Habitat:
This species is a habitat specialist; it is adapted to the upper reaches of small mountain streams in both coniferous and mixed cedar pine and broad-leafed forests. Inhabited streams have both a thick bed of pebbles and rich, humid vegetation on moist banks surrounding the streams. Animals are present in the stream sections that have minimal direct sunlight, a maximum size of pebbles and abundant hiding places, such as holes under logs, snags, and large stones. It may also be found in underground spring habitats. It breeds in streams; larval development takes place in the streams. The species is very sensitive to habitat change.
Range:
This species was previously known from north-eastern China, the Democratic People's Republic of Korea (DPRK), the Republic of Korea and the Russian Far East (part of Sikhote-Alin Mountains in the south of Primorye Region). Following a series of taxonomic changes, this species is now only known from the Russian Far East, part of Sikhote-Alin Mountains in the south of Primorye Region, around 200 m asl (I. Maslova pers. comm. July 2018). While its extent of occurrence (EOO) is 35,945 km2, its area of occupancy is thought to be much less than that. All boundaries of this species' range are well-defined based on studies carried out in 2000–2001 and 2017–2019, and it is estimated that the total amount of habitat within its distribution is just under 10,000 km2 (I. Maslova pers. comm. March 2022). It is possible that its AOO is less than 2,000 km2 as there are areas within its distribution where the species does not occur for various reasons, however, an exact estimate cannot be made at this time and further research needs to be carried out (I. Maslova pers. comm. March 2022).
Subpopulations from Baekdu Mountain Range in the Republic of Korea into the DPRK have been assigned to Onychodactylus koreanus (Min et al. in Poyarkov et al. 2012), subpopulations from Changbaishan Mountain, Jilin Province, China and in the north of the DPRK have been assigned to O. zhangyapingi (Poyarkov et al. 2012), and subpopulations from Qianshan Mountains and the mountain areas of Liaonong Peninsula in Liaoning Province of China and in the north west of the DPRK have been assigned to O. zhaoermii (Poyarkov et al. 2012, J.S. Choe and T.Y Nam pers. comm. June 2019). The contact zone between this species and O. koreanus is not known; therefore the identity of the records for both of the species in the DPRK is treated as uncertain (A. Borzée pers. comm. December 2017).

Conservation:
Conservation Actions In-Place
The range of this species overlaps with a number of protected areas in Russia. It is listed in the Red Data Book of Russia.
Conservation Actions Needed
Habitat protection is required to prevent further degradation of the sensitive and critical habitat of this species.
Research Needed
Further research into the monophyly of the clade (Poyarkov et al. 2012) is required, as well as studies on the species' breeding behaviour and ecology.
