Region where program is based

Europe

Country where program is based

Netherlands

The authority that recommended this species for an ex situ program

Conservation Needs Assessment Workshop, Conservation Needs Assessment Workshop

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

EAZA institutions

Year the program started

1999

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

No

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

Gerardo Garcia of Chester 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

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?

Yes

List of knowledge gaps

Numerous and mostly being addressed.

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?

No

What tools are used to maximize retention of genetic diversity?

SPARKS/PM2000

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

Founder frogs were rescued from Montserrat when chytrid arrived in 2009. F1 progeny have been returned to Montserrat under intensive observation to investigate the options for restoring Mountain Chicken populations even in the face of chytrid fungus infection. Three trial releases have been done so far, 2011 and 2012 with a total of 121 frogs.
