Justification of Red List category
Although this species may have a restricted range, it is not believed to approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence under 20,000 km² combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (under 10,000 mature individuals with a continuing decline estimated to be over 10% in ten years or three generations, or with a specified population structure). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (over 30% decline over ten years or three generations). For these reasons the species is evaluated as Least Concern.
Population justification
The global population size has not been quantified, but the species is described as sparsely distributed (Madge and McGowan 2002). This species is considered to have a high dependency on forest habitat, and tree cover is estimated to have declined by 3.3% within its mapped range over the past three generations (Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). It is therefore tentatively suspected that this rate of cover loss may have led to a decline of between 1-19% in the species' population size over the same time frame, with a best estimate of reduction being less than 5%.
Trend justification
.
This species is restricted to the mountains of Peninsular Malaysia.
The species occurs in the upper dipterocarp zone, as well as in montane evergreen forest and tall upper montane forest.
As a result of the inacessability of much of its range the species is thought unlikely to be affected by habitat loss, although further studies are required in order to determine whether any population declines are occurring.
