Population [top]
Population: The population size of this species has not been quantified, but it has been described as generally uncommon.
Trend Justification: A moderately rapid population decline is suspected to be occurring as a result of habitat destruction throughout 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 semi-evergreen and evergreen forests to 1,675 m asl, but usually below 600 m asl. It extends into secondary woodland and plantations in areas with adjacent primary forest.
Systems: Terrestrial
Continuing decline in area, extent and/or quality of habitat: Yes
Generation Length (years): 19
Movement patterns: Not a Migrant
Threats [top]
Major Threat(s): Rates of forest loss in the lowlands of Indonesia 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 could have been allayed by this speciess tolerance of hill forest, which is under less pressure from logging and agricultural conversion.
Conservation Actions [top]
Conservation Actions: Conservation Actions Underway
CITES II listed.
Conservation Actions Proposed
Monitor populations across the species range to determine the magnitude of declines and rates of range contraction. Conduct studies to determine habitat associations and relative abundance in hill forest. Campaign for the protection of remaining tracts of lowland forest throughout the speciess range.
