Conservation Actions

Conservation Actions
It occurs in the Lipaso Protection Forest Reserve, but this is probably not being managed adequately for the purpose of biodiversity conservation.

Conservation Needed
More effective protection and preservation of mid-elevation forests and riparian forest in the vicinity of Lipaso Forest Reserve is essential.

Research Needed
Further survey work is needed to determine the population status of this species and whether it occurs more widely.

Location Information

The species is known only from the type locality: the bank of a small tributary of Sungai Liwagu, in the Lipaso Protection Forest Reserve, Labuk and Sugut District, Sabah, in Malaysian Borneo. It has been recorded at 310 m asl, its estimated extent of occurrence (EOO) is 29 km2, and all individuals occur in a single threat-defined location.

Population Information

There is no information on the population status of this species, but it appears to be rare. There is likely suitable habitat in other riparian areas of the reserve where the species may occur, however the only access to the reserve is through the palm plantations and permission to conduct surveys in the reserve has not been granted (P. Yambun pers. comm. January 2018). Due to ongoing decline in the extent and quality of habitat caused by oil palm plantations, the population is suspected to be decreasing.

Threats

The main threat to the species is habitat loss, as the lowland forest around the type locality of this species has been subject to clearing for oil palm plantations (P. Yambun pers. comm. January 2018). This clearing is also thought to threaten the species by causing siltation of the streams, which eliminates the larval feeding microhabitat of this species.
