Species

Epidalea calamita

Common Name(s)

Natterjack Toad, Sapo Corredor

Region where program is based

Europe

Country where program is based

Denmark

The authority that recommended this species for an ex situ program

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

Copenhagen Zoo

Year the program started

2008

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?

Additional Support required

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

Yes

Taxon Management Coordinator

Lene Vestergren of Copenhagen Zoo

Has a Taxon Management Group or Recovery Team been established?

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).

Yes

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

Yes

What tools are used to maximize retention of genetic diversity?

Has the population produced viable offspring?

No

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?

Yes

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?

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

In 2008, a newly laid Natterjack Toad egg string from Refsvindinge arrived at the Zoo. In 2009, the first pond was established on the grounds of a local landowner. By 2020, one pond has now turned into fifteen, and in total, more than 35,000 tadpoles and 1,100 toads have now been released in these ponds.
