Assessment Information [top]

Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2014
Date Assessed: 2011-08-30
Assessor(s): Rao, D.-q. & Li, P.
Reviewer(s): Cox, N.A. & Bowles, P.
This species is listed as Near Threatened in view of its reliance on areas of hot springs at high altitudes (a restricted area of occupancy), although its extent of occurrence is much larger than 20,000 km2, and its population is is estimated to number 13,000 individuals, the extent and quality of its habitat is potentially threatened because of the construction of geo-thermal hydro-electric stations and human disturbance. It almost qualifies for a threatened listing under criterion B2ab(iii).

Population [top]

Population:Because of construction of geo-thermal hydro-electric stations and human disturbance, the population of this species is decreasing (Guo and Chen 2000). The population was estimated as 13,000 individuals (State Forestry Administration of China 2009).
Current Population Trend:Decreasing

Habitat and Ecology [top]

Habitat and Ecology:Very little information is available for this species. They live in rocks, streams, marshes and meadows near hot springs of 3,000 to 4,900 m altitude. Li (2007) found that this species mainly feeds on alpine frogs (Nanorana parkeri) and fish (Schizothorax o’connon and Triplophysa spp.) The female lays around six eggs. It might be ovoviparous.
Systems:Terrestrial; Freshwater
Continuing decline in area, extent and/or quality of habitat:Yes
