Wallum Froglet (Crinia tinnula)



Species Action Statement

This species has been assigned to the Keep-watch species management stream under the Saving our Species program.

Justification for allocation to this management stream

These species require no immediate investment because they are either naturally rare, have few known threats, or are more abundant than previously assumed when they were listed as threatened.

Conservation status in NSW: Vulnerable
Commonwealth status: Not listed

Management objectives

This action statement aims to ensure the security of this species in the long-term.

Species sightings and management sites across NSW

How will this species be managed?

  • This species is likely to be secure in NSW for the long term without targeted management, assuming adequate ongoing management of habitat within the public reserve system. This species is therefore a lower priority for investment than other, more threatened species that have urgent management requirements. Any change in the status of this species (e.g. decline in abundance or emergence of a significant threat) will trigger a shift to the Site-managed stream and the development of a conservation project, which will be prioritised for implementation.
A number of state-wide conservation actions have also been identified for this species, which can be viewed by clicking the link below.

Show actions

  • Finalise preparation of national Wallum-dependent frog species Recovery Plan.
  • Qld Environment Protection Agency, NSW Department of Environment & Conservation and SE Qld Frog Recovery Team coordinate implementation of Recovery Plan.
  • Review status of species; determine whether Commonwealth listing on the EPBC Act is justified and prepare nomination if appropriate.
  • Map (and refine existing mapping of) potential habitat areas and group into habitat value categories.
  • Survey areas identified as potential habitat to determine presence/absence of target species, habitat condition, future management priorities and appropriate tenures.
  • Investigate, and where appropriate and landowners agree, implement relevant land protection and/or management mechanisms on freehold, leasehold and crown lands.
  • Rehabilitate or re-create former habitat degraded or destroyed by grazing, sand mining & other activities.
  • Create habitat in corridors linking existing or rehabilitated habitat.
  • Control, and where practicable, eradicate the Plague Minnow in accordance with approved Threat Abatement Plan..
  • Ensure regional fire plans and hazard reduction guidelines include protocols for protection of Crinia tinnula habitat.
  • Control stormwater runoff, drainage, ground water extraction and associated changes in water chemistry, pH, quality and quantity that may adversely impact on habitats and/or species' populations.
  • Control the invasion of weeds that may adversely impact on Wallum habitats.
  • Develop and implement measures to minimise the spread of the disease chytridiomycosis to and between habitats.
  • Control, and where practicable, eradicate feral pigs.
  • Monitor selected populations of C. tinnula to determine population trends and species' responses to threatening processes.
  • Monitor populations and habitat of sites before and after development to determine impacts of the developments and effectiveness of ameliorator measures.
  • Improve knowledge and understanding of aspects of the species' biology and ecology (e.g. non-breeding habitat use and population dynamics), taxonomy and genetics that are related to /or are impacted by conservation and management, habitat fragmentation.
  • Determine impacts of Plague Minnow on C. tinnula in accordance with the Gambusia Threat Abatement plan.
  • Determine impacts of pesticides and herbicides (from agriculture, weed and mosquito control, etc) on habitat and individual C. tinnula.
  • Investigate potential impacts of global climate change (particularly sea level rises) on habitat nature and extent.
  • Investigate impacts of current fire management practices on habitats and populations.
  • Investigate impacts of stormwater runoff, drainage, groundwater extraction and associated changes in water chemistry, pH, quantity and quality on species' habitats and/or populations.
  • Investigate the nature and potential degree of impacts of the disease chytridiomycosis on species' populations.
  • Determine most effective and cost-efficient monitoring and survey methods for the species for both recovery and proposed development impact assessment objectives.
  • Determine potential nature and extent of competition from other frog species following habitat modification or degradation.
  • Undertake ongoing assessment of effectiveness of current management strategies. Incorporate results of surveys, monitoring and research to develop more cost-efficient and effective management strategies.
  • Inform and involve the community, landholders and other stakeholders through the. production and dissemination of fact sheets on acid frogs, habitat management & protection, web page, survey/monitoring training workshops and displayboards.
  • Manage cane toads in areas of known habitat.
  • Protect swamps from fire.
