The authority that recommended this species for an ex situ program

Servei de Biodiversitat, del Departament Agricultura, Ramaderia, Pesca, Alimentació i Medi Natural

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

Departament Agricultura, Ramaderia, Pesca, Alimentación i Medi Natural

Year the program started

2007

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

Francesc Carbonell of Departament Agricultura, Ramaderia, Pesca, Alimentación i Medi Natural

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

Knowledge have been gained in reproductive aspects, larval development and health aspects.

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).

No

If sufficient founders have not been collected, is there an ongoing search for additional founders?

Yes

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

Yes

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

2016: There is enough genetic evidence to differentiate two different ESUs (Western and Estern Sector). Genetic studies are being performed to define the genetic structure for each sector, depending on these additional founders will be caught. Reproductive evidence for the new populations released into the wild have been found. This program was initiated by the Servei de Biodiversitat, del Departament Agricultura, Ramaderia, Pesca, Alimentacio i Medi Natural (DAAM), Generalitat de Catalunya (Wildlife Service from the Catalan Government). Founder animals included 5 males and 5 females from the Western sector ESU and 6 males and 6 females from the Eastern sector ESU. A phylogenetic study has been carried out on wild populations to describe the species in Carranza and Amat (2005). There is enough genetic evidence to differentiate it from Calotriton asper. Preliminary studies (using Cyt b, ND4 and RAG-1 markers) for the ESUås definition (Valbuena-Ure_a et al., on preparation) suggest two different ESUås. Microsatellite studies are being performed to define the genetic structure of this species. Additional facilities will be required in the future. The recovery Plan is in elaboration process inside the general Management plan of species of fluvial habitats The captive breeding plan have been written by DAAM. We are pending genetic studies to determine ESUås and structure of genetic reserve. The first generation captive-bred animals did lay eggs but they failed to develop completely. We are just doing the first reintroductions in order to increase distribution.
