This natural distribution of this species is restricted four islands (Lantau, Lamma, Chek Lap Kok and Po Toi) in Hong Kong. As mitigation of the effects of airport construction on Chek Lap Kok, the Chek Lap Kok population was translocated to suitable sites on Hong Kong Island and the New Territories (including Tsiu Hang Special Area, Tai Lam Country Park and Tai Po Kau Nature Reserve). It occurs from sea level to 650m asl.
Habitat and Ecology
It inhabits forests, old plantations and nearby streams and marshes, but does not occur in open areas. Breeding takes place in shaded temporary pools, marshes, seepages, slow-flowing stream pools, ponds and water-filled small containers.
Of the eight new sites to which populations were translocated, only seven still hold breeding populations.
Infrastructure development for human settlement and the construction of an airport are the major threats to the species' habitat.
Some major strongholds for this species are listed as Sites of Special Scientific Interest, and all translocated populations have been released into protected areas. This species is also protected in Hong Kong. There was a successful collaborative breeding and release programme involving Melbourne Zoo, WWF Hong Kong, the University of Hong Kong and the Kadoorie Farm and Botanic Gardens. Monitoring of wild populations is ongoing.
Red List Status
Listed as Endangered because its extent of occurrence is less than 5,000 km2 and its area of occupancy is less than 500 km2, its population is severely fragmented, and there is a continuing decline in the extent and quality of its habitat, and in the number of subpopulations, in Hong Kong.
