Country where program is based

Ireland

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

Fota Wildlife Park

Year the program started

2019

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

Yes

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?

Yes

Taxon Management Coordinator

Sean McKeown of Fota Wildlife Park

Has a Taxon Management Group or Recovery Team been established?

Yes

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?

Yes

What tools are used to maximize retention of genetic diversity?

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?

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?

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

July 2022: Almost 500 Natterjack toadlets were released on July 25th, at Castlegregory, Co. Kerry, with the help of the local community. These included toadlets that had spawned in captivity – a first for Ireland and a major milestone in this joint conservation project to protect the endangered Natterjack between National Parks and Wildlife Service (NPWS) and Fota Wildlife Park. 2021: Under the captive rearing project, staff from NPWS, part of the Department of Housing, Local Government and Heritage, collect toad spawn and tadpoles from ponds in the wild, where mortality rates can be as high as 90%. They transport them to Fota where they are carefully looked after in special holding tanks over the summer months. Following metamorphosis, the resulting toadlets are then returned to the species’ native range in Kerry. Over 6,000 individuals have been successfully released into the wild to date.
