Listed as Endangered because of an observed population decline, estimated to be more than 50% over the last three generations, inferred from over-harvesting, observed shrinkage in distribution, and ongoing habitat destruction and degradation. The generation length is estimated to be five years.
|Range Description:||This species is known from south-western and central China in Sichuan, Yunnan, Guizhou, Hunan and possibly also Hubei Provinces. The only reasonably reliable records from mainland Southeast Asia are from Sa Pa (Bourret 1942, as Rana yunnanensis and R. phrynoides). Records from the Kakhien Hills of Myanmar may be a consequence of Bourret (1942) considering Paa feae a synonym. However, P. yunnanensis is recorded from most of Yunnan Province adjoining eastern Myanmar (Fei and Ye 1999). It probably occurs more widely than current records suggest. In China it is known from elevations of 1,500-2,950m asl, and in Viet Nam from 800-1,000m asl (Bourret 1942).|

|Population:||Although there are no available data on the population status of Southeast Asian populations, in China it is a common species (though it has declined significantly).|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||It has been recorded from rocky streams in high mountains in closed-canopy forest and grassland, and has also been found in ditches. The eggs are laid under stones in streams.|
|Major Threat(s):||Over-collecting for human consumption is the major threat to this species. It is also threatened by habitat destruction and degradation (caused by agricultural expansion), and water pollution.|
|Conservation Actions:||It is present in several protected areas in China. The two localities in Viet Nam are within Hoang Lien Son National Park and Tam Dao National Park. Studies of the intensity of harvesting of this species are required, and there is a need to ensure that the offtake of this species from the wild for human consumption is managed sustainably. Further survey work is needed to determine the population status of populations in Southeast Asia, and there is also a need for further taxonomic work to clarify the taxonomic status of frogs in the genus present in mainland Southeast Asia and the Himalayan foothills.|
