Habitat and Ecology [top]

Habitat and Ecology:This species was recorded in "dense viney roadside secondary brush on an abandoned logging road" in what remained of primary lowland dipterocarp forest, which is the dominant habitat in the surrounding region (Musser and Carleton 2005). The species is restricted to lowland forests and appears to be logging-intolerant (Meijaard and Sheil 2008).

Threats [top]

Major Threat(s): The species is restricted to lowland forests and appears to be logging-intolerant (Meijaard and Sheil 2008), but has been recorded from degraded habitats so would appear to be somewhat adaptable. Sabahs lowland forests have been heavily logged and what remains is highly degraded, however, protected areas are expanding, particularly around Danum Valley (Reynolds et al. 2011).

Conservation Actions [top]

Conservation Actions: The only known specimen is from the Danum Valley Protection Forest Reserve. There is a need for additional survey work to determine the current population status of this species.

Errata [top]

Errata reason: This errata assessment has been created because the map was accidentally left out of the version published previously.
