This species was originally known only from the Tam Dao mountain ridge in northern Viet Nam. It has now been found in more than ten localities in Bac Kan, Ha Giang, Yen Bai, Tuyen Quang, Tay Nguyen, and Lao Cai Provinces, all in Viet Nam. It occurs from about 600-1,200m asl.
Habitat and Ecology
It inhabits streams in evergreen hill forest, including small natural and artificial impoundments. It breeds in small pools in streams where larval development takes place.
Its population apparently is relatively stable, and it is not particularly rare locally.
Habitat loss, due to agriculture and human settlement, pollution, and harvesting for food, medicine and the pet trade, are threats to this species.
This species is found in Tam Dao, which is an undefined National Park, and has also been found in Ba Be National Park. There are two locations west of the Red River, Lao Cay and Yen Bai that are in a region proposed for a National Park. It is included under Viet Nam protective legislation. Setting up managed ex-situ assurance colonies among zoos and competent hobbyists is recommended.
