Assessment Information [top]

Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2009
Date Assessed: 2008-12-14
Assessor/s: Pedro Beja, Jaime Bosch, Miguel Tejedo, Paul Edgar, David Donaire-Barroso, Miguel Lizana, Iñigo Martínez-Solano, Alfredo Salvador, Mario García-París, Ernesto Recuero Gil, Tahar Slimani , El Hassan El Mouden, Philippe Geniez, Tahar Slimani
Reviewer/s: Cox, N. and Temple, H.J. (Global Amphibian Assessment)
Justification:
Listed as Near Threatened because this species is probably in significant decline (but probably at a rate of less than 30% over ten years) because of widespread habitat loss through much of its range, and the effects of invasive species, thus making the species close to qualifying for Vulnerable.
History:
2006 Near Threatened (IUCN 2006)
2006 Near Threatened
2004 Least Concern

Geographic Range [top]

Range Description: This species is distributed in central and southern Iberia, and in the coastal plain of northern Morocco. It is essentially a lowland species becoming rare above 900m asl, although it might be found at 1,565m asl in the Sierra de Loja, Granada, Spain.
Countries:
Native:
Morocco; Portugal; Spain
Introduced:
Gibraltar

Population [top]

Population: It is not abundant over most of its distribution, with populations being more scattered and fragmented in the east and north of the Iberian Peninsula. Some population declines in this species have been observed, especially in eastern Spain. It appears to be in decline in Morocco (although it is common in the north), and the southernmost populations in Morocco might be extinct (T. Slimani and El Hassan El Mouden pers. comm.).
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: This is a highly aquatic species of Mediterranean-type habitats including scrub, open woodland and cultivated land. It is generally found in ponds, dayas, wadis, lakes, ditches and slow-moving streams (often temporary in nature) with plenty of vegetation cover. The adults are mostly found under stones or in mud in their aquatic habitats, or sheltering under cover on land if the wetland dries up. It may be present in slightly modified aquatic and terrestrial habitats. The female deposits around 800-1,500 eggs on plants and stones in ponds.
Systems: Terrestrial; Freshwater

Threats [top]

Major Threat(s): This species is generally threatened through loss of aquatic habitats through drainage, agrochemical pollution, the impacts of livestock (in North African dayas), eutrophication, domestic and industrial contamination, and infrastructure development. It has largely disappeared from coastal areas in Iberia and Morocco close to concentrations of tourism and highly populated areas (such as Madrid). Introduced fish and crayfish (Procambarus clarkii) are known to prey on the eggs and larvae of this species, and are implicated in its decline. Mortality on roads has been reported to be a serious threat to some populations.

Conservation Actions [top]

Conservation Actions: It occurs in a number of protected areas in Iberia, but there is a need to monitor vulnerable populations in northern and eastern Spain and Portugal. It is listed on Appendix III of the Berne Convention and is protected by national legislation in Spain, where captive breeding of the species and habitat restoration projects are in place in some regions.
