Habitat:
Many terrestrial (associated with woodland) and aquatic habitat types are used. It is present in coniferous, mixed and deciduous forests, forested tundra and steppe, bush and shrublands, glades, grasslands, dry and wet meadows, marshes, fields, rural gardens, parks, and urban areas. Aquatic habitats include both temporary and permanent ponds, lakes and rivers; spawning and larval development occurs in these waterbodies. It does well in many modified habitats such as rural gardens.

Range:
This species is widespread throughout most of Europe, ranging from northern Spain to the Urals (absent from southern and central Iberia, much of southern Italy [scattered Apennine subpopulations]), eastwards to European Russia and through northern Greece and Bulgaria. It has a patchy distribution in the mountainous parts of the Balkans. It has been recorded from sea level to elevations approaching 2,700 m asl (Pyrenees).

The range extends eastwards of the European region to the western part of West Siberia and northern Kazakhstan.

Following genetic analysis, subpopulations from northwestern Spain have been assigned to Rana parvipalmata which was elevated from the subspecies of this species (Dufresnes et al. 2020).

Conservation:
Conservation Actions In-Place
This species is present in many protected areas. It is listed on Appendix III of the Berne Convention and on Annex V of the EU Natural Habitats Directive. It has been recorded in a number of national and sub-national Red Data books and lists and is protected by national legislation in a number of countries. It is considered Vulnerable in Czech Republic (Chobot and Nemec 2017), Slovenia (Anonymous 2010), Romania (Botnariuc and Tatole 2005) and Greece (Legakis and Maragou 2009), Near Threatened in Austria (Gollmann 2007), Hungary (Halpern et al. 2019), Bosnia and Herzegovina (Đug 2013) and Serbia (Kalezić et al. 2015). In parts of its range, mitigation measures to reduce road kill have been established (see in: Schmidt et al. 2020). There were six EC-funded LIFE-projects targeting the species or its habitats: https://webgate.ec.europa.eu/life/publicWebsite/search/get basicSearchText=rana+temporaria

Evidence shows that successful conservation action is possible for this species (Moor et al. 2022).

Conservation Needed

Water management should target the restoration of water bodies, serving as breeding habitat for the species throughout its range, but especially within EU Natura 2000 network.

Research Needed

Monitoring of populations for the presence and effects of Bd infection or other emerging pathogens need to be organised throughout its range.
