Taxon Name: Triturus marmoratus (Latreille, 1800) Common Name(s): • English: • Spanish:

Marbled Newt Tritón Jaspeado

Assessment Information Red List Category & Criteria:

Least Concern ver 3.1

Year Published:

2009

Date Assessed:

December 14, 2008

Justification: Listed as Least Concern in view of its wide distribution, tolerance of a broad range of habitats, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.

Previously Published Red List Assessments 2004 – Least Concern (LC)

Geographic Range Range Description: This species can be found in much of northern Iberia, and central, southern and western France. This species was introduced to the area of Turin, Italy but is now presumed to be extinct here (J.W. Arntzen pers. comm.). Present from sea level to elevations approaching 2,100m asl.

Country Occurrence: Native: France; Portugal; Spain

Population It is locally abundant in suitable habitat. It is locally endangered in central France, less threatened in southern France, and not particularly threatened in Spain and Portugal. Current Population Trend: Decreasing

Habitat and Ecology (see Appendix for additional information) Aquatic habitats include well-vegetated ponds, pools, ditches and streams generally within dry woodlands, heath land, fields and rough grassland. Breeding and larval development take place in many different types of permanent and temporary water sources, usually with aquatic vegetation for reproduction. It can occur in slightly modified habitats such as traditional farmland.

Systems: Terrestrial, Freshwater

Threats (see Appendix for additional information) Major threats are agricultural intensification, drainage, pollution, and eutrophication of aquatic habitats through intensive agricultural. Mass mortality of the species through disease (iridovirus) has been recorded in Carris Lake, Peneda-Gerês National Park, Portugal. The disease might be non-native and have been transferred to the lake by an introduced predatory fish (Lepomis gibbosus). Predation by L. gibbosus and other introduced predatory fish and crayfish (Procambarus clarkii) species is also a threat to T. marmoratus in parts of its range. There is some illegal collection of the species for the pet trade.

Conservation Actions (see Appendix for additional information) Protected by national legislation throughout its range (Gasc et al., 1997). Listed on Annex IV of the EU Habitats Directive. Listed on Annex III of the Bern Convention. Present in a number of protected areas. In Portugal it is present in Peneda-Gerês National Park where the population of Carris Lake has been severely impacted by disease. Further research into the impacts of disease on this species is needed. Reintroductions and/or translocations of this species have been made in the area of Madrid, Spain.
