Conservation Actions

Conservation Actions
It may occur in the recently gazetted Pulong Tau National Park, but this requires confirmation. However, there is no current infrastructure or field staff in place and is not considered to be well-protected national park at present (I. Das pers. comm. March 2018).

Conservation Needed
Improved habitat protection is required at sites where this species is known to occur. The enforcing of the national park's boundaries need to be enforced to address the issues of logging with the park (Malaysia Red List Assessment Workshop January 2018).

Research Needed
Further research is required on the distribution, population status, and ecology of this species.

Location Information

This species is only known from its type locality of Bario, Kelabit Highlands in Sarawak, Malaysia, at 1,150 m asl (Hamidy and Matsui 2014). Its extent of occurrence (EOO) is 10 km2 and all individuals occur at a single threat-defined location.

Geographic Range



Population Information

Little is known about its population status and trends, however due to ongoing decline in the extent and quality of habitat the population is suspected to be decreasing.


Small-scale subsistence rice agriculture and small-scale subsistence logging are threats to this species' habitat (I. Das pers. comm. March 2018). In 2016, a road joining Miri to Bario was established within the species' range and tourism development has become a threat; if it continues to expand then forest clearance will continue to be a problem (I. Das pers. comm. March 2018). Logging may also increase within this area, with the development of new roads making the forest more accessible (I. Das pers. comm. March 2018). The habitat in Pulong Tau National Park faces encroachment from logging companies, as it has only been recently gazetted (in the last 2-3 years) and there is no current infrastructure or field staff in place, so it is not well protected at present (I. Das pers. comm. March 2018).
