Population [top]
Population: The population size of this species has not been quantified; it is considered scarce to common throughout its range.
Trend Justification: A moderately rapid population decline is suspected to be on-going as a result of continuing forest loss and degradation across the speciess range.
Current Population Trend: Decreasing
Additional data:
? Number of mature individuals: Unknown ? Continuing decline of mature individuals: Yes
? Extreme fluctuations: No ? Population severely fragmented: No
? Continuing decline in subpopulations: Unknown
? Extreme fluctuations in subpopulations: No ? All individuals in one subpopulation: No
Habitat and Ecology [top]
Habitat and Ecology: This species occurs in primary lowland evergreen forest up to 800 m asl. It is also found in tall secondary forest, poor-quality Dipterocarp slope forest and occasionally in rubber plantations.
Systems: Terrestrial
Continuing decline in area, extent and/or quality of habitat: Yes
Generation Length (years): 8.5
Movement patterns: Not a Migrant
Threats [top]
Major Threat(s): Rates of forest loss in the Sundaic lowlands have been extremely rapid, owing partly to the escalation of illegal logging and land conversion, with deliberate targeting of all remaining stands of valuable timber including those inside protected areas. Forest fires have also had a damaging effect (particularly in 1997-1998). The magnitude of these threats may be allayed by this speciess tolerance of secondary and slope forest, although further studies are required to determine whether this species can genuinely persist in these habitats in the absence of adjacent primary habitat.
Conservation Actions [top]
Conservation Actions: Conservation Actions Underway
No targeted conservation actions are known for this species, although it occurs in a number of protected areas.
Conservation Actions Proposed
Conduct repeated surveys across the speciess range to determine the magnitude of declines and rates of range contraction. Conduct ecological studies to determine precise habitat requirements, tolerance of secondary habitats and response to fragmentation. Campaign for the protection of remaining tracts of lowland forest throughout the speciess range.
