Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2009
Date Assessed: 2008-12-14
Assessor(s): Jose Antonio Mateo Miras, Marc Cheylan, M. Saïd Nouira, Ulrich Joger, Paulo Sá-Sousa, Valentin Pérez-Mellado, Benedikt Schmidt, Andreas Meyer, Roberto Sindaco, Antonio Romano, Iñigo Martínez-Solano
Reviewer(s): Cox, N. and Temple, H.J. (Global Reptile Assessment)
Listed as Least Concern in view of its wide distribution, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.

Geographic Range [top]

Range Description:In Europe, this species ranges from Portugal and Spain through much of France, to extreme southwestern Switzerland and northwestern Italy. In North Africa it is present in most of Morocco, northern Algeria, northern and central Tunisia and northwestern Libya. This species is also present (probably allochtonous) on the Mediterranean islands of Sardinia (Italy), Corsica (one single record) [not mapped]; natural populations are present on Iles d'Hyéres (France) and La Galite (Tunisia). It has been introduced to the islands of Menorca and Mallorca in the Balearic Islands of Spain. The species can be found from sea level up to 2,600 m asl.

Population [top]

Population:In most of its range it is an extremely common species, but perhaps declining locally in some parts of North Africa.
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This species is generally found close to, or within, waterbodies such as streams and ponds. Often these habitats are in meadows and open woodlands. It has also been recorded from areas of brackish water. The species lays between three and 20 eggs.
Systems:Terrestrial; Freshwater

Threats [top]

Major Threat(s): It is threatened in parts of its range by aquatic pollution, especially through the loss of prey species (e.g.. fishes). It is threatened in Switzerland, and presumably other parts of the species range, by channelization of rivers and other waterbodies. As with many snake species, individual animals are occasionally killed by people, as they are often confused with venomous vipers. In Tunisia, desiccated specimens are sold as souvenirs to tourists (Juan M Pleguezuelos pers. comm., October 2008).

Conservation Actions [top]

Conservation Actions: This species is listed on Annex III of the Bern Convention, and is protected by national legislation in Switzerland. It is present in many protected areas. This species is categorized as Critically Endangered in Switzerland (Monney and Meyer, 2005).
