|Scientific Name:||Rana dybowskii Günther, 1876|
Rana semiplicata Nikolsky, 1918
Rana temporaria Günther, 1876 ssp. dybowskii
Rana zografi Terentjev, 1922
|Taxonomic Notes:||Further systematic studies of populations assigned to Rana dybowskii are needed. There are significant genetic and morphological distinctions between populations from the type territory of Rana chensinensis David, 1875 sensu stricto (Shaanxi Province of China) and the populations of the Rana chensinensis complex living further north-eastwards. The specific name Rana chensinensis David, 1875 should not be used for the frogs from the Primorye and adjacent territories; the name for these populations should be Rana dybowskii (S. Kuzmin pers comm.). Included in this account under Rana dybowskii are populations from Russia, the Korean Peninsula and Japan; it is possible that the populations of the Rana chensinensis complex from northern China are Rana dybowskii, but they are retained here in Rana chensinensis until this is confirmed.|
|Red List Category & Criteria:||Least Concern ver 3.1|
|Assessor(s):||Sergius Kuzmin, Vladimir Ishchenko, Irina Maslova, Natalia Ananjeva, Nikolai Orlov, Masafumi Matsui, Xie Feng, Yoshio Kaneko|
|Reviewer(s):||Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson and Neil Cox)|
Listed as Least Concern in view of its wide distribution, tolerance of a broad range of habitats, presumed large population, and because its population is unlikely to be in decline at present.
|Range Description:||This species is considered here to occur in the Russian Far East from near the confluence of the Zeya River into the Amur River eastwards to the Pacific coast and northwards to the southeast of East Siberia (Yakutia), the Democratic People's Republic of Korea, the Republic of Korea and Tushima Island in Japan. It might also occur in northern China, however further taxonomic studies are needed to confirm this. The altitudinal range of this species is sea level to at least 900m asl.|
Native:Japan; Korea, Democratic People's Republic of; Korea, Republic of; Russian Federation

|Population:||It is a widespread and common frog. Some localized population declines caused by habitat loss have been observed.|
|Current Population Trend:||Stable|
|Habitat and Ecology:||Although this species is generally associated with areas of broadleaf, coniferous and mixed woodland, it may also be found at the forest edge, in valleys, in wet lowland meadows and in paddy fields. It breeds in stagnant and slow-flowing waterbodies such as lakes, ponds, ditches, pools at stream edges and puddles. Animals may hibernate underwater in streams. It can be found close to human habitations.|
|Major Threat(s):||Some populations of this species have declined because of industrial pollution, urbanization and the construction of reservoirs. In the 1990s, mass collecting of R. dybowskii, mainly in the Primorye Region of Russia, for the trade in traditional Asian medicine led to population declines at a number of sites. Habitat destruction and degradation are major threats to this species.|
|Conservation Actions:||This species occurs in many protected areas.|
