Reviewer(s): Cox, N.A. & Temple, H.J.

Population [top]

Population:Populations of this species are very fragmented, many of them confined to isolated mountains and valleys. It is relatively common in the Alcaraz, Segura, and Cazorla mountains, but it is rare in drier mountains (Filabres, Baza, Gádor), where it is associated with springs. Populations in drier areas can consist of only a few adults.
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:The species is present in pine and oak forests, most often on calciferous substrate, in open, very rocky landscapes. Adults occur in rock fissures and on stones next to water sources. Reproduction and larval development takes place in permanent mountain streams, man-made reservoirs and cattle troughs, and the larvae may take a long time to mature. Almost all known breeding habitats are human-modified water bodies.
Systems:Terrestrial; Freshwater

Threats [top]

Major Threat(s): The species is threatened by loss of suitable breeding habitat as a result of excessive water withdrawal, droughts, and modernization of agricultural practices leading to the abandonment of cattle troughs and other man-made water sources. A potential future threat is the fungal disease chytridiomycosis, which has already impacted the related Alytes obstetricans in Spain.

Conservation Actions [top]

Conservation Actions: This species is listed on Appendix II of the Bern Convention (as part of obstetricans). It is listed in regional Red Data Books and is present in the protected areas of Parque Nacional Sierra Morena, Parque Nacional de Sierra Nevada, and the Natural Park of Cazorla, Segura y las Villas. Protection measures in Castilla-La Mancha, Andalusia, such as restoration and construction of new breeding habitats, are under way.
