Habitat:
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 can also be found close to human habitations. It breeds in stagnant and slow-flowing waterbodies such as ponds, ditches, pools at stream edges and puddles, and breeding season is from April to May (Fei et al. 2012). Tadpoles live in still ponds and slow running brooks (Fei et al. 2012). 

The generation length of this species is estimated to be three years.



Range:
This species occurs 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) and the Democratic People's Republic of Korea (DPR Korea). The species is known to occur as far south as Kaechon (39.7°) in DPR Korea, where the contact zone with Rana uenoi is expected, but it may also occur further south along the Baekdu Mountain Range (J.S. Choe pers. comm. June 2019). Its occurrence in northern China was uncertain in the last assessment, but has now been confirmed, and it is now known from northeastern China, south to southern Liaoning. Records from the Republic of Korea and Tsushima Island in Japan have now been attributed to R. uenoi (Matsui 2014). The elevational range of this species is from sea level to at least 950 m asl.

Conservation:
Conservation Actions In-Place
The species occurs in several protected areas in China, Russia, and Democratic People's Republic of Korea.

Research Needed
Further work is required on the species' taxonomy; in particular regarding the range limits and contact zones with other Rana species.
