Population stable in wild


Spicospina flammocaerulea

Common Name(s)

Sunset Frog

Region where program is based


Country where program is based


The authority that recommended this species for an ex situ program

Department of Conservation and Land Management

Has a genetic analysis been performed on wild populations to define the target taxon, i.e., verify that single, viable Evolutionarily Significant Units (ESU's) that are managed as separate populations, are not confounded by cryptic species or polymorphisms?


Name of the institution managing the ex situ population

Perth Zoo

Year the program started


Is at least some portion of the captive population maintained in range country?


Are sufficient resources available to manage the ex situ population?

Are adequate numbers of skilled staff available with the appropriate ex situ amphibian experience?

Is sufficient space available for the required population size?

Additional Support required

Has a Taxon Management Coordinator for the ex situ population been appointed?


Taxon Management Coordinator

Kay Bradfield of Perth Zoo

Has a Taxon Management Group or Recovery Team been established?


Names and institutions of Taxon Management Group members

Perth Zoo, Department of Environment and Conservation, University of Western Australia

Has a Taxon Management Plan, Recovery Plan or Species Action Statement been written?


Have Husbandry Guidelines been written?


Web link to Husbandry Management Guidelines

Have any knowledge gaps in the species biology or in their interaction with potential threats been identified that could benefit from research using the ex situ population?

Have founder needs been calculated using the AArk Amphibian Population Management Guidelines ?

Have sufficient potential founders been collected? ( AArk Amphibian Population Management Guidelines recommends a minimum of 20 pairs of found animals).


Is the ex situ population managed by nationals from the range country?


What tools are used to maximize retention of genetic diversity?

Has the population produced viable offspring?


Have the first generation captive-bred animals bred successfully?


Is the ex situ population housed in permanent isolation from other populations occurring outside its range?


Is work being supported to study and mitigate threats to the species in the wild, either by the institution or by a regional wildlife agency?


Have captive-bred or captive-reared animals been released into the wild?


If releases were undertaken, have disease screening protocols or veterinary health checks been conducted prior to releases to the wild?


Is follow-up work being carried out to monitor progress of the released animals?


Is the taxon again secure in the wild, even if it might still require some ongoing in situ management? i.e. has the need for a captive assurance population been obviated such that we can call this a successfully terminated captive rescue program?



22 head-started adults and 251 captive bred tadpoles were all released to the wild prior to reaching sexual maturity. Animals head-started from eggs did breed successfully at Perth Zoo. Populations are currently stable, although climate change may be an issue in the future. This program was not intended as a captive rescue program; the purpose was to determine how to successfully breed and rear individuals in case it is necessary to undertake a full scale breeding or head-starting program at a later date.
