2. The first sub-population occupies the Hang Cop Waterfall tourist recreation area which is highly influenced by the tourist activity. The second sub-population is a highly degraded forest near the local settlements. Both sites are considered as unique locations owing to independent threat at both places. And, there is observed decline in the quality of the habitat. Under following circumstances, the species can be assessed as Endangered, EN B2ab(iii) based on Red List IUCN guidelines (
