IUCN (Red List) status: Near Threatened (NT).
For Red List information on this species, see the IUCN species account.

From the IUCN Red List Species Account:   Range Description This species is known from the type locality, Pangnamdim, in northern Myanmar, which is 910m asl (Dubois 1975), and from adjacent Xizang Autonomous Region and north-western Yunnan Province, China, from 1,000-2,080m asl. It probably ranges slightly more widely, especially in Myanmar. Habitat and Ecology In China this species is known from medium and small streams in forested areas, and sometimes also from springs near paddy fields. It breeds in streams, the eggs being laid in water under stones. There is no information on its recorded habitat in Myanmar. Population This species is considered uncommon in China. In Myanmar, it has not been collected again since the type series was collected in the 1930s. Results from recent surveys of the area are not yet available (G. Wogan pers. comm.). Population Trend Decreasing Major Threats The main threat in Myanmar to this species and most of the species in its genus is local consumption. In China it is threatened by habitat destruction and degradation, in particular due to agricultural development and the subsistence collection of wood. Conservation Actions A few protected areas are present within the range of this species, including Hkakabo Razi National Park in Myanmar (which is the type locality), and Gaoligongshan National Nature Reserve in China. Further herpetological surveys of northern Myanmar are needed to determine the range of this species in this country. Further research is also needed to resolve the confusion relating to the nomenclature and taxonomy of this species. Taxonomic Notes Paa chayunensis is considered here to be a synonym of this species, following Zhao and Adler (1993), until the taxonomic confusion surrounding this species is resolved. There is much confusion relating to the nomenclature and taxonomy of this species. Taxonomic revision should include Nanorana mokokchungensis from India and N. maculosa chayuensis from China.
