Yushan National Park
In its Red List of Threatened Species, the IUCN lists "Hynobius arisanensis" as being "vulnerable". This is because it is restricted to the Alishan, Yushan and Pei Ta Wu Shan mountain ranges in Taiwan where its range is fragmented. Its total area of occupancy is less than and its habitat is being degraded, particularly from the infrastructure development being undertaken in an attempt to increase tourism in the region. It is present in the Yushan National Park and the Tawushan Nature Preserve which should provide some measure of protection.
