Population [top]

Population:This species is considered rare and the population is believed to comprise only 250-300 breeding females.
Current Population Trend:Decreasing
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:Breeding takes place only in the five small pools, with the breeding season running from end November to mid-March, which is the only time that adults can be found. Each female deposits 140-174 eggs, and the larvae develop in the pools; larvae take three years to reach sexual maturity.
Systems:Terrestrial; Freshwater

Threats [top]

Major Threat(s): The very small range and very limited number of breeding sites makes this species especially susceptible to habitat alteration, which is increasingly a problem due to the growing threat of human disturbance at the site, especially from touristic activities.

Conservation Actions [top]

Conservation Actions: Although the species is present in the small Longwangshan Nature Reserve, stricter management of the breeding sites is needed. A captive-breeding programme should also be established.
