The authority that recommended this species for an ex situ program

NSW Office of Environment and Heritage

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?

Yes

Name of the institution managing the ex situ population

ZAA institutions

Year the program started

2003

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

Yes

Are sufficient resources available to manage the ex situ population?

Yes

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

Yes

Is sufficient space available for the required population size?

Yes

Additional Support required

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

Yes

Taxon Management Coordinator

Michael McFadden of Taronga Zoo

Has a Taxon Management Group or Recovery Team been established?

Yes

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

Yes

Web link to Taxon Management Plan

Have Husbandry Guidelines been written?

Yes

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?

Yes

List of knowledge gaps

How to improve resistance of individuals to Chytrid fungus.

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

Yes

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

Yes

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

Yes

What tools are used to maximize retention of genetic diversity?

Others

Has the population produced viable offspring?

Yes

Have the first generation captive-bred animals bred successfully?

Yes

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

Yes

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?

Yes

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

Yes

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

Yes

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

Yes

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?

No

Comments

Participating institutions: Tidbinbilla Nature Reserve, Taronga Zoo, Healesville Sanctuary. This species has made in excellent progress in recent years with successful captive breeding and the first reintroduction efforts. This has included the release of approximately 200 frogs from Tidbinbilla Nature Reserve and the release of approximately 600 eggs and tadpoles from Taronga Zoo.
