This species is listed as Vulnerable as this species has an extent of occurrence of only 5,944 km², occurs in only two threat-defined locations, and the extent and quality of its habitat is in decline.
Currently this species is known from only two localities: in Nam On river catchment in the Nakai-Nam Theun National Protected Area, Khammouan Province, Laos (Stuart et al. 2010) and Pu Hoat Proposed Nature Reserve in Nghe An Province, Viet Nam (Nishikawa et al. 2013). To date, the species has only been recorded from 980-1,000 m asl (Stuart et al. 2010), it has an estimated extent of occurrence (EOO) of 5,944 km² and it is thought to occur in two threat-defined locations.
Native:Lao People's Democratic Republic; Viet Nam

Eight individuals of this species are recorded in literature (Stuart et al. 2010, Nishikawa et al. 2013). Little information on its population is known except that it is likely to be fragmented.
|Current Population Trend:||Unknown|
|Habitat and Ecology:||This species is known from mixed moist forest consisting of evergreen, deciduous and coniferous species. Both known sites are located within well-protected areas and have undergone relatively little habitat disturbance (Nishikawa et al. 2013, Stuart et al. 2010). However it may also occur outside of these in similar, albeit disturbed, adjacent habitat. Adults are found in both the terrestrial environment, including on the forest floor, rocks and logs, and the aquatic environment, in slow-flowing streams. The species is known to reproduce around May, which involves the production of eggs that hatch as free-swimming larvae (Stuart et al. 2010).|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Movement patterns:||Not a Migrant|
|Use and Trade:||Related species are known to be popular in the pet trade and in traditional medicine (Rowley et al. 2010, Stuart et al. 2010). To date, there are no reports of Tylototriton notialis having been harvested for these purposes, however this may occur undetected.|
|Major Threat(s):||The species is only known from protected areas. However habitat loss and modification remain threats outside these protected areas. The species is also likely to be harvested for use in the traditional medicine and pet trades (Rowley et al. 2010).|
|Conservation Actions:||The species is only known from protected areas: Nakai-Nam Theun National Protected Area (Stuart et al. 2010), and Pu Hoat Proposed Nature Reserve (Nishikawa et al. 2013). Further research is needed on the species' population status, life history and ecology, and harvest levels to better understand the threats to the species. Monitoring of its population and habitat trends is also needed.|
