melbourne’s revised Urban Growth Boundary to inform the strategy:

  • Detailed literature reviews
  • Diurnal surveys and habitat assessments
  • Roadside census
  • Nocturnal surveys for the species at selected sites


Our surveys 


  • Identified areas across Melbourne's Growth Corridors to be protected and managed for Growling Grass Frog  
  • Determined the distribution of Growling Grass Frog and habitat quality at occupied and unoccupied sites
  • Identified strategically important habitat areas/linkages
  • Provided guidelines for conservation to ensure the long-term viability of the species


Outcomes and benefits

Our detailed investigations and future protection and management recommendations underpinned the preparation of the final Growling Grass Frog Sub-regional Species Strategy. The Strategy, which was subsequently approved by the Commonwealth Government under Part 10 of the Environment Protection and Biodiversity Conservation Act 1999, is a guide to protecting the Growling Grass Frog from present and future impacts and threatening processes from urban development, with the primary objective of long-term population viability.

This project included the Melbourne Water service area and we now have an intimate understanding of the current distribution of the species, key threatening processes and management strategies determined for the long-term protection of the species.
