Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2009
Date Assessed: 2008-12-14
Assessor(s): Kuzmin, S., Beebee, T., Andreone, F., Nyström, P., Anthony, B.P., Schmidt, B., Ogrodowczyk, A., Ogielska, M., Cogalniceanu, D., Kovács, T., Kiss, I., Puky, M. & Vörös, J.
Reviewer(s): Cox, N.A. & Temple, H.J.
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:

Geographic Range [top]

Range Description:This species is distributed over much of Europe, ranging as far east as the southern Ural Mountains of Russia. It is absent from the Iberian Peninsula (except for introductions to Spain in Cáceres [Villasbuenas de Gata] and unspecified localities in Galicia, Cataluña and Comunidad Valenciana), much of Scandinavia, central and southern Italy (exact distribution not known but thought to be replaced by P. bergeri) and it is absent from the Balkans. There are two isolated relict populations - one near Oslo (Norway) and Uppland (Sweden) north of Stockholm. It is native (formerly extirpated) to the British Isles and has been recently reintroduced from Sweden. It might occur up to 1,550 m asl in southern parts of its range.
Countries occurrence:
Austria; Belarus; Belgium; Bosnia and Herzegovina; Croatia; Czech Republic; Estonia; France; Germany; Hungary; Italy; Latvia; Liechtenstein; Lithuania; Luxembourg; Moldova; Montenegro; Netherlands; Norway; Poland; Romania; Russian Federation; Serbia (Serbia); Slovakia; Slovenia; Sweden; Switzerland; Ukraine
United Kingdom

Population [top]

Population:Although this species is reported to be declining over much of its European range (Gasc et al. 1997), it remains widespread and common in Poland, the Baltic Republics, Moldova, Russia and the Ukraine.
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:It is present in deciduous and mixed forests, forest steppe, steppe, bush lands (e.g. riparian alder groves), meadows, fields and fens. It may often be found in shallow stagnant waterbodies (usually without fish) such as lakes, ponds, swamps, large puddles, clay and gravel pits, and ditches, often covered with dense herbaceous vegetation. It breeds in these wetlands, but may be found hibernating away from waterbodies. It is not very adaptable, but can occur in slightly modified habitats.
Systems:Terrestrial; Freshwater

Threats [top]

Major Threat(s): It is threatened by habitat loss through agricultural intensification and urbanization, channelization of waterbodies, drainage and pollution of wetlands, and the introduction of predatory fishes to breeding sites. It is additionally threatened by afforestation (in northern parts of the range) and competition with the larger sympatric R. ridibunda. The frog-leg trade (which is increasing) and high levels of pollution are leading to significant declines in populations within Yugoslavia (Dzukic 1996, Ljubisavljevic et al. 2003).

Conservation Actions [top]

Conservation Actions: It is listed on Appendix III of the Bern Convention and on Annex IV of the EU Natural Habitats Directive. It is protected by national legislation in many countries and is recorded on a number of national and sub-national Red Data books and lists. It is present in many protected areas. In parts of the species' range, mitigation measures to reduce road kill have been established.
