Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This is an aquatic species usually found in shady habitats (with abundant vegetation) close to rivers, streams, lakes and marshes. The species' terrestrial habitats include woods, moors, meadows and areas of low scrub. In the north of its range it can occur down to sea level along slower flowing rivers. Breeding and larval development takes place within various shallow stagnant waterbodies.
Systems:Terrestrial; Freshwater

Threats [top]

Major Threat(s): Threats to this species include pressure from tourism development, urbanization of the lowland range, habitat loss through intensification of agriculture and deforestation and re-afforestation with non-native monocultures, introduction of non-native predatory fishes (salmonids) and mammals such as Neovison vison (American mink), desertification in southern Portugal, and habitat loss through hydroelectric projects. Recreational use by people of its habitats may cause disturbance to the species.

Conservation Actions [top]

Conservation Actions: It is present in Parque Natural del Gorbea and Parque Natural de Izki in Spain, where it is also protected by national legislation and listed in the national Red Data Book as vulnerable. This species is listed on Appendix II of the Bern Convention and on Annex IV of the EU Habitats Directive. There have been some recent reintroductions of captive-bred individuals in central Spain.
